Landfill reclamation is a relatively new approach used to expand municipal solid waste (MSW) landfill capacity and avoid the high cost of acquiring additional land. Reclamation costs are often offset by the sale or use of recovered materials, such as recyclables, soil, and waste, which can be burned as fuel. Other important benefits may include avoided liability through site remediation

Reserves near the surface can only be accessed through mining. In this process, the bitumen is dug up, mixed with water and agitated to separate the bitumen from the sand and clay. Mining operations require the removal of all vegetation and top soil to access the raw oil sands. This material is then stored for use later in reclamation.
