The aim isscientific justification complex method of recycling of phosphorus and sulfur Obsolete pesticides in obtaining useful products and remediation of contaminated soils around chemical composition, resulting in restoration of the natural state of ecosystem functioning and increase environmental security in the region.

In work thecomplex method of recycling of phosphorus pesticides to environmentally friendly products and remediation of contaminated soils. It investigates alkaline hydrolysis of phosphorus pesticide products for example Dymetoat and Zolon and received secondary environmentally friendly useful products. The application of secondary products processing PE class FOS as micronutrients for agricultural products and anti-friction and anti-wear additives for industrial oils.

The resultingdouble salt of phosphoric acid of the general formula NH4MPO4, containing phosphorus, nitrogen, trace elements Zn, Fe, Co, Cu, Mg investigated as fertilizers for cereal crops of wheat, barley and corn. Experimentally found positive properties of synthesized micronutrients for cereals, particularly wheat, barley and corn. Also established patterns of distribution and leakage pesticides near warehouses storing chemicals.

Existingmethods of reclamation and remediation of areas contaminated by pesticides established biological remediation of the best ways of using perennial grasses. The ultimate goal of phitomelioration, reclamation and remediation territories compositions are stable development of the country. In achieving this goal is forecast to achieve the ecological, economic and social effects.

Groundedrisks and environmental and economic performance of the recycling process of phosphorus pesticides. As a result of the proposed integrated method of processing FOS achieved reduction of environmental risks to the environment by 97% and significant environmental and economic benefits. Upon receipt of additive material economic impact is 36 thousand per 1 ton, as if micronutrients is 300 UAH per 1 ton of pesticide.
