Dickson County C&D Diversion Study
When the Dickson County Solid Waste Department sought to extend the lifetime of a C&D landfill, they consulted Wilmot to formulate a cost-effective diversion strategy.
Background
As Middle Tennessee’s growth skyrockets by attracting businesses and residents, the demand for new construction - and disposal of construction and demolition (C&D) debris - is on pace to increase steadily over the coming decades. Covering about 85 acres, the Dickson County landfill features an active Class III disposal area that accepts C&D waste. Dickson County contracted with Wilmot Inc to find ways to lengthen the life of their landfill and avoid costs associated with operating as a transfer station post-closure.
Wilmot’s Role
Wilmot forecasted the landfill’s remaining life, conducted a waste audit of materials, and assessed the feasibility of various diversion strategies at the landfill. We then implemented a set of the most cost-effective diversion strategies in conjunction with a tip fee adjustment to incentivize generators to self-sort their materials and to cover increased operating expenses. Following our recommendations, the County will be able to extend the landfill’s life by 36 years, nearly tripling its current life expectancy, while also avoiding substantial operating costs. Over the long term, Wilmot’s plan will save income for taxpayers and generators, support local reuse markets, and stimulate the circular economy.
