Ontario Composter Expands With Digestate Processing
Digestate is mixed with carbon sources using an Ecoverse DW 3080 stationary shredder/blender in the enclosed receiving hall at the composting facility.

All Treat Farms composts digestate from the anaerobic digester servicing the City of Toronto’s residential organics collection program.

Entrepreneur Connects Generators To AD
Napoleon Biogas, LLC processes organic waste from a neighboring Campbell Soup Company plant in Napoleon, Ohio. Underground pipes transport the organics from the plant to the digester (shown in foreground; biogas storage unit on right).

A Northeast company brings anaerobic digestion and renewable energy to the feedstock sources in Ohio and New York State.

Digester Biogas Heats Up Ethanol Plant
A DVO mixed plug flow digester (foreground) was installed at the Calgen Renewable Fuels ethanol plant (background) to process dairy manure from a nearby farm with about 10,000 gallons/day of food waste.

Pixley Biogas in Pixley, California is the state’s first anaerobic digester that is powering another renewable energy facility.

Boosting Biogas And The Bottom Line At WRRFs
The East Bay Municipal Utility District (EBMUD) in Oakland, California, was an early pioneer in codigestion at water resource recovery facilities (WRRFs), utilizing its excess digester capacity to process food waste streams.

“Traditional” WWTPs with anaerobic digesters are adding high strength food waste and FOG to become Water Resource Recovery Facilities with significantly smaller carbon footprints. Part I

Anaerobic Digestion In The UK — 2015 Update
Over 90 food waste AD facilities are in operation in the United Kingdom, such as the one near Bridgwater, England (shown above during construction), with many more in the pipeline.

The state of the AD industry in the United Kingdom is dynamic but the potential for further growth is huge, according to the Anaerobic Digestion and Bioresources Association.

Advances In Compost Heat Recovery
A “plug and play” Compost Heat Wagon, operating this winter at Vermont Compost Company, includes a high power aeration fan and an Isobar™ heat recovery system.

Two Vermont enterprises are using heat from active composting piles — up to 1 million Btus of energy per ton of material composted — in greenhouse operations this winter.

Adding AD To Existing Composting Site Footprint
The horizontal plug flow digesters, about 115-feet in length, have a longitudinal paddle shaft that slowly rotates. Material traverses the digesters over a typical 21-day retention time.

Two horizontal digesters and an in-vessel composting system enabled the City of Augsburg, Germany to expand processing capacity and include food waste.

Oregon WWTP’s Energy Net Zero Journey
Haulers connect to the FOG receiving station, comprised of two tanks, a FOG grinder, unload/tank mixing pump and a feed pump. Tipping fee is $.08/gallon. The plant has two 400 kW CAT engines (right).

Energy efficient digester mixers and treatment plant blowers, as well as installation of a solar array, FOG receiving system and two 400 kW CHP engines, are credited with helping to achieve energy net zero performance.
