Students diverted more than 3,000 drink pouches from landfill and donated them to TerraCycle, which "upcycles" non-recyclable materials into 200 new products.    Staff Photo/TAMARA SHEPHARD Most kids toss their non-recyclable drink pouches in the trash. Dixon Grove Junior Middle School students donate their drink pouches by the thousands to TerraCycle, a North York-based company that repurposes them into fashion bags, tote bags, lunch bags and pencil cases. TerraCycle gives the Etobicoke elementary school $0.02 per pouch, proceeds of which will send students to the Humber Arboretum and the Don Valley Brickworks before the end of the school year.
