According to an announcement from Russia’s National University of Science and Technology MISIS, the bubbling reactor furnace is capable of recovering 16,000 tons of metal per year from industrial slag and sludge as well as from household wastes. 

The furnace employs the gas-flushing principle, a technique to remove dissolved gases in a liquid by bubbling a gas through the liquid. 

"Due to the unique design of the unit, energy costs can be brought to 500 kg of coal and 500 nm of oxygen per 1 ton of cast iron. As a result, we recycle industry waste, get cast iron, commercial slag and non-ferrous metal concentrate. There is no waste in our technology. The pilot sample is also designed to test the technology of waste-free gasification of numerous carbon-containing waste, including solid domestic waste," said Gennadiy Podgorodetskiy, the furnace's developer and director of the university's Innovative Metallurgical Technology Scientific and Educational Center.
