Preferred Future Phosphorus Scenarios: A Framework for Meeting Long-term Phosphorus Needs for Global Food Demand

This paper develops probable, possible and preferred long-term scenarios for supply and demand-side measures of phosphorus. The preferred scenarios together demonstrate how substantial reduction in demand for phosphorus can be achieved, and how the remaining demand can be met through high recovery and reuse of organic sources like human and animal excreta (e.g. direct use, struvite crystals), crop residues, food waste and ‘new’ sources like seaweed, ash, bonemeal and some phosphate rock.
