For example, a national crayon recycling program will recycle your kids old crayons into new ones. Crocs will recycle your old Crocs into new ones and donate them to underprivileged families. If you're taking all of your CD's out of the jewel cases for smaller storage, you can send those cases away to be recycled too. St. Judes will take your old Christmas cards and kids will use them to make new ones.
It's a little more work on your part to give your stuff a second life, but so much better than filling up the landfills.
