Reading about differences in recycled paper content, I have come across the term "mill broke." What exactly is mill broke?
Mar 28, 2018

Mill broke is paper that is discarded at any point during its manufacture and repulped. Mill broke has never been in the consumer stream. Mill broke has always been recycled to reclaim the cellulous fibers, and until recycling became an environmental concern with consumers, mill broke was not included in the description of the paper. Post-consumer waste consists of paper fibers that have been recovered from the consumer waste stream through a de-inking process. The de-inking process damages the paper fibers, and the de-inked fibers are not considered to be of the same quality as virgin fibers. Paper containing recycled fiber will often state the total recycled fiber content along with the amount of post-consumer waste. A paper may claim 40% recycled content and 20% post-consumer waste. This means 20% of the paper fibers are from post-consumer waste (de-inked, used by the public) and 20% would be from other sources, including mill broke.
