The design and development of a digital platform is usually highly complex and involves many individual steps in preparation. Within the scope of the research project PERMA (Platform for efficient resource utilization in the furniture and furnishing industry) a digital platform is developed to promote circular economy core mechanism in the furniture and furnishing industry. The aim of these core mechanisms is to establish an overarching platform that covers processes and involved stakeholders from primary use (purchasing/renting/leasing), secondary use (processing or upcycling) until end of life (EoL) (recycling, refurbish, reuse etc.). This paper gives an overview on the identified circular economy core elements and stakeholder needed as well as barriers and drivers and a design approach to develop processes to enable circular economy features on a digital platform. Within the paper the developed design approach will be presented and the identified main processes for the PERMA platform will be described. Lastly, final considerations are presented with the identification of new research streams, including the need of the evaluation of these processes in other sectors to implement CE platforms and the potential to collect cross-sectoral platform use cases that are successfully mastering CE best practices.
