your on-line toolbox for efficient textile production

Thank you for downloading this document from www.e-textile.org, the on-line toolbox for efficient textile production. E-textile.org provides a wide range of useful, informative and sector-specific features, such as benchmarks, success stories, tips for action, regulations, links and contacts. Key features of e-textile are three tools, namely

•

e-learning: an on-line course providing background information on efficient textile production,

•

e-efficiency: a management tool for identifying improvement options and increase a companies overall performance,

•

e-solutions: a database containing descriptions of well over 200 efficiency measures.

1.1.5. CLEANER PRODUCTION – A FUTURE PROSPECT? The increasing size of the population, the increasing material per capita demand, and the material and energy inefficiency of industrial activities are affecting our environment at an alarming rate. Key environmental problems, such as deforestation, the increasing ozone hole, acidification, eutrophication, global warming, the rising sea level, urbanization and desertification are the result. Increasingly human and environmental health is in jeopardy. Assuming the above arguments as causing factors to the ongoing environmental quality deterioration, the following points can be made: LIKELY REASONS WHY ENTERPRISES, PRACTICING CLEANER PRODUCTION, DO BETTER ON THE SHARE MARKET RELATIVE TO THOSE NOT PRACTICING CLEANER PRODUCTION? - Higher product volume income for same material input costs - Less waste treatment costs - More pro-active management attitude (probably not only in environmental issues) - More critical employee attitude (not only towards environmental issues) - Better internal and external communication - Better public relations

•

Reducing the size of the population: This is a hot political issue in the context of development cooperation, income distribution, human rights, global trade, North – South division, etc. Although progress in terms of population growth reduction has been made in a number of countries, the fact remains that the global population growth figure has never before been so high with a doubling of the present 6 billion people expected in a little over 40 years. However, the influence on this particular phenomenon of the practicing engineer or scientist is limited.

•

Reducing the material per capita demand: Also this meets with political sensitivity in the sense that the ‘North’ enjoys a high per capita consumption with a relatively small population size, while the ‘South’ combines a low per capita consumption with a relatively high population size. Moreover, the growth rate of both population and per capita demand is highest in the ‘South’. Therefore, progress in this area will at most be slow. However, on the positive side, the automatism of the ‘more is better’ concept is slowly loosing ground. Moreover, the need for reducing per capita consumption is also visible in the consumption of certain compounds, for example CFC’s, lead in fuel, specific anti-microbial paints, etc. In this area quite some progress has been.

•

Reducing industrial energy and material inefficiency: This area, covered under the broad topic of Cleaner Production, is where significant progress has been and is being made. Redesigning of industrial processes, waste separation, waste reuse, recycling, recovery, inclusion of costs for expenditures to process products after their useful life in the purchase price, green labeling, zero emission production, etc. are topics that have passed the conceptual stage and are, to a varying extent, being practiced.

For now, reducing per capita waste production, the realm of Cleaner Production, is one of the very few areas which can potentially at least partly counterbalance the imminent problems related to human and environmental health. An additional advantage is the potential for economic benefits for those willing to see. Therefore, Cleaner Production has more than a future. Wide-scale introduction of the concepts and practice of Cleaner Production is presently one of the few options available to bring a halt to the ongoing deterioration of the human and environmental health conditions.
