It is important to note that not all paper can be recycled. For example, paper that is coated with plastic or foil cannot be recycled. However, most types of paper, including paper that has been written on, can be recycled.
When you recycle paper, you are helping to reduce the amount of waste that goes to landfills. You are also helping to save trees, as recycled paper can be used to make new paper instead of using new trees.
