Wow, great initiative. I think this is a perfect example of the market solving the problem fast. My main question is, how are you thinking about emissions and waste? Presumably, you've got to melt and extrude these things somewhere, and heating the plastic to its melting point to create decent sized quantities of this will result in harmful emissions of some kind. Do you have some sort of a scrubbing system? If so, how did you figure out what kind of system to set up and right size it for your production capacity?
