The construction sector consumes 42 billion tonnes of resources annually, making it the most material-intensive sector. The construction sector also produces about one-third of all global waste, most of which is not recycled or reused, but ends up in landfills. This is a known problem faced by actors across the industry value chain. The collaboration with ROCKWOOL uncovered three key levers to improve circularity: (1) Increase the sourcing of non-virgin and regenerative materials for both raw materials and energy supply; (2) Develop more high-value and circular product applications that can be integrated into modular, adaptive building components; (3) Reclaim more waste from the construction sector through ROCKWOOL’s internal recycling and partnerships with other players.
