Organics Extrusion Press OREX: Recovery from Solid Waste


The Organics Extrusion Press (OREX) reliably and efficiently separates a variety of waste streams into a wet organic fraction and a dry fraction, driving significant value through both resource recovery and diversion.



An OREX processing line is a key component of an integrated solid waste program. The OREX physically seperates mixed solid waste into two components: wet and dry fractions. Unlike traditional screens, the OREX is capable of recovering up to 95% of food waste found in Municipal Solid Waste with < 1% contamination. Waste is fed into a perforated chamber, where it is compressed under high pressure (4,000 psi). The wet fraction of waste is squeezed through the perforations, making it available for anaerobic digestion. The separated dry fraction can be conveyed to a transfer pit or upgraded to a solid engineered fuel. The dry fraction has a lower moisture content, increased density when compared to the incoming solid waste, and increased energy value.
