Chloe

Maximising methane capture from post-digested sludge

Technology that provides a practical sludge degassing system designed specifically for UK sludge operations.

Chloe

The answer to methane degassing and recovery for UK water utilities.

  • Reduce methane emissions.
  • Safer sludge handling.
  • Manufactured in the UK.

Bluemethane’s mission is to eliminate methane emissions from waste streams by helping water utilities reduce emissions from post-digested sludge.

Chloe has been designed for UK water companies to provide a simple, proven way to remove dissolved and entrained methane from post-digested sludge. Chloe integrates easily into existing or new treatment flowsheets, helping water companies degas, recover and reuse biogas.

Manufactured and assembled in the UK and supported by a strong domestic supply chain. Bluemethane supports single-site installations or multi-site programmes with confidence.

Reducing methane. Proven in operation.

When methane in digestate becomes challenge

Residual methane in post-digested sludge creates avoidable emissions, making it challenging for water utilities to meet their emissions targets. It is also wasted energy.

Most sludge treatment centres don’t need complex processes. They need a reliable way to remove residual and entrained gas that works with existing infrastructure.

Inside Bluemethane’s Chloe 

This animation demonstrates how Chloe safely removes dissolved methane from water and wastewater streams before it can be released into the atmosphere.

Through controlled separation and capture, the system reduces emissions at source, providing water utilities and AD plant operators with a practical, measurable solution to methane mitigation.

Delivery. Scale. Confidence.

The modular design allows units to be installed with minimal disruption and phased in over time, or delivered all in one go.

  • Safer sludge handling — Degassed sludge reduces risk during storage, transfer and dewatering.
  • Lower operational burden — Fits into existing sludge treatment lines without adding complexity.
  • Useful energy recovery — Recovered gas is returned to the site for electricity generation or biomethane upgrading.
  • Meets net zero targets — Reduce emissions and lower carbon footprint.
  • Forms a critical part of a EU Industrial Emissions Directive solution.

Chloe is WIMES compliant and certified to ATEX standards.

The benefits

Installing our methane capture technology brings big benefits:

  • Modular system with minimal installation disruption.
  • Suitable for phased roll-out.
  • Proven in live sludge treatment environments.
  • Designed specifically for UK water companies.
  • Using gravity, pressure change and turbulence – removing the maximum methane with minimal energy and cost.

Reduced emissions, increased biogas recovery and safer operations.
