Runi - Screw Compactors

Industrial red plastic shredder machine with conveyor belt and control panel isolated on white background

Overview

The RUNI SK370 is the largest and most powerful screw compactor in RUNI's EPS (expanded polystyrene) recycling lineup, built for high-volume applications of over 50 tonnes annually. Designed to dramatically reduce the volume of EPS waste, this machine achieves a compaction ratio of up to 50:1, cutting down landfill transport from 50 truckloads to just one. With a block density of approximately 350 kg/m³, the compacted EPS becomes a valuable, stackable, and recyclable commodity.

Ideal for industrial-scale waste reduction, the SK370 delivers unmatched efficiency, minimal manual handling, and energy-saving operation without the use of heat.
