Everything You Need to Know About Paper Recycling
The recycling of paper is the process by which waste paper is turned into new paper products. It has a number of important benefits: It saves waste paper from occupying homes of people and producing methane as it breaks down. Because paper fiber contains carbon (originally absorbed by the tree from which it was produced), recycling keeps the carbon locked up for longer and out of the atmosphere. Around two thirds of all paper products in the US are now recovered and recycled, although it does not all become new paper. After repeated processing the fibers become too short for the production of new paper – this is why virgin fiber (from sustainably farmed trees) will be added to the pulp recipe.
There are three categories of paper that can be used as feed stocks for 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 in a paper mill.
Pre-consumer waste is a material which left the paper mill but was discarded before it was ready for consumer use.
Paper suitable for recycling is called “scrap paper”, often used to produce molded pulp packaging. The industrial process of removing printing ink from paper fibers of recycled paper to make deinked pulp is called deinking, an invention of the German jurist Justus Clap Roth.
Process
The process of waste paper recycling most often involves mixing used/old 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 (especially from plastic-coated paper) that may still be in the mixture then cleaned, de-inked (ink is removed), bleached, and mixed with water. Then it can be made into new recycled paper.
