«Green» technologies in metallurgical production – a dream or reality?

Abstract

The paper analyzes the existing technologies of metallurgical production with minimal harmful effects on the environment. Emissions of carbon dioxide into the atmosphere can be eliminated using hydrogen as a reducing agent with iron oxide. The best results are realized when hydrogen is produced by electrolysis of water, but such technologies require serious investments. More realistic in terms of creating “green” technologies in metallurgical production is to reduce the consumption of natural gas, capture waste gases of metallurgical production and use them to produce electricity and new types of products: methanol, synthetic alcohol, fertilizers and polymers. An integral part of “green” technologies is also the implementation of the NoWASTE concept, aimed at minimizing waste to be disposed of. Examples of non‑waste technologies for the processing of aluminum waste at OOO NPF Metallon are given.
