‘Resource Efficient Use of Mixed Waste’ is a study conducted by BIO by Deloitte in partnership with BRE, ICEDD, VTT, RPS and FCT of NOVA University of Lisbon on behalf of the European Commission, led. The particular focus of the study was on Construction and Demolition Waste (CDW). The study aimed to investigate the current CDW management situation in EU Member States, identifying obstacles to recycling and deficiencies that could lead to non-compliance with EU waste legislation. Good practices in terms of creating conditions for increasing CDW recycling and for improving the quality of recycling and recovery were identified and a set of recommendations to address potential barriers formulated. In parallel, success stories of efficient CDW management were showcased in 6 case studies, illustrating key elements for success, as well as the necessary preconditions. Finally, the credibility of official CDW statistics was assessed, identifying the sources of inaccuracy and proposing measures for improvement. The preliminary findings of the study were discussed during a seminar in Brussels.
Construction and demolition waste (CDW) is one of the most significant waste streams in the EU, accounting for over 800 million tonnes per year. It consists of numerous materials, including concrete, bricks, gypsum, wood, glass, metals, plastic, solvents, asbestos and excavated soil, many of which can be recycled. CDW arises from activities such as the construction of buildings and civil infrastructure, total or partial demolition of buildings and civil infrastructure, road construction and maintenance. Different definitions of CDW are applied throughout the EU, which makes cross-country comparisons difficult.
Construction and demolition waste has a high potential for recycling and re-use, since some of its components have a high resource value. In particular, there is a re-use market for aggregates derived from CDW waste in roads, drainage and other construction projects. In view of the importance of this waste stream, the lack of comprehensive information regarding the situation in the Member States (and some uncertainty linked to official CDW statistics), it was appropriate to perform an in-depth analysis of the situation, identifying best practices, as well as the key factors to achieve a sustainable management of CDW and formulating recommendations for action.
The work was divided in 5 different interconnected tasks, including:
Task 1: Diagnosis of the situation as regards CDW management in the EU Member States, including the distance to the target defined in Article 11 of the Waste Framework Directive.
Task 2: Development of 6 case studies.
Task 3: Identification of good practices related to creating conditions for a sustainable management of CDW.
Task 4: Assessment of the reliability of CDW statistics, including plausibility checks. Proposals for the improvement of CDW statistics.
Task 5: Preparation and organisation of a seminar.

Six case studies
On 25 May 2016 a workshop was held in Brussels to discuss the findings of the study and present best practices. The workshop focussed on 6 key topics which were discussed in separate breakout sessions: targets for CDW and backfilling; waste prevention, demolition practices; reuse; markets for recycled products; data and statistics.
