They use it to heat their shops or they can recycle it.

If he walks the streets collecting recycleables, he needs to do that.

Then you meet them at the property, hand them the key and give expectations such as when and how to replace air filters, properly use the thermostat including making sure the fan is on 'auto' and never 'on', where the trash/recycling cans are kept and when to put them at the curb, etc. 

Is there a way to recycle your quarters back to your tenants using a bill changing machine?

Two carts for regular trash, two for recycled, two for yard waste.  

I would also include something about the exterior- we have local ordinances about porch/yard furniture having to be outdoor furniture (to keep people from the classic couch on the porch), when and where to place garbage bins and recycling, and keeping the yard cleaned up (no garden or solo cups and beer bottles etc).  

Be sure to give them a deadline to fill it out as well.Let them know when trash and recycling is picked up and where to place it.

I agree with most of the comments above, the eagle does not play an important role in fact you could probably just use some variation of "green" "recycle" type icons and a home.

Next time you are at a metal recycler, grab some!  

I have to pay for each use of the HELOC, but I can recycle the REFI money over and over...but only pay for it once.
