From October 2021 until September 2025, Circularise is participating in the project ‘Systemic expansion of territorial circular ecosystems for end-of-life foam’ (Circular Foam).
Circular Foam is a multi-stakeholder research project focused on improving the circularity of high performance plastics on the example of rigid polyurethane (PU) foams.
Together with 22 leading experts in the industry, Circularise is leading the development of a system for communicating the production process data.
Rigid polyurethane foam (PU foam) is a lightweight insulation material.
It has many benefits. The foam keeps the fridges cold and homes warm. Therefore, it saves energy and limits CO2 emissions.
PU foam, however, is hard to recycle because of the lack of standardisation.
To contribute to addressing this issue, Circularise joined Circular Foam. Circular Foam is an interdisciplinary research project that aims to close the loop in the value chain of PU foam by developing a recycling process.
The project involves the construction and appliance sectors, where the PU foam is used for building and refrigerators respectively.
Circular Foam is led by a polymer company Covestro. Some of the other partners are recycling agency Interzero, a producer of PU insulation boards Unilin, Ruhr Universität Bochum, TU Dortmund, as well as a consultancy agency IZNAB. Interzero works on the dismantling strategy. Unilin is testing alternative recycled materials. TU Dortmund and Ruhr Universitat Bochum provide research into the blueprint to assess the incorporation of the systemic solution. IZNAB is responsible for dissemination activities
See the full list of partners at the end of the webpage.
Under their supervision, all participants are developing and testing technical sustainability-related measures along the PU value chain.
In particular, the project focuses on 5 key objectives:
The project is tested in 3 regions: North Rhine-Westphalia in Germany, Silesia in Poland, and the Greater Amsterdam region in the Netherlands. Based on these pilots, recommendations will be made for the implementation of circular PU foams in Europe.
Circularise is leading the work on the design for circularity.
Using the power of digitalisation, Circularise is expanding the current traceability software to fit the needs of the construction and appliances sector, focusing on the data around the recyclability of PU foam. The enhanced software communicates information to PU foam dismantling and recycling facilities in a reliable and confidential way. Blockchain is used to increase trust, while zero-knowledge cryptography protects confidential data.

Thereby, Circularise ensures that, at the last stage of a value chain, recycling and dismantling facilities possess the necessary material and product characteristics for painless end-of-life treatment.
Circular Foam is an ongoing project. It started in April 2022 and will end in March 2026.
It is estimated that, from 2040 onwards, the project will save
