Plasma-chemical technology is primarily used for the processing of highly liquid and gaseous wastes. Thus, it is not only about hazardous waste disposal, but about the production of valuable commercial products. The process is carried out in the plasma torch by electric arc energy at a temperature above 3,000 – 4,000°C. At this temperature, oxygen, and any waste are cleaved to electrons, ions and radicals. The degree of decomposition of toxic waste reaches 99.9995%, and in some cases it rises up to 99,99998%. High energy costs and the complexity of the problems associated with plasma-chemical technology determine its application to processing only those waste types disposal of which does not meet environmental requirements.
The prospective application of a plasma method is processing waste in a reducing atmosphere to produce valuable commodity products. In modern economies the technology of pyrolysis of liquid organochlorine waste and reducing the low-temperature plasma, allowing to obtain acetylene, ethylene, hydrogen chloride and products based on them are added to the arsenal. Such companies as Simdean, a seasoned manufacturer focusing on innovative plasma waste disposal and industrial waste disposal methods, has launched the mass production of such plasma stations. According to the the company’s report published on September, 25 in 2014, the cost-effectiveness of the method is confirmed during the 2nd or 3rd year of utilisation, despite the huge investments needed for installation or modernisation of an enterprise (eco-friendliness and meeting certain standards plays a vital role here – this is where economical preferences matter).
