BioBTX is a company in the northern part of the Netherlands creating sustainable BTX (benzene, toluene and xylenes) from non-food biomass and plastic waste. The lower molecular weight aromatics BTX are vital components for the creation of high-performance materials (a.o. new plastics), thereby contributing to the circular transition. In addition, it decouples the plastic industry from fossil resources. BioBTX has a pilot plant (10 kg/h) available and a proven record in the catalytic pyrolysis of end-of-life plastics (e.g. polyolefins) towards BTX. Expanding the feedstock for catalytic pyrolysis towards polyurethanes will not only result in the formation of BTX but most likely also in high-value amines.

In this project BioBTX main task is the optimisation of the chemical recycling processes in collaboration with the University of Groningen. The catalytic pyrolysis of PU will be demonstrated on bench (100 g unit) and pilot scale (10 kg/h).



Circularise enables item-level transparency and traceability by leveraging blockchain (for increased trust) & zero-knowledge cryptography (to protect confidential data). This data can be used to close loops more efficiently. By redesigning future products and supply chains we can make sure that closing the circular supply chain loops is not only possible but also economically interesting. Circularise thereby tackles the obstacles of a lack of digital infrastructure and standardisation and allows data sharing with a validated proof of its validity without sharing sensitive data. It enables data sharing that fully solves the dilemma between transparency and confidentiality. 

In CIRCULAR FOAM Circularise enables the use of private data of companies, their materials, production and further supply chain information without sharing the private data. Circularise therefore provides access to product specific full data of a product, via a question-answer mechanism. This also allows calculations e.g. LCAs and carbon footprint.

Unilin’s division Insulation, with headquarters in Desselgem, started manufacturing roof elements with rigid polyurethane (PU) insulation already in 1973. In 2009 it started production of PIR insulation boards in Desselgem. Today Unilin insulation has manufacturing plants in Belgium, The Netherlands, France, Ireland and UK, and it has become Europe’s second largest producer of insulation boards. Developing a recycling solution for PU-waste is part of Unilin’s strategy, for production, jobsite as well as end of life waste. Because the interests of Unilin as manufacturer of insulation products, and the broader supply chain run parallel, there is a clear added value in sharing the fundamental technological, strategic and systemic research. The capabilities of different manufacturing lines for roof panels and insulation boards will enable Unilin to quickly test production with recycled raw materials on an industrial scale. The relevant product characteristics can be evaluated in our own laboratory. This can reduce development time of products with recycled content.

Unilin Insulation coordinates the work on redesigning and testing existing products to enhance circularity, e.g. by design for disassembly and validate systemic concepts downstream in the value chain. They also evaluate the recycled raw materials from polyurethane recycling pilots of partners in the project and will demonstrate the production of circular polyurethane insulation boards and/or other applications such as roof panels.
