A Critical Appraisal of Techniques for Production of Liquid Fuel using Plastic Waste

Plastics are synthetic product produced from a wide range of polymers such as polyethylene, polyvinyl chloride, nylon etc. The property that makes it so ubiquitous to use is that it can be moulded to the desired shape and once is set can serve the desired purpose. Plastics are lightweight, inexpensive and durable materials, which find its use in a wide range of applications. The easy availability of plastics has led to its exploitation and careless use. This excessive usage caused the accumulation of huge amount of plastic waste into the environment. Plastics have a very high life in the environment and do not disintegrate through the natural process in the environment. So, the plastic disposal without any effective technique accumulates the waste into the environment certainly causing pollution. Researchers have shown that since plastics are a product of petroleum they have the efficiency to be used for fuel production which will solve the problem of plastic disposal and the rising fuel crisis. The review of past studies related to the fuel production from waste plastics, plastic waste disposal techniques, sources of alternative fuel and waste management technologies aims to find out the best technique for waste plastic disposal and a source of alternative fuel using the discarded plastics as feedstock. This would solve the problem of plastic waste disposal and fuel crisis in a
