The How to Recycle anything guide is impressive and just because we're done with something doesn't mean that item has been completely used up yet.
This also gives you some ideas on what to buy next time around. For example, Mac's recycling program for makeup makes me want to start using them over other companies who don't recycle or bother to encourage people to do so. You can also send your old Christmas lights for recycling and get a discount for new ones.
Who knew when you did something to save the planet, you might also save a little dough in return?
