The LDE Centre for Sustainability is a multidisciplinary Research, Education and Valorisation Centre in which three Dutch Universities join forces: Leiden University, Delft University of Technology and Erasmus University Rotterdam. This enables us to actively build bridges between science and society by working together on the challenges and opportunities surrounding the transition towards a Circular Economy. We aim to provide research-based solutions for enhanced resource efficiency taking into consideration the entire product lifecycle, based on 4 shared research areas: 1. Industrial Ecology and Economics 2. Circular Business Models and Product Design 3. Clean technology for Resource Efficiency 4. Governance, Regulations and Transitions Hereby, we actively involve companies, NGO’s and governments in formulating the societal challenges to be solved. Together with committed stakeholders we will effectively create 'Roadmaps' surrounding different themes and apply results and share outcomes with society - in order to achieve sustainable resources for a growing world population. Led by scientific staff from all three LDE Universities, our (research) activities will include MSc. Students, PhD’s and Post Docs ensuring a strong research line over the years. Collaboration between all stakeholders is crucial to make sure that results are valuable, knowledge will be disseminated and circular innovation will take place.
