Separate packaging from food waste

Royal Dutch Kusters Engineering - Organic Liquefying Press

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.

Benefits of separating food waste with the OLP

Unmatched resource extraction

The OLP brings unmatched resource extraction. Initial results suggest that around 30% more biogas can be recovered from MSW.

Modular design

With a robust design, remote monitoring and predictive maintenance, the OLP allows for low down time and increased efficiency of waste processing plants.

Speeds up digestion process of organic material

The cylinder press uses a ram with a force of 137 tons. That is strong enough to crack the cell walls of organic material, speeding up the digesting process.

Separating food waste

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.
