A large majority of Construction & Demolition Waste is recyclable but with the exception of a few Member States recycling up to 90%, the average recovery for EU28 is below 50%. Yet, the Waste Framework Directive 2008/98/EC has established the target of 70% of Construction & Demolition Waste to be recycled by 2020.

The consortium formed by TECNALIA and VTT will provide the Commission with a technical and economic study. The main objective of the study will be supporting the Commission in carrying out its tasks, in particular, those ones stemming from the policy process related to the Circular Economy and Resource Efficiency Opportunities in the Building Sector.

The scope of this technical and economic study is the provision of relevant inputs for and the development of specific tools and/or guidelines for the assessment of buildings and infrastructures prior to demolition and renovation, in order to improve the recyclability of CDW to be generated.

This study has the purpose of assessing within the Member States, the current regulatory, technical and economic conditions, the consequences and the opportunities of pre-audit prior to demolition and renovation projects to be performed in the aim of:

  • Preventing unnecessary waste
  • Enabling reuse and recycling of materials and components
  • Maximizing the value and sustainable use of construction material

The objectives of the study are divided into 3 main blocks, as follow:

1. The first objective of this study is to

    • assess the status of the current practices and conditions for the audit of buildings and infrastructures prior to demolition or renovation within the EU.
    • to gather the views from the relevant stakeholders with regard to pre-demolition/renovation CDW audit. Relevant stakeholders could be: Member States authorities, building and infrastructure project sponsors, prescribing technical consultants, building contractors, demolition contractors, recycling practitioners.


2. The second objective of this study is

    • to identify the key factors which could drive the implementation
    • to define the conditions – upstream and downstream – for successful implementation of pre-demolition/renovation audits
    • to list the regulatory incentives or obstacles
    • to assess the potential economic impacts on project costs and Life-Cycle-Costs of buildings and infrastructures


3. The third objective of this study is

    • to provide comprehensive and operational information
    • to draft methodological, technical and best-practices guidelines to be implemented by contractors and project sponsors in order to support national authorities for the actual achievement of the EU 2020 target for CDW recycling


To perform this study the work has been divided into 5 tasks:

  • TASK 1 – Stocktaking. This task consists in performing a review of the current situation in the EU with regard to the actual practices in assessing and managing the CDW streams prior to demolition/renovation of buildings and infrastructures.
  • TASK 2 – Needs for pre-demolition and/or renovation CDW assessment audits. This task should analyze, identify and list the needs for pre-demolition and/or renovation assessment tools with regard to generated CDW streams. It should also report the perception of relevant stakeholders concerning these needs.
  • TASK 3 – Guidelines for pre-demolition and renovation audits. Based on the analysis performed in the framework of the previous tasks, the Contractor should draft guidelines including a)principles and rules for how and when to carry out pre-demolition and renovation audits for buildings and infrastructures; b) conditions for data sourcing and collection c) format of audit reporting and d) further exploitation of audit outcome by project sponsors, contractors, and authorities.
  • TASK 4 – Proposal for implementation of the guidelines. In this task, the Commission will be provided with a set of actions for implementation of the proposed guidelines for carrying out pre-demolition and renovation audits for buildings and infrastructures among the Member States and the actors within the EU construction sector. These actions could also be differentiated according to the current conditions and situations of the Member States with regard to their actual management practices for CDW.
  • TASK 5 – Stakeholders’ consultation. To perform the previous tasks, the Consortium will consult representative and relevant stakeholders and national/regional authorities. The results of these consultations should be presented in a specific part of the progress and final reports or annexed to it. This task includes the performance of a final workshop to finally agree the work carried out with stakeholders.
