Capturing Fugitive Methane Emissions From Slurry
BIOGAS
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.
Clean Air Act & Energy Independence
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
BIOGAS Cover future-proofs dairy farms by cutting operating costs by an average of £34,000 annually.* Savings include rainwater spreading expenses, lower fertiliser needs by boosting NPK nutrients in slurry, and reduced input costs for cake through improved protein content in slurry. Average CO₂ reduction per farm is 282 Tons CO2e.
*based on our Pilot test during 2024.
Why A Bennamann Cover?
BIOGAS Cover is a next-gen solution that outperforms traditional cover systems in every way. Providing improved rain water handling, regulatory compliance, durability and efficiency, while uniquely capturing biogas for on-farm energy use. This slashes energy costs and dramatically reduces the farm’s CO₂ footprint for true sustainability.
