Some of us are feeling a tad guilty about eating the kids' Halloween treats. Well, here's a way to atone -- we can recycle all those candy wrappers through an ongoing partnership between Mars candy and the eco-friendly company TerraCycle. "It's a free collection program for all kinds of candy wrappers, regardless of brands, regardless of type," said TerraCycle public relations manager Stacey Krauss. In a phone interview, Krauss told us how easy it is to help both the planet and the charity of your choice by joining the "candy wrapper brigade." Simply sign up on the TerraCycle website and designate which nonprofit you would like to receive the funds or points earned.
