This is why all the factories are in Taiwan! They aren't afraid to just engineer their way out of the problem and keep advancing.
I can't imagine how long it would take to get this approved in California even if the "wastewater" coming out of the fab and into the treatment plant was already clean enough to mix with infant formula.
If this leads to more environmental friendly production in the long run... i almost hope that the draugh would last longer for even better results...
It would help the situation in the future.
As for ansver above: Super clean, is most likely distilled water. And normal clean water is what you would consider good enough to drink. In this case i am not 100% sure, but that is what most likely is used in here.
