Economic impact of recycling cooking oil

In total in Spain some 850,000 t of vegetable oils are consumed. Olive oil is the most demanded with around 500,000 t, followed by sunflower oil with approximately 300,000 t.

The calories in 1 liter of oil are equivalent to approximately the energy of 0.92 liters of diesel. Bearing in mind that 1 A liter of diesel without tax costs in Spain about €0.65 ( March 2019). We can give a potential value of €0.60 to each liter of used oil. Obviously, that value has it once the impurities have been removed and processed to convert it into biodiesel.The purchase price of used oil will normally not exceed 5% of the potential value, being situated in the best cases in the 0.30 €/litre.

A family of 4 people consumes an average of 70 liters of oil per year and can recycle about 35 liters of used oil annually. Economically, this barely represents a potential income of €10. However, businesses such as restaurants can recover thousands of euros thanks to the recycling of used oil.

If we extrapolate to the entire population, we end up with potential business figures of 120 million euros for olive oil used and a saving in fuel imports of more than €200 million.This is thousands of direct and indirect jobs.In addition, by reducing energy imports, it improves the balance of payments and the financing capacity of the state.

Unfortunately, more than half of the oil consumed ends up in the sink. Instead of taking advantage of a resource that generates wealth, throwing away used oil ends up producing significant expenses in wastewater treatment.
