Such a ban on single-use plastics came into effect last year in India. As they say "devil is in the details" , there were a bunch of criteria defined for the ban. Eg material for carrybags, thickness for some items & so on. Immediately, everywhere the polythene bags are replaced by poly-something-else bags . (Polystyrene?) . And the items which were banned based on micron thickness, were replaced by items which are one micron thicker than that limit . The one-time-use factor did not change a bit. Instead of that older material, we're now throwing newer / different / thicker material.

It is still plastic, non-biodegradable, single-use, garbage.

Sad.

Watch out how Canada does.
