Many of us return our plastic bottles and cans. Noticeably fewer recycle their glass. Maybe that’s because we don’t get any money in return, as we do for cans and plastic. Can we change this attitude by making recycling glass fun to do? So you are not just rewarded with a good conscience, you also get a smile.
