Mystery Notice

Earlier today someone rang our buzzer and when I went outside he started rambling on in Polish. When I told him I didn't understand he seemed to walk away. Later when I went outside I found this notice along with a clear blue plastic garbage bag. I have zero interest in spending the time to translate this - anyone care to take a Google translate stab at it? The last time this happened it was the plastic bags we needed for recycling, luckily there were pictures on the bags so I figured out what they were for, and the Polish neighbor/landlord happened to be over that day and used hand gestures to show me where the hidden clear string was to tie them closed. I really do just need a personal translator at my side at all times.
