A Circular Economy is as one where materials are retained in use at their highest value for as long as possible and are then reused or recycled, leaving a minimum of residual waste.
The built environment sector is the largest user of materials globally. In London it consumes 400 million tonnes of material each year and accounts for 48 per cent of waste (source: LWARB Route map). Extending the life of buildings and recovering and reusing materials at the end of their life can help reduce the demand for materials and waste produced.
Adopting circular economy approaches will play a significant role in promoting resource efficiency and addressing the challenge of the climate emergency. A transition to circular economy is also important in London becoming 100% net self-sufficient in managing its own waste.
A 'Designing for Circularity Primer' has also been written to help support organisations in the built environment sector to understand how they can embed circular economy principles into their projects and design processes.
