Swiss Water Method & Water Efficiency
I've heard along the grape vine, that out of all the companies that utilise the Swiss Water Method to decaffeinate their beans, only 5% of companies actually recycle their water to be used again in the process. That overall, for every 1kg of decaf 10L's of water is used. Therefore, although a preferred method for 'health' reasons it potentially has a gross misuse of a natural resource if not recycled.
Also, the used water can potentially have negative effects on the surrounding soil when discarded...
I had been told this by someone who knows quite a bit in the industry, however, have been unable to source any validity to the above statements. Does anyone have information that supports or squashes these claims???
There's only one company utilizing the Swiss Water Process as far as I know and that's Swiss Water in Vancouver, Canada and there the GCE (green coffee extract) infused water is used over and over again, batch after batch, removing caffeine while re-infusing green coffee extract.
