Abstract

Georgia could serve as a unique natural testing ground for the development of green industry using advanced technologies for industrial processing of hazardous waste. The goal of the reported work was to improve on the current methods of reprocessing waste by using a combination of a microwave enhanced method of processing used tyres and plastic residues with the microwave enhanced processing of manganese bearing waste and low-grade ores into manganese oxide concentrate. The manganese concentrate could be processed into high-grade manganese alloys (metallic manganese, low-carbon ferromanganese, and composite manganese alloys). Microwave heating required lower energy and resulted in a two-fold increase in yield.
