RDF/SRF is waste used as fuel in incineration plants for energy production or in cement kilns. For optimizing the value of the fuel it can be necessary to dewater it. The RUNI screw compactor is able to dewater RDF/SRF in a continuous process with a low use of energy. The conditions at RDF facilities are extremely demanding and plants are working 24/7 all year round. In the RDF there are often abrasive elements like sand. Therefore great demands are required of the machine and the RUNI can do it.
