1577 MMBTU/year*

How can it be used?

Direct Use

Utilize biogas directly or after upgrading as renewable natural gas for cooking, heating, or other thermal applications.

Electricity and Heat

Use biogas in combined heat and power (CHP) systems to efficiently produce both electricity and heat.

Electricity

Convert biogas into electricity through electrical generators.

Vehicle Fuel

Upgrade biogas and use it as a renewable transportation fuel in vehicles that run on CNG.

^{*Nominal rate assuming typical food waste inputs. Peak output can be 1.7X higher. Actual outputs may vary based on feedstock.}

Case studies

University of California Davis

Core 925

This Core system is capable of accepting up to 3.35 tons/day of mixed food waste feedstock. The system includes a 65kW combined heat and power micro-turbine to supply renewable energy and heat to Lineage Logistics, a food distribution hub in southern California. The system also has a second-stage pasteurization system to condition the biofertilizer output for local strawberry production and other local farm systems.

Vashon Bioenergy Farm

Core 1500

Owned and operated by Chomp, Vashon Bioenergy Farm sits adjacent to a tofu manufacturing plant. This Core 1500 unit offers continuous distributed energy and supplies renewable natural gas back to the tofu plant to run their boilers and CNG to fuel vehicles, reducing disposal and energy costs simultaneously. The biofertilizer is distributed to local farms on the island.

Grinding station

Your organic waste is deposited into the digester here, initiating the digestion process. Waste is emulsified into a thick, smooth liquid.

Dosing tank

Every two hours another helping of waste is automatically metered—no human intervention necessary—ensuring a sustained, efficient process.

Digester

Within the digester, thousands of microbes chomp away at the organic waste, continually creating valuable biogas and biofertilizer.

The biogas is harnessed as an energy source and the biofertilizer can be used to provide plants the nutrients they need to thrive. It's the magic of nature and technology combined!
