Plastic waste to liquid fuel
In the geographic centre of India, Alko Zadgaonkar has developed a way to convert plastic waste material into liquid hydrocarbons. Her method involves regulated anaerobic heating of a mixture of mixed plastic waste (90 per cent) and coal (10 per cent) in the presence of a catalyst.
In a trial facility, the technique is being used to convert some 10 tonnes of plastic waste into about 10,000 litres of hydrocarbons per day. The next step is scaling up the plant to take 25 tonnes of waste / day and generating electricity from the 15 per cent gaseous output of the reaction. The Indian Oil Corporation has recommended use of Zadgaonkar liquid fuels for running agriculture pumps and boilers and as input feed for petrochemical refineries.
