Polycrack

Relevance: Mains: G.S paper III: Science and technology

Why in news?

  • Indian Railways has commissioned the country’s first governmental waste to energy plant in Mancheswar Carriage Repair workshop at Bhubaneswar under the East Coast Railway zone.
  • The Waste to Energy Plant, having a capacity of 500 kilogram waste per day has been constructed in three months.

Key facts:

  • This Waste to Energy Plant, a patented technology called POLYCRACK, is first-of-its-kind in Indian Railways and fourth in India.
  • It is the world’s first patented heterogeneous catalytic process which converts multiple feedstocks into hydrocarbon liquid fuels, gas, carbon and water.
  • Polycrack plant can be fed with all types of plastic, petroleum sludge, un-segregated MSW (Municipal Solid Waste) with moisture up to 50 per cent, e-waste, automobile fluff, organic waste including bamboo, garden waste, etc., and jatropha fruit and palm bunch.

How the system can work?

  • The process is a closed-loop system and does not emit any hazardous pollutants into the atmosphere.
  • The combustible, non-condensed gases are re-used for providing energy to the entire system and thus, the only emission comes from the combustion of gaseous fuels.
  • The emissions from the combustion are found to be much less than prescribed environmental norms.
  • This process will produce energy in the form of Light Diesel Oil which is used to light furnaces.
