Approximately nine million tons of plastic wastes are disposed of in the ocean each year, and only nine percent of plastic wastes are being recycled while the rest are improperly disposed of – such as littering, dumping of hazardous and radioactive wastes on the ground, open burning, and even through mixing different types of waste in a bag thrown in the landfill. One of the plastic wastes that are being disposed of in the sanitary landfill are single-used plastic wastes such as Low - Density Polyethylene (LDPE) and High - Density Polyethylene (HDPE) plastics. Since plastic was the usual waste generated in the households, commercial, and even industrial, using it as a material to create another product has been considered. This study was conducted to convert nonprinted single-use plastic waste, from Salaan Sanitary Landfill, into trash bin by using used cooking oil for melting and moulding. These three treatments were used to determine the right rationing for moulding, Treatment No. 1 using 100 mL used oil: 70 grams HDPE: 30 grams LDPE, Treatment No. 2 using 200 mL used oil: 70 grams HDPE: 30 grams LDPE, and Treatment No. 3 using 300 mL used oil: 70 grams HDPE: 30 grams LDPE. Among the three treatments, Treatment No. 1 and Treatment No. 2 showed great results in terms of mechanical testing but, it was not suitable for manual moulding since they have high viscosity leaving Treatment No. 3 to be used since it was less viscous. As per the various testings conducted, the outcome for the Treatment No. 3 resulted positive appearing closer in data with the commercially available polypropylene trash bins, therefore the research product was made from this. The third treatment was considered viable since the product was smooth in mixture and could be moulded easily. As a result, despite being moulded manually, the research product can stand equally with the storebought product which underwent injection moulding.
