In this project, a consortium consisting of five chain partners (Sustan, Code Product Solutions, Transmare Compounding, Kupron and Vista College) wants to develop circular green walls made of natural fibre reinforced PMD recyclate (a composite material). In addition, the goal is to ensure circularity after the lifetime, during the End of Life (EoL) phase, through the development of a product passport and tracer compounds, in order to actually enable circular processing. These green walls can be used for the greening of homes and apartment buildings, both indoors and outdoors, which is beneficial for the climate transition. Through the chain-wide cooperation of (South) Limburg parties, the consortium is also committed to realizing a regional value chain and strengthening the regional economy.
