Worked in a small event managing company (planning, gear, etc). It produces so much waste in a week that a typical 10 floor 10 staircases living building house wouldn't in 2 months. There are much more and bigger companies. I can only speculate how much waste they produce.
This is only a microscopic part of all businesses in our city. Production lines, grocery stores, commercial buildings must be producing thousands of tonnes more. I doubt that all of the households in town produce as much as all the companies combined. We are not the problem.
