Efficient Carbon, Nitrogen and Phosphorus cycling in the European Agri-food System and Related Up- and Down-stream Processes to Mitigate Emissions (Circular Agronomics)

Recycling of phosphorus, nitrogen and carbon

Due to the increasing depletion of the resource phosphorus and the global warming, the project Circular Agronomics aims to promote an efficient carbon and nutrient cycling with a special focus on the mitigation of greenhouse gas and ammonia emissions.

Circular Agronomics is coordinated by the Spanish partner IRTA and unites 18 partners from Kenia and 9 European countries as well as 27 associated partners from the industry, small and medium-sized enterprises, local authorities and research institutes. At six sites in Spain, Germany, Austria, Italy, the Netherlands and Czech Republic, innovative technologies for nutrient valorization and its reuse in agriculture are investigated. Especially, the interaction between plants and soil are analyzed. Furthermore, the technologies are assessed socially and economically.

The Berlin Centre of Competence for Water (KWB) is responsible for the lead of the work package “carbon and nutrient valorization from food-waste and food-processing-waste(water)” and reviews the “best available techniques” regarding nutrient valorization. In addition, investigations in a vacuum degasification plant for the recovery of nitrogen are accomplished as well as life cycle assessments for the nutrient valorization. For the dissemination and exploitation of the results, KWB will organize simulation games with different actors and conduct concept studies for interested biogas plant operators.



Selected publications produced in the Circular Agronomics project are available here.
