I think that the focus on technological solutions is beside the point. What would accelerate reduction in use and an increase in recycling would be a total ban on exports of used plastic and a ban on packaging plastic from non-renewable sources. This should also cover clothing. The technology required can be left to the industry once it becomes impossible for them to hand off the responsibility to foreign and unregulated third parties.
