Stimulating reuse with a materials passport
Registration and documentation of products and materials used in the built environment can help reuse them in a circular economy and eliminate waste.
A materials passport includes digital data, such as the history of building materials, the extent to which building components can be reused, how this can be done, the potential for recycling and biodegradation. If buildings ever need to be dismantled, we know exactly what materials they contain and how they can be reused.
Through Madaster Belgium's online materials cadastre, a materials passport can be generated at any point in the project lifecycle, providing insights into the financial and circular valuation, toxicity and reuse potential of buildings and real estate projects.
Julie De Pauw, Development Manager Real Estate at PSR - Jan De Nul Group:
"Madaster allows to map the reusability of projects but also to make the best choices in the design phase in function of circularity and CO2 impact. The sector is asking for more circular construction and Madaster offers a concrete tool to get started with this. It fits in with the sustainable and socially responsible business practice within Jan De Nul Group."
Johan Klaps, director Madaster Belgium:
"It is hugely important for the Belgian circular construction economy that frontrunners like Jan De Nul Group join Madaster. They are thus one of those partners who can pull the entire chain in the construction sector into the bath to start documenting materials and products for later reuse."
Madaster is a concept developed by the Dutch-German architect and circular thinker Thomas Rau, which was also launched in Belgium in 2021, following the example of Germany, Switzerland, Norway and the Netherlands.
Madaster facilitates the registration, organisation, documentation, storage and exchange of data about all materials, components and products used in the (built) environment, in such a way that materials remain available for future generations through reuse and transition to a circular economy.
The system supports circular business models in the building sector by creating transparency about the nature and value of reusable components in a building.
Corporate Social Responsibility at Jan De Nul Group
A global player such as Jan De Nul Group has a meaningful impact on society. We strive every day to create value for that society. Corporate social responsibility (CSR) is therefore an integrated part of our core business.
We go for zero: not only in words, but also in concrete action. Our awareness programme Code Zero unites all sustainable initiatives into four pillars: Zero Emissions, Zero Accidents, Zero Waste and Zero Breaches. A milestone, rather than a starting point. And only one piece of the puzzle. To make a real difference, we need everyone’s support, from our own employees and clients to suppliers, local communities and governments.
