Creating fuel from plastic in backyard

Respectfully, I disagree. If we turn plastic into a fuel, there's an incentive to prevent it from being tossed into the ocean in ever-increasing volumes. That alone is pretty goddamn green. But then if it also helps (even temporarily) to lower the amount of fossil fuels being pulled from the ground and burnt by burning what's already so prevalent that it's now part of the sedimentary layering, that is green too. We're simultaneously picking up our trash and subsidizing our fuel consumption. Is it as green as hydroelectricity? Of course not. But it's a net positive, and I can accept that.
