SSWI operates the largest mixed co-composting facility in the nation.

Sevier Solid Waste takes all the waste from the City of Gatlinburg, Sevierville and Pigeon Forge; Sevier County and the Great Smoky Mountains National Park.  All the waste (commonly called MSW), is mixed with bio-solids and pushed into large in-vessel digesters for three days.  During this time, all the organic waste (food, paper and cardboard), becomes compost.  

All the in-organics are removed from the compost and landfilled.  The compost is then screened and placed in windrows where it will remain for 28 days.  After the final screen, SSWI has Grade A compost.

SSWI produces over 50,000 tons of compost each year.  This compost is spread on local farms and used for erosion control.
