Optimisation in food recycling

Separation of approx. 98 percent of the inorganics

Verpackte Lebensmittel

The DRM hybrid process involves wet materials preparation for the recycling of foodstuffs. The simplest way is to crush biomass in accordance with the statutory requirements for hygienisation. Inorganic solids (e.g. packaging) are separated with high separation efficiency in the same operation. The digestion is carried out in a special mill with two rotors.
