33. The importance of quality assurance and data in closing the C&DW loop

In Flanders, a densely populated area with no space for landfilling, recycling of construction & demolition waste (C&DW) is already a fact: over 90% of all waste is recycled. However, there are ways to do better, and to go even further, in different directions.

On the one hand, the quality of the recycled aggregates and the trust of users and designers in these products can be improved. Quality assurance systems and traceability organisations (from source to applications) are important tools to guarantee that recycled materials are free of hazardous components and technically fit-for-purpose.

On the other hand, the high recycling rate is due to the use of concrete and bricks in new applications. Other, non-stony materials, still face a lot of challenges. Creating a database which contains all materials inventoried during pre-demolition audits, allows to identify the available materials in buildings that will be set free in a short and mid-long term. This crucial information for producers, users and recyclers of materials is a first and essential step to further enhance the circular economy. It will allow them to align investments in recycling capacity, based on actual figures and trends.
