When in Doubt, Throw it Out!
Even though you may have the best intentions in mind when recycling, if it isn't done right, just one non-recyclable item can spoil an entire batch of otherwise good materials.
The 4 Rs
RECYCLE what you can’t refuse, reduce or reuse. Recycling should be the last resort in the waste hierarchy. Pay attention to the entire life cycle of items you bring into your life - from source, to manufacturing, to distribution, and to disposal. All recycled items must be EMPTY, CLEAN, and DRY.
