This website aims to provide an information
platform on the recycling of phosphates.
Why ? Because closing the phosphate cycle
reduces consumption of phosphate rock resources and reduces energy consumption
(greenhouse gas emissions). read more
What ? Phosphate is present in sewage (from
human urine and excrement, food wastes, detergents …), animal wastes, and
certain industrial waste streams (metallurgy, food industry …). read more
How ? Phosphate can be recycled by many
routes: by using animal wastes or sewage biosolids to fertiliser agricultural
land, use of sewage nutrients in biomass production, use of sewage sludge
incineration ash as a raw material in the phosphate industry, precipitation of
phosphates in sewage works or animal treatment (as struvite, calcium phosphates
…) read more
Where ? A majority of phosphates in sewage
and animal wastes worldwide is already recycled through agricultural use of
biosolids, but this is not feasible where waste streams exceed agricultural
needs (intensive animal production, large cities, urban areas). A number of
phosphate recovery installations are operational recycling phosphate from
sewage into industry or as a mineral fertiliser.
A wider development off P-recovery will
require a combined movement of R&D and process development, water industry
involvement and regulator pressure.
This
website aims to provide an information basis for this development of phosphorus
recycling, necessary for sustainable development.
