Introduction Reality is, the earth is a planet with dirty seas and rivers, denuded forests and smog covered cities, home of seven billion people and thousands of species of biota which are on the brink of a cataclysm. The global environment change that human kind has brought about in the short span of may be a century, has gone its own interest and the well-being of other species inhabiting the planet. Whatever the views may be, the hard truth is, mankind is now living in a habitat with degraded environment and depleted resources. To improve his material wellbeing man has depleted the earth’s resources and degraded its environment. With the advent of science and technology he has begun to enjoy all amenities of life. His demand begins to increase. He has come across the need to establish the industry. Thus comes the industrial period and man has started depleting resources and degrading environment. The developed nations firstly practiced all kinds of industry but now they are much conscious of the social cost of primary industries which are nothing but most essential for life. Developed countries then deemed the developing country as the producer of primary goods. Thus developing nations begin to face industrialization but in exchange with big social cost. Although, in Bangladesh, industrialization goes with its small extent, the unplanned proliferation of industrial units and their encroachment on fertile agricultural land is a cause for concern. Wastes from these industries have polluted the environment in and around these establishments. Industrial wastes originate from various types of manufacturing and processing units. There are many ways of discharging these wastes, the easiest and the cheapest mode being dumping the untreated wastes on the land around the industrial unit producing these. This is the practice adopted in developing countries like Bangladesh disregarding its negative impact. But now the processes are being changed though in a little extent, by degrees, in discharging wastes. Basically there two types of wastes- solid and liquid. In most of the cases the solid wastes are recycled so it has not any major impact on the companies and that’s why our matter of concern is the liquid wastes (effluents) which have a long impact on the environment as well as on the company. Effluents are treated by a treatment plant named ETP (Effluent Treatment Plant). Some public and private companies now have ETP s for discharging their emitted effluents after treatment so that they cannot do any harm to the environment. The main among the polluting industries are: chemical manufacturing, plastic, cement, tannery industries, fertilizers, distilleries, textile weaving and dying, steel mills, paper pulp, pesticide, pharmaceuticals etc. For our observation on Waste Management Plant we have selected three different sectors: Tanneries, Textiles and Pharmaceuticals. Now some details about the whole matters.

Waste: Definition: The European Union defines waste as an object the holder discards, intends to discard or is required to discard is waste under the Waste Framework Directive. Once a substance or object has become waste, it will remain waste until it has been fully recovered and no longer poses a potential threat to the environment or to human health.

Classification of Waste: According to European Union classification of waste are as follows. From where our matter of concern is the industrial waste. This can be two types, solid and liquid. But in most of the cases the solid wastes are re-used in various ways that’s why it should be called residual not waste. But the liquid or effluents are so much harmful for the environment. So it needs to be treated.

Waste Management: Efficient waste management involves: considering the amount of waste being disposed of considering the type of waste being disposed of customizing a waste management solution taking both the amount and type of waste being disposed of into consideration. Industrial wastewater treatment covers the mechanisms and processes used to treat waters that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use. ETP stands for Effluent Treatment Plant. The factories which discharge toxic chemicals as effuenlt needs to setup ETP and ETP reduce the toxic chemicals from the water fully or maintain the normal water standards Effluent treatment plants (ETP) are broadly used in industries recently to treat the industrial wastewater.

The Economic Impact of Waste Management Plant on the Factories in Bangladesh: We have made our assignment in three segments. Three different sectors are in there. Tanneries, Textiles, and pharmaceuticals. Among them the tannery industries are most hazardous for the environment of Dhaka city. In our first segment we will explain the present condition of waste mismanagement in that industry.

Leather or Tanneries The tannery industry is the forth in earning foreign exchange, cause phenomenal environmental pollution to the soil, ecology and the human body. Of the 270 tanneries in the whole country 90 % are located in Hazaribagh, a densely populated residential area of Dhaka (WB 1993:128). Left units are in Chittagong, Jessore, Dhamray and Savar. According to a report of UN-FAO (1991), everyday the tannery units all over the country generate 8.47 million litter liquid wastes and 98 MT solid wastes of these Hazaribagh alone generate 7.70million liter liquid waste and 88 MT solid wastes. The treatment facility of waste management has not yet developed in tannery industries in Bangladesh. Only two industries in Bangladesh who have ETP. They are Apex and Bata located in Dhamray and Saver. But in Hazaribagh it’s not available yet.

Facts related to the Establishment of ETP: We were introduced a leading leather industry Bay Tanneries Ltd which is a bonded wear house of GOB. But they have not yet establish any types of waste management plant. But why? - “Installing individual treatment facility is an expensive venture.” Said N. Karim Biswas, Manager Admin, Bay Tanneries Ltd. According to him, there company would enlarge their business instead of setting up an ETP. By which they can get profit. Though GOB have taken some initiative to force the factories for setting up ETP in recent times, by the power of there association they can protect themselves from the GOB pressure. But the new comers of the industry are so much obliged to set up ETP for getting the registration. .

This toxic waste ultimately goes into the Buriganga River and to the adjacent crop fields.

Impact on employee: Bay Tannery has planned to set up ETP after their shifting to Saver. In which they are supposed to cut their labor wages, to maintain the high cost of ETP operation. But there is a possibility to a little portion of there labor force since the plant needs around three men to run.

Impact on Production: Effluent Treatment Plant (ETP) does not directly relate to the production but to the environment. So by setting up an ETP there is no possibility to increase production. Like this, in the case of tannery Industry, establishment of an ETP is not mandatory to attract foreign market. That’s why there has no major impact on production, but can reduce a little portion for the high cost of ETP establishment. Impact on Market : In the context of tannery industry the foreign buyers only want the quality of the product and they even not interested to know any other external factor. The factories are dependent on local market get low prices for their product. So they don’t go to maintain the high cost of establishment of effluent treatment plant on their factory. External Impact: The outsiders of tannery industry in Hazaribagh are being so much usual with that environment. The liquid tannery wastes carried by the City Corporations drains deposit in the low land, west of Hazaribagh. The solid wastes including tiny piece of leather, excess fat flesh hair, are piled up at roadsides in front the tanneries. Later, these are also thrown into the same low land and ultimately they make their own way to Buriganga River. Steps Taken by GOB : In recent days Bangladesh government have taken the environmental issue as an important concern. As a result, State Minister for Environment and Forests Mostafizur Rahman at a workshop in Dhaka has said that “setting up of any new factory will not be allowed without its own wastage recycling or effluent treatment plants (ETP)”. He also pointed out that a clean development mechanism (CDM) is necessary for Bangladesh, as many countries have adopted this eco-friendly industrialization technology. But what about the older? Setting up ETP is too costly for smaller industries to bear and only a few large groups can manage to afford it. The polluted air of that area is often causes diarrhea, stomach problems and nausea when it gets into human body.

Suggestions : Whatever was our suggestion, the govt. have done that already, that was transfer of tanneries from Hazaribagh. In Hazaribagh, there has not only the problem of capital but the land is also a big obstacle to establish ETP. Under the CDM (Clean Development Mechanism) project govt. should consider highly the tannery industry and have to inspire them for Carbon credit. In order to expedite installation of ETP the government should provide loans at lower interest rates to those kinds of industries.

Textile Industries: The textile and apparel industry in Bangladesh occupies a prominent position within the country’s industrial structure. It is the largest manufacturing sector, providing jobs for some 50% of the total industrial workforce and contributing 9.5% of the country’s GDP. Also, it accounts for almost 77% of total exports, making it Bangladesh’s leading foreign exchange earner. With such a high benefit the industry was not concern about the environment. But in recent times, its being mandatory for them to establish effluent treatment plants (ETP) on there factories to grasp the foreign market. Most of the export oriented textile industries in Bangladesh have established effluent treatment plant (ETP). According to Engineer Ahmed Ali, Vice President of BTMA. “Approximately 50 textile industries already have ETP, 25 industries are in construction and another 25 are planning to set up ETP”. For our observation we have visited a leading textile industry in our country, named PADMA Group of Textile, located at Bhulta, Narayangonj.

Reason for Establishing ETP: The company started its journey in 1985 and now it has been a leading industry in Bangladesh. It has been going with its ETP since 2002 and performing better than any other companies in our country. Social responsibility is the main reason for establishing an ETP. Though being very late, PADMA has established its ETP in line with that responsibility. PADMA emits 2 tones of toxic wastes daily. It concerned with the matter that if it would discharge all the effluents into the environment then it would be nothing but a great threat for the extinction of the species surrounded it. That was the primary reason for establishing ETP. According to their Managing Director, Engr. Ahmed Ali, “We did the plant from our social responsibility, because we need to survive first, then economic development will come automatically” Cost-benefit analysis: The effluents emitted from PADMA contain much alkaline types of materials, pH of which are 12-14. No doubt, it is much harmful for land. It damages the fertility of land. It is the ETP by which TDS (total dissolved solids) level of those elements in water can be reduced by 930 mg /L where the sustainable level is up to 2000mg /L. Soil contamination may occur from the disposal of sludge containing chromium. Chromium in its hexavalent form is toxic to humans. It may cause gastro-intestinal ulcer. Particulate matter containing lead

settles down on land contaminating the soil. Vegetables such as lettuce, potatoes, beans, and spinach may absorb lead from the soil. Lead is toxic to the nervous system and also cause anemia. Mercury may accumulate in body tissues and cause irreversible brain damage. These are the cost for society which may cost near about TK.1 billion per month. On the other hand, for PADMA it took only TK.1crore to establish its ETP and its monthly operating cost is only TK.2 lacks. So, how can we evaluate social benefit against company’s cost? The Process of ETP: There are three types of ETP- Biological, Bio-chemical and Chemical. PADMA is using the second category, which is not able to remove the Bacteria. The effluents emitted from PADMA contain much alkaline types of materials which are sodium hydroxide, potasiumhydroxide, etc. along with Chromium, Lead, Mercury, Chlor-alkali, and Sulfurdioxide. These hydroxide elements are severe bases pH of which are 12-14. For the purpose of treating this effluent, first Evaporation, then Crystallization of Salts and thereafter centrifuging is done to dewater the salt output from crystallizer. A combination of Industrial Evaporators like Falling film Evaporator, Forced Circulation Evaporator and the Industrial Dryers like Agitated Thin Film Dryer, Fluid Bed Dryer etc are used. Other auxiliary techniques such as centrifuging are also employed. Following is the plant design of the ETP of PADMA.

Structure of ETP Cost for the ETP: All sorts of investment for the ETP taken from their own fund. The initial set up cost was approximately TK1 crore. In which only machineries needed taka 70 lack. And other charges including purchase of land, charges for setting up etc meet the remaining. The companies per day production are 30.2 yards of clothes, and the emission of effluents per day is around 2 tons. To treat the effluents it has to count only 6/7 thousand taka per day. Impact on Employee: For a corporation, it is very easy to run an ETP, since it takes a little cost of their total cost. It does no matter while the social benefit is in concern. By observing the ETP of Padma Textile, we came to know that it has nearly to spend Tk15 thousand per month as wage for it needs only three men to run this. Is it too much? No. While our social benefit is highly profitable, in line with this. It facilitates those men to earn and support their family. It cannot be negligible in any way.

Impact on Production: ETP has an indirect relation to the production. Having ETP is a matter of social awareness. The company which considers the social benefit may certainly be considered as reliable to the masses. So it can certain have the global demand for its product. That has been happened to our concern PADMA group of Textile. Impact on Market: The companies’ main goal is to grasp the market. And to hold the foreign market, they have some mechanism, establishing ETP is one of them. By having ETP they can attract foreign buyers. Because their products demand the most reliability. That’s why a company can demand high prices against their product and thus they can make more profit by having than not having ETP. Suggestions: Though the export oriented large industries have established ETP, the small industries also need to do that. For that purpose GOB can provide loans with low interest rate under the supervision of Central Bank. That’s a matter the sector demands for a long time. Here also they can be attracted by the reward of Carbon Credit. Another steps GOB can take that is it can establish a central ETP for the small industries by which govt. itself can earn Carbon Credit.

The Pharmaceutical Industry Pharmaceuticals sector is one of the fastest growing sectors of the country's economy, which has the opportunity to grow further. Now it is the second largest sector after agriculture. Average growth rate of the sector is around 12.5 per cent. Local industries fulfill 97 per cent demand of the domestic market of about US $ 700 million. The local pharmaceutical companies are now exporting to 68 counties all over the world. Some leading pharmaceuticals companies are producing world-class products that are acceptable in the global market as quality product and the prices of the products are also competitive both in local and foreign markets. There are 239 registered pharmaceuticals industries, of which 161 are in operation. For our purpose, we were introduced one of the fastest growing pharmaceutical industries in Bangladesh named BEACON Pharmaceuticals Establishment Facts:.

The company is committed to its products, customers, management, employees, and other associates as well as to the environment that surrounds the company. The company has invested a huge amount of money on the state of the art Effluent Treatment Plant (ETP) in order to ensure clean and green atmosphere at the plant which ensures the safety and health of the employees and communities where they operate. Cost Benefit analysis: Cost-benefit analysis of having waste management plant and not having is a task to be concerned. Because it’s surely true that social benefit is much more valuable than the economic benefit. Not only that, but also establishing ETP can increase reliability of a farms product that’s why an industry can go forward. In the context of our concern, BEACON pharmaceuticals, they have invested only around 1.3crore taka for the ETP. But after having that their foreign market reliability have raised. So ultimately they are benefited by the waste management plant-ETP. Capacity of the ETP: The most advanced state of the art Effluent Treatment Plant (ETP) has a capacity of 2, 00,000 Lts / day. The effluents generated are treated at very high temperatures and are thermally oxidized and the treated effluents are utilized for the green belt development in the company premises. This is the first high capacity ETP in Bangladesh, which is commissioned with the full European regulatory requirements.They have introduced full sorts of ETP for waste water disposal and its management.

BEACON is treating its effluents by this plant.

Operation of The Plant:

The effluent from the ETP of BEACON consists of high organic content thereby making the effluent as high COD effluent. For the purpose of treating this effluent, Evaporation and Drying methods are used. A combination of Industrial Evaporators like Flash Evaporator, Falling film Evaporator, Forced Circulation Evaporator and the Industrial Dryers like Agitated Thin Film Dryer, Fluid Bed Dryer etc are used. Other auxiliary techniques such as centrifuging, filtration, incineration are also employed. But the condensate water generated after condensation of the vapors formed in evaporation process of this particular effluent tends to carry the volatile organic compounds thereby increasing the COD of condensate water and making it unfit for use/disposal. The COD of the condensate water can be brought down by rectification/ carbon treatment or aeration with a high pressure blower for prolonged periods.

Structure of Pharmaceuticals ETP Impact on labor, production and market: On the ETP of BEACON, there works only 5 men and there average salary is 5 thousand taka. It does not matter for such a large corporation. Moreover they are being reliable for having ETP which increase their products demand as well as production. That helps marketing strategy for the foreign market. Environmental Impact: BEACON has done well with its effluents. That is, the output liquid stream from the flashing chamber enters the multiple effects falling film evaporator for further concentration. And finally, whole of the effluent is converted into solid/sludge form so that

it can be disposed using various ways like land filling. So it doesn’t have any negative impact on the environment.

Concluding Remarks: More the earth is yielding to industrialization, more it is contributing to make itself as a habitat of hazard for all the flora and fauna live in it. But the international communities now are being much concerned about the matter. This community including developed and developing world is working well for saving all and sundry of the environment from a great catastrophe resulting from discharging toxic wastes from industrial units. For an instance, to reduce the emission of access carbon dioxide to the environment CDM offers carbon credit to the industries. The industries can be facilitated by the govt. in many ways. Governments make sure that they reduce the export duties of that industries which have well waste management plant.

Methodology For completing our task we have followed both primary and secondary method of collecting data. In method, we have had questionnaires. We had prepared different questionnaires for different sectors. Which we asked them to get our desired information. We studied on three different sectors- Tanneries, Textiles and Pharmaceuticals. Questions for the industries having ETP and not having ETP were different. That’s why two types of questions are shown below…. Having ETP
