Biochar synthesis and functionalisation for highly efficient and selective nutrient (P and N) removal/recovery

This project investigates the conversion of waste conifer brash from Scottish peatland restoration into biochar for sustainable nutrient management. The resulting biochar is evaluated as a low-cost filtration material for capturing and recovering phosphorus and nitrogen from wastewater, with potential reuse as a nutrient-rich soil amendment. The project also explores its application in peatland restoration to reduce nutrient leaching, supporting waste valorisation, resource recovery and the transition towards a circular economy.
