1. Will information carriers for a building’s material passport still exist after 50 years, given the rapid disappearance of disks, tapes, and IT systems due to digitalisation??
Yes, the European Union is addressing this with the digital product passport, starting with textiles and cosmetics due to their shorter use phases. They have launched an open tender from companies and researchers to develop management systems and a digital platform to preserve, update, and ensure traceability of material data over time. This effort is still ongoing.
2. How are new materials improving construction sustainability? Is it advantageous?
Definitely. In the past, materials lacked regulations for safety and recyclability. Now, new eco-designed materials follow stricter guidelines, focusing on modularity, easy dismantling, and the absence and a transition to safer, more sustainable materials in new construction.
3. What is the most challenging aspect of the Cradle to Cradle certification process?
Certification provides a valuable roadmap for companies, but it’s time-consuming. The challenge, also seen in the circular economy, is needing the right resources and people to collect data and engage with suppliers. This involves data sharing, NDAs, and getting suppliers on board. The process typically takes 10 – 18 months to meet all criteria and requirements.
4. Where can I find more information about all the product passports?
It will take time, as directives approved at the European level require two years for member states to integrate them into national laws, possibly with slight alterations. Anticipate the launch of the first digital product passport around 2027 – 2028, likely beginning with textile products.
