Best practices for Pre-demolition Audits ensuring high-quality RAw materials
The project will develop lifelong learning materials on best practices for pre-demolition waste audits.
The aim is to provide a harmonized approach for performing waste audits making references to legislation and benefitting existing studies, KCAs and information on best practices collected.
The planning of the education material will take into account the current gaps and knowledge needs identified in the European member states.
CDW and pre-demolition waste audit
Construction and demolition waste (CDW) is the biggest waste stream in the EU, accounting for over 800 million tonnes per year (excluding soil).
CDW has received more and more attention in the past few years as it is a lens to understanding the potential for resource efficiency improvement in the construction sector.
Indeed, CDW has a high potential for re-use and recycling, since some of its components have a high resource value and/or can be readily recycled.
In particular, there is a market for aggregates derived from CDW waste in roads, drainage and other construction projects. But the recycling potential of CDW is still underexploited.
The major challenge is the poor quality of the waste. The increasing awareness of hazardous substances in old construction materials, as well as more efficient detection methods, are expected to slightly decrease the recycling rate.
Here the pre-demolition audit is seen as an efficient tool to improve the quality of waste.
A pre-demolition waste audit is a tool enlisting and assessing all materials (and their potential value) within a building prior to demolition activity and is typically executed by external experts.
Pre-demolition waste audits are essential since they enable all the stakeholders involved to get information on the composition of waste and to make it easier to find markets for different waste types.
It is likely that the European Commission will recommend all Member States to make this pre-demolition waste audit mandatory to increase the high-quality recycling of construction and demolition waste.
A general framework for waste auditing in demolition activity has been developed in a study funded by DG GROW.
A pre-demolition waste audit, if performed correctly, can significantly promote the production of good quality raw material from C&DW works.
Supporting training material and leading waste auditing examples can strongly enhance the knowledge of professionals in the sector, increasing the quality of these pre-demolition waste audits.
This project is a continuation of the DG GROW contract work.
