We combine anaerobic digestion, gas purification and modular energy systems for industrial wastewater, palm oil residues and organic solid waste.
Our scope spans individual equipment supply and EPC (Engineering, Procurement and Construction) contracting through to DBOO (Design, Build, Own and Operate) solutions.

Digestion
CSTR Plus is a tank-based digester designed for palm oil mill effluent. It runs at a volumetric loading above 5 kg COD/m³·d, compared with below 1 kg COD/m³·d in a lagoon, and needs about half the volume. Sludge is discharged continuously, so performance does not fade year after year.

Our bio-methanol plant brings 80 process units together in 12 main skids. Every skid is sized for road transport and tested before it leaves the factory, so site work is mainly lifting and connecting.
