People aren’t logical beings and there is apparently a market for bottled water, hence there are plastic bottles with water sold. So you expect a brand/company to just disband itself because of an ethical standpoint. Wouldn’t the message die with them?
It has to be said that devoting a third of your bottle’s label to a recycling message is commitment. Suppose this jumps over to big brands with more budget, we might be recycling in no time. And not only water bottles but also other beverages (this also hinges on recycling infrastructure).
Just my 2 cents!
