Yesterday I posted on /r/crazyideas about doing a startup that would design reusable, standard packaging of difference shapes for all possible food forms. It could be made of high quality plastic, glass, maybe stainless steel, etc as long as it can be easily recycled and that brands can put paper stickers on them. Those can be returned/sold back.

Someone answered me that most plastics can be recycled because he worked in a recycling plant, meaning this was a bad idea. I linked him a forbes article after a few comments and he stopped answering. It's hard to know if that guy was just astroturfing me.
