Everyone has to comply with <em>laws</em> and no one is above a law. This included shop owners, managers, and employees, even the President or Mayor of wherever one lives.
Reducing waste in a shop or anywhere for that matter can help eliminate some hazards there might be. The trash can cause mold and that can make someone sick, which just adds another hazard.
A lot of labels can be misleading and not 100% true so ever so a label might say that it's "biodegradable" it might not mean that completely. It might only mean that it's qualified to be that just enough that they don't have to put that it's not. It all depends but I think it's safe to say that it might not exactly mean that it's completely environmentally safe.
