Technologies for realizing a circular economy of CFCs

Technology / Service Summary

Even among the general simple distillation type, we have made it even more energy efficient and compact to reduce the environmental load.


While the natural refrigerants currently in use are not a little dangerous, by regenerating and recycling the existing Freon gas without releasing it into the atmosphere, we can prevent global warming and utilize the current refrigeration and air conditioning equipment.


By switching the method of treating CFCs from destruction to regeneration, we will take measures to address the shortage of HFCs and contribute to the construction of a recycling-oriented economy. In addition, we commissioned Chukyo Fluorocarbon Co., Ltd. to develop and succeeded in developing and commercializing a regeneration device that can regenerate fluorocarbon with a single compact refrigerator. Our strength is that we can use energy-saving and economical equipment.

Furthermore, we have introduced reusable containers for the sale of recycled CFCs. This also reduces waste.


By improving the piping structure to properly control the flow of Freon gas, properly remove impurities from Freon gas, and downsizing the entire device, the energy required for the regeneration device is only about the power of one air conditioner (15A).
