Did you know About Paper Industry…?

  • The pulp and paper industry represents around 10% of all global emissions of carbon dioxide.

  • Energy consumption by pulp and paper industry this year (2010) is projected at 25.8 billion kWh of electricity and 54.3 billion BTU's of fossil fuels.

  • Pulp and paper industry uses 75-225 m³ water per ton of paper, more than any other industry to produce a ton of product.

April is the paper-less month in the Library. Let's meet our goal to reduce our printing library-wide by at least 10%! Join in the action, and try the following quiz:
Options: (a) 637; (b) 17980; (c)189; (d)23374; (e)416556.

  • During last year, Library purchased 3596 reams of paper for staff and patrons;

  • The amount of paper would make a stack of about _____ feet tall and weight _____ pounds;

  • The paper consumption roughly equaled ____ trees used for paper consumption;

  • These were the equal about ____ pounds of carbon dioxide not removed from the atmosphere, and ____ pounds of carbon dioxide emitted during the manufacturing process.

Tips : Print less – save more -

  • Print responsibly: Use "Print Preview" and print only what you need.

  • "Print" (or save) to PDF using CutePDF or Adobe Acrobat Writer.

  • Save to a flash drive or email documents.

  • Print on both sides of the paper and use narrower margins.


Fact about 1 ream of paper:

  • It's about 2-2.25 inches thick and 5 pounds.

  • It takes away about 5% of a tree, and each tree used in making paper removes about one metric ton of carbon dioxide from the atmosphere every year.

  • U.S. paper industry emitted around 17.2 million metric tons of carbon dioxide to produce 83 million tons. This is the equivalent of about 6.5 pounds of carbon dioxide per ream during the industrial process.

  • There are 12 major steps in the paper making process.
    Step 1- Take trees from forest and transport them to the paper mill.
    Step 2- Cut logs into desired length.
    Step 3- Strip bark from logs.
    Step 4- Grind wood into large chucks.
    Step 5- Chip wood into smaller sizes, about one inch cubed.
    Step 6- Inspect the chips to ensure they are correct size, also known as chip screening.
    Step 7- In chemical pulping, wood is cooked in a “digester” at elevated pressure with a solution of the appropriate chemicals which dissolve the lignin and leave behind the cellulose. The cooking process results in emissions of a variety of hazardous air pollutants including formaldehyde, methanol, acetaldehyde, and methyl ethyl ketone.
    Step 8- Wash the cooked wood chips, which are now in pulp form.
    Step 9- Screen the pulp to ensure uniformity.
    Step 10- Bleach the pulp, which usually includes using chlorine and various other hazardous chemicals.
    Step 11- Beat the pulp until desired consistency is reached. Heavy use of water
    Step 12- Drying the paper and then rolling it into easily moveable rolls. This is the most energy intensive process.
