The Warm Hug Of Compost
In the “heating loop” warmed glycol, from the aeration pad, circulates into the pump house (1) via two variable speed and energy efficient pumps (2). This building houses the heating/cooling exchange system. Here, warmed glycol preheats domestic hot water that is used in the office and is pumped into the adjacent office/shop building. The system features manual valves (3) to switch between the compost-warmed glycol and well-water cooled glycol.

The Dirt Hugger composting facility utilizes heat recovered from active composting to warm its new
office building and mechanics shop.

Value Of Compostable Packaging As “Feedstock”
Compostable food service packaging was mixed with other feedstocks, e.g., yard trimmings, and run through a grinder.

Field trials at two composting facilities evaluated compostable foodservice packaging as a composting feedstock.

Upgrading Treatment Plant To Energy Net Zero
Scrubbing system (above) removes hydrogen sulfide, moisture and then siloxanes from the biogas prior to being used by the cogeneration engines. Pump trucks offload fats, oils and grease (FOG) into large storage containers (left). FOG is slowly injected into the digesters.

The City of Gresham, Oregon wastewater treatment plant generates about 10 percent more electricity than it needs via a combination of energy efficiency, codigestion and cogeneration, and a solar array.
