IIT Guwahati students make Diesel from Plastic waste.

Researchers from IIT Guwahati have converted packaging plastic waste into plastic-derived oil (PDO), which has similar characters of diesel.Low- and high-density polyethylene (LDPE, HDPE) and polypropylene are commonly used as packaging materials and end up in the waste stream. According to Pollution Control Board report, almost 15,000 tonnes of plastics waste is generated per day in India every year. Did you know the Interesting facts about distance?

The researchers collected the waste from houses, cleaned and segregated them according to the resin identification code.Using a semi-batch reactor, the wastes were heated for several hours at 300-400 degree Celsius. “Heating at very high temperatures in inert conditions caused the plastic to convert into wax, so we chose this particular temperature range in which the plastic turned to plastic-derived oil and stayed in its oil state,” said the Institute member.

“More experiments need to be carried out to get a trade-off between the quality of the oil and the environmental pollution caused by the pyrolysis process. We are working on this and hope to create an ideal operating condition which can provide high-quality oil with less pollution,” says, Assistant Professor, IIT Guwahati.

They studied the properties of the new plastic derived oil. One of the oil samples from polypropylene showed a high research octane number of approximately 92. Octane number indicates the quality of the gasoline range fuel. Premium petrol has research octane number of 98 to 100, which is an absolute number.

The oil also had high calorific value and low viscosity. Calorific value denotes the amount of heat generated when a unit amount of sample was burnt with oxygen supply. The new oil had a calorific value greater than 45 MJ per kilogram. “We are yet to carry out engine tests. Once tested, these oils can soon find application in transport and industrial sectors,” said the professor.
