Separate Organics from Municipal Solid Waste

Royal Dutch Kusters Engineering - Organic Liquefying Press
The Organic Liquefying Press separates the organic fraction from mixed household waste. The OLP enables smart waste management by liquefying food and other organic material using a pressure of up to 280 bar. It passes a virtually pure organic material stream to an (anaerobic) digester to make biogas and RDF. biogas potential could increase by almost 30%. Simultaneously, the separated solid fraction can be used for further recycling or as an alternative energy source.

Benefits of the Organic  Liquefying Press

Organics icon

Unmatched resource extraction

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

Deployable for a wide range of feedstock

 There are almost no restrictions in MSW feedstock and the OLP can handle stones, metal and (uniquely) glass without problems. In principle, only inerts need to be separated out.

Recyclables icon

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 the organic material, speeding up the digesting process.
Smart segregation and increased digester efficiency

Smart segregation and increased digester efficiency

By extracting up to 95% of organic material, the OLP increases throughtput. It improves on conventional processing technologies by segregating small plastics and wood particles from the organics, which float on top of the digester liquid.

Open architecture and predictive maintenance

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

Optimize the calorific value of RDF

Varying on the material, the OLP significantly dries the RDF fraction as it drains the wet material. In some cases this could exceed even 50% moisture reduction.

How to achieve unmatched resource extraction from municipal solid waste

To extract the organics the material is pressed through a sieve by means of hydraulic pressure. The two resulting fractions are the dry RDF and wet organic fraction with a high level of purity. The self-learning press automatically adjusts its settings for optimal output and energy usage. This way, the best result can be achieved with an increased biogas potential of up to 30%. Simultaneously, the dried RDF fraction, can be further upcycled or used for its high calorific value as alternative energy.

What is the Organic Fraction of Municipal Solid Waste (OFMSW)?

Although contaminated, this waste stream can be quite valuable with proper treatment.
