Valorise sludge

We're here to help you reduce the amount of sewage sludge you generate and make the most of its energy potential through innovative solutions such as methanisation, incineration and thermochemical processes.

Valorise sludge

To support the ecological transition on a regional level, we turn sewage sludge from wastewater treatment into a local, renewable energy source.

We harness the energy potential of nitrogen- and phosphorus-rich sewage sludge from wastewater treatment plants, converting it into energy (heat, electricity, biomethane) or organic matter using innovative solutions such as methanisation, incineration and thermochemical processes. Sludge can be used as an organic fertiliser instead of chemical fertilisers, helping to promote more sustainable agriculture.

We work with you to define the most appropriate treatment and recovery process for each type of sludge produced and the context for each wastewater treatment plant, taking account of the challenges faced and local regulatory requirements.

Our solutions aim to turn sewage sludge into a high value-added material that helps to reduce your area’s greenhouse gas emissions, support the transition to cleaner energy sources and develop the circular economy in water treatment and agriculture.

We create local circular economy loops from wastewater and waste to support the energy transition in local areas.

We can also support you in your other water cycle management challenges
