Abstract

The increase in the use of plastic results in an increase and accumulation of the volume of plastic waste which causes environmental problems, because plastic is an inorganic material that is very difficult to decompose in nature. This research was conducted to utilize Polyethylene Terephthalate (PETE) plastic waste into liquid fuel by pyrolysis method using a catalyst in order to increase the yield of liquid products and the quality of the liquid fuel produced. The research method is carried out by making a simple reactor to obtain liquid fuel, after the product is produced, the yield is calculated, and the density, viscosity, and calorific value are tested. The results of this study prove that the use of bentonite clay catalyst produces a higher yield of about 4.1% to 6.7% than the use of activated carbon catalyst with a yield of 21.74% and a heating value ranging from 10572 to 10860 cal/ g. Likewise, the density and viscosity of the product are still classified as meeting the quality standards of commercial fuel oil (BBM).

Abstract

Plastic, which is originated from petrolum, is possible to turn it to alternative fuel. Moreover in 2008, the estimated amount of midden in Indonesia reached 38.5 million tons per year with the largest compositions are organic waste (58%), waste plastics (14%), waste paper (9%) and wood waste (4%) (Ministry of Environment, 2008). Meanwhile in Depok City, the amount of waste which goes to Depok City’s landfill waste is 350-400 tonnes / day (Head of Technical Unit Landscape Depok City Sanitation Department, 2012). From the data, above, can be confirmed using plastic waste as an alternative fuel can be superior because plastic waste is the raw material which is cheap, easily processed, and can reduce environmental pollution. The processing of plastic waste into fuel conversion is done using a plastic waste machine with a continuous system, the working principle of heating at high temperature. Tests which are conducted in this study is to test the octane rating by bomb calorie meter, test anylizer gas emissions, and test octane gas chromatography. Plastic waste fuel, which is the outcome from plastic waste conversion machine with continuous system, can be used as fuel for vehicles, it is because the plastic oil calorific value 10 519 cal / g equivalent calorific value premium. This research is expected to address the scarcity of fossil fuels, and increasing public awareness of using alternative fuel, especially plastic waste fuel.
