Recycled aggregates, TfL trial

The construction industry is facing increasing pressure from policymakers to become more resource efficient due to it being both the UK’s largest industrial producer of waste and largest consumer of natural resources. According to the UK Green Building Council, the sector uses more than 400 million tonnes of material every year and both the EU’s Circular Economy Package and the London Circular Economy Route Map (a scheme led by the London Waste and Recycling Board) highlight that construction’s support is critical to making the shift to a circular economy – a concept which aims to maximise the lifecycle of resources as much as possible.
