It may seem like a silly question, but it's more complicated than you think.
Because Envirobank's orange collection bags are reusable, we kindly ask that you don't tie the drawstring to keep the bag closed. This means our processing teams often have to cut the drawstrings, which means the bags cannot be reused until the drawstring is replaced.
Instead, we suggest taking the ring-pull off an aluminium can (there's a good change you have one inside your orange bag). Thread the drawstring through the hole on the ring-pull and slide it down towards the bag. The ring-pull works like a toggle, and keeps the bag securely closed, but is easy enough to remove when we need to get to the containers inside!
