Currently, frameworks for the digital optimization of a building’s End-of-Life (EoL) and its related processes are mainly lacking. This paper explores the digitalization of the EoL process with blockchain technology, by analysing an applied Use Case of a closed loop reuse product in Austria. A blockchain based solution designed to enhance the verifiability of the reuse process is proposed, by introducing a semi-private zero-knowledge proof application which can increase, among other things, transparency and trust to promote Circular Economy."
