Paper: Recycle vs. Trash

 

As it was written in the Wikipedia, Paper is a material that is made from either Trees, Rags or Grasses, when they are moist, press together and dry, they become clean paper. Paper can be used to write, print copies, draw or fold and cut on them. The first paper that have been made was date back in the 2nd –Century B.C. in China, When Cai-Lun, a  2nd –Century A.D. Han Court eunuch, had made the first papermaking process. Because of his process of making paper, it has spread from China through the Middle East to Europe in the 13th- Century, where the first water-powered paper mills were built. In 1844, Canadian inventor Charles Fenerty and German F.G. Keller independently developed processes for pulping wood fibers.[4]

 

Paper can be made in three different ways:

 

1. Chemical Pulping: A process on separating the lignin from cellulose fibers on a tree. The lignin is dissolved in cooking liquor so it can be washed from the cellulose fiber. Paper that is made from chemical are also known as wood-free papers, papers that don’t have lignin (which by the way is wood chemical), they can also be bleached to become white paper, but it will contain 5% of the fibers.

 

2.  Mechanical Pulping: There are two kinds of Mechanical pulping: Thermo Mechanical and Ground wood. In Thermo Mechanical process, wood is chipped and then fed into large steam-heated refiners where the chips are squeezed by two steel discs and made into fibers to become paper. In Ground wood process, debarked logs are fed into grinders where they are pressed against rotating stones and made into fibers. Unlike the chemical pulping, The mechanical pulping does not remove the lignin, so the paper becomes yellow and brittle over time, but somehow the mechanical process costs less than the chemical.

 

3. Deinked pulp: This process can be either use chemical or mechanical pulp, by mixing with water and applying mechanical action to the hydrogen bonds, so the paper can be broken and the fibers are separated.

 

There are three main classifications of Recycled paper:

·        Mill broke or internal mill waste

·        Preconsumer waste

·        Postconsumer waste

With the finishing touches the paper is taken to a machine where it will press to remove water and to another machine to dry and it will undergo sizing to alter its physical properties and to what the consumer may use.

            The only problem of Paper is the impact of the Environment and the cost between regular and recycle paper. The impact on the Environment is Deforestation, with 35% of harvest trees are being cut down and used to make new paper, but with new paper, can also cause paper waste which can add up to 71.6 million per year in the United States alone. The cost of Regular paper can be less than recycle, but will have the effect on the environment. But with Recycle paper, they can deinked the paper and used it over and over again. So the Difference between Regular and Recycle paper is that with Regular paper, thus can damage the forest habitation and the climate from the process of making paper. With Recycle, it can save the forest and can be used over and over again but cost more than Regular, so think wisely of what paper you used and know the effects on the Environment and Climate and perhaps someday we can come up with a better way to save the Environment and Climate and still get new paper.
