Recycling Plastic waste

  1. Plastic waste to decontaminate water
  • Plastic waste can be used to develop  a low-cost magnetically responsive adsorbent material which can be used to remove an antibiotic cephalexin from water.
  • Upcycling polyethylene terephthalate (PET) waste into a magnetically responsive carbon nano-material by carbonization and activation of the PET char under controlled conditions and magnetic modification by a simple chemical precipitation route.
  • This technique of magnetic separation for spent adsorbent decreases the secondary pollution problems associated with the non-magneto active adsorbents.

   2.Plastic waste for rural road construction

  • Union Ministry of Rural Development has even recommended and issued guidelines to construct roads in rural areas of the plastic waste.
  • waste plastic, when added to hot aggregate will form a finecoat of plastic over the aggregate and such aggregate, when mixed with thebinder is found to give higher strength, higher resistance to water and betterperformance over a period of time.
  • Therefore, it is proposed that we may use waste plastic in the construction of Rural Roads.
  • Plastic Roads, are found to perform better compared to those constructed with conventional bitumen. Further it has been found that such roads were not subjected to stripping when come in contact with water.
