This invention relates to a method and devices intended to pyrolysis and fractional distillation of plastic wastes to liquid fuel. Manually executed device for pyrolysis consists of metallic bucket with mineral wool internal insulation, while the furnace is made of refractory bricks. Within half an hour, temperature surpassing 400O, the steam of melted and vaporizing plastic is conveyed, by a cooper pipe, to container for condensation and conversion in the liquid fuel. By this process, tested several times for different weights of the waste, within 250-1,000 g, some 0.9 l of fuel is obtained from 1 kg of plastic. Given that it??s needed about 1 kWh of electric energy to get 1 l of fuel, that would present some 4-5 times cheaper fuel than at petrol stations!
