Recycling of Phosphorus from Organic Waste and Residues in Germany
Generally,phosphorus (P) is a limited resource.The non-substitutable nutrient is indispensable especially for the production of fertilizer.The declining quality of mined phosphate rock must be regarded as problematic,because it leads into cost increases in the mining and application of phosphates,and also includes concomitant risks for the environmental and nature protection.Germany does not possess any P-deposits and is,therefore,dependent on imports.The recycling of secondary phosphates from organic waste and residues is a contribution to resource conservation and to the closing of material cycles.The sustainable utilization of phosphorus and the reduction of losses can pave the way for a more efficient,conscientious handling of resources and to guarantee the security of supply for future generations.
