To effectively tackle the end-treatment bottleneck of MSW incineration and drive the technology advancement of fly ash pollution control, China Tianying has actively developed the plasma melting technology that uses high temperature plasmas to completely destroy persistent toxic organics such as dioxins and furans in the fly ash. In addition to achieving a completely harmless disposal, the process generates a vitrified glassy matter which can be used as construction material for roads and buildings. The flue gas can be separated and prepared to produce industrial salts, closing the loop of fly ash treatment and resource recovery.

This technology can effectively help resolve issues related to the limited storage capacity of landfills or sanitary landfills in developed areas.

We have independently developed the plasma gasification and melting process, covering medical waste transfer and sterilisation, plasma gasification and melting, flue gas purification and wastewater treatment. The flue gas emission reaches the EU standard (EU Industrial Emission Directive 2010-75-EC), and the glassy matter formed by ash residue is reused for other purposes. The core equipment, such as plasma torch and melting furnace, are self-manufactured with world-leading configuration and performance. Our high-power plasma torch, adjustable between 50-300kW, can satisfy treatment needs of various scales.

In 2020, the technology passed the technical evaluation of a 9-member expert panel chaired by the Hai'an People's Government and headed by Mr. Li Yinghong, an academician of the Chinese Academy of Sciences, with a conclusive decision that the technology process is reasonable and feasible, reaching international advanced level, and can be applied to the treatment of medical waste larger than 10t/d. The emission of pollutants meets both China GB18484 and EU 2010 standards; organic wastes containing chlorine are treated with very low level of dioxin emission.
