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).

 About CIRCuIT
The Circular Economy wiki is supported by the Circular Construction in Regenerative Cities (CIRCuIT) project, which is funded by the European Union's Horizon 2020 research and innovation programme. CIRCuIT is a collaborative project involving 31 ambitious partners across the entire built environment chain in Copenhagen, Hamburg, Helsinki Region and Greater London. Through a series of demonstrations, case studies, events and dissemination activities, the project will showcase how circular construction practices can be scaled and replicated across Europe to enable sustainable building in cities and the transition to a circular economy on a wider scale.
