Waste

In 2017 we:

• Reduced construction waste relative to project turnover by 11% compared with 2016, and by 56%, compared with our baseline year of 2012
• Diverted 97% of non-hazardous construction waste from landfill

Construction waste per £100k of project turnover

Between 2016 and 2017 we reduced construction waste intensity by 11% - and since 2012, the baseline for our 60% reduction target, by 56%. This means that we are well on the way to our 2020 target.

Progress has been achieved through a range of interventions, including:

• workshops to look at how to prevent waste through smarter design
• use of a waste prediction tool to provide a more accurate forecast of waste based on previous projects
• working with manufacturers and suppliers to design out waste
• use of incentives to encourage collaboration with supply chain partners to reduce waste
• an increased focus on off-site fabrication
• real-time analysis of project waste data to address issues early

Waste diverted from landfill (non-hazardous construction waste only)

In 2017 we developed a tool which enabled our preconstruction teams to more accurately calculate the amount of waste a project will produce, based on data collected from previous projects. This tool is now helping us design out waste before the project even goes on site.
