Future-proof Your Farm’s Costs
Bennamann’s CAPCH4™ Biogas System
Bennamann’s CAPCH4™ slurry lagoon technology is a key component of a farms transition to a net-zero future.
Capturing harmful methane emissions and ammonia, our solution generates significant savings including reduced chemical fertiliser costs, improved rainwater management and supplier incentives. Our technology supports the UK’s vision for energy security.
Unlike other slurry covers, the CAPCH4™ Biogas solution captures fugitive methane from slurry so it can be converted into useable energy.
Our Biogas Cover is engineered to enhance slurry management by increasing storage capacity, optimising rainwater recovery, improving NPK value retention & significantly reducing harmful emissions including ammonia.
How it Works

Our Biogas Cover future-proofs dairy farms by cutting operating costs. Savings include rainwater spreading expenses, lower fertiliser needs by boosting NPK nutrients in slurry, and reduced input costs for cake through improved protein content. This has a strong positive impact on CO₂ reduction on the farm.
Captured biogas is then cleaned and upgraded into useable fuel that can be used to power the farm or sold.
Clean Air Act Compliant
Bennamann’s Biogas Cover is an innovative slurry lagoon cover that helps dairy farms comply with the Clean Air Act by significantly reducing ammonia emissions. Its advanced design traps harmful gases, improves air quality, and supports sustainable, regulation-compliant farming practices.
Farming With Future In Mind
Farmers face challenges from increasing regulations and shrinking profits.
The Bennamann system captures fugitive methane, helping farms meet environmental requirements, cut costs and boost income with renewable biomethane.
Our CAPCH4™ solution has been designed with energy security in mind,ensuring farming remains viable and sustainable for future generations
The Bennamann Ecosystem
Bennamann’s CAPCH4™ ecosystem enables dairy and AD farms to capture, clean, store, and upgrade emissions from biogas into high-grade Biomethane.
Integrated technologies—from Smartcovers to Biocycles—create a closed-loop, renewable energy system for farm power, fuel, and revenue generation whilst reducing the environmental impact of farming.
