Recycling information billboards

I recently submitted this nomination. It is on city property close to the local park for easy access, its permanent all year round. Im just confused on the reasoning for rejection and if this is in fact eligible or not. Thank you

This does not appear to meet any eligibility criteria. If it were a sign about how recycling facilities work, recycling's environmental effects, or whatever, you could probably say it's an educational sign, but this is just a sign saying "here is a list of what you can recycle."
Its a trash POI, pun intended.
