The new technology in the bio-sector
The difference from conventional shredders has to do with how the QZ works. The feedstock is not shredded with knives or strainers. Instead, a rotating chain inside the vessel creates the desired effect. The chain works like a mortar that crushes herbs. This results in the attack surface for the bacteria being increased. In the fermenter this effect then sets off a faster decomposition and thus produces a higher gas yield.
The QZ’s chain smoothly exposes foreign matter. And the robust machine does not stop even when faced with solid metal parts. Breaking open packed groceries or plastic bags does not pose any problems either. In a subsequent separation process, the exposed foreign matter can then be eliminated completely and free of organic matter.
