Paper recycling Due to the increasing of population, more and more resources were consumed, the resources need long time to resume if they were done. And population in the world is increasing every year. So, we must protect our resource in order to that we live better. But how to protect the resource, in my opinion, except save resource, anything recycling is very important. Recycling is the process of making or manufacturing new products from a product that has originally served its purpose. For example, the scrap paper can second use through recycling Why is paper recycling important? First, paper recycling can protect the resource of tree. Second, it has the economic benefits. Recycling can create employment opportunities for a lot of people. Third, it can save environmental conditions and reduce pollution. Paper recycling is the process of turning waste paper into new paper products. There are three categories of paper that can be used as feedstock making recycled paper: mill broke, pre-consumer waste, and post-consumer waste. Mill broke is paper trimmings and other paper scrap from the manufacture of paper, and is recycled internally in a paper mill. Pre-consumer waste is material which left the paper mill but was discarded before it was ready for consumer use. Post-consumer waste is material discarded after consumer use, such as old magazines, old newspapers, office paper, old telephone directories, and residential mixed paper. How to paper recycling? The process of paper recycling involves mixing used paper with water and chemicals to break it down. It is then chopped up and heated, which breaks it down further into strands of cellulose, a type of organic plant material; this resulting mixture is called pulp, or slurry. It is strained through screens, which remove any glue or plastic that may still be in the mixture then cleaned, de-inked, bleached, and mixed with water. Then it can be made into new paper. The same fibers can be recycled about seven times, but they get shorter every time and eventually are strained out. Paper recycling is so important, we should insist to do it. I hope a green earth forever.
