And this is the survey of the different types of paper:
HOW IS PAPER PRODUCED?
In this

WHERE DOES
PAPER COME FROM?
We can classify paper into three different columns:
- - Information- media (newspapers, magazines,
books, office, photocopying, advertising
sheets, etc.).
- -
Domestic (tissue paper rolls for kitchen, coffee filters, tissues, etc.).
- -
Packing (bags, Paper packing, etc.).

So we have to use recycled paper because:
·
It doesn't need any tree.
·
It uses less water in its production.
·
It needs less energy to be produced.
