Antioxidants, a future business for the paper industry

When pulp is removed from cellulose, paper mills produce a substance known as black liquor. Up until now there has been little use for it, and it is often burned to produce electricity. In CENER laboratories, however, it is being recovered in order to extract and processkraftlignin, a polymer that researchers have used to develop an antioxidantfrom a renewable source. The initiative, coordinated by ADItech, acting in turn as the coordinating agent for SINAI, and funded by Navarra’s Regional Government, not only aims to offer a new product to agri-food, industrial, and cosmetic companies, but also represents a potential new line of business for the paper sector.
