admin The word is out in the market ‘go green to save the world’. Efforts are being made to counter environmental problems like waste-management, global warming, greenhouse effect in the last few decades and there are several ‘green’ products available within the shops now. Textile sector has also been a witness to several changes in the demands of consumers concerning green products. In order to make the product design optimum, to improve product manufacturability, to resolve the problems occurring in product’s remanufacturing, the concept of green production evaluation system is important. The aim of evaluation system is to ensure that the textile and clothing production saves energy, reduces emission and consumption to realize efficient usage of resources.
Green production evaluation plays a contributory role to understand synchronized growth between textile and clothing industry and therefore the ecosystem. The primary step is to analyse the assembly links and after this the evaluation index system is put up. The index system looks thoroughly into six level of textile manufacturing that are use of water and energy, followed by how the waste water, gas and materials are treated, then comes controlling the unsafe or harmful materials to human health, the type of technology being used i.e. how advanced it is, product and style idea, package consumption and dealing environment of workshops.

This is a primary callout. The first step in evaluation is consumption of water and energy. The textile sector uses tons of water, astechnical processes including bleaching, boiling, dyeing, printing, finishing, washing of wool, reeling of cocoon, etc. consume gallons of water. In addition to the present, textile plant conditioners and therefore the staff working in the plant also require usage of water in large quantities. Water consumption can be calculated by ton per ten thousand.
The chemical fibre, cotton textile and printing and dyeing plants also are major energy consumption industries. In some developing countries like India, per unit energy consumption is 40 percent higher than that of international advanced level. It is to be noted that a serious improvement in textile plant management may result in reduction of waste of resources, avoid serious environment pollution and cut high cost. A proper assessment of water and energy consumption can actually lower production cost, save resource and reduce environment press.
The next step is evaluation of the waste water, gas and materials. The waste water coming from textile is full of natural impurities, organic matter of fat and amylum. It has been established that the printing and dyeing waste water contains organic matter of dyes, detergent, amylum, cellulose, ligin and inorganic matter of alkali, sulfide and various salts. The waste gas includes sulfur dioxide, fumes and dust. This is generated after burning of coal and poses serious threat to the environment. The material wastage involves offal short fibre from chemical and mechanical action, wasted yarn and waste materials during spinning and weaving production, loss of cloth during cutting process. These waste materials are treated by burning or burying which pollute environment seriously. Some textile mills utilize waste pieces of cloth by producing a replacement fabric from the pieces.
While the pandemic is the most urgent threat facing us this year, the climate crisis represents the greatest challenge to the future of humanity – and also vast opportunities for those disruptors and scalers that deliver closed loop, clean economy solutions.
The business community hasn’t always been an ally of the planet, but it would have a significant role to play in the next half century of environmental action – including developing and deploying solutions, on a global scale, to problems they quite often had a hand in creating.
