The objective of the MUDP-project was to disseminate already existing knowledge on how to design products more resource efficiently through ecodesign; and to engage in a practice-based research to further develop and disseminate methods for resource efficient design. More specifically the project aimed to increase resource efficiency and to convert waste into a resource. Through the examination of four case studies, the current project found that ecodesign tools developed 20-25 years ago are still relevant, waste managers are interested in improved design but are not proactive, and that collaboration between product designers and waste handlers is non-existent. Additionally, this project identifies the role of refurbishment companies as bridge-builders and sees the potential for new business opportunities related to high product quality, durability and reparability in combination with business models such as leasing and product service.
