There is something comforting knowing that somewhere in Spain our old cooking oil, long after it cooked your calamari, is running someone’s car.
Increasing oil prices and Middle East tensions make biodiesel fuel increasingly important as it is so environmentally friendly, renewable and above all cheap. And when converting old cooking oil it makes even more economic sense.
For some years it has been a geeks’ paradise with “home brewing” DIY biodiesel kits costing a few hundred Euros, and as long as they could find sufficient used chip fat they had a fuel for their cars costing a few cents per litre.
More recently commercial operators have entered the market and will not only produce biodiesel from waste oil but also deal with unwanted by-products previously a problem for home producers. For Cantueso, this means our old sunflower oil is now converted into fuel and we have a supply of soaps, hand and floor cleaners all from the glycerin that is the main by-product of the process and someone somewhere drives down the Autovia on Cantueso biodiesel 🙂
