BANGALORE (Reuters Life!) - An Indian company has found a novel use for the heaps of ecologically unsound plastic that litter Bangalore: it's turning it into roads.

K.K. Plastic Waste Management, run by brothers Ahmed and Rasool Khan, collects thousand of tonnes of waste plastic from garbage bins across India's IT hub through a network of municipal workers, rag pickers and their own employees.

The plastic is then shredded and mixed with asphalt to form a compound called polymerized bitumen. When used in paving, the brothers say it withstands monsoons and daily wear and tear better than traditional methods, and also reduces pot holes.

Scientists agree. Professor C.E.G. Justo, a Bangalore-based highways and roads experts, said the process of mixing plastic waste in road construction enhanced the performance of the road.

"It (waste plastic) gets into some of the voids of the bituminous mix and makes it more resistant to deterioration under wet weather conditions," Justo told Reuters Television.

Ahmed Khan, the managing director of the firm, says the idea struck about a decade ago when various organizations started anti-plastic campaigns.

"Every day there is 10,000 tonnes of waste plastic and it would all go to landfills, how much of that can you do? There, it does not degenerate or bio-degrade and ultimately it will be a problem so this is the best solution," he said.

The remaining garbage, separated from the non bio-degradable plastic, can be turned into compost, Khan added.   Continued...
