hey!i've got a question: does anyone know how many paper leaves are made from an average tree?(:?

Answer 1

There are several variables to any quote included here that are not stated. Different trees yield different volumes of wood. Also paper is made at different paper densities in grams/m2. Typical office paper has 80 g/m2 or 5 g/81⁄2 x 11” sheet.

International ream 500 sheets - for 2500g/ream of office paper

1 US ton = 907,185g or 363 reams of office paper

" US conservation pressure group Conservatree, has calculated that one ton of uncoated virgin, or non-recycled printing and office paper uses 24 trees."
Hurley added that "in newspaper production, a ton of 100 per cent virgin newsprint uses 12 trees."

I calculate that out:
1 ton/24 trees -> 37,799g/tree or 15reams/tree (if using office paper weight 5g/sheet) 15x 500 = 7500 sheets/tree

"12,500 sheets of paper can be made from 1 tree" from an online fax service provider.

I calculate that out:
12,500 sheets/tree x 5g/sheet = 62,500g/tree
62,500g/tree / 2500g/ream = 25 reams/tree (if using office paper weight 5g/sheet)
25 x 500 = 12,500 sheets/tree

Greenprint company states
1 ton of paper = 400 reams = 200,000 sheets
1 tree makes 16.67 reams of copy paper or 8,333 sheets
1 ream (500 sheets) uses 6% of a tree (and those add up quickly)

"Only about 17% of the 3.3 billion cubic meters of wood consumed worldwide each year is for papermaking, and much of this wood is in the form of wood chips and other residue left behind from sawmill operations." "Lumber and building products can be made from the trunk, primarily from large trees whose diameters are greater than 8. The remaining wood is recovered in the form of trimmings and wood chips, and is used to make paper."
