CL:AIRE Definition of Waste: Development Industry Code of Practice (DoW CoP)

The DoW CoP provides a clear, consistent and efficient process which enables the reuse of excavated materials on-site or their movement between sites.

Use of the DoW CoP supports the sustainable and cost effective development of land. It can provide an alternative to Environmental Permits or Waste Exemptions.

The DoW CoP enables:

  • the direct transfer and reuse of clean naturally occurring soil materials between sites
  • the conditions to support the establishment/operation of fixed soil treatment facilities
  • the reuse of both contaminated/uncontaminated materials on their site of origin and between sites within defined Cluster projects
