Abstract: A process includes continuous steps and batch steps for recycling waste oil, fuel or antifreeze. The continuous steps include determining the volume of waste; pumping waste toward a distillation vessel; mixing waste with heated waste, and while flowing the waste into the distillation vessel performing steps of: maintaining a vacuum; heating the waste; returning a first portion of heated waste to the distillation vessel and a second-portion to mix with the waste feed; sending gaseous vapors to a condenser; returning some condensed liquid to the distillation vessel; and delivering condensed liquid as a product. The batch steps include: stopping waste flow into the distillation vessel; reducing pressure; heating the waste; returning the heated waste to the distillation vessel; condensing gaseous vapors; returning some condensed effluent to the distillation vessel; delivering some condensed effluent as a first product; and delivering heated waste as a second product.
