UK estimates of recovery rates from non-hazardous C&D waste have been calculated for reporting against the EC Waste Framework Directive. Accurately quantifying C&D waste is challenging and whilst the absolute tonnage figures are subject to a relatively high level of uncertainty, there is not a significant impact on the final recovery rate. Under this Directive there is a target for the UK to recover at least 70% of non-hazardous C&D waste by 2020, which it is currently meeting.
