Retrofit Existing Digester(s) to Triple its Capacity

Omnivore™ is an advanced high solids approach to digestion which incorporates Anaergia’s intelligent mixing and robust thickening systems to triple the capacity of an existing digester (typically 2 to 3%) into a high-solids Omnivore™ digester (5 to 8%).

Low Footprint for new Digesters: Reduce requirements of new digester construction to 1/3 of the volume and footprint required by traditional digesters, reducing CAPEX and associated OPEX.

Co-Digestion Made Easy: Omnivore™ enables co-digestion of local organic waste streams, generating additional revenue and making plants energy positive. Omnivore™ unlocks digestion capacity in existing digesters which can be used to co-digest not only fats, oils, and grease (FOG) but also local organic streams like food processing waste, Source Separated Organics (SSO), organic fraction of municipal solid waste (MSW) which was prepared and treated by Anaergia’s Organic Extrusion Press (OREX™).

Improved Performance: Omnivore™ offers operational control and flexibility. Easy maintenance includes the ability to adjust mixer position to break up floating layers and re-suspend grit, and access without taking the digesters out of service.
