Paper from any point in the paper making process which is suitable only for repulping, e.g. Wet paper removed from the paper machine or dry paper arising as trimmings, faulty paper etc. Not strictly speaking recycled, as mills have always put broke back into the process, but certainly better than sending it to landfill. In some recycled definitions, broke that goes back into the same grade is not categorised as recycled, where broke that is used in a different grade is.
Paper or board that is discarded at any stage during its manufacture and is usually repulped. There are 2 kinds - wet broke, which is accumulated at the wet end of the papermaking machine; dry broke which is accumulated at any stage on the dry end of the machine, trimmings from the reeling, slitting and cutting operations, as well as paper or board rejected during sorting.
