Abstract—This paper presents the study and experimentation of fuel oil production by conventional slow pyrolysis using plastic waste from a municipal landfill. The different proportions of liquid fuel produced from landfill plastic obtained by non-catalyst conventional slow pyrolysis were studied. The landfill plastic was collected from Warinchamrap municipality landfill, in Thailand. The investigation of recycling of model and waste products based on PP, LDPE, HDPE, and mixed plastic were examined using conventional slow pyrolysis and distillation methods. The experimental results show that the reactivity of conventional slow pyrolysis and distillation can be controlled by temperature, time, and energy. The various types of plastic found in the municipal landfill were converted into differing amounts of liquid fuel. PP was converted into 80% liquid fuel, LDPE 73% to liquid fuel, HDPE to 70% liquid fuel, and mixed plastic to 46% liquid fuel. The distillation liquid fuel included high-quality liquid fuels. The liquid fuels derived from the waste plastic found in the municipal landfill was similar to petroleum diesel oil.
