Working with RSK Group company TerrAffix, we have been testing the ability of biochar to reduce the environmental impact of road runoff.
Biochar is a carbon-rich material derived from organic waste. Our laboratory trials replicated potential approaches to treat runoff water, with successful outcomes, demonstrating that even the lowest biochar/filter stone mix was effective at removing microplastics, resulting in significant improvements in runoff water quality.
Following an award-winning laboratory demonstration, we are moving to real world trials within our A417 project to further demonstrate the potential of biochar in this application.
Additionally, the biochar itself sequesters carbon, contributing to carbon footprint reduction. This project not only enhances environmental sustainability but also showcases Kier’s commitment to innovation and incorporating sustainability solutions into our projects.
