HCFC – THE OZONE DEPLETING GAS
What is HCFCs?
HCFC (hydrochlorofluorocarbon) is a chlorine-based refrigerant that cause ozone depletion – the shield protects the earth against harmful UV rays from the sun.
HCFC, commonly called R-22 in Vietnam, was used in many older air conditioners.
The treatment of HCFCs reduces the leading cause of ozone depletion, which plays a key role in restoring the ozone layer – the Earth’s shield.
The collection and treatment of HCFCs is part of a project to build a green hospital sponsored by the Mitsubishi Corporation under the framework of cooperation between the two Governments of Vietnam and Japan. It is expected that by 2030, Vietnam will handle 97.5% of the ozone depleted emissions in air conditioners and old refrigerators.
Under the supervision and support of the Ministry of Natural Resources and Environment, the Ministry of Industry and Trade, the Green Development Center and Japanese experts, more than 123 kg of HCFCs are put into cement kilns at temperature of above 2,000°C, long burning time, and a closed feeding system for complete destruction. INSEE Ecocycle Vietnam is proud to be the pioneer in processing HCFCs by Co-processing technology.
This HCFC is taken from the air-conditioners of the two hospitals of Viet Duc Friendship Hospital and the People’s Hospital 115, under the project “Building the green hospitals through the improvement of effective & environmentally friendly energy use in Vietnam” under the cooperation between the Government of Vietnam and Japan.
Nearly 20 prestigious press agencies across the country simultaneously reported on the event, such as:

Process of HCFC treatment in INSEE Ecocycle Vietnam
INSEE Ecocycle Vietnam has detailed plans for all steps from analysis, testing and transportation to co-processing in cement kiln. Experts handling waste are trained and equipped with the necessary protection to ensure that all operations with waste are safe. Risk assessments are communicated to workers and staff in a clear and timely manner. Prevention and controlling measures of fire, explosion and explosion are always available.
Collection and transportation
The HCFC tanks were visually risk-assessed, wrapped around by foam to avoid collisions and contained in secondary containers which were also fixed by the straps. In addition, the GPS system keeps track of it from pick-up to transportation stage to the factory.
Treating HCFC thoroughly & safely by Co-processing in cement kiln system
Cement kiln with high thermal capacity up to 2.000*C, long residence time, high oxidation environment together with closed feeding system, are monitored continuously for complete destruction of HCFC compounds. Co-processing is recognized as a feasible, efficient and environmentally friendly solution for the general disposal of waste in the world and is supported by international organizations such as the World Health Organization (WHO), the Business Council The World of Sustainable Development, Basel Convention, European Cement Association.
The exhausted gas is controlled by a 24/7 continuous emission control system to ensure overall waste disposal, specially HCFC, does not cause any environmental impact and ensures compliance with requirements according to environmental legislation of Vietnam & the highest standards of corporation.
It can be said that the event of successfully co-processing HCFCs is a big turning point in protecting the ozone layer in Vietnam, contributing to raise awareness of people, especially enterprises, to jointly fight against the climate change.
