Andhra College students convert waste plastic into crude oil
Vijayawada (Andhra Pradesh): Nowadays, any mention of plastic is synonymous with pollution. But with the right approach, plastic can create wonders.
Working on this approach, three M.Sc students of KBN college in Vijaywada have made a remarkable breakthrough in converting waste plastics into crude oil that is widely used in industrial production.
Every day, thousands of tons of plastic waste is disposed of. Some of these are single-use plastics while some others are durable plastic lids and pipes.
High-density plastic is made by the polymerization of Vinyl Chloride. Bottle caps and pipes are made from this material.
By throwing away bottle caps and broken pipes, we are giving rise to pollution. Instead, these three MSc students have found a way to produce petrol by recycling these products.
Siva, Pawan Kumar and Harish Kumar, students of MSc Organic Chemistry, have succeeded in producing crude oil from plastic wastes. They have showcased the working model in their college tech fest. They have produced crude oil from the vapours emitted by burning PVC plastic waste.
Speaking to ETV Bharat, Shiva said, "We can extract crude oil from plastic. This can be done in two ways, small scale method and large scale method. When we heat the Polyvinyl Chloride, we get crude oil in the form of vapours. Later, when the crude oil undergoes pyrolysis process, we get petrol."
Pyrolysis of this crude oil produces petrol and diesel. The students also claimed that they produce 100 gm of crude oil from 2 kg of plastic waste.
The students also said that disposed plastic cups and pipes can be used to produce petrol and diesel. By combining their intellect with guidance from professors, they are converting waste plastics into crude oil.
Dr Krishnaveni, Head of Chemistry Department, said that students have worked really hard for this project.
"Our project is on extracting crude oil from plastic. In this project, we used Polyvinyl Chloride plastic and with the process of pyrolysis at 200-400 degree centigrade, we extracted crude oil. From this, using fractional distillation, this crude oil can be converted into different components like petrol or diesel. By this process, we can get petrol at Rs 30-40 per litre. We are preparing this from the plastic waste out of PVC pipes. We have tried different types of plastics but the output from PVC pipes was good," said Krishnaveni.
