Reduction in the volume and mass of solid waste is a crucial issue in regards to waste management. The SQR pelletizer densification technology allows for the processing of a wide range of low-density waste materials from plastic, RDF, SRF, to dry sewage sludge and biomass into high-density briquettes with an energy value of about 19-23 GJ per tonne. The end product, which is easily stored, transported and managed further can be used as a high-quality fuel and is ecological in nature.
