The Standardization Plan provides an overview of the current and future standardization activities based on the needs of the REINCARNATE project consortium in the fields of construction and demolition waste to be undertaken during and after the end of the project. This Plan is drafted by Austrian Standards International (ASI) in collaboration with TECHNISCHE UNIVERSITÄT BERLIN (TUB), MOSTOSTAL WARSZAWA SA (MOS), AUSTRALO INTERINNOV MARKETING LAB SL (AUS), VIAS Y CONSTRUCCIONES SA (VIAS), CEMEX, ERASMUS UNIVERSITEIT ROTTERDAM (EUR) and RAGN-SELLS AB (RAS). It provides an overview of the relevant standards identified during the investigation of the standardization landscape and summarizes the priority topics to be addressed within the future standardization activities. It covers topics of wide importance for all spheres of circular economy, Building Information Modelling (BIM), waste management, sustainability in construction and demolition waste (CDW), avoiding CDW in the first place, and being able to reuse CDW in high product quality. Following a Plan-Do-Check-Act methodology, the standardization plan contains focus areas of strategic participation in standardization and a description of actions on how and which standards are implemented in the project.
