MAGMA smelting unit for high-temperature recycling of unsorted municipal waste
Mankind has accumulated and dumped on the earth, an enormous amount of industrial and household waste generated by human activities. Waste has been and continues to be disposed of in dumps, storage sites, deposits and special landfills that cover vast areas.
The problem of efficient processing of most of the above-mentioned waste is solved with the help of MAGMA, which is a cost-effective continuous skull smelting unit, that can process and convert the waste into useful products (metals, construction materials, thermal power and electricity) by waste-free and environmentally clean technologies.
The multi-purpose smelting unit MAGMA provides autogenous process of high-temperature recycling of unsorted municipal waste on a layer of molten over-heated slag that forms from the mineral components of waste and fluxes that are specially added in the process of recycling.
MAGMA smelter uses liquid sodium as a coolant, which is a proprietary technology of Russia and used in the Nuclear Reactors & Nuclear Submarines in the last 30 years. As compared to water, liquid sodium is 90 times more efficient.
In MAGMA, temperature of the working space of the smelting chamber over the layer of molten slag is 1,800-1,900°C & the temperature of slag is 1,400-1,650°C. Under such conditions, the smelting chamber produces a ‘thermal shock’, under which the fed waste immediately heats up to high temperatures that rule out the possibility of the formation of dioxins.
In MAGMA, gases stay at 1,850°C for 3 seconds. Under such conditions, almost 100% destruction of dioxins & furans is ensured. These toxic elements are carcinogenic even at nanogram levels and can reach the human body through ground water & air. None of the existing technologies can destroy them completely.
Production figures of high-temperature recycling of municipal waste in MAGMA unit –
| Output products | Unit per ton of waste | Amount |
| Electric power | MWh/ton | 0.40-0.50 |
| Iron alloy | kg/ton | 5-30 |
| Slag-cast products / construction materials / rock wool fibers | kg/ton | 250-300 |
Investment on the MAGMA project can be recovered in 3-5 years, depending on the plant capacity. MAGMA can meet the objectives of the 21st century, as a clean & efficient municipal waste processing technology.
