Russia: The National University of Science and Technology (NUST) MISiS and Vtoraluminprodukt have launched a pilot installation of a bubbling reactor, using the gas flushing principle, in Mtsensk, Oryol Region on 18 December 2018. The concept is intended to fully process industrial waste, slags and sludge, as well as carbon-containing wastes, including municipal solid waste (MSW) and efficient and environmentally-friendly production of iron and concentrate non-ferrous metals. NUST MISiS says that the furnace is the world's only metallurgical furnace capable of processing iron-containing industrial waste as well as solid waste, simultaneously smelting up to 16,000t/yr of metal and producing electricity.

"The advantage of this technology is that it is non-waste and allows for simple, reliable and environmentally-friendly purification of the exhaust gases. And it also allows combining the processing of metallurgical waste, coal preparation factories and municipal waste of enterprises or settlements that are heated with coal. It is a sort of a universal technology," said Nikolay Shenchenko, member of the Expert Mining Committee of the State Duma of the Russian Federation for industry and innovation and the chief executive officer (CEO) of Resmet.

Gennadiy Podgorodetskiy, team leader and director of the Innovative Metallurgical Technology Scientific and Educational Centre, said that the slag composition from the pilot furnace can be selected for further processing into slag stone products, thermal insulation slag or be used to make slag cement products.

Japan: Steel slag production fell by 2.1% year-on-year to 36.7Mt in the financial year that ended in March 2018, according to Japan Metal Daily. This was attributed to increasing levels of slag recycling rates with nearly all of the blast furnace slag being reused.
