b) Write about the remedy found for the efficient use of plastic waste by Ahmed khan of Bangalore.

Answer 1

A web of molecular monomers linked together to make macromolecules of unlimited use throughout human society is made of plastics.

Complete answer:
First we should know about plastics to answer this question. In medicine and health care, the advantages of plastics are especially apparent. Plastics are durable, cost-effective, need less resources to manufacture than substitute materials, like glass or metal, and can be produced with several distinct characteristics.

a) Colourful polystyrene and plastic bags used to cover food is considered an environmental hazard because plastic is non-biodegradable and the process of recycling is very expensive and requires manual intervention, thereby exposing staff to harmful pollutants created during the recycling process.

b) The solution discovered by Ahmed Khan of Bangalore for the effective use of plastic waste was made of Polyblend, a delicate powder of recycled transformed plastic. This combination is blended with bitumen which is used for road setting. In cooperation with R.V. Ahmed Khan, College of Engineering and Bangalore City Corporation, showed that when it is used to lay roads, blends of polyblend and bitumen improved the water-repellent abilities of the bitumen and helped improve road life through a factor of 3.

Note: It is time to reconsider the existing plastics processing and disposal management process and step towards a model that takes into account the whole life-cycle of these plentiful, important materials. Ultimately, dumping of plastics in landfills is harmful and reduces land services that are fit for other higher public value purposes.
