The composition of fuel production per litre from polyethylene waste via pyrolysis was determined through thermal degradation. Compositions of fuels from high density polyethylene/low density polyethylene (HDPE/LDPE) pyrolysis were naphta, gasoline, and active carbon as residues. The pyrolysis process was carried out at 450-621°C without any catalyst and quantitative analysis method was conducted by using GC-MS. The product of 5 kg pyrolysis HDPE are 3.25 litres of naphta; 0.85 litre of gasoline; 0.325 litre of diesel fuel; and 18.06 grams of active carbon. Then the product of 5 kg pyrolysis LDPE are 0.5 litres of naphta; 2.9 litres of gasoline; 0,1 litre of diesel fuel; and 19 grams of active carbon.
