As the grand marshal of Sunday’s Strawberry Festival parade, Rita Materni may be waving, but she won’t be chucking candy at crowds. But if she did, she’d probably shout out, “Recycle that wrapper!” She’s joined two “brigades” through www.terracycle.net, collecting used cookie wrappers and juice pouches and getting paid 2 cents for each. These items are turned into unique accessories and other products, according to TerraCycle, which says that over 10 million people worldwide have collected 1.8 trillion units and earned over $1 million for charity.
