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.
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.
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.
