Abstract
Phosphorus recovery from waste - methods review According to sustainable development principles, searching for alternative phosphorus sources, especially possible ways of its recycling from waste, should be treated as a preferential problem of the phosphorus industry. The ways admitted as most important are: - phosphorus recovery from municipal and industrial sewage and from sewage sludge, - utilization of phosphorus from manure - management of waste from meat industry The forecasts elaborated at the end of the last century, indicate that over 50% of the world phosphorus resources in use today will be depleted during the next 60 - 70 years. That fact contributes to increase of market prices of phosphorus products. This work presents possible directions for the recovery and management of sewage sludge, meat meal and manure as a phosphorus source for chemical industry.
Highlights
In compliance with cleaner production rules, waste should be treated as the potential source for the manufacture of new and valuable products
Civilization development is connected with generation of continuously growing quantities of waste
According to European Union priorities in the field of waste management it is advisable to undertake the studies aimed at reducing the quantities of stored waste and utilization of its component[11]
Summary
In compliance with cleaner production rules, waste should be treated as the potential source for the manufacture of new and valuable products. Sewage sludge from municipal sewage treatment as well as waste from animal production and meat industry are potential sources of phosphorus compounds and should be given as an example[1]. According to sustainable development principles, searching for alternative phosphorus sources, especially possible ways of its recycling from waste, should be treated as a preferential problem of phosphorus industry
