Requirements for pre-demolition audit

A pre-demolition audit is a tool that can be used to both identify hazardous substances and assess the materials to be removed from the building or infrastructure, and consequently their potential value, prior to the demolition or renovation activity can be established. Audits are essential since they enable all stakeholders involved to get information on the composition of waste and 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 audit mandatory to increase high quality recycling of construction and demolition waste. The report presents the current pre-demolition audit systems and existing guidelines in Denmark, Finland and Sweden. The report gives recommendations on key elements to be included in audits for improving the quality of the construction and demolition waste.



Practice outside Denmark, Finland and Sweden

A mapping of practice outside the project group was conducted in order to identify activities that could be used to support the project recommendations (e.g. experience or systems implemented in other countries). Only a few countries have introduced a mandatory pre-demolition audit in legislation, but several countries have voluntary based systems focusing on some parts of the auditing, typically on the identification of hazardous waste.
