Often times food waste such as supermarket waste or leftovers still contains a mix of organics and packaging. This contamination makes it more difficult to reuse resources in both fractions. Food waste is commonly used to generate biogas in a digester. If inorganic material enters the digester, it will eventually reduce the effectivity of the process. The Organic Liquefying Press separates packaging from food waste and additionally improves its biogas potential.
To separate the food waste, it is fed at the top of the Organic Liquefying Press from from a conveyor. Then, the material is first pre-pressed and then separated under high pressure. The resulting fractions are the plastic and organic fractions.
