Clean Tech Delta is a cluster of universities, knowledge institutions, cities and companies in the Delft-Rotterdam-Drechtsteden region. We strive to initiate cleantech initiatives, support companies and projects and promote cleantech opportunities. The knowledge developed during this project will be highly relevant to Clean Tech Delta, to disseminate within organizations active in the field of waste, to learn from and share best practices. Our focus topic is circular economy and the lessons from this project will be relevant for innovators, companies and governments in our network. When we see opportunities for the project, we share our ideas with the consortium.
