  4. Case Study of Remedy for Plastic Waste Ahmed Khan, was a plastic sack manufacturer in Bangalore found an ideal solution to the ever - increasing problem of accumulating plastic waste. He was 57 years old, and has been producing plastic sacks for 20 years....

  5. Note - Bitumen is a black viscous mixture of hydrocarbons obtained naturally or as a residue from petroleum distillation. It is used for road surfacing and roofing. He later realized (about 8 years ago)...that plastic waste was a real problem. Polyblend, a fine powder of recycled modified plastic, was developed then by his company. This mixture is mixed with the bitumen that is used to lay roads. But why??

  6. Note Polyblend is a mixture of two or more polymers, especially of man-made fibers or recycled plastic. He collaborated with R.V.College of engineering and the Bangalore city corporation, and proved that blends of polyblend and bitumen, when used to lay roads, enhanced bitumens water repellent properties...when used to lay roads, and helped to increase road life by a factor of 3.

  7. Logic behind this??? . The raw material for creating Polyblend is any plastic film waste. Initially, rag pickers used to get RS. 0.40 per kg of plastic waste. offers Rs.6. So, using his technique, by the year Khan now 2002, more than 40 kms of road in Bangalore has already been laid. At this rate, Khan will soon be running short of plastic waste in Bangalore, to produce polyblend.

  8. Other sources of hazardous wastes, Hospitals -generate hazardous wastes that contain disinfectants and other harmful chemicals and also pathogenic micro organisms.(use of incinerators is crucial to disposal of hospital waste.) Incinerators is an apparatus for burning waste material, especially industrial waste, at high temperatures until it is reduced to ash. Irreparable computers and other electronic goods are known as electronic wastes (e - wastes) .These are buried in land fills or incinerated.

  9. Over half of the e - wastes generated in the developed world are exported to developing countries, mainly to China, India and Pakistan, where metals like copper, iron, silicon, nickel and gold are recovered during recycling process. Recycling in developing countries involves manual participation unlike developed countries which have specifically built facilities for recycling of e- wastes. . Manual participation exposes workers to toxic substances present in e wastes. Recycling is the only solution for the treatment of e - wastes, if carried in an environment-friendly manner. Recycling is the process of converting waste materials into new materials and objects.
