Biography: Andrey Norov
IntherecentyearsJSC “The Research Institute for Fertilizers and Insecto-Fungicides Named after Professor Y. Samoilov” (JSC “NIUIF”), the oldest (established in September 1919)industry-orientedinstituteinRussiahas developed a range of sustainable, environment-friendly, zero-wastetechnologies, that ensure minimal consumption of materials and energy resources and fully consistent with the principles of Green Chemistry that include:Environmentally friendly energy and resource saving technology of sulfuric acid from sulfur according to DC-DA scheme (double conversion - double absorption) Improved zero-waste technology of wet phosphoric acid (WPA) by dihydrate-hemihydrate processapplicable to various types of phosphate raw materials [2,3]Flexible, efficient, zero-waste, universal technology of NP / NPS / NPK / NPKS fertilizers with maximum utilization of heat from chemical processes An innovative, zero-waste, no-analogue technology of granular PK / PKS NPKS fertilizers with controlled dissolution rate and nutrient supply into the soil solution, which allows to process a number of wastes and by-products;An innovative resource-saving joint processing of wastes from production of phosphogypsum and fluorosilicic acid (FSA) into ammonium sulfate with simultaneous neutralization of fluoride compounds without using lime.All listed green technologies are protected by Russian and Eurasian patents.The development of environment-friendly, safe, green technologies is ongoing in JSC “NIUIF”.
