The project was funded and implemented by Eco-eye Co., Ltd, based in Seoul (Korea). Currently, waste refrigerant is discharged directly into the atmosphere, and it greatly affects the ozone layer, making a significant contribution to global warming. F-gas is widely used in refrigeration equipment in cars, air conditioners, refrigerators, and refrigeration equipment in the industry, and buildings. One molecule of Fgas causes a greenhouse effect of 1,300 – 8,500 times higher than carbon dioxide (CO2). In Vietnam, the project is jointly implemented by Eco-eye, the Investment and Trade Consulting Company Limited (INTRACO), VNCPC and OunR2tech Co., Ltd. in the period 2020 – 2023.
