The worst recycling is better than the best mining.

Sustainability means improving recycling, making it more efficient. Usually, that means enforcing against the worst actors, not restricting trade to the best actors, or giving stimulus to reward early adaptation of better practices.
By the way, grinding up CRT glass and mixing it into concrete is not exactly recycling (we call it "Jimmy Hoffa recycling"). The famous TCLP test is for safe disposal in an lined Subtitle D landfill, it is NOT a permit for putting stuff into concrete. Concrete really doesn't last as many generations as people think it does, and putting lead and barium into the concrete is not really any better an idea than putting it into paint.
