Came here to say the same. Love seeing waste industry stuff at HN :)

Prairie Robotics (and similar) is another interesting take on the problem at the industrial scale. They are recognizing contamination as the waste is collected so the generators (houses/businesses) can be notified and educated.

Never heard of Prairie Robotics but I was curious if they had anything to do with where I live since I'm in a prairie province. Turns out their corporate HQ is in my city!
