After seeing this, I now always think twice about single-use plastics like water bottles and grocery bags.
No that doesn't make sense. If they didn't care about recycling why would they make people sort their trash in the first place?
At least in EU, companies can get generous grants for recycling, but there's little oversight, so often "recycling" part is only on paper or small part of total waste. Few years ago there was scandal in Lithuania, because thrash companies put different containers for plastics, glass, organics etc. but everything was collected by the same truck and mixed in the same trunk.
However, I seriously doubt they throw recycling into trash. There are a lot of people who would see this and among them I bet one or two would care enough to snap a picture which I suspect would make the company lose municipal contracts in a flash (and get slapped with a hefty fine).
I do not think they care that much about the environment, but with the current attention to the recycling issues throwing recycling into trash seems just very bad business -- high risk, very high cost.
