The first R means choosing products very carefully to reduce waste as much as possible. Reusing involves the repeated use of items. The third R is about separating materials that can be recycled and later used for a new purpose. There are also economic benefits to living green. Reducing the use of energy and water can help save money on household bills. Furthermore, reusing products and materials is another way to make saving. It helps save on production costs since creating new products wastes materials and is expensive.
