Biomethane plants

All ETW biomethane plants are characterised by their low energy consumption, high product purity and low operating costs. The ETW SmartCycle® process enables a high quality product gas with a constant calorific value even with varying raw gas amounts and compositions. Conditioning before feeding into the natural gas grid is not required. Our standardised modules enable very short implementation times. Special sizes are possible.
