Yes, that is a vision I've had for starting a viable business with this and giving a payout to people that bring in plastics/aluminum weigh their collection and pay the current market rate in crypto's. The Alexapure is a ceramic pour filter with extremely small pours so certain size molecules can't make it through from my understanding. I haven't done any analysis such as a total dissolved solids or gas chromatography to verify, but may give that a shot with some connections I have in the future. If you have any suggestions for a test I'd love to give one a shot and publish my findings here on Steemit.
