Sheridan County Landfill

Sheridan County Landfill is a public landfill.

Sheridan County Landfill does not currently have an active landfill gas collection system or energy recovery project. Landfill gas is produced naturally as organic waste decomposes underground, primarily consisting of methane and carbon dioxide. Facilities without active collection systems may rely on passive venting to manage gas migration. As the volume of waste in place increases over time, the site may become eligible for a future gas collection or energy recovery project.
