About

Orège Green Gas-Unlocking the Full Potential of Biogas

Turning Underperforming Digesters Into Energy Assets – Without CAPEX

Most anaerobic digesters underperform not because of their design, but because of the poor quality of sludge they receive. Orège Green Gas changes that.

Our compact, modular, and chemical-free pre-treatment unit conditions and thickens raw sludge in a single pass – from 2–3% to 6–8% dry solids, thanks to our patented SLG-F™ technology. No chemicals. No heat. No CAPEX required.

Key Benefits

  • Up to +40% more biogas yield

  • Lower polymer use & reduced sludge volume

  • Mobile and turnkey deployment – launch in days

  • Fixed installation option for long-term performance

  • Ideal for plants without Thermal Hydrolysis (THP) or the budget for it
