Our biogas solutions

Dairy

HoSt Group - Biogas plant
Our biogas plants for dairy farms include anaerobic digesters and valorization technologies that turn dairy manure into RNG and other valuable commodities resulting in greener operations and increased revenue.

Food waste

HoSt biogas plant - organic residues & manure
By converting food waste into valuable RNG using anaerobic digesters and other innovative technologies, we provide an efficient solution to food waste management. This results in a more sustainable and energy-efficient food industry.

WWTP

HoSt biogas plant - organic waste
For WWTPs, our biogas systems offer a dual advantage. Transforming sludge into RNG through anaerobic digestion, we enhance the efficiency and sustainability of wastewater treatment processes.

Manure

HoSt biogas plant - Microferm
Our manure biogas plants turn manure management into an opportunity. HoSt transforms any manure into RNG through anaerobic digestion, introducing a reliable revenue stream for developers and farmers.

Our turnkey biogas plant solution

Our biogas plants can be supplied with in-house biogas upgrading, bio-LNG, bio-CNG, and CO2 liquefaction technology. The image below is an illustrative representation including multiple anaerobic digesters.

Digesters & after-digesters

The anaerobic digestion process occurs within the digesters. An anaerobic digester with an after-digester results in increased biogas output, due to a higher conversion rate of organic matter.
Anaerobic digestion

HoSt North America’s biogas facilities are equipped with other proprietary technologies along with high-tech anaerobic digesters. We offer all essential add-on renewable gas technologies and valorization under one roof. This integrated approach simplifies operations and delivers added value, making us a reliable partner for renewable natural gas (RNG) needs.

Waste utilized
0 tons per year
Biomethane
0 million Nm3 / year

Built at Charlton Park Estate in Malmesbury, England, this biogas facility utilizes anaerobic digestion and membrane technology to produce biomethane, promoting decarbonization and energy security. This renewable substitute to fossil fuel derived natural gas is injected into the UK’s established gas grid. Post-digestion, the remaining material is pasteurized and applied as organic biofertilizer on the estate’s land.
