Prospects for the recovery of phosphorus from animal manures: a review

摘要

This paper reviews the potential for phosphorus (P) recovery from animal manures as a method of increasing the sustainability of the global P cycle. The P content of animal manures produced annually in the UK is currently estimated at over 120,000 t. This represents approximately twice the annual non-agricultural P requirement in the UK and has an approximate value of 76 M. Similar quantities of P are produced in manures in the Netherlands and an estimated 600 500 t are produced annually in the US. Up to 65/100 of manure P may be associated with an organic moiety.
