U.S. startechenvironmentalcorp:startechenvironmentalcorp, a listed company and recognized award-winning environment and energy company in 2008. (otcbulletinboard:sthk) in the UK and the Republic of Poland, the distributor waste2greenergy (hereinafter referred to as "w2ge") installed its first plasma converter system in a designated factory in bitom, Poland, which can handle 10 tons of industrial waste per day.

Korean Institute of nuclear environmental technology:the Korean Institute of atomic energy, located in Daejeon, South Korea, has built melter equipment for the treatment of low-level radioactive waste. The equipment can not only deal with radioactive soil, metal and concrete, but also does not need to classify and compress waste.

British advancedplasma power (APP) Company plasma gasification technology:British app company has built an RDF processing plant in Swindon, with a daily processing capacity of 2.4t. The device adopts two-stage plasma gasification technology.

British tetronics plasma gasification technology:tetronics plasma is a plasma technology supplier funded by the British iron and steel and Coal Research Council. Its DC plasma technology has been used in many industrial fields, and the most successful is the recovery of precious metals. Since 1989, tetronics has used DC plasma smelting technology to recover nickel, chromium, manganese, iron and other metals from 8000-23000 tons of stainless steel dust every year. In addition, it also uses this technology to recover platinum group metals from 1000-3000 tons of automotive and industrial catalysts every year. The metal recovery device developed by tetronics company can treat a variety of powdery wastes together without briquetting. The variability of reaction conditions and furnace temperature converts the wastes into slag and metal products, which maximizes the recovery value of wastes, minimizes secondary wastes, and realizes low air and water emissions.

Plasma gasification technology of europlasma company of France:europlasma company has built a demonstration plasma waste treatment device in France using Cho power multi-stage gasification process. The process adopts non transfer arc plasma torch. The device is mainly designed to treat industrial waste and biomass. The plant has been in operation in November 2015.

Plasma gasification technology of Israel environmental energy company: Israel environmental energy company built a pilot scale plasma gasification melting (PGM) plant in northern Israel in 2007, and equipped with corresponding equipment to make it operate commercially. The company then cooperated with envitech in San Diego to provide a good treatment method for the growing medical waste by using PGM technology, and envitech's air pollution control system is used for the clean treatment of exhaust gas, so as to realize the safe discharge of exhaust gas. Est company in Israel provides environmental friendly waste treatment systems for various organic industrial wastes.

Bellwether plasma gasification technology in Germany:bellwether established a 12t/h plasma waste treatment plant in Romania in 2007, which is mainly used for the treatment of urban domestic waste and industrial waste, and can achieve 80% - 85% gasification efficiency. The syngas produced in the gasification process is transported to the local power plant, which can replace 28000t of coal, Greatly alleviated the local energy crisis.

Indian Institute of mines and technology:apply plasma technology to the treatment of red mud waste.

Taiwan Institute of plasma gasification technology:Taiwan Institute of plasma gasification technology: Taiwan Institute of nuclear energy began to develop plasma torches by itself in 1993. After breaking through this key technology, a 100kW non transfer arc plasma torch device was developed in 1996.
