We asked three companies to recycle plastic and only one did
There is nothing wrong with landfill or incineration. Unlike metals, recycling plastic is not economic. So converting it to  energy by incineration is a pretty good option. In the future if the oil supplies will dwindle it might be economically viable to recycle plastic and then people (or maybe robots) will excavate those landfills for material. It is us taking care of the future generations. Isn't it what all those Gertas of the world want?
