WalNUT Project Demonstrates 25% Reduction in Mineral Fertiliser Use with Algae from Dairy Effluents
CIRCULAR ECONOMY & RECYCLING
The WalNUT project showcases a method of producing fertiliser from algae grown on dairy wastewater, which can cut mineral fertiliser use by 25%. Field tests in western France show that mixing algae powder with mineral fertilisers maintains yield levels while reducing reliance on imported resources. The project emphasizes nutrient recovery and sustainable agriculture in Europe.
