China's first plasma-based hazardous waste treatment demonstration project approved


The first plasma-based hazardous waste treatment demonstration project in China officially passed acceptance and review by experts on Jan 10, which marks a major technological breakthrough in the solid treatment industry.

CGN's first model project of its kind to be successfully deployed in civil environmental protection, the plasma hazardous waste treatment demonstration project in Qingyuan, South China's Guangdong province, has a designated processing capacity of 100,000 metric tons of waste per day.

Approval signals that the technology can now be applied in the field and heralds a new path for the treatment of hazardous wastes such as medical detritus, household garbage and mineral oil.

The plasma-based hazardous waste treatment uses the extremely high temperatures generated by plasma to quickly crack organic pollutants such as dioxin into small harmless molecules and solidify inorganic waste like heavy metals into a vitreous body, which can be used as a roadbed or building material.

With years of research and development, CGN has self-developed the plasma-based hazardous waste treatment device, and gained about 40 patents based on its technology, one of which was named excellent at the 18th Chinese Patent Award in 2016.

The device can dispose of not only the radioactive waste in the nuclear industry, but also other hazardous materials such as fly ash, electronic waste, and heavy metal sludge.

Targeting medical waste, the Qingyuan demonstration project designed a new production line for plasma-based harmless hazardous waste treatment using modular, automated and standardized equipment.

The CGN Research Institute, a CGN subsidiary, had also signed a contract with a Dongguan-based machinery manufacturing company in 2014 to build a device for plasma-based hazardous waste treatment.

The Qingyuan project has been tested for 168 consecutive hours and now is in trial operation. Its completion and approval was also the debut of the treatment technology in a project.

The technology is considered as answering the national call for environmental protection and the safe disposal of solid waste and garbage.

After the review, the two sides signed another agreement to launch an industrialization base for the technology to promote its commercialization.
