- Scientists are set to use fertiliser made from human urine to cultivate up to 4,500 trees at Bannau Brycheiniog, also known as the Brecon Beacons, in Wales.
- The fertiliser was produced by Bristol-based start-up NPK Recovery, utilising urine collected from 700 attendees at Boomtown Festival in Hampshire last July.
- About 540 litres of the urine-based fertiliser, processed during the 2025 event, will be applied over a three-year project, supported by a £435,627 grant from the Forestry Commission.
- NPK Recovery co-founder Lucy Bell-Reeves confirmed that trials have demonstrated the fertiliser's effectiveness compared to conventional alternatives, with this project marking its first application on trees.
- The initiative, a collaboration with the charity Stump up for Trees, aims to offer a circular solution for revitalising native tree species and advancing sustainable forestry practices.
