Recycled paper is easily accessible, usable, and affordable, and there are two kinds of recycled paper available. Pre-consumer waste is scraps from the paper mill used to make recycled paper, and post-consumer content recycled paper is made from paper that has already been used and recycled by the consumer. Using recycled paper instead of virgin forest fiber paper reduces energy consumption by 44%, net greenhouse emissions by 38%, particulate emissions by 41%, wastewater by 50%, solid waste by 49%, and wood use by 100%. Knowing the difference between post-consumer and pre-consumer recycled fibers will help purchasers make educated choices on paper products.
Paper scraps and trimmings from a paper mill are called “mill broke” and these are also known as pre-consumer content or waste. These paper scraps, which have never reached there end use, can be recycled back into paper at the mill. It is typically from printers’ trimmings or damaged paper rolls, and when mixed with water, it can be turned back into paper pulp. The paper mill can manufacture the paper pulp internally to make recycled paper.
Post-consumer waste (PCW) recycled paper is paper that has been printed on and used by consumers or commercial entities. There are different amounts of PCW used in recycled paper, and these are noted on the packaging of paper products including copy paper, letterhead, and envelopes. The Environmental Protection Agency requires a minimum of 30% PCW to allow paper to be called “recycled.” 100% post consumer waste recycled paper is readily available, and significantly more environmentally friendly.
When purchasing paper products, look for 100% PCW, as well as 100% processed chlorine free (PCF) products, both of which are clearly marked on package labeling. These standards exceed the EPA requirements, and are the best environmental choice. Chlorine-free bleaching methods avoid the production of dangerous toxic residues during the bleaching process, which pollutes rivers and streams and can be harmful to the health of wildlife and humans.
