Processed Wood Chips
As part of the City's Yard Waste Program, the City of Gillette collects tree branches, brush and similar vegetation from the public at the City's Wastewater Treatment Compost Facility. Wastewater Staff grind and process the tree branches, brush and similar vegetation into wood chips for use within the City's biosolid compost material.
Currently, the City has a surplus of wood chips at the Compost Facility. Selling the surplus wood chips to the public will generate revenue to offset the costs associated with grinding and producing the processed wood chips.
The cost for the wood chips is $20 per cubic yard.
