Bluemethane
Bluemethane offers a low‑energy, in‑line capture system that extracts dissolved methane from wastewater and other liquid waste streams, integrating with existing anaerobic digesters or treatment plants. The technology removes up to 85 % of residual methane, converting it into a renewable energy source and enabling operators to generate revenue from carbon credits while achieving measurable emissions reductions.

Problem
Methane dissolved in wastewater and other liquid waste streams is largely unmeasured and released to the atmosphere, contributing a significant portion of global greenhouse‑gas emissions despite being a recoverable energy source.
Solution
Bluemethane provides a low‑energy capture system that extracts dissolved methane from post‑digestion effluents such as sludge, digestate, or other liquid waste streams. The technology is installed downstream of existing anaerobic digesters and operates in‑line or in a recirculating side‑stream, removing up to 85 % of residual methane without disrupting the primary treatment process. Captured methane is of consistent quality and can be fed into existing power generation or gas utilization equipment, creating renewable energy and enabling revenue from carbon credits. The solution also delivers measurable emissions reductions—typically 200–300 t CO₂e per site annually—helping operators meet regulatory directives with minimal capital investment.
Target Audience
Primary customers are wastewater treatment facilities, biogas plants, and water utilities that operate anaerobic digesters and seek to reduce methane emissions while extracting additional renewable energy.
Features
- In‑line capture unit that integrates directly with existing anaerobic digestion or wastewater treatment plants
- Recirculating side‑stream mode to maximize methane recovery from effluent streams
- Minimal energy consumption; surplus energy generated when captured methane is converted to power
- High methane removal efficiency (up to 85 % from digestate) and consistent gas quality compatible with standard energy systems
- Enables emissions‑negative operation and quantifiable CO₂e reductions (200–300 t CO₂e per site per year)
- Supports revenue generation through on‑site energy production and high‑value carbon‑credit sales
- Designed for easy retrofitting with low‑impact installation and compliance with EU Industrial Emissions Directive
