Reject from industrial productions very often contains a lot of water. To save cost on transport and landfill it is beneficial to remove as much water as possible. Here the RUNI dewatering press has shown its worth. RUNI dewatering screw press is developed for dewatering of reject(waste from paper production containing plastic, wood, metal, laminated paper etc.) from the paper industry or for dewatering food waste from food industry. Before waste from the paper production can be transformed to recycling paper all unwanted material must be sorted out. This water containing reject is both expensive to transport and to dispose of, but after compacting and dewatering in the RUNI dewatering press it can now go to incineration at a much lower cost.
