"Broke" refers to partly or fully manufactured paper or board that is discarded from paper or board making, converting, and finishing processes. It also refers to the stock made by repulping these materials. Broke is continuously being produced, and it is the job of the "broke system" to collect this valuable resource, process it, and make it available for reuse. Because broke can amount to well over 5% of a machine's total production, broke is an important fiber source and the broke system is an essential part of the papermaking process, from both financial and operational perspectives.
