The Process

Wastewater treatment facilities collect wastewater from residential sources and must treat the wastewater to meet safety standards before release. The liquids and solids are separated during treatment. Microorganisms then digest the solid material, leaving behind a byproduct that mostly consists of the cells of these miniature cleaning crews.

The City of Newberg then uses this by-product in the composting process.  It is further "de-watered" and mixed with clean sawdust

and placed into temperature controlled bays where it must reach temperatures of 52-55 C for a specific number of consecutive days. This composting method removes or "cooks" out the pathogens - leaving high quality clean compost.

The "bays" are monitored 24 hours a day with temperature probes placed at regular intervals. In addition the compost is tested in our laboratory and must meet EPA standards or it is not placed out for public sale.
