Keep Those Recycling Bins Closed! Email Keep your recycling bin lids closed! Not only does it prevent loose items from blowing away in the wind, it also keeps your recyclables dry. This is especially important during a stormy season. Wet paper and cardboard cannot be recycled, and what’s worse, their wet, damaged fibers can contaminate other paper materials once they are combined. So remember: Keep your recyclables safe and dry by keeping your bin lids closed!
