Trees paper how many

While the majority of paper is made from pine trees, often other trees are used to create the pulp that will then become a sheet of paper. As well as the different types of trees used, another consideration is the fact that trees will always vary in the size and shape. Some trees will be tall with thin trunks while others may be shorter and wider.

Of course, trees will always vary depending on their age, environment and type of tree. It is estimated that a standard pine tree, with 45ft of the usable trunk and a diameter of eight inches, will produce around 10, sheets of paper. In fact, on average, an office will use the equivalent of one tree every year, even in offices that limit their paper usage and strive for a paperless office.

Another consideration is that coated paper that is used for high-quality printing and magazines will require more pulp. In fact, one tone of coated magazine paper uses over 15 trees. For paper used for newspapers, it takes around 12 trees to create one tonne of newspaper. When you consider how many magazines and newspapers are printed and distributed across the world, it is difficult to visualise the number of trees being used.

Paper is an important part of modern life. People use it in school, at work, to make artwork and books, to wrap presents and much more. Trees are the most common ingredient for paper these days, but people have been taking notes and creating artworks for a very long time using lots of other kinds of surfaces and materials. Humans painted pictures on cave walls during the Ice Age. The oldest known drawing, found on a small rock in South Africa, was made 73, years ago.

Written language came a long time later. The Sumerians , in what is now Iraq, and the Egyptians used pictures in the first written languages more than 5, years ago. These people etched cuneiform and hieroglyph pictures that formed their languages into rock.

They also wrote on slabs of wet clay, using a pen or brush made from a reed. Sometimes they baked these slabs hard in ovens to preserve them. The Egyptians pioneered the first paper. Papyrus came from a foot-tall 4. They cut the stalk into thin strips, pressed them together and dried them into the long rolls you can now see preserved in museums.

Papyrus made it easy to carry their writing with them in rolled up scrolls — much easier than carting around heavy clay tablets and rocks. Wood tablets covered in beeswax became a popular writing material in Greece, Rome and Egypt.

Children used them in school as you might use notebooks today. Heating the wax made it easy to erase the writing and reuse the tablets. The Romans took the next step, making books with papyrus pages. Special manuscripts used pages made of treated calf skin. In China, ancient writing materials included bone, bronze and wood.

So that means a pine tree yields about pounds of paper. I have a ream of paper for a photocopier here and it weighs about 5 pounds and contains sheets you often see paper described as "pound stock" or "pound stock" -- that is the weight of sheets of 17" x 22" paper.

These are all fairly rough estimations, and I weighed things on a bathroom scale , but you get the general idea. See the next page for learn more. Sign up for our Newsletter! Mobile Newsletter banner close. Mobile Newsletter chat close. Mobile Newsletter chat dots. Mobile Newsletter chat avatar.
