One tissue cut how many tree?

Assume one tissue is tree-source (ie not tree-free type).



How much paper in one tree? It really all depends on the size and type of the tree.. as

different trees yield varying quantities of pulp and different paper grades. Because of these variables, it is not possible to determine how much paper is made from a single tree. Cord is the unit measurement of how much wood fiber can be used to produce paper products. All measurements of how much wood fiber in pulpwood is used to produce paper products are in cords or tons. A pulpwood cord is a stack of logs four feet tall, four feet deep and eight feet long (4 x 4 x 8). An acre of forested land may yield an average of 10-15 cords of wood.



According to http://www.toiletpaperworld.com/tpw/encyclopedia/navigation/funfacts.htm :

1,000 pounds of toilet paper can be yielded from one cord of wood

The average roll weighs 227 grams, including the cardboard core tube. This is just over half of a pound. Hence, 1000/0.5=2000 rolls

Average 500 sheets per roll (4.5x4.5 inch per sheet, 2 ply)..

Hence, 2000x500 sheets = 1,000,000 sheets of toilet paper per cord of wood



Assume size of one tissue is about 4 sheets of toilet paper:

250,000 sheets in one cord of wood.

1 sheet of tissue = approx 1/250,000 cord of wood



Since 1 cord of wood = 128 cubic feet = 221,184 cubic inch

=> 1 sheet of tissue = approx 1/250,000 x 221,184 = 0.88 cubic inch of pulpwood fibre

cut many tree!!!
