This guidance document aims to give an overview of potential hazardous substances that might occur in construction products and when appearing as waste need attention during renovation and demolition activities. Focus in this guideline is on hazardous substances regulated by EU or international agreements or national legislation.

Although the present legislation restricts the use of many hazardous substances in new building products, there is a considerable concern for compounds present in old construction products, since their presence in construction and demolition waste may limit the recyclability of the material and potentially cause waste management problems. One group of substances that has recently received attention are persistent organic pollutants (POP substances) such as e.g. some brominated flame retardants.

Important characteristic of the construction and building products is the relatively long life span. Because of long lifespan the restricted substances will enter the waste stream many decades after a ban has been placed on their use and they can therefore be found in renovation or demolition waste for a long time. Many of these substances provide important functionality in a wide range of products, e.g. flame retardants.

Besides hazardous substances also degradation in composition and quality aspects (e.g. mould) of construction products needs to be considered.

This document is part of the pre-demolition overall guidance document developed in the PARADE project.

The Secretariat of the Strategic Approach to Chemicals Management (SAICM) and the University of Cape Town (UCT) have launched a Community of Practice (CoP) on Chemicals and SDGs to bring representatives from different sectors together and to create a learning network around issues related to addressing Chemicals and the Sustainable Development Goals (SDGs). This is a compilation of summaries of the discussions, which took place in 2022.
