About our composting process
About our composting process
The City’s composting facility began operating in January 2023 and consists of covered aerated static piles (CASP), with in-ground aeration utilizing Engineered Compost Systems (ECS) technology and a biofilter odor control system.
Biosolids from the Albany-Millersburg Water Reclamation Facility (AM-WRF) are mixed with ground up yard and tree waste using a specific “recipe” and placed into one of four composting bays. The mixture of nitrogen (biosolids) and carbon (wood material), along with the right amounts of oxygen and water, creates a controlled biological decomposition process known as composting. This is where microorganisms eat the organic waste and break it down, which generates heat that kills pathogens and stabilizes the material. The result is a stable organic compost product, that is rich in nutrients that can be used as a soil amendment.
The compost piles at the AM-WRF are continuously monitored for temperature, which controls the aeration system for consistent treatment throughout the pile. The material must reach and maintain a temperature of 55°C (131°F) or greater within a prescribed timeline needed to kill the bacteria and pathogens. It is then moved and mixed for additional composting to further stabilize and “cure” the material into a mature and rich compost. Overall, this composting process takes about 6 weeks per batch.
Environmental benefit
Albany and Millersburg selected composting for the biosolids treatment process because it provides an overall environmental benefit to our communities and turns waste into a desirable product. The composting system also lowers greenhouse gases by improving carbon sequestration in the soil and by preventing methane emissions through the aerobic decomposition process.
What are Biosolids?
Biosolid are a byproduct of the wastewater treatment process. During the treatment process the liquids are separated from the solids. These solids are then further treated physically and chemically to produce a semisolid, nutrient rich product known as biosolids. Biosolids can be further treated to produce a product that can be beneficially used as fertilizer or an amendment. Depending on the level of treatment and the method used in the treatment two regulatory types of biosolids can be produced, "Class B" and "Class A". The Albany-Millersburg WRF produces Class A compost from our biosolids. Class A compost is highly regulated and had unrestricted use to the public.

Exceptional quality compost
Exceptional quality compost
The City’s compost is a Class A biosolids product that meets the stringent Exceptional Quality standards of EPA Part 503 Biosolids Rule, which means it can be used anywhere without restrictions including home gardens and landscaping. When used as a soil amendment, Albany’s compost can help improve drainage in clay soils, will add nutrients, and help reduce the frequency of watering. Albany’s compost can also be used just as a ground cover instead of other mulches.
The City’s compost is monitored and tested in accordance with the EPA rules and annual reports are submitted to the Oregon DEQ.
