HSE-Challenges i. ii. iii. iv. v. vi. vii.
Health, safety and Environment is a subject of Global concern, Nature Vs. Human activities: nature has no ultimate waste, Nature is full of cycles, Nature is a system of infinite life technologies where there is total interdependence, harmony and balance, The first Law of nature is no ultimate waste, All human activities end up with wastes, The main HSE-Challenge is how we can respect the laws of Nature and blend and harmonize with nature. Each specific HSE-Challenge has to address this basic need to blend and harmonize with Nature.
The Fundamental Laws of Nature: Nature is a system of infinite “Technologies” producing infinite range of complex products in life systems where there in neither a single waste product nor any dead end product for which no use exists! Everything proceeds in cycles. There is the primary Oxygen-Carbon dioxide cycle that keeps plant and animal life going perpetually.

the water cycle, food or nutrient cycle or chain as it is called, carbon cycle, scavengers that eat up waste and so on. This harmony and cyclic system ensures perpetual selfsustaining development. These Nature’s fundamental laws are the essential laws that need to be followed by man in all his developmental activities to ensure a sustainable development. In other words, we have to blend our development in harmony with the Nature’s laws. We have systematically violated these laws of nature and continuing to do so since the beginning of civilization 10,000 years ago. The wonderful Ecosystem with no waste but interdependence, Harmony and Balance! Let us blend and harmonise our selves for our own good and preservation of the Ecosystem. SUN Manure produced from decomposers feeds plants in turn completing the cycle.

Contributors to Global warming: The major natural greenhouse gases and their contributions to Global Warming are: i. ii. iii. iv.
Water vapour: 36-70% Carbon dioxide: 9-26%, Methane: 4-9%, Ozone: 3-7%
1. Carbon dioxide, methane, nitrous oxide and three groups of fluorinated gasses (sulfur hexafluoride, HFCs, and PFCs) are the major greenhouse gases and the subject of the Kyoto Protocol, which entered into force in 2005. 2. CFCs, although greenhouse gasses, are regulated by the Montreal Protocol, which was motivated by CFCs' contribution to ozone depletion rather than by their contribution to global warming. Note that ozone depletion has only a minor role in greenhouse warming though the two processes often are confused How Global warming takes place? When sunlight reaches the surface of earth some of it is absorbed and warms the earth. Because the Earth's surface is much cooler than the sun, it radiates energy at much longer wavelengths than does the sun and cools down again. The atmosphere however, absorbs these longer wavelengths more effectively than it does the shorter wavelengths from the sun. The absorption of this long wave radiant energy (Heat waves) warms the atmosphere; the atmosphere also is warmed by transfer of sensible and latent heat from the earth’s surface. Greenhouse gases also emit long wave radiation both upward to space and downward to the surface and laterally. The downward and lateral part of this long wave (Heat) radiation emitted by the atmosphere traps heat and is the "greenhouse effect causing warming.

Environmental Sustainability Index (ESI): ESI Is a measure of the Environmental Sustainability developed by Yale University, in collaboration with World Economic Forum, Geneva, and Joint Research Centre, European Commission, Ispra, Italy in 2005.. It provides a composite profile of Environmental stewardship based on a compilation of 76 - indicators derived from 76 underlying data sets. Finland with ESI - Score of 75.1%, ranks highest among all countries for ESI - Ranking but no country is on the “Sustainability - Trajectory” meaning there is no 100% score for any country! There are 5 - Countries scoring more than 70% in ESI - Score namely Finland, Norway, Uruguay, Sweden and Iceland and 11 Countries scoring 60s, 21 - Countries scoring 50s, 36 - Countries scoring above 40 % in which India lies at a score of 45.2%.

Finally what you and I can do to prevent Global warming: I have seen Text Books written for School Children in India and Abroad. All these talk of Global warming, Glacier melting, Ozone layer depleting, Sea level rising and Underground water level falling and so on. No where there is any mention on what the individual should do at his/her level to contribute to reduction in Global warming. Individuals can contribute to reduction in Methane levels in the atmosphere and thereby contribute to reduction in Global warming. Methane is produced by the individuals in not segregating kitchen waste in to biodegradable and non-biodegradable at source and clean all contaminated non-biodegradable. This enables recycling all non-biodegradable waste and composting of biodegradable. If this is not done by individuals, garbage has to be dumped and these garbage dumps evolve methane, carbon dioxide contributing to Global warming. Advanced countries are working on Zero dumping. There are no dumping grounds available. Supreme court has directives on all Municipal Solid Waste to be segregated and contaminated items cleaned for recycling. But who is following? Does the Judges do it in their homes, does Canteen? Who is following? Methane is 21 times more potent heat trap as compared to carbon dioxide!

Sustainable Development: A term commonly defined as “Economic and Social development that meets the needs of the current generation without undermining the ability of future generations to meet their own needs”. This almost universally quoted definition was produced in 1987 by the World Commission on Environment and Development (WCED), otherwise known as the Brundtland Commission (after its Chairwoman, Gro Harlem Brundtland, Prime Minister of Norway). In simple terms, sustainable development means “Achieving a quality of life that can be maintained for many generations” The essential features of a sustainable development are the following: i.
Renewable resource reserves of Nature: To be maintained and enhanced. These include: a. b. c. d.
ii.
Forest wealth, Water resources (Water cycle and pollution control), Air resource (Oxygen-CO2 cycle and pollution control), Soil resources (Conserve Flora and fauna and Pollution control).
There is however, a renewal time in each case: A forest tree cut can be renewed only after a decade or so. A seasonal crop can be renewed each season. Water is renewed in cycles according to rainy days, air is renewed day and night plants converting Carbon dioxide to Oxygen and man and

Non-renewable resources reserves: Coal, petroleum, natural gas and nuclear. These would get exhausted one day. Alternatives need to be found. Ultimate solution is in sustaining renewable sources of energy and exploiting perpetual sources of energy.
iv.
Perpetual sources of energy: Solar energy, wind, hydro power and geothermal energy are inexhaustible till the sun exhausts its nuclear fusion reaction converting hydrogen to helium and earth cools down when all life on earth ends. So in a sense nothing is perpetual!
Stages in the evolution of the concept of “Sustainable development”: Since the mid 1970s, sustainable development has emerged as the preferred way of dealing with the rapid degradation of the natural environment. The first global meeting on this issue, the U.N. Conference on the Human Environment in 1972, focused mainly on the environmental issues, such as pollution and waste, The new concern for what later became labelled “sustainable development” is evident in the Cocoyoc Declaration of 1974, which addressed the issue of how to respect the “inner limit” of satisfying fundamental human needs within the “outer limits” of the Earth’s Carrying capacity (see 1.2.4 for definition) It was the World Conservation Strategy of 1980 that launched sustainable development into the international policy arena, stressing the importance of integrating environmental protection and conservation values into the development process. The Brundtland Commission then paved the way for the UN Conference on Environment and Development (UNCED), otherwise known as the Earth Summit, in Rio de Janeiro in 1992. This conference approved a set of five agreements: a.
Agenda 21—for the 21st Century, a global plan of action for sustainable development, containing over 100 programme areas, ranging from trade and environment, through agriculture and desertification, to capacity building and technology transfer.
b.
The Rio Declaration on Environment and Development—a statement of 27 key principles to guide the integration of environment and development policies (including the polluter pays, prevention, and precautionary and participation principles).
c.
The Statement of Principles on Forests—the first global consensus on the management, conservation, and sustainable development of the world’s forests.

d.
The Framework Convention on Climate Change—a legally binding agreement to stabilize greenhouse gases in the atmosphere at levels that will not upset the global climate.
e.
The Convention on Biological Diversity—a legally binding agreement to conserve the world’s genetic, species, and ecosystem diversity and share the benefits of its use in a fair and equitable way.
Achieving a Sustainable development: Sustainable development will entail integration of the following three objectives: Ecological sustainability of resources in the long term: Economical viability of ecological sustainable technologies, Ability to meet social aspirations equitably. Trade offs: A pragmatic way of tackling the question “how best to achieve sustainable development?” is to start with the premise that development intrinsically involves tradeoffs between potentially opposing goals, such as between economic growth and resource conservation, or between modern technology and indigenous practices. These conflicts are often real, but vary according to circumstances. Poverty is frequently cited as a cause of environmental degradation, but there are many examples of poor societies improving their environment. The aim of sustainable development is thus to optimize the realization of a society’s many different social, environmental, and economic objectives at one and the same time. Preferably, this should be achieved through an adaptive process of integration, but more usually it will require bargains (trade-offs) struck amongst the different interest groups concerned. Critical to this process is the recognition that different perspectives on environment and development are both inevitable and legitimate. There could be, for example, very different environmental priorities between aid donors, recipient governments, and the poor of developing countries. All these are currently debated in several UN and intergovernmental agencies. The Carrying Capacity and The Limiting Factors: The limiting capacity of the Ecosystem to remain in balance and harmony with addition of population, resource consumption and pollution. The Limiting Factors: The Ecological delicate balance depends on a wide range of closely related factors like temperature, Oxygen-CO2 balance, ground water levels, harmony of food chain (see 1.5 below) through Trophic hierarchical proportion e.g. insect-bird population, cattle vs. grazing land proportion etc. and so on. Any change in the Ecological balance affects several features of the Ecosystem (see 1.4.4 on Ecological Balance).

Limits to Growth: Civilizations have grown to a peak and vanished-The Greek civilization, the Roman Empire, Harappan civilization and so on. The simplest of limits to growth is the traffic control systems at road crossings. During very low traffic of pedestrians and bullock carts, simple road crossings without any control did very well. As traffic density and speed grew the simple crossings failed. This led to roundabouts at road crossings. This did well for some decades. Then they reached a peak and failed. Then came traffic signals which are failing now and being replaced by flyovers and butterfly crossings. Are these the final solutions? Nobody knows. Air traffic at major airports has reached a peak. Space ventures have created debris that is creating concerns. Dinosaurs ruled the globe at one time and suddenly vanished for causes not precisely known as yet. The Club of Rome issued the first “Limits to Growth” concept for industrial growth. The following diagram Limits to Growth (Source: “Beyond the Limits” by Meadows et al): The prediction by computer modelling shows the collapse should start in a couple of decades. The predictions are based on Carbon energy system of economy of nonrenewable resources. If a break through is made to change to a perpetual source of infinite energy based on Nuclear Fusion Technology and Hydrogen as fuels, then the scenario can change dramatically which is likely to happen in the next few decades if not before the collapse of carbon based economy starts collapsing. So there is hope and mans ingenuity has no limits! But there are limits to other non-renewable resources like minerals where recycling is a potential answer in a limited way. 2025

(ISO-14001 Clause-3.2). The set of circumstances or conditions, esp. physical conditions, in which a person or community lives, works, develops, etc., or a thing exists or operates; the external conditions affecting the life of a plant or animal. Also, physical conditions viewed in relation to the possibility of life. (Oxford Talking Dictionary) ii.
Ecosystem:
A community of interdependent organisms and the environment they inhibit. (Text book definition), A relatively self-contained, dynamic system composed of a natural community along with its physical environment. (Microsoft Encarta Encyclopaedia 2003), iii.
The concept of Ecosystem:
First developed in the 1920s and 1930s, takes into account the complex interactions between the organisms—plants, animals, bacteria, and fungi—that make up the community and the flows of energy and matter through it. (Microsoft Encarta Encyclopaedia 2003), iv.

Environmental Aspect and Impact: The following are the formal definitions of Aspect and Impact under ISO-14001: i. Environmental Aspect: The word “Environmental Aspect” never came up in Text Books on “Environmental Engineering” taught since decades. The word made its appearance in ISO-14001 and is the only definition available: Element of an organization’s activities, process, or services that can interact with the environment. Note: A significant environmental aspect is an environmental aspect that has or can have a significant environmental impact. (ISO-14001, Clause-3.3). ii. Environmental Impact: Any change to the environment, whether adverse or beneficial, wholly or partially resulting from organization’s activities, products or services. (ISO-14001, Clause-3.4). Environmental Pollution and Acid Rain: Environmental pollution is the greatest hazard of industrialization. Acid Rain, a form of air pollution, currently a subject of great controversy because of the widespread environmental damage for which it has been blamed. It forms when oxides of sulphur and nitrogen combine with atmospheric moisture to yield sulphuric and nitric acids, which may then be carried long distances from their source before they are deposited by rain. The pollution may also take the form of snow or fog or be precipitated in dry forms. In fact, although the term “acid rain” has been in use for more than a century—it is derived from atmospheric studies that were made in the region of Manchester, England—the more accurate scientific term would be

“acid deposition”. The dry form of such precipitation is just as damaging to the environment as the liquid form.

A British Antarctic expedition team observed the size of the ozone hole over the Antarctic sky during October spring period between 1977-1984 and found 40% depletion of ozone as compared to the 1960 base line as observed by the previous teams of Antarctic expedition. The results published in “nature” during 1985 stunned the world. On the contrary, the arctic ozone hole is different and more stable! Observations revealed only a 5-10% depletion of arctic winter ozone layer. This is explained by the fact that the arctic stratosphere warms up faster in winter as compared to the Antarctic stratosphere. This avoids winter cloud and ice crystal formation in the arctic stratosphere necessary for ozone depletion. However, in 1988-89, the arctic winter was unusual in being coldest in 25 years and resembled the Antarctic winter, and found much larger depletion of ozone

Israel is the first country to ban MSW Dumping. 2. Secured dump sites are not fully secure: They are not Earth quake resistant, The liners may get ruptured by uneven sinking of earth and by slow brittling of liners by loss of plasticizers. 3. Burial grounds are getting exhausted: Cities have grown and encircled all Burial grounds which were outside cities. Hazardous waste management includes a wide range of areas: 1. Industrial waste: Covered under Hazardous Waste Management Rules. 2. Municipal solid waste (MSW): Governed by Municipal Waste management Rules. There are Supreme Court interventions in this area, 3. Plastic waste: a very special case of all solid wastes: Governed by Recycled Plastics Manufacture and usage Rules, 1999, 4. Hazardous domestic and commercial wastes: These include Electronic waste, Bulbs and Tube lights, Battery, Oils and Greases, Paints & Solvents covered under different Rules, 5. Biomedical waste: Covered under Biomedical Waste management Rules, 6. Waste Electrical Electronic Equipments (WEEE) Guidelines: Being issued, 7. Battery Waste (Management and Handling) Rules, 2003: Covers only lead acid batteries, 8. Battery waste other than Lead acid batteries: Being included in Municipal waste. The key factor of management of all these wastes is “Segregation at Source” What is a hazardous waste? A Legal Definition: Definition of hazardous waste as given in the hwmh-rules-2000: A. Waste substances which are generated in the process indicated in col-2 of schedule-1 and consists of wholly or partly of the waste substances referred to in col-3 of the same schedule. B. Waste substances which consists wholly or partly of substances indicated in schedule-2, unless the conc. Of the substances is less than the limit indicated in the same schedule. C. Waste substances indicated by character in part-a, list-a, and b of schedule-3 applicable only to rule-12, 13 and 14 unless they do not possess any of the hazardous characteristics in part-b of the same schedule.

A generic definition: Hazardous waste may be defined as a product or by-product that has no value and its disposal is a hazard. Nature’s own definition: Anything not produced by nature and/or not compatible in quantity and/or quality with nature’s first law of “No ultimate waste” and Natur’s handling capacity is a hazardous waste Status of hazardous waste generation and management in India: 1. No reliable data on hazardous waste generation and management in india. 2. Rough estimates indicate 7.23 million tones of hazardous waste generated annually. 3. 4-major hazardous waste generating states: Andhra Pradesh, Gujarat, Maharashtra, and Tamil nadu. 4. CPCB has identified 12,584 units in 354 districts of 21-states generating hazardous waste. 5. General form of hazardous waste is sludge containing heavy metals, highly alkaline, acidic wastes, wastes from paint, dyes and organic manufacturing units. Ecological disasters resulting from indiscriminate disposal of hazardous wastes: 1. Large scale mortality of fish life in aquatic streams and lakes often reported in india, 2. Phyto toxicity due to heavy metal contamination in soil. 3. Ground water pollution and soil fertility degradation due to indiscriminate disposal of hazardous wastes. 4. Health effects on human population and animals due to water pollution. 5. Health hazards on lungs & internal organs due to air pollution Basic Two Technological Principles of All Waste Management: 1st Principle: Catch Wastes at source in Segregated and most concentrated forms. 2nd Principle: Establish individual specific treatment systems for recovery of reusable products from all waste collected at source. Some very common examples of waste management: 1. Heavy metal waste in Effluent aqueous waste: All heavy metals if collected at source in concentrated form (See 1st Principle), then they can be selectively precipitated and recovered for recycling. The technologies are based on pH

Solid Hazardous wastes by Embedding and encasing: Many common solid hazardous wastes like Asbestos, asbestos sheets, silica gel, alumina, ion exchange resin and so on are best managed by simply blending in concrete in suitable proportions and using for non-building works like cement grills, bricks for boundary wall, tree protection, garden benches and so on. 3. Tube lights and CFL lamps contain 2-3 mg of mercury vapour: Use bulb eater to adsorbed mercury on to active carbon and recovery mercury. This is detailed later. 4. Waste glass wool and mineral wool: Glass wool and mineral wool are made by fusion and spinning of glass and rock. So you can melt waste glass wool and mineral wool back to glass and rock and dispose off! Industrial hazardous waste segregation and treatment at source: In-house stream segregation: this segregation at source in general applies to all in industries, households, commercial establishments, hotels and hospitals. Not much is done in this basic need for segregation and treatment at source. This is basic to handling and management of hazardous wastes at all levels.

36 Copyright: HAMSAGARS A case on Industrial Eco-Park: The Kalundborg industrial park is located in Denmark. This industrial park is special because companies reuse each others' waste (which then becomes by-products). For example, the Energy E2 Asnæs Power Station produces gypsum as a by product of the electricity generation process; this gypsum becomes a resource for the BPB Gyproc A/S which produces plasterboards. This is one example of a system inspired by the biospheretechno-sphere metaphor: in ecosystems, the waste from one organism is used as inputs to other organisms; in industrial systems, waste from a company is used as a resource by others. Project work: Develop possible Industrial Eco-Parks based on 5-Industrial wastes in India. Example in India, Fly ash is now extensively used in blending cement and in Fly ash Brick making Eco-Systems are very sensitive interdependent balanced systems: Chirapunji once worlds highest rainfall area became scant in rain as a result of cutting down trees. In China, school children were asked to kill sparrows with Rubber band stone ejector and get paid for each sparrow to prevent grains being eaten by sparrows. Result, there was a surge of insects that the sparrows ate and these insects brought heavy destruction of food grains. There are numerous cases of this kind. Project work: Search website for “Silent spring” the best selling book of Rachel Carson in 1962 and prepare a report on the delicate balance of Ecosystem. Industrial Ecology examines societal issues and their relationship with both technical systems and the environment. Through this holistic view , IE recognizes that solving problems must involve understanding the connections that exist between these systems, various aspects cannot be viewed in isolation. Often changes in one part of the overall system can propagate and cause changes in another part. Thus, you can only understand a problem if you look at its parts in relation to the whole. Based on this framework, Industrial Ecology looks at environmental issues with a systems thinking approach. Industrial Eco-System Engineering: Engineering is designing and implementing a system. Industrial Eco-System Engineering deals with integrated management of the following three Factors: i. ii. iii.

This calls for “Green Technologies” phasing out of Non-Renewable Resources and involving use of Renewable resources, with Sustainable development allowing for regeneration of Renewable Resources being consumed and Recycling of all NonRenewable Resources used.. Goals of Industrial Ecology: The primary goal of industrial ecology is to promote sustainable development at the global, regional, and local levels. Sustainable development has been defined by the United Nations World Commission on Environment and Development as “meeting the needs of the present generation without sacrificing the needs of future generations. Key principles inherent to sustainable development include: i. ii. iii.
The sustainable use of resources, Preserving ecological and human health (e.g. the maintenance of the structure and function of ecosystems), The promotion of environmental equity (both inter-generational and intersocietal).
Challenges to Industrial Eco Engineering: Following are the some main challenges: i. ii.

iv. v.
The challenge of reversing Global warming requires Industrial Ecological Engineering and even after numerous UN-Efforts very little has been achieved, Reversing Depletion of water resources requires Rain water harvesting and recharging under ground water. But the Ground water is dropping at alarming rate of about 3 feet per year, Ozone Layer depletion requires elimination of all OD-Compounds but even the OD-Substitutes are not fully immune to OD. So we still do not know how to eliminate OD. On the Energy front use of renewable resources of energy namely Solar, Wind, Hydro, Geothermal have not made significant progress, No alternate low cost Energy resource still exists to substitute Fossil fuel energy although Hydrogen and Hydrogen Fusion technologies are possible successors

Fly ash: Fly ash has well-known two applications as under:
i. Fly ash for blending in Cement: This is now widely used in Cement plants and special Fly ash carrying lorry tankers are in use. A typical Fly ash Tanker is shown. These are also useful in carrying all free flowing powders and grains: ii. Fly ash is also used in Brick making and many steel plants have set up fly ash brick making plants. Bricks are made by blending Fly ash with about 10% cement and 5% water proofing compound and cast in to bricks. The process is very similar to Clay brick making.

40 Copyright: HAMSAGARS The major policy initiatives taken to encourage private/foreign direct investment to tap energy from renewable energy sources, include provision of fiscal and financial incentives under a wide range of programs being implemented by the Ministry of Non Conventional Energy Sources, and simplification of procedures for private investment, including foreign direct investment in renewable energy projects. There is also a package of incentives for renewable energy projects. These include: i. ii. iii.
iv.
Concessional / nil customs duty on import of projects , equipment and components related to renewable energy; 100% depreciation allowed in the first year of investment for the installation of renewable energy projects (except for small hydro projects); liberalized foreign investment approval regime to facilitate foreign investment and transfer of technology through joint ventures. Proposal for up to 100% foreign equity participation in a joint venture qualify for automatic approval; and Policy announcements by state governments/ SEB's for evacuation of power generated from renewable energy projects with facilities for wheeling, banking, third party sale and purchase of power by SEB's at remunerative prices.
The fiscal incentives provided for this purpose include 100 per cent depreciation in the first year of the installation of the project, exemption from excise duty and sales tax and concessional customs duty on the import of material, component and equipment used in renewable energy projects. In addition, the Government provides financial incentives, such as interest subsidy and capital subsidy from the Ministry and soft loans from Indian Renewable Energy Development Agency (IREDA) . Fourteen states have so far announced such policies in respect of various renewable energy sources. While coal continues to be primary source of energy since it is in abundant supply in India, there is an attempt to improve the energy derived from renewables including hydro. India has a large hydro-power potential and only a small part of it has been exploited. Similarly, a lot of work is going on in other renewable areas like bio-mass, and solar energy but they are yet to be deployed on a large scale. A three-fold strategy has been adopted by the Ministry of Non Conventional Energy Sources for promotion of renewable sources of energy: i. ii.
Providing budgetary support for demonstration projects and rural energy systems. Extending institutional finance from Indian Renewable Energy Development Agency (IREDA) and other financial institutions for commercially viable projects, with private sector participation; and external assistance from international and bilateral agencies.

Providing private investment through fiscal incentives , tax holidays , depreciation allowance , facilities for wheeling and banking of power for the grid and remunerative returns for power fed into the grid.
Insofar as the protection of environment is concerned, the Ministry of Environment & Forests plays a pivotal role and administers the Environment Protection Act, 1980 and the Air (Prevention and Control of Pollution) Act, 1981. All power projects which are set up in the country require the approval of the Ministry of Environment & Forests. Power generation in India: i. ii. iii. iv. v. vi. vii. viii. ix. x.
The present installed capacity for power in the country is about 1,00,000 MW. Almost 71% of this is from thermal sources, About 24% is from hydro. Nuclear accounts for about 2.9% The rest is derived from wind. It has been estimated that in order to meet the demand for power by 2012, an additional 1,00,000 MW of installed capacity would be required. This implies that the power sector has to grow by approximately 10,000 MW every year for the next 10 years. This involves a huge quantum of investments which is estimated to be US$ 200 billion. This includes investments to be made for matching transmission and distribution. The short term goals aim to fulfill the minimum energy needs of the entire population and reach the remote and isolated corners of the country at the earliest.
Energy Conservation efforts in India: i. ii.
iii. iv. v. vi. vii. viii.
The following programmes have been undertaken for promoting energy conservation in India: Energy audit at selected Thermal Power Stations (TPS) to assess the controllable losses, measures to improve efficiency and reduction of secondary fuel oil consumption. Research project to mitigate GHG emissions from selected power sectors in selected Asian countries. Renovation & Modernization at selected TPS. Life extension assessment studies at selected TPS. Adoption of clean coal technology at selected TPS. Setting up of coal washeries at coal mines. Adoption of fluidized bed technology for boilers and super critical parameters for some selected TPS.
Energy conservation and efficiency is an important thrust area of the government and the Energy Conservation Bill was introduced in Parliament. The Bill, at present, is under discussion and once it is passed by Parliament, the Bureau of Energy Efficiency (BEE) would come into being. This would be responsible for energy audits, labeling, setting of Licensed for use only in Programs conducted by Faculty from HAMSAGARS

These include an accent on fuel efficiency; training programs in the transport sector; modernization of boilers; replacement of furnaces and equipment, and standardization of irrigation pump sets. These activities are the concern of the Petroleum Conservation Research Association (PCRA) and of oil companies. R&D Work on Energy sector in India: Research & Development in cleaner fossil fuels is an ongoing activity and a number of options regarding clean coal technologies are being explored. They include the Fluidized Bed Combustion, Circulating Fluidized Bed Combustion, Pressurized Fluidized Bed Combustion Combined Cycle, and Integrated Gasification Combined Cycle. In the renewable sector also, a number of new technologies are being explored in the following areas: i. ii. iii. iv. v. vi. vii. viii. ix. x. xi. xii.
Solar energy Energy from Urban and Industrial Waste Biogas Technology Biogas combustion based power generation Biomass Gasification technology Small Hydro Power Wind power technology Fuel cell technology Hydrogen energy Alternative fuel for surface transportation Ocean energy Geo-thermal energy etc.
R&D Achievements in Energy Sector in India: R&D is of crucial importance for technology development and application of renewable energy sources. Some of the key achievements of R&D have been the development of a large number of high-efficiency smokeless wood stove designs; new and low-cost designs of family-size biogas plants using ferrocement material and for leafy bio-mass feedstock; development and application of single crystal solar photo-voltaic technology, including polysilicon, ingots, wafers, cells and modules; low-grade solar thermal technologies including selective coating for solar thermal collectors and alternative designs of solar cookers; small-scale biomass gasifiers run on wood and agro-residues as fuel; optimized cogeneration based on high-pressure boilers; development of high-rate biomethanation processes; adaptation and indigenisation of wind turbines, including indigenous development of rotor blades and intelligent power controller; development of polymer electrolyte membrane and phosphoric acid fuel cell technology; and metal hydrides for storage of hydrogen.

Control of CO2 Emissions in India: The problem of C02 emissions is a major concern to the Indian energy sector where coal accounts for over 60% of total energy resources used. In order to minimize C02 emissions, efforts are underway to improve efficiency levels in the generation and use of energy. In addition, renewable energy technologies and afforestation measures to increase the "carbon sink" function are being promoted. Coal India Limited (CIL), a holding company of seven coal producing companies, coordinates the implementation of sustainable development programs in the Indian Coal Sector. There is a special focus on ensuring conservation of coal sources during exploitation and use, and conserving energy in the production and transportation of coal. Private Sector Participation in Power generation: The Government of India had announced a policy in 1991 which allowed private sector participation in power generation and distribution schemes. Since 1991, generation has been thrown up to private including foreign investment. Twenty five power projects (wholly) and one power project (partially) with an installed capacity of 5489.75 MW has already been commissioned in the private sector and another about 5200 MW are under construction. The private sector is likely to contribute about 40% of the generating capacity of 1,00,000MW required to be added during 2002-12. The Government of India has also enacted the Electricity Laws Amendment Act, 1998 to promote private sector investments in transmission. The Government has also issued guidelines for private sector participation in January, 2000. Most large and Medium Industries now have their own Captive Power Plants (CPP) and are also musing energy conservation techniques like Heat recovery and efficiency and Pollution control techniques. An overview of India's Renewable Energy Sources: The importance of increasing the use of renewable energy sources was recognized in India in the early 1970s. During the past quarter century, a significant effort has gone into the development, trial and induction of a variety of renewable energy technologies for use in different sectors. The country has today among the world’s largest programs for renewable energy. The activities cover all major renewable energy sources of interest to us, such as biogas, biomass, solar energy, wind energy, small hydro-power and other emerging technologies. Several renewable energy systems and products are now commercially available, and are also economically viable in comparison to fossil fuels. The Ministry of Non-Conventional Energy Sources (MNES) created in 1992 is the nodal agency of the Government of India for all matters relating to non-conventional/renewable energy. It undertakes policy making, planning, promotion and coordination functions relating to all aspects of renewable energy, including fiscal and financial incentives, creation of industrial capacity, promotion of demonstration and commercial programs, R&D and technology development, intellectual property protection, human resources development and international relations.

Indian Power sector services to other countries: India is now also in a position to offer its goods, technical expertise and services in this sector, particularly to developing countries. Technical guidance and help has been provided to many developing countries for the construction of bio-gas plants. Products, which are being exported include solar photo-voltaic systems, wind turbine equipment, selectively coated sheets for thermal applications and solar cookers. Indian made wind turbine and wind turbine components have been exported to Europe, Australia and Sri Lanka. Indian designs of gasifiers have attracted countries like Switzerland, Indonesia and the USA. A Swiss company has installed Indian designs of gasifier based decentralized power generation units in Switzerland. Aforestation efforts in India: Since a large part of energy needs in the rural economy is through collection of firewood this leads to deforestation. The reduction of tree cover is a serious problem though several programmes have been launched by the government towards afforestation. Problems of deforestation are primarily on two counts. While the first is the lack of access to commercial forms of energy, the second is the sheer lack of purchasing power. The government has been trying to mitigate the problems by giving subsidized kerosene to people subsisting below the poverty line. There is compulsory compensatory reforestation for power projects and other projects which cause any forest degradation. Government is taking several steps on the pollution control front and there are strict pollution control norms for all energy generation projects. The Economic growth and Environmental issues and Industrial Ecology: Any effort towards economic growth comes in conflict with Environmental protection. High economic growth entails high consumption of natural resources and environmental pollution and contradicts the concept of sustained development. Economic planning for sustained development should include the costs of maintaining environmental resources and ecological services. In other words our planning budget shall include economic growth budget along with ecological sustenance budget. This is planning and budgeting for sustained development. As mentioned earlier, the concept of sustained development came in to focus with report of the Brundtland commission-“Our Common Future (1987) which stated that our economic growth has to be environmentally sustainable and there is no economic growth without ecological costs. The national accounting and budgeting should reflect both economy and environment. Industrial Ecology is a concept where every industry complies fully with the fundamental laws of Nature where there is no end product or waste product. Ultimate answer lies in ensuring zero discharge of solid, liquid and gases pollutants and ensuring recycling everything at the micro and macro level exactly as nature does it so efficiently and effectively.

What is Ecology? We have learnt about Ecology in both Part-1 and Part-2. Here we give more formal definitions on Ecology: Oxford Dictionary Definition: i. ii.
The branch of biology dealing with the relations of organisms to one another and to their physical surroundings (Environment). Human ecology is the study of the interaction of people with their environment.
Definition in Microsoft Encarta: Ecology is the branch of biology that deals with organisms' relations to one another and to the physical environment in which they live; (the study of) such relations as they pertain to a particular habitat or a particular species. Oxford Talking Dictionary: The study of the relationship of plants and animals to their physical and biological environment. The physical environment includes light and heat or solar radiation, moisture, wind, oxygen, carbon dioxide, nutrients in soil,

Revisit our Graphic Presentation on Nature, Environment, Ecosystem and Biosystem all in one: Nature: Earth, water, Atmosphere, solar system, and Life system.
Ecosystem: Environment: Surroundings in relation to life system
Life system in relation to surroundings
Biosphere: Nature that inhabits Life system
Nature, Environment, Ecosystem and the Biosphere.
What is Ecological Balance? The Ecological balance is the closely inter related, dependent and harmonious balance amongst Biosystem and Environment in the Ecosystem. Rachel Carson’s best seller of 1962 “Silent Spring” had for the first time an immense awakening of the hard reality of the Ecological Balance. She pointed out that resulting from extensive use of pesticides, birds and beneficial insects have been destroyed and the spring time no more brings us the sweet songs of birds and pollinating insects but the roar of helicopters spraying pesticides! To prevent destruction of food grains by sparrows, the Chinese provided incentives for children to kill sparrows and get paid, the result: insect population multiplied immensely and destroyed all of food crops! They had to reintroduce sparrows to keep insect population under control! So the Ecological Balance is so delicate, a small change will lead to a chain reaction and destroy the delicate balance. Biodiversity: Term for variety or diversity within the biological world. In its widest sense, biodiversity is virtually synonymous with “Life on Earth”. The word was coined in 1985 and during the 1990s has become very widely used in the popular media and in government and scientific circles. It has become customary, partly as a matter of convenience, to consider biodiversity at three hierarchical levels that have special significance in human affairs:

i. ii. iii.
49
Gene Biodiversity: Different genetic variations of a species in a given region, Species Biodiversity:: Different species of life in the same region, Ecosystem Biodiversity: Different Ecosystems co-existing in the same region.
It is important, however, to recognize that these are just some of the ways in which biodiversity may be assessed, and that there is no precise definition of what the word means and thus no agreement on how biodiversity can best be measured. (Microsoft Encarta, 2003). Habitat: The natural environment characteristically occupied by a particular organism; an area distinguished by the set of organisms, which occupy it. Also such areas collectively called Habitat. (Oxford Talking Dictionary). Habitat is the place in the environment where a species lives: Air, water and land are the main habitats for all kinds of life. Specific habitats include sea, lakes, rivers, soil, swamps, forests, mountains and so on. Biological clocks or Biorhythms: All Natural time rhythms like breeding of animals and flowering of plants in springtime linked to season, the menstrual cycle linked to the lunar cycle, precise time of flowering of specific flowers (There is one or more flower varieties flowering every hour of the day! and so on there are numerous rhythms that constitute the Biological clocks or Biorhythms. All Biorhythms are, said to be, linked to some cosmic cycles. Our sleepwake cycle is linked to the diurnal cycle of day and night.

The Competitive Exclusion Principle: In community ecology, the competitive exclusion principle, sometimes referred to as Gause's Law of competitive exclusion or just Gause's Law, is a theory which states that two species competing for the same resources, cannot stably coexist if other ecological factors are constant. Either of the two competitors will always overcome the other which leads to either the extinction of one of the competitors or an evolutionary or behavioural shift towards a different ecological niche. As a consequence, competing related species often evolve distinguishing characteristics in areas in which they coexist. This aids in mate recognition, thus maintaining each species' superiority in exploiting slightly different ecological niches. Experimental basis for Competitive Exclusion: Russian ecologist Georgii Frantsevich Gause formulated the law of competitive exclusion based on laboratory competition experiments using two species of Paramecium, the Paramecium aurelia and Paramecium caudatum. Following a lag phase, the Paramecium aurelia was consistently able to drive the other to extinction. The conditions were to add fresh water everyday and input a constant flow of food. However, Gause was able to let the Paramecium caudatum survive by driving differently the environmental parameters (food, water). This explains why the Gause law is valid only if the ecological factors are constant. Also used were two species of yeast, Saccharomyces cerevisiae and Schizosaccharomyces kefir. S. kefir consistently out-competed S. cerevisiae by producing a higher concentration of ethyl alcohol. Mutualisms & Symbosis: i.
ii.
Mutalism: Some populations interact in a mutalistic manner in communities, one form of cooperation. In a mutalistic situation, two populations benefit equally. One example of such a mutalistic cooperation involves two insects, ants and aphids. Aphids feed on trees by sucking sugary tree sap out of the tree's phloem. But aphids are not very neat, But not all of the sap reaches your car. Some species of ants take advantage of this smaller insect by effectively domesticating the aphids. The ants directs the aphids from plant to plant, then milk them for the sap like a group of dairy cows. This is Community relationship between species. Symbiosis: Two species who have a symbiotic relationship have a close, long-term association. symbiosis can be mutalism, but there are two other forms of symbiotic relationships. Commensalism describes a cooperation between two species that is beneficial to only one species. In such a relationship, the other species is not harmed. The third form of symbiosis is parasitism,

The Producers: The Plants are Producers of primary food from solar energy, water and minerals and Nutrients. ii. The Primary Consumers: The herbivores are the consumers of this primary plant food and produce enriched food for carnivores iii. The Secondary Consumers: Carnivores are consumers of secondary food. iv. The Decomposers: Bacteria and fungi are the decomposers of the dead plant and animal remains producing primary nutrients for plants completing the food chain or the food cycle.

Food Pyramid: i.
ii.
The overall Food cycle looks simple and elegant but behind this simplicity lies a very complex system of infinite Food pyramids and Food Webs. Following is an example of a food pyramid An Example of Food pyramid: Grass and vegetation at the base of a Food pyramid produce primary food consumed by rabbits snakes consume rabbits Vultures consume snakes. There are pyramids within pyramids. For example, snakes live on rats and frogs, frogs live on insects, insects live on many types of food and so on.

Note that a Food Pyramid is a vertically placed food chain where the number increases down the pyramid with highest number at the base and least number at the top of the pyramid. (Source: ww.explorelearning.com).
Note in the following example of Food Pyramid, rabbits are food to snakes and snakes in turn are food to Vultures. The number of species in the lowest level of any food pyramid e.g. Rabbits have to be largest for survival and the ones in the next food pyramid namely Snakes have to be less than Rabbits and finally last top species in the Food Pyramid i.e.
the Vultures have to be least in number. An Example of Food pyramid What is a Food Web? The Food chain looks pretty simple and straight forward. However, there are no simple specific Food chains in the Ecosystem. In fact the use of the term “Chain” is a misnomer as there are no chins and dead end processes in Nature (see 1.1 The Fundamental Laws of nature). Ecosystem is a complex web of cycles. The Food web is a part of this system of cyclic webs in the Ecosystem as depicted in the next slide. Food webs are essentially composed of a number of discrete food pyramids. A Food pyramid is nothing but a vertically placed food chain in which the number increases down the pyramid with highest number at the base of pyramid and lowest at the top.

Tropic and Atrophic: i. ii.
iii.
Atrophic: refers to an organism requiring only simple inorganic compounds for nutrition. Plants are Atrophic. Trophic: refers to or pertaining to the feeding habits of, and the food relationship between, different types of organisms in the food cycle. Animals are Trophic. Trophic level: refers to any of a hierarchy of levels of an ecosystem, each consisting of organisms sharing the same function in the food chain and the same relationship to the primary producers. (All definitions from Oxford Talking Dictionary).
The Trophic Pyramids-Pyramids of Energy, Biomass and Numbers: i.
ii.
iii. iv.
Energy dissipation in Food Chain: Food Conversion efficiencies are always much less than 100%. At each link in a food chain, a substantial portion of the sun's energy - originally trapped by a photosynthesizing Atrophic Plants - is dissipated back to the environment (ultimately as heat). Trophic level: Trophic level is the level in Food Pyramid where the population exists. Thus it follows that the total amount of energy stored in the bodies of a given population is dependent on its Trophic Level. For example, the total amount of energy in a population of toads must necessarily be far less than that in the insects on which they feed. Toads are in higher Trophic Level than insects. The insects, in turn, have only a fraction of the energy stored in the plants on which they feed. Pyramid of energy: This decrease in the total available energy at each higher Trophic level is called the pyramid of energy.
Biomass and Pyramid Number: i.
ii.
Biomass: is the weight of the body mass of a given species (number of species multiplied by the average body mass). Biomass Pyramid shows the Biomass relationship at Trophic levels. Pyramid of Numbers: is the relative population at each Trophic level. These are Shown in Next slide.
(Source:http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/F/FoodChains.html# The_Pyramid_of_Numbers): Energy Balance in the Ecosystem: Net production is only a fraction of gross production because the organisms must expend energy to stay alive. Note that the difference between gross and net production is greater for animals than for the producers - reflecting their greater activity.

Much of the energy stored in net production was lost to the system by a. Decay, b. Being carried downstream
ii.
Note the substantial losses in net production as energy passes from one Trophic level to the next.
iii.
The ratio of net production at one level to net production at the next higher level is called the conversion efficiency. Here it varied from 17% from producers to primary consumers (1478/8833) to 4.5% from primary to secondary consumers (67/1478). From similar studies in other ecosystems, we can take 10% as the average conversion efficiency from producers to primary consumers.

The Ecological Pyramid (Source: www.archi.org). Net Primary Production (NPP): It is the Photosynthetic production of plants minus what they use for their own life process. It is the GNP of the Ecosystem. NPP is measured in terms of Pg/yr where 1 Pg.(Pico gram) = 10^15 g. Total Terrestrial NPP=132 Pg/Yr. of which 39% is lost to human exploitation. (Source: dieoff.org). Ecological services: Constitute the life sustaining and Ecosystem balancing services in the ecosystem. Maintenance of right proportion of Oxygen and Carbon dioxide is essential for maintenance of plant and animal life on earth. Maintenance of dissolved oxygen in water is essential to marine life. Increased pollutants affect these balances destroying life on earth and water. Following are the main Ecological services: i. ii. iii. iv.
Resources: Air, water food, and minerals are the primary services in the Ecosystem, Eco-cycles: The Fundamental Laws of Nature. Regulatory services: Maintenance of temperature, pollination, climate control, ozone layer maintenance are regulatory services in the Ecosystem. Scavenging services: Pigs, vultures, ducks, dung beetles are some of the common examples of garbage scavengers of nature.

The Economic growth and Environmental issues and Industrial Ecology: Revisited: Any effort towards economic growth comes in conflict with Environmental protection. High economic growth entails high consumption of natural resources and environmental pollution and contradicts the concept of sustained development. Economic planning for sustained development should include the costs of maintaining environmental resources and ecological services. In other words our planning budget shall include economic growth budget along with ecological sustenance budget. This is planning and budgeting for sustained development. As mentioned earlier, the concept of sustained development came in to focus with report of the Brundtland commission-“Our Common Future (1987) which stated that our economic growth has to be environmentally sustainable and there is no economic growth without ecological costs. The national accounting and budgeting should reflect both economy and environment. Industrial Ecology is a concept where every industry complies fully with the fundamental laws of Nature where there is no end product or waste product. Ultimate answer lies in ensuring zero discharge of solid, liquid and gases pollutants and ensuring recycling everything at the micro and macro level exactly as nature does it so efficiently and effectively. Population, Poverty, Health, Education, Environment and Economic growth: These are at the very core of civilization and global issues. “Poverty is the greatest pollutant” was the Indian stand at the Global meets on Pollution. Health and Education are at the core of poverty elimination. India is endowed with rich resources. India is a very large market. There are very few markets in the world of the size of India and China. As for intellectual ability is concerned “Indians are one of the most intelligent people on earth!” Why do we have a growth rate of just 6-7% against 10% of China? One of the main problems not well recognized so far is that we have too many leaders and very few followers. We are a country of leaders without followers at every stage. What is the reason and what we can do about it? This takes us to Attitude and Culture.

Now check where you are? What is Culture? Culture is a complex phenomenon. In its simplest form it is the individual and collective behaviour and actions in a society. Scientifically culture is built around Attitudes, Beliefs and Value system in a society. Culture is the fertile delta of the confluence of three behavioural rivers in Attitude, Beliefs and value system. Diagrammatically one can depict Culture as given below:
ATTITUDES

Ecotechnology: is an applied science that seeks to fulfill human needs while causing minimal ecological disrupution, by harnessing and subtly manipulating natural forces to leverage their beneficial effects. Integration: Ecotechnology integrates two complementary fields of study: the 'ecology of technics' and the 'technics of ecology,' requiring a substantial understanding of the structures and processes of ecosystems and societies. Sustainable Engineering: All sustainable engineering that can reduce damage to ecosystems, adopt ecology as a fundamental basis, and ensure an orientation of precaution in the implementation of the conservation of biodiversity and sustainable development may be considered as forms of eco-technology.

Ecological Succession Primary and Secondary: i.
ii.
iii. iv.
Ecological succession: Is a fundamental concept in ecology, refers to more-or-less predictable and orderly changes in the composition or structure of an ecological community. Beginning of Succession: Succession may be initiated either by formation of new, unoccupied habitat (e.g., a lava flow or a severe landslide) or by some form of disturbance (e.g. fire, severe wind throw, logging) of an existing community. Primary succession: Is Succession that begins in areas where no habitation is initially present. Secondary succession: Is Succession that begins in areas where habitation is already present which gets replaced by another species.
Autogenic succession: Autogenic succession can be brought by changes in the soil caused by the organisms there. These changes include accumulation of organic matter in litter or humic layer, alteration of soil nutrients, change in pH of soil by plants growing there. The structure of the plants themselves can also alter the community. For example, when larger species like trees mature, they produce shade on to the developing forest floor that tends to exclude light-requiring species. Shade-tolerant species will invade the area.

65
Allogenic Succession: Allogenic Successions are caused by external environmental influences and not by the vegetation. For example soil changes due to erosion, leaching or the deposition of silt and clays can alter the nutrient content and water relationships in the ecosystems. Animals also play an important role in allogenic changes as they are pollinators, seed dispersers and herbivores. They can also increase nutrient content of the soil in certain areas, or shift soil about (as termites, ants, and moles do) creating patches in the habitat. This may create regeneration sites that favor certain species. Climatic factors in Succession: Climatic factors may be very important, but on a much longer time-scale than any other. Changes in temperature and rainfall patterns will promote changes in communities. As the climate warmed at the end of each ice age, great successional changes took place. The tundra vegetation and bare glacial till deposits underwent succession to mixed deciduous forest. The greenhouse effect resulting in increase in temperature is likely to bring profound Allogenic changes in the next century. Geological and climatic catastrophes such as volcanic eruptions, earthquakes, avalanches, meteors, floods, fires, and high wind also bring Allogenic changes. Clement's theory of succession/Mechanisms of succession: F.E. Clement (1916) developed a descriptive theory of succession and advanced it as a general ecological concept. His theory of succession had a powerful influence on ecological thought. Clement's concept is usually termed . According to Clement, succession is a process involving several phases: i. ii. iii. iv.
v. vi.
Nudation: Succession begins with the development of a bare site, called Nudation (disturbance). Migration: It refers to arrival of propagules (Propagating species). Ecesis: It involves establishment and initial growth of vegetation. Competition: As vegetation became well established, grows, and spreads, various species began to compete for space, light and nutrients. This phase is called competition. Reaction: During this phase autogenic changes affect the habitat resulting in replacement of one plant community by another. Stabilization: Reaction phase leads to development of a climax community.

66 Copyright: HAMSAGARS Seral Community: A seral community is an intermediate stage found in an ecosystem advancing towards its climax community. In many cases more than one seral stage evolves until climax conditions are attained. A prisere is a collection of seres making up the development of an area from non-vegetated surfaces to a climax community. Depending on the substratum and climate, a seral community can be one of the following: i. ii. iii. iv. v.
Hydrosere: Community in water (Hyacinth) Lithosere: Community on rock (Algae and Fungus) Psammosere: Community on sand (Grass) Xerosere: Community in dry area (Cactus) Halosere: Community in saline body (marsh-weed)
The climax concept and Climax community: i.
ii.
The Climax: According to classical ecological theory, succession stops when the sere has arrived at an equilibrium or steady state with the physical and biotic environment. At this point the community is stable and self-replication. Barring major disturbances, it will persist indefinitely. This end point of succession is called climax. The Climax Community: The final or stable community in a sere is the climax community or climatic vegetation. It is selfperpetuating and in equilibrium with the physical habitat. There in no net annual accumulation of organic matter in a climax community mostly. The annual production and important is balanced in such a community.
Agenda-21 for the 21st Century: Agenda 21, the Rio Declaration on Environment and Development, and the Statement of principles for the Sustainable Management of Forests during 21st Century were adopted by more than 178 Governments at the United Nations Conference on Environment and Development (UNCED) held in Rio de Janerio, Brazil, 3 to 14 June 1992.
