Now plastic waste could be burnt and distilled to avail lubricating products like petrol. A preliminary version of pyrolysis plant is developed by a man in Perinjanam panchayat. Mr V.S. Sreejith is the man behind the idea. Srijith worked in solid waste management for several years and now he is director of the science centre in Kodungallur. All this is a part of his attempt to process non-biodegradable waste in low cost and pollution-free technology.
“Petroleum is converted to plastic products by heating it at a particular temperature. In the pyrolysis plant of the prototype which we have developed, a reversal of polymerization happens,” said Mr.Sreejith. “The plant is at present burnt using LPG for display, but the biogas from organic waste will be utilised for the purpose when the civic body puts the technology to use to processing plastic. Out of 10 kg of plastic, 9 litres and 600 ml of petroleum can be extracted using this technology,” he added.

The demonstration of the plant was held at Perinjanam community hall on Tuesday. Gas is generated by the burnt plastics in the plant. Using water, the long-chain hydrocarbons in it are condensed and converted into petroleum in a liquid state. The small chain hydrocarbons remain as a gas which can be used as a substitute for LPG or biogas.
Distilled sample of petrol will be handed over to petrochemical companies for quality test. The extracted petroleum from plastic can be further distilled into petrol and other lubricating products like wax and turpentine. The activated carbon in the burner can be reused for making paints and water purifiers.

“If the plastic waste is provided free of cost, the only expense will be for the labour. The civic body would soon obtain an NOC from the Pollution Control Board and start such plants at different areas in the panchayat,” said Perinjanam panchayat president K.K. Sachith.
