Japanese researchers take another step in the fight against CFCs. The Osaka Research Center has developed a new technology for the elimination of greenhouse substances, which will be put on the market soon.

In 1987, States pledged in Montreal to reduce the use of CFCs and the damage caused by it. As we know, not everyone has fulfilled the word given. In any case, the accumulation and elimination of CFCs is a political and technical problem. CFCs should be stored and treated at high temperatures, which means a high cost.

The new technology used by Japanese researchers has solved this problem. Decomposition of CFCs by ultrasound at the Osaka research center. The atoms of this substance were immersed in the water and attacked by ultrasonic rays imperceptible by the human being. In this way, the effect obtained at high temperatures and using ionized gases, that is, the elimination of CFCs, was renewed.
