Reboosting resources for more circular construction

The building and construction sector is a major contributor to global climate emissions. At the same time, tonnes of perfectly usable building materials are thrown away every year. To facilitate more circular construction practices, Ragn-Sells has partnered with several property companies to launch Reboost, a reuse initiative for building materials.

– Today, the construction sector has a major environmental and climate impact. This is simply unacceptable. If we are serious about creating a sustainable society, we must transition to circular practices based on reuse and recycling, says Camilla Sonnentheil, Head of Business Development at Ragn-Sells Recycling Sweden.

The construction and operation of buildings account for more than a third of global climate emissions. Yet only a fraction of building materials is reused after demolition, while tonnes of perfectly usable doors, windows, and installations are wasted. To contribute to a more circular construction sector, Ragn-Sells has launched Reboost, a physical hub and an e-commerce platform for reused building materials.

"No one can manage the circular transition alone. By creating a robust infrastructure connecting buyers and sellers, we can close the loop on valuable building materials"

– In order to achieve the necessary volume and efficiency to drive true circularity, we must work together. This hub will make it easier for us and others to access reused materials and prevent valuable resources from being wasted, says Sven Stork, Regional CEO at property company Castellum Stockholm, one of the members of the initiative.

The Reboost hub is a viable business model. The focus has been on enabling efficient circular flows for materials that are in high demand and well suited for reuse.

– One of the major challenges of transitioning to a more circular value chain is managing logistics, such as knowing where to send materials, ensuring sustainable transport, and sourcing reused building materials. The Reboost hub provides the necessary infrastructure to meet these needs, says Anne-Lill Lindholm, Head of Project Management in Construction at property company AMF Fastigheter, another Reboost member.

Reboost is a membership initiative that allows affiliated companies to list, temporarily store, and purchase reused products and materials. Ragn-Sells takes responsibility for assisting with logistics and transportation, and providing advice on reuse and recycling. The purpose is to make sourcing circular materials as easy as possible.

– We see great potential in working with reuse on a larger scale, both in connection with construction projects and tenant adaptations. Being part of the Reboost initiative enables us to strengthen our sustainability efforts and drive change within the industry, says Rasmus Cederborg, Sustainability Coordinator at property company Catena, the latest member to join the hub.
