CPW — Compact Press & Liquid-Extraction System for Waste Streams
Efficient separation and compaction of waste streams are vital to optimising biogas plant performance. The CPW unit combines liquid extraction and solid-fraction extrusion in one machine — enabling you to recover valuable liquids, reduce solid volumes, and prepare feedstock for digestion or further processing with greater efficiency.
Product Overview
The CPW is a highly adaptable, industrial-grade system designed for continuous operation. It handles sludges, organic residues, mixed waste and high-moisture materials — compressing the contaminating fraction while extracting the liquid phase. This two-stage process produces a dense, homogeneous solid output and a free liquid stream suitable for reuse or further treatment.
Ideal For
Biogas plants seeking to separate liquids and solids efficiently upstream of digestion
Operations wanting to reduce haulage and storage costs by lowering solid volume
Facilities handling wet, high-moisture waste, where compaction improves logistics and handling
Industries with mixed organic waste streams (e.g., food processing, agricultural residues) looking for flexible technology
Key Features & Highlights
- Efficient liquid extraction from solid waste, sludge or slurries, enabling downstream reuse or treatment.
- Controlled extrusion of the remaining solid fraction, producing dense solids suitable for digestion, composting or refuse-derived fuel (RDF).
- Continuous-run design with a high-force compression screw mechanism, built for steady, reliable throughput.
- Robust construction using wear-resistant, high-quality materials (typically AISI 304 or 316 stainless steel for all contacting surfaces).
- Low energy consumption relative to throughput, making it both economically viable and environmentally sustainable.
- Multi-sector applicability: food & beverage waste, biomass preparation, high-moisture streams, volume reduction of residues.
