Recycling Agricultural Waste as Fertilizer Explored in Europe

A European project called Circular Agronomics aims to boost nutrient recycling in the agricultural food chain and to help reduce emissions. New European Union legislation that took effect in June made it easier to sell fertilizer made from recycled agricultural products, reports Horizon: The EU Research & Innovation Magazine. As a consequence, researchers with the Nutri2Cycle project are exploring 24 different ways to break down farm waste to make nutrients available as fertilizer, ranging from biodigesters to manure treatment. Waste streams that are being tested for potential as fertilizer include potato processing water, poultry manure, and dairy processing waste.
