The purpose of the project is to explore information deficits which make it difficult to implement the concept of a more circular anthropogenic metabolism in the construction sector, and to use information tools to highlight ways in which these deficits can be remedied. The provision of information tools is intended to create planning principles for an effective material flow management system for construction materials. An essential element for ensuring the relevance of practice and implementation is the ongoing alignment of the tools with the interests and expected benefits of the people using them, or the user of the information they provide. To ensure that this is the case, the specific engagement with actors in the construction sector is aimed at eliciting their interests, requirements and options – using material passports at construction level, and material inventories at regional level. This process generates information which can be used to help the actors to adopt resource-saving material flow management.
