Abstract

Low Density Poly Ethylene (LPDE) plastic waste has no sale value, buried in a landfill. The plastic itself cannot be broken down by microorganisms in the soil, so that people destroy it through incineration. Incineration plastics produce NOx, COx, SOx, particulates, dioxins, furans, and smoke, which can increase air pollution with acid rain and global warming. The purpose of this research is to solve this plastic waste so that it can be reprocessed into more valuable fuel through the pyrolysis process. The pyrolysis equipment used is a reactor unit made of stainless steel and equipped with an insulator made from rock wall. The primary tar reservoir is between the reactor outlet channel and the condenser inlet. The condenser unit is made of a steel shell and a spiral-shaped copper tube where the condensed product is a secondary tar product. The pyrolysis process produces 3 products, namely solid residue (char), liquid product (tar), and gas products. The number of products analyzed in this study only char and tar in the pyrolysis of LDPE plastic waste was analyzed based on temperature variations, namely 200°C, 250°C, and 300°C. The process in the reactor using natural zeolite catalysts. The results obtained are the highest quantity of char 10.80% and the primary tar 81.19% by processing in a reactor with a temperature of 200°C without the use of a catalyst, the secondary tar product 91.01% by processing in a reactor temperature of 300°C using a catalyst. The highest yield of fuel oil was 94.80%, and the lowest remaining solids residue was 5.2% in the reactor process using a catalyst with a temperature of 300°C for 6 hours.
