Physical and chemical methods of pollution control were always in the forefront because they were easy to understand, easy to control and were reproducible. Biodegrad ation, the real mechanism of nature of balancing the material, was always found to be incompletely understood, unpredictable and uncontrollable if we have to adapt it in the form of biological treatment methods. A better option then is to modify our materials, processes and products in such a way that we can rely upon the biodegradation in nature and recalcitrance, bioaccumulation problems are overcome. We are slowly changing our philosophy and are not merely targeting for clean-up or removal of pollutant but are aiming for prevention of pollution or facilitating biodegradation.
Manufacturing processes are rapidly changing and biodegradable products are fast replacing man-made, difficult to degrade products. After understanding the nature, its role, its sup eriority and by knowing the fact that biodegradation is the ultimate fate of any material that enters into environment, it was inevitable for us to change our psychology - industrial ecology - industrial ecosystem - industrial metabolism - going close to nature. Objectives then are to improve upon the method of production, searching for alternative raw materials, recycling, conversion to suitable forms of certain wastes, so that we do not add any material, waste in nature which nature cannot take care of.
Biodegradation mechanisms which occur in the soil, aquatic environment though slow are important for us as they do not involve any cost of treatment when it occurs naturally, and are safer and bring about complete degradation and not mere conversion . Hence incorporating biodegradability or aiming for biodegradability is an obvious approach while carrying out production of different items. The agricultural products, food products, commodities hereafter will carry a label of ecofriendly in most of th e countries. The trend is to spread to every material and product. The consumables, coal, oil, petrol, synthetic fibre, plastic which are polluting / non-biodegradable will be replaced slowly by the one which is non-polluting / biodegradable.
