Capturing Fugitive Methane Emissions From Slurry

BIOGAS
Unlike other slurry covers on the market, the CAPCH4 BIOGAS solution captures the fugitive methane emissions generated from slurry so it can be converted into useable energy.
The Bennamann Smartcover is designed to improve slurry management, increase slurry storage capacity and provide rainwater handling and recuperation.

Clean Air Act Compliance And 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.
Benefits
BIOGAS cover helps dairy farms cut operating costs by an average of £34,000 annually in our Pilot test during 2024. Savings include rainwater spreading expenses, lowers 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


Why Use A Bennamann Cover?
BIOGAS is a next-gen cover system that outperforms traditional options in every way— 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
