The Process
The City's compost is made predominantly from residential yard waste, tree clippings, grass clippings, and leaves. The process takes place on approximately 10 acres within the White Street Landfill. The City receives about 35,000 tons of raw materials each year and from that approximately 24,000 tons is processed into compost and the remainder is made into mulch.

Compostsite3_smAfter receiving the material, a grinder that is capable of grinding trees up to 30 inches in diameter, grinds the material into about two-inch size pieces. This material is then put in rows called windrows about 20 feet wide, 165 feet long, and 8 feet high. The internal temperature of the windrow is monitored and kept between 135 to 148 degrees. This process kills seeds and pathogens in the compost. When the internal temperature has reached 135 degrees for three days the product is considered free of pathogens and seeds. The entire curing process takes from eight to 10 weeks.

After curing, the product is run through a screening process using a trommel. This screening process separates the finer particles for bags and larger chunks of wood that have not decomposed. The finished product is piled and ready for loading.
