LIFE No_Waste combined ash from burnt forest residues and organic waste from the pulp and paper industry to revive degraded soil at three former mining sites in Portugal. The team recycled around 50 tonnes of biomass ash and 70 tonnes of biological sludge. The resulting ‘soil improvers’ neutralised soil acidity, increased nutrients for plants to grow, cut toxic elements and reduced soil erosion. The project’s actions also lowered waste from the pulp and paper industry.
