Conversion of plastic waste to fuel oil using pyrolysis process

The development of this project is based on the purpose of converting plastic waste into fuel oil. The study is focusing on the design and fabrication of a plastic waste oil converter as an effort in finding environment-friendly means of waste recycling. It is an alternative solution to increasing problem of waste disposal by converting waste plastics into a resource. Pyrolysis process was the basis in the design and fabrication of the equipment. The conversions of Polypropylene (PP), Low Density Polyethylene (LDPE) and High Density Polyethylene (HDPE) into Plastic Waste Oil (PWO) are the key element of this design and development project. The converter consists of a filler tube, stove, working table, condensing rod, beaker, stop valve, condensing chamber, cooling outlet and intake. The filler tube attached to a mechanism of condensing unit, which collect the amount of PWO in a beaker. The stop valves functioned to allow the cooling medium entering the condensing system. Hence, plastic waste which evaporated travel through a condensing chamber, which made to turn the vapour into PWO. The filler tube is made of stainless steel with holding capacity of 500g/batch of plastic waste. The equipment tested for five trials using 500g of Polypropylene (PP), Low Density Polyethylene (LDPE) and High Density Polyethylene (HDPE) plastics per trial. With the aid of this equipment, it can optimize the amount of PWO produced due to its arrangement. Recommendations also discussed in order to increase the performance of plastic waste converter.
