More than 22 million tons of ammonia are lost from livestock farms around the world every year. Lost ammonia means lost fertilizer and is a waste of nutrients and an economic burden for the farmer. The farmer needs to replenish lost nutrients through purchase of expensive, fossil-fuel based nitrogen fertilizer. Today’s industrial fertilizer value chain is costly and harmful to the environment.

ArcFume is a metallurgical plasma based process for treatment of complex industrial waste. With a high yield, it recovers valuable metals as zinc, lead, silver, copper, germanium and indium. Handling of by-products is an important step for metal smelters towards higher metal yield and less waste. By introducing the plasma based ArcFume process, they are moving towards electrification of the process flow sheet.

Fly ash generated from municipal solid waste incineration is in most cases classified as Hazardous Waste and poses an environmental risk. Today, landfill is the common method to handle the waste while countries are looking for more sustainable solutions for the future.  ScanArc metallurgical process ArcFume is a plasma based treatment method that can turn the fly ash from waste to value.

About 20% of the CO2-emissions in the steel industry can be ascribed to furnace heating processes. The industry estimates that a large share of the furnaces can be electrified to reduce the use of fossil fuels, and one solution is electrification with plasma technology. Using plasma heating, the steel industry will have cost-effective solutions and a faster transition towards green technology.

Manufacturing of cement, ceramics and minerals are a major environmental concern. Cement production accounts for 3-5% of global carbon dioxide emissions. One step in process is to heat up limestone to 1450 °C to release carbon dioxide. Carbon dioxide emissions come partly from this process, but also from the fuel required to heat the furnaces.

Gas heated to high temperatures by ScanArc´s plasma technology can be used to crack different hydrocarbon chains oftentimes present in the industrial off gases. Using plasma technology could be an environmentally friendly approach for such an off-gas treatment.
