Sustainable infrastructure construction and repair using calcium carbonate waste (CCW) lime – 2021
The ‘Sustainable infrastructure construction and repair using calcium carbonate waste (CCW) lime’ project will investigate the feasibility of the use of lime sourced from calcium carbonate waste as a soil stabiliser. This waste calcium carbonate is sourced from industrial food waste sources such as eggshells and seashells. This will divert food waste from landfill, avoid depletion of limestone and allow the re-use of marginal soils for transport infrastructure.
“This is great opportunity to add value to food wastes and develop them as a raw material resource for the production of lime. This would not only enhance sustainability practices in the construction sector but also provide greater resilience to transport infrastructure”
Dr Ana Heitor, PI.
