2016-2017: Re-Engineering Business for Sustainability (REBUS)

The Re-Engineering Business for Sustainability (REBUS) research project was funded by DEFRA, and aimed to explore and develop ways to increase the useful life of products which all too often go to landfill well before they have reached the end of their useful; lives. It experimented with the use of a Product Service System (PSS) based approach to the supply of car seats, and was carried out by researchers at the University of Hertfordshire, collaborating with Dorel (manufacturer of Maxi-Cosy car seats) and the National Childbirth Trust (NCT), with nearly 400 users being recruited in the pilot.

AERU was contacted due to their experience in life cycle assessment (LCA), and examined the environmental implications of the PPS system when compared to a traditional buy-use-dispose system. This included all the materials and transport involved in both systems and was intended to inform a more informed debate about the potential merits of such a system.
