OREX™

Maximize organics recovery from mixed waste. no source separation required.

Anaergia’s OREX™ reliably separates wet organic and dry fractions from mixed municipal solid waste (MSW), recovering over 90% of putrescible organics without the need for source separation. This high-efficiency extrusion system produces a clean, digestible wet fraction ideal for anaerobic digestion and a dry fraction with increased calorific value for RDF (Refuse Derived Fuel). The system supports smooth operation and low maintenance, while helping facilities reduce landfill waste and boost renewable output.

OREX Features

Anaergia’s Organics Extrusion Press

Reliably and efficiently separates solid waste streams into wet organic and dry fractions, driving significant value through both resource recovery and diversion.

Organics Extraction & Recovery

OREX™ generates a clean and highly digestible wet fraction ideal for conversion to biogas and fertilizer.

Residuals Diversion

Anaergia facilities maximize recovery of plastics, paper and metal while transforming the non-degradable and non-recyclable rejects coming out of OREX™ into a dense Refuse Derived Fuel (RDF).

Technical Specifications

OREX™ is a compact, modular extrusion system designed for high-throughput processing of mixed waste streams. It efficiently separates wet organic content from dry contaminants. Compatible with MSW, SSO, food, and commercial waste, it delivers consistent slurry quality and helps reduce the burden on downstream digesters.

Reference Facilities

Enerbio, situated in Italy and commissioned in 2012, stands as a remarkable example of sustainable energy production through the conversion of agricultural waste into electricity. The plant uses a wide range of organic materials as feedstocks for its energy generation process.

South San Francisco-San Bruno Water Quality Control Plant (WQCP) is a nine million gallon per day (MGD) facility that serves 100,000 people in California’s Bay Area.

Ambiente & Risorse plant in Broni, italy has the capacity to treat up to 40,000 metric tons of source separated organics a year and convert it into about 3,900,000 cubic meters of renewable natural gas (biomethane).
