Mechanical separation of impurities in biowaste ...
Apr 01, 2020 Typically, the first step of a mechanical processing is the bag opener or shredder, which aims at separating the biowaste trapped inside plastic bags and making it more homogeneous. Other standard processes include sieves, presses and metal separators, which are used for separating the different fractions, depending on size and composition.
