Newgrow Compost

The Composting Process:

Wastewater treatment facilities collect and treat wastewater from residential sources. The liquids and solids are separated during this process. 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 to create compost.  It is "de-watered" and mixed with clean sawdust then placed into temperature controlled bays where it must reach temperatures of 52-55 C for a period of time - the "cure process". This composting method removes or "cooks" out the pathogens - leaving 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 or exceed the EPA standards. Batches that fail to meet standards are not placed out for public use.

THIS PRODUCT IS FULLY CURED TO MEET EPA  "CLASS A" standard FOR USE WITHOUT RESTRICTIONS. It exceeds all EPA and DEQ standards. It is low in metals, free of pathogenic organisms. It has a neutral PH of 7.0   It is tested and monitored throughout the heat cure process.

NEWGROW COMPOST is a "CLASS A" product with no restriction on its use.
