What does it mean to reuse? It is purchasing items that can be used over and over again, like cloth napkins instead of paper ones.
Many of the things we normally think of as recyclable or as garbage can be used again or made into a new, useful product. Sometimes it really isn't garbage, just resources waiting to be reused.
We all have items we no longer want. Before you throw the item out, ask yourself these questions: Is the item reusable for its original purpose? Could it be used for something else? Could someone else use it?
