Grassification Project: Biodiversity and Waste Recovery in Kent Verges

Well-managed road verges in Kent support biodiversity and ecosystem services, with 3,000 miles of verges providing habitat for pollinators and native flora. Current practices prioritise safety and cost, often cutting grass at inappropriate times, reducing wildflower seed set and leaving clippings in-situ. The Grassification project proposes a 'cut-and-collect' system to increase cutting frequency to at least twice yearly, timed to support pollinators and seed production. This approach enables biomass to be used for anaerobic digestion or composting, supporting circular economy and net zero goals. The report highlights that verge biomass is classified as controlled waste, complicating energy recovery and environmental benefits. Performance contracting focused on biodiversity, litter management, and energy recovery is recommended, with new funding and monitoring frameworks needed. A PESTLE analysis shows policy momentum from UK climate and net zero commitments, though implementation remains uncertain. Technical and economic challenges exist, particularly around machinery and costs, suggesting mixed management regimes may be necessary for a viable transition.
