Paper comes from trees. It takes about three tons of wood to get one ton of paper pulp.

On the other hand, the paper bags have a number of drawbacks. The main disadvantage of the paper due to the fact that it is afraid of water. Using lamination helps a little.
Another and very significant drawback - the high cost of raw materials and ways to improve it. If you take it to a recycling center it means more energy and chemicals are used.
