From fryer to fuel
After frying frites, bitterballen, churros or arancini, many people don’t think twice about disposing of used cooking oil. Yet one litre of waste oil can contaminate one million litres of water, according to the European Commission. At Cargill’s facility in the port of Ghent, Belgium, used cooking oil and other residual oils and fats are treated as raw materials, cleaned and converted into biodiesel for trucks and ships. This puts circularity into practice on an industrial scale at one of Europe’s largest facilities of its kind. Since production began, Ghent’s biodiesel is estimated to have reduced greenhouse gas emissions by 1,188,000 tonnes compared with fossil diesel, equivalent to taking about 550,000 cars off the road for a year.
