Biogas plants for municipal organic waste and waste management
Turn collected biowaste into renewable energy
Municipalities and waste management companies handle rising volumes of source-separated food and garden waste, alongside legal targets to divert biodegradable waste from landfill. A biogas plant for municipal organic waste converts those streams into renewable energy and recovered nutrients, turning a gate-fee-funded disposal duty into an energy and biofertiliser output. HoSt Bioenergy Systems has delivered more than 450 renewable energy projects worldwide, including plants for waste processors such as Attero, Twence and Stanton Recycling. For the underlying technology, see our organic waste biogas plants and anaerobic digestion pages.
Which municipal waste streams suit anaerobic digestion
What a municipal biogas plant produces
- Biomethane for the grid and transport
Raw biogas can be upgraded to biomethane for grid injection, or compressed to bio-CNG as a fuel for a collection fleet. - Biofertiliser and compost from digestate
After sanitation, digestate is valorised as an organic biofertiliser, and its solid fraction can be processed into compost, returning nutrients to the soil. - Food-grade bio-CO2
Biogenic CO2 separated during upgrading can be captured and liquefied to food-grade quality as an extra revenue stream.
Biogas plant at Stanton Recycling
At Stanton Recycling in Ilkeston, UK, HoSt delivered a turn-key biogas plant that digests food and green waste and upgrades the raw biogas to biomethane, raising methane content to 97%. The plant produces 4.7 million Nm3 of biomethane a year, enough to supply more than 3,800 households, injected into Cadent’s gas grid. HoSt built the plant on a full EPC contract on the recycling site itself, with digestate treatment and heat recovery included.
