Case highlight: organic waste to biomethane at Stanton Recycling

Waste utilised
0 tonnes per year
Biomethane produced
0 million Nm3 per year
Gas supply for
0 + households

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 it on a full EPC contract on the recycling site itself, with digestate treatment and heat recovery included.
