I feel your pain on this - please keep up the good fight.
FWIW, the recycling at my company is pathetic, even though we have great facilities that make it very easy for employees to recycle.
On a daily basis, I am constantly picking plastics, food waste etc. out of the paper recycling bin, picking paper towels out of the jars and cans recycling bin, and correcting other infractions too numerous to mention. Even though there is CLEAR SIGNAGE above each bin to indicate what is, and what isn't, recyclable.
I work at a small-ish high-tech company that employs a lot of young people with young families. Depressing that they don't seem to know better, or care.
