Mathematical Approach for Selection of Waste Plastic Oil – Diesel Blends

The challenges of waste management and increasing fuel crisis can be addressed simultaneously with the production of fuel from plastic wastes. Global warming and waste management policies have forced for the use of alternative fuels on engines. The production of fuel from plastic wastes will indeed tackle the environmental pollution problem of waste plastic management in the land fills. Plastics being derived from petrochemical source has higher amount of hydrocarbon which yield oil with high calorific value. Engine tests have been carried out using neat Waste Plastic Oil and blends of Waste Plastic Oil in proportions of 25%, 50%, and 75% with diesel as fuel. Combinatorial Mathematics Based Approach (CMBA) has been adapted to choose the optimum blend for superior performance of the engine. Engine performance combustion and emission characteristics under different loads for different test fuels are discussed. The results of CMBA and experimental tests showed that WPO25 is the optimum blend.
