The “Association for Liming Fertilisers from Iron and Steel Slags” encompasses all fertiliser-producing steelworks in Germany and Austria. It works on research, development and testing of fertilizers, based on recycling products from steel production and has long experience in vegetation experiments for nutrient research with special emphasis on phosphate and liming fertilisers. Moreover, HKKalke has been engaged in the development of technologies for phosphate recovery from residues and wastes from bone meal and sewage sludge incineration to produce fertilisers with high phosphate efficiency.
Tasks: Responsible for production and delivery of fertilizers, based on industrial waste products (WP01). Contributes to WP05 (Organic Farming) and WP06 (Recycling Fertilizers), by testing the respective fertilizers with respect to nutrient efficiency and environmental characteristics. In WP06, strategies to improve plant nutrient supply from industrial recycling fertilizers by application of bio-effectors are developed, including the investigation of perspectives for fertiliser placement (WP07).
