Restoration Soils is a thermophilic composting facility located in Flagstaff. We utilize a variety organic waste streams (nitrogen) and mix with biomass (carbon) feedstocks. We mix water, carbon and nitrogen together to activate the biological processes that starts the thermophilic composting process. Our piles take about 6-8 months to go through the active compost process and transform waste products in to useful soil amendments and finished compost. We monitor the temperatures of our piles to ensure they hit minimum of 135 F for three days. Typically our windrows run from 140 to 160° .

Our protocol calls for mixing and turning regularly and ensuring adequate moisture and oxygen enters the piles. We test for nutrient content, PH level and carbon: nitrogen ratios. We screen our compost after it has cooled down to 125° with a 3/8” minus screen.

Restoration Soils does not currently accept any manure or animal waste.

Because we utilize and finish smaller batches (approximately 20 to 40 yards at a time) we do not always have compost available.

Please email us at compost@restorationsoils.com if you would like to be put on a waiting list in case we are sold out.
