It will require someone like LEGO (others) to fully adopt it and prove its effectiveness, and for the governments to mandate its usage while providing incentives for adoption. However, the plastics industry will likely resist this change strongly. There’s also the issue of monoculture, the ideal is reduction (such as re-use durable cotton bags) — I wonder if plastics bags disappeared overnight wouldn’t people adapt? Probably a few extra trips to the supermarket at the start but shortly after a reusable container wouldn’t be forgotten. There’s more to plastics pollution than plastic bags though, water bottles, fast fashion and synthetic fibers, etc.
