In order to reduce environmental and financial costs caused by construction material flow, web platforms have been created. Their objective is to increase the visibility of materials available on construction sites and promote their reuse. A benchmark of existing national and international platforms - considering functional aspects, effectiveness and how the platform interacts with local construction community - has been established by the research team. Strengths and weaknesses of each analyzed platform have been identified, giving an up-todate picture. The benchmark points out, that no “comprehensive“ platform, providing material exchange services as well as support for a large and strong user community, exists. Such a platform could be enhanced by several features – like linking it to geographical information systems and technical assistance, creating a coordinated waste management among construction sites thereby. The Great Geneva Area has been identified as an ideal location to implement the concept and an action plan has been proposed.
