RUNI dewatering screw press is developed for dewatering reject(waste from paper production containing plastic, wood, metal, laminated paper etc.) from the paper industry or for dewatering food waste from food industry. 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. Food waste reject (often household waste) can also be dewatered in the RUNI dewatering machine. The liquid from the food waste will be squeezed out through a matrix which has suitable holes. The RUNI dewatering screw press is very suitable for these rough tasks due to its strongly built construction and it is made for working 24/7.
