CL:AIRE Definition of Waste:Development Industry Code of Practice

CL:AIRE has published figure demonstrating that since 2009, 813 Definition of Waste:Development Agency Code of Practice (DoWCoP) declarations have been received by the Environment Agency (EA).

The Code of Practice (COP) aims to reduce the regulatory burden on redevelopment sites by providing a framework for managing materials for re-use, without requiring wastes management permitting or exemptions to be in place.  The outcome of this is more sustainable site development, and less material going to landfill as waste.

The COP covers material generated on a site that is to be re-used.  For example, managing cut and fill materials from an earthworks balance, the direct transfer of material from a donor site to a receiving site, e.g where subsoil and clay is being excavated to achieve development levels and is no longer required for its site of origin, so it is transferred to another site where there is a material shortfall for earthworks/bunds etc, and for cluster projects where a treatment centre is established and receives wastes from various sites for treatment and then re-use.

The main document supporting this process is the Materials Management Plan (MMP).  This is established by a relevant party such as a contractor or consultant involved on the redevelopment project, and the MMP is then signed off by a Qualified Person, who then completes the documentation to register the scheme with the EA.

The MMP identifies the routes by which material will be sourced and re-used, and it provides all relevant info such as specifications for the works, drawings and cross sections.  It must document volumes to be produced/re-used, and it must be clear that the process is re-using materials where there is a predefined need, rather than being a vehicle for losing material to avoid paying landfill tax/fee’s.

Upon completion of the works, a Validation report is prepared which documents how the work has been completed in accordance with the aims of the MMP, and the final volumes used on site.

CL:AIRE estimates that upwards of 18 million m3 of material has already been diverted from landfill using this framework.

If you have a redevelopment scheme that could benefit from this approach, and would like to find out more information, you can contact us here at DBS, or, you can find more information on the CL:AIRE website –

DBS can also provide Qualified Person services for project audit, EA declarations and the preparation of Validation Reports.
