Reviews of some different incoming recovered paper quality control methods, procedures and tests are provided based on visits to mills in the USA and Europe. Visual inspection, bale audits, laboratory tests, and source monitoring are discussed. Contaminant levels in recovered paper from multiple stream versus single stream collection are compared. Recovered paper inspection procedures can help reduce downtime for stickies; help identify sources with too many contaminants; and can help calculate yield and improve final quality. The value of these benefits should be tracked to justify the expense of more incoming recovered paper quality control.
