Remo-Frit, a potato processing factory in Beveren Belgium, uses potato peels coming from the potato processing to produce biogas.
By digesting 3.300 m³ of potato peels and sludge the factory produces up to more than 14.000 m³ of biogas per day. This biogas is used to run an enormous volume of refrigerators to keep the company’s potato products such as French fries chilled before delivery. This is a very nice example of using a by-product from a food processing plant as a source of alternative energy which is paying for electricity that would otherwise be bought from the grid.
