I signed up Dominic's school with a program called www.terracycle.com. You can even print a mailing label, so there are minimal shipping costs (just the cost of a padded envelope or box). Right now, I send them used Capri Sun pouches. The next time you think about throwing something out because you think it's "junk" take a few extra minutes to determine if it really can't be recycled or reused. You just might be doing something good for the environment!!
