Have to agree with that assessment. One of the major sources of CFCs to the atmosphere was the scrapping of cars with air conditioners without prior recovery of the CFCs in the air conditioner.
However, with regard to "factory" emissions, for a long time the major sources were foam blowing and microchip cleaning.
In any case, using the words "SPEW OUT" is not very scientific. this makes me reluctant to accept what they say.
These two refrigerants were covered with a thin film of water to prevent evaporation and presented minimal flux losses.
