Phosphate and organo-mineral fertilizer from waste material

Abstract

Phosphate and organo-mineral fertilizers derived from waste materials have less fluorine than the starting waste materials and are suitable for use in agriculture. Fertilizers derived from two sources of waste materials - tailings sludge from wastewater treatment plants, phosphogypsum and its derivatives, are a contribution that saves natural resources, especially non-renewable phosphorus, and contributes to environmental protection. Phosphate and organo-mineral fertilizers are associated with the industrial processing of phosphate ore, phosphates and salts and their derivatives, wastewater treatment plants and ecological water protection.
