The Pune Municipal Corporation is planning to make better use of the waste plastics. The civic body is reportedly planning to have roads constructed using a mixture of polymer glue and tar that is made from shredded plastic waste. As per reports, there are plans to construct around 25 roads in various parts of the city making use of this technique. Funds will be allocated for the purpose.
As per reports, the standing committee of the civic body will take a call on setting up a plant for making a plastic mix for roads. A tie-up with two firms will be inked. These include a chemical and an environmental company. They will collect plastic that will then be converted into a mixture, which will be added to the tar. Shredded plastic between 2.36 mm and 600 microns is reportedly used to construct the road. The shredded plastic is obtained by chemically treating the plastic waste generated from urban areas, which includes plastic bags and packing material. As per reports, it is heated at high temperature and then converted into a powder form. It is then added into a hot mix of tar.
The civic body has planned the expansion of this project after the success of a pilot project done in 2016-2017. The Central Pollution Control Board (CPCB) has already cleared the use of this technology for road construction, from the point of view of pollution. The use of plastic helps increase the life span of the road by around two years. It also helps in saving money as maintenance costs reduce. Overall, nearly Rs 30,000 per sq km can be saved using this technique.
