Why paper? Who cares!? People need to say stuff! And they have a lot of stuff to say! The United States Library of Congress in Washington D.C. ranks as the largest library in the world. It holds over 118 million items which require more than 500 miles of shelving.
Where paper came from… It all started with painting pictures on caves, thousands of years ago
Where paper came from… • One of the first written languages was Cuneiform, written on clay tablets (3000 BC)
Where paper came from… • People later began to write on anything: Fabric, Bamboo, Bone, Turtle Shell & Bark
Where paper came from… Around the same time as cuneiform, the Ancient Egyptians were writing hieroglyphics on sheets of papyrus This is actually where the word “paper” comes from (even though it’s not paper as we know it)
Where paper came from… Paper made from pulp was invented in China (105 AD) Paper was one of the 4 great inventions of Ancient China (along with gunpowder, the compass and printing)
Where paper came from… Meanwhile, in Europe, writing was still being carved in stone, such as Ogham writing in Ireland and runes in Northern Europe (400 AD)
Where paper came from… For a while, vellum (animal skins) became popular, in parts of Asia, Egypt, and Europe Recognize this?
The spread of paper making… 900 AD 750 AD 100 AD
How did we get… to this! From this
mass production Of books c. 1440 http://atlas.lib.uiowa.edu/press-animation.html
mass production Of paper c. 1798 This type of machine is still the one used today!
So…where does most paper come from? spruce pine birch Larch poplar hemlock

Do you think there are any problems for the environment with making and using paper?
A question for you… • How much wood does it take to make one ream of paper (500 sheets)? a) a few sticks b) a small fireplace log c) a bundle of logs d) half a tree e) a whole tree
+ + + Source: http://www.paperonweb.com/chemical.htm Energy equal to 10 L of petrol 1 bundle of logs 800 L of water A load of chemicals!
What is the future of paper?
Replacing Paper • With devices like the Kindle and iPad, you can read books without using paper
Replacing Paper • With devices like the Kindle and iPad, you can read books without using paper • There’s even electronic paper (e-paper) made from plastic.
Digital stuff can also be projected… Even projectors are getting smaller!
But… paper demand is rising
But… • total value about $400 billion • one third of wood harvest used for paper making (most of the rest is for fuel) • about one third of the fibre used to make paper comes from waste paper; most of the rest is made from wood pulp from fresh trees paper demand is rising
So why do people STILL use so much paper? Easy to get Convenient to use Well developed industry cheap
Paper can come from other plant fibres (and not from cutting down trees) Waste paper (recycling) Fibre crops: plants grown specifically for their fibres, like kenaf (hemp) and flax Agri-residue (farm crop waste)
They are all made the same way… are flattened Fibres
Use less paper! Always use both sides! Buy used books! Sell your own books! Newspaper is the new giftwrap! Turn your trash into treasures! Recycle what you do use! Think carefully about what you do buy! (non-bleached, paper from sustainable forests, recycled paper or even better…bamboo, kenaf, or flax) What can you do?
