Product traceability through DPPs in PU foam recycling
Through the development of digital product passports (DPPs), Circularise is advancing product traceability in the Circular Foam project, which aims to revolutionize rigid polyurethane (PU) foam recycling.

Circularise uses digital product passports to advance product traceability.
Circular Foam project
The Circular Foam initiative is critical in advancing the circularity of this material, with a focus on creating systemic, territorial approaches for efficient recycling.
The Circular Foam project’s environmental impact is significant. By 2040, the project is estimated to prevent 1 million tons of waste, reduce 2.9 million tons of CO2 emissions, and save 150 million euros in incineration costs.
Circularise is helping to test and refine solutions for large-scale implementation of circular PU foam recycling in order to formulate recommendations for scaling the solution throughout Europe.
Circularise DPPs
Circularise has successfully created DPPs for key products, including an Electrolux refrigerator door, a Unilin insulation board, and a Kingspan metal panel.
These DPPs capture vital data about product composition, sustainability certifications, and end-of-life (EoL) processes, providing key information for recyclers and consumers. This level of traceability has empowered recycling companies to access critical material and product data, allowing for more efficient recycling processes and higher recovery rates.
DPPs in Circular Foam project
In the Circular Foam project, Circularise’s platform can share confidential company data securely.
The platform uses blockchain technology and zero-knowledge cryptography to ensure that sensitive information, such as proprietary chemical compositions, is protected while still allowing companies to share essential details with the necessary stakeholders. This has set a new standard for data transparency and collaboration within the recycling industry.
For consumers, Circularise provides public-facing Digital Product Passports (pDPPs) that includes information about a product’s lifecycle, from material composition to environmental impact.
This feature enables environmentally conscious consumers to make informed purchasing decisions and supports the growing demand for transparency in sustainability.
Having finalized the work on DPPs and pDPPs in the Circular Foam Project, Circularise plans to extend its platform to other materials and industries, driving the global transition to a circular economy and advancing recycling practices across various sectors.
