Guest guest Posted May 23, 2008 Report Share Posted May 23, 2008 Paper Recycling Paper is one of the most versatile and important materials used in homes, schools, offices, and businesses throughout the world. Each day we enjoy the benefits of paper products ¨C from the newspaper we read in the morning; to the box that holds our cereal; to the paper we use for homework and business purposes; and the documents that mark the significant achievements of our lives. Paper dates back over 2,000 years and hand-made production methods were used until the 19th century. The industrialization of the paper making process helped to bring education and books to a broad spectrum of people, and continued advances have resulted in better and more efficient products that meet our daily needs, while leaving a smaller footprint on our environment. The Facts About Paper and Paper Recycling In 2006, the amount of paper recovered for recycling averaged 357 pounds for each man, woman, and child in the United States Every ton of paper recycled saves more than 3.3 cubic yards of landfill space By 2012, the paper industry¡¯s goal is to recover 55 percent of all the paper Americans consume for recycling, which is approximately 55 million tons of paper More than 37 percent of the fiber used to make new paper products in the United States comes from recycled sources 86 percent (approximately 254 million) of Americans have access to curbside or drop-off paper recycling programs Buying recycled paper is an equally important step in the recycling process ¨C it closes the recycling loop. Even though trees are a renewable resource, much energy and landfilll space can be conserved when we buy recycled content paper. When buying recycled content paper, remember to look for the highest percentage of post-consumer waste content (the largest percentage of waste paper used to make the new, recycled-content paper). Recycled Also, make sure to look for the Recycled symbol which means that product is made out materials used before. There may be a statement next to this symbol that mentioning the percentage of recycled-content in the product. Recyclable Confused by this symbol? Don¡¯t be. This one means a product can be recycled ¨C Can Paper Continue To Be Recycled? Each time paper is recycled, the fiber length decreases, which impacts its strength. It is estimated that paper has approximately seven generations, meaning it can be recycled up to seven times. Because paper is made from a renewable resource, introducing new, or ¡°virgin¡± fiber into the process is a logical answer. Today approximately 80 percent of the nation¡¯s paper mills use some recovered fiber in the production of new paper and paperboard products. Further, the U.S. forest products industry plants an average of 1.7 million trees every day - five new trees for every tree harvested. Thanks to the responsible forestry practices of U.S. companies, the amount of standing timber in U.S. forests has increased by nearly 40 percent over the past half-century, and by 10 million acres since 1990. How to Make Recycled Paper Trees are made up of cellulose fibers that are held together with a glue-like substance called lignin. This makes trees strong enough to use for building houses and furniture. When wood is cooked, the cellulose is separated from the lignin to make wood pulp. This pulp is made into paper. In ancient times, people wrote on animal skins, bones and clay tablets. Around 3500 BC, the Egyptians wrote on a woven mat of reeds called papyrus, which is where the word paper comes from. Around 2,000 years ago, the Chinese discovered that they could make a thin paste of mulberry bark, hemp and rags and let it dry into a sheet in the sun. Many types of paper are now made from wood. The modern day method of making paper is as follows: Logs are chipped into small pieces of wood. These chips are cooked with chemicals that dissolve the glue-like lignin holding the wood fibers together. This process leaves a pulp made of cellulose fibers and lots of water. Then, the pulp is put on a screen to let the water drain away. The fibers remain to form a sheet of paper that is dried and put on a roll. When we recycle paper we use the wood pulp/cellulose over and over again. NOTE: Making recycled paper can be a bit messy, but fun. Have appropriate supervision because the process involves using an electric blender and a utility blade and/or scissors. Materials Needed To Make Recycled Paper A newspaper A blender Water A kitchen sink with a good drain plug or a large plastic tub/container Four clothes pins Two 9¡å aluminum pie pans (square or round) One square foot of fiberglass screen A marking pen Scissors or a utility knife Optional A sponge and blotting paper Rolling pin Colored construction paper Colored threads Glitter Small leaves Step 1¡ªMaking Your Deckle A deckle is the frame and screen that the paper pulp will be made on. It allows the fibers that make the paper to collect on the surface of the screen and the water to drain through. To make your deckle you will need to get an adult to help you. First, take the aluminum pie pans and draw a circle or square, depending on what shaped pans you have (circle in circle, square in square), 1 1/2¡å to 2¡å from the edge in the bottom of each pan. Then using the utility blade or scissors, cut out the circle or square. Place your pie pan on top of the square-foot of fiberglass screen and trace the shape of the outside of the pan in the middle of the screen with a dark coloured pen (lay newspaper on your working surface so that you do not get ink on the counter!). Draw four tabs on the square or circle that extend to the edge of the screen. Cut out the tabbed circle or square. Layer the screen between the two pie pans and use the clothespins to hold everything together at the site of the tabs. Step 2¡ªMaking The Slurry Slurry is the paper pulp and water mixture. It might remind you of dirty old oatmeal. To make the slurry you will need to get an adult to help you. First, tear a section of newspaper into roughly one inch pieces. Place one cup of the torn newspaper into the blender with two cups of water. Put the lid on the blender and turn it on high. Let the blender run until all of the paper disappears and it appears as if you have a purple-grey, pulpy mixture (again, it may remind you of dirty old oatmeal). Place about four inches of water into the kitchen sink (with the drain plugged) or large plastic tub/container. Add the slurry mixture to the water in the sink or container. You may notice that the suspended paper fibers in the water that make up the slurry feel soft. If you look really closely at other paper fibers in paper products such as tissue or toilet paper (pull the paper apart a little), you may notice that the fibers look similar! Step 3¡ªMaking The Paper Mix up the slurry and water mixture in the sink or container really well. You can use your hands! NOTE: You will need to mix the slurry each time you make a new piece of paper. Hold your deckle with both hands on the pie pan edges and scoop it down towards the bottom of the sink or container at a slight angle. Slowly lift the deckle out of the water allowing the water to drain out (back into the sink or container) for about a minute. You should have a thin layer of paper fibers settling on the surface of the fiberglass screen framed by the edges you cut out of the pans. NOTE: You do not want to have it too thick (more than 1/4 inch) or too thin (you can see the screen in patches) on the screen of your deckle or the paper will be difficult to work with. You can run your finger along the bottom of the screen to help get the water off. Set your deckle down on a piece of newspaper and open your deckle by removing the clothes pins and top pan from the stack. Carefully lift the fiberglass screen with the paper on it by the tabs and move it to a flat piece of newspaper. You can press a piece of newspaper over the paper (you can use a rolling pin to press if you desire), or press a piece of blotting paper over the paper and use a sponge to eliminate some of the extra water. NOTE: You do not want to dry the paper too much while it is still on the fiberglass screen or between newspaper or blotting paper as it will stick. Gently peel the paper off the deckle screen and place it on a piece of newspaper to dry. Once your paper is dry, you can use it! You can write on it, draw on it, fold it, etc. In the picture above, you can see the paper on the screen of the deckle. You can experiment further by adding a cupful of colored construction paper blended in the same manner of the newspaper to your slurry to make colored paper. You can also add colored threads, glitter, small leaves, etc. to the slurry to make the paper more interesting. From Willowlady Quote Link to comment Share on other sites More sharing options...
