Definition of waste: Code of practice
The Definition of Waste: Code of practice (DoW:CoP) was launched in September 2008 by the independent research group Contaminated Land: Applications in Real Environments (CL:AIRE). It is used to support and enhance the sustainability and cost-efficiency of land remediation and development projects.
It has been used to provide a consistent and efficient process for the reuse of excavated materials, such as the direct transfer of clean, naturally-occurring soil materials between sites. It also relates to the conditions required to support fixed soil treatment facilities, and the reuse of both contaminated and uncontaminated materials.
- Ensure an adequate Materials Management Plan (MMP) is in place.
- Ensure the MMP is based on an appropriate risk assessment.
- Ensure materials are treated and used as set out in the MMP (as demonstrated in a subsequent Verification Report).
For more information, see CL:AIRE.
