When a roll of toilet paper is made, 220g of paper pulp is used as material. If we don't waste 30m of it which is over all 70m, we can save about 8 trees(When making a ton of pulp in 20 trees around 30 years old).
But we often pull some piece of toilet paper out of it heavily, thereby wasting it and removing trees. If you use it after inserting "Tri steper" into the loo roll tube, you will save amount of trees.
