California printers and publishers (consumers) annually certify to the California Integrated Waste Management Board (CIWMB) the total amount of recycled-content newsprint (RCN) and non-RCN that their businesses use. Newsprint manufacturers that produce RCN used by California printers and publishers must also annually certify how much de-inked pulp they received or produced and how much RCN they distributed to California’s newsprint printers and publishers.
