MARRUM, THE NETHERLANDS
This fully autonomous biogas plant of Biogas Marrum is engineered, constructed and owned by HoSt. The plant in Marrum in the North of the Netherlands, processes annually more than 36,000 tonnes of manure and produces annually 2.2 million Nm3 of biomethane with natural gas quality. The biomethane is fed into the gas network and is equivalent to the average yearly gas consumption of 1,550 households.
Biomass from cattle manure is stored in enclosed spaces. To prevent odour from spreading, the manure is unloaded in an airtight area on a moving conveyor floor. The air undergoes an advanced air purification treatment before being released back outside.
A unique feature of the installation is the integrated heat recovery system. Through the use of a heat pump, barely any heat is lost, which makes the installation highly efficient.
In addition to the biomethane production, high-quality fertilizers are processed for local sales in the agriculture sector and are used as raw material. The digestate is separated into a thick and a thin fraction. After digestate treatment, the thick fraction becomes an export-worthy residual product and is exported.
