  • Are waste cooking oils a valuable source of raw materials?
  • Conclusions Waste cooking oils (WCOs) represent a valuable source of raw materials with a wide range of applications, from energy to lubricants or soaps.
  • How much does purified oil cost?
  • It is possible to estimate a consumption of 1.583 kWh to produce 25 tons of purified oil, which corresponds to an overall energetic cost of approximately 7 € (euros) per ton of purified oil, based on the average energy prices in Europe for non-household consumers (0.11 €/kWh) .
  • How is edible oil produced?
  • Conventionally, edible oil is produced by extraction with an organic solvent alone or by screw pressing prior to solvent extraction.
  • How many metric tons of used vegetable oils are produced a year?
  • The yearly overall production of used vegetable oils exceeds 190 million metric tons, with the European Union (EU) contributing about 1 million tons/year [7, 8]. A proper handling of WCOs is mandatory in many countries (and currently the subject of political discussion in others) [9, 10, 11].
  • How much does a waste oil recycling machine cost?
  • In fact, the simplicity of such treatment, which is mainly aimed at removing volatile compounds and water from crude WCOs, allowed the commercial production of machines for small-scale WCO recycling. Nowadays, it is possible to buy a waste oil recycling machine for less than 15,000 USD .
  • How is crude oil processed?
  • The general process applied to the raw material can be resumed as follows: the crude oil is subject to a gross filtration, aimed to remove solid contaminants, and then heated under vacuum. Through reduced pressure distillation, the crude oil is purified from the volatile fraction, resulting in a regenerate oleic product.
