Paper recycling

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 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 corrugated containers  old magazines, and newspapers.Paper suitable for recycling is called "scrap paper", often used to produce molded pulp package

paper recycling process:

The process of waste 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 recycled paper.
