NOVELTY - Solid waste recovery involves pretreating raw material as waste to be treated to achieve an amount of water less than 17%, and a diameter not exceeding 10 mm material. The different fractions of waste to be treated, are separated, where the biomass fraction on remaining fractions of plastics, glass, and metals are sanitized and dried. The rest of polypropylene plastic is separated, where the biomass fraction is treated through catalytic depolymerization. The ferrous and non-ferrous metals are separated with respect to the fraction of plastics.    USE - Method for recovering solid waste such as urban, forest residues, pruning, agricultural origin, certain industrial wastes, biomass, plastics and mineral and vegetable oils for producing synthetic diesel fuel for use in diesel engines.    ADVANTAGE - The method prolongs lifespan of landfills, and facilitates comprehensive treatment and recovery of waste to obtain synthetic diesel fuel with a high calorific value and high uniformity. The obtained synthetic diesel fuel replaces fossil fuels, and reduces gas emissions and pollutants.    DETAILED DESCRIPTION - Solid waste recovery involves pretreating raw material as waste to be treated to achieve an amount of water less than 17%, and a diameter not exceeding 10 mm material. The different fractions of waste to be treated, are separated, where the biomass fraction on remaining fractions of plastics, glass, and metals are sanitized and dried. The rest of polypropylene plastic is separated, where the biomass fraction is treated through catalytic depolymerization. The ferrous and non-ferrous metals are separated with respect to the fraction of plastics. The resulting fractions including polypropylene waste, is heated at 280 degrees C, where the hydrocarbon fraction is depolymerized for forming synthetic diesel fuel. The formed synthetic diesel fuel is desulfurized after separation and condensation, and then collected in liquid form. The resulting water and leachate from both pretreatment processes are treated and purified.
