Surfactants on cleanup detail in paper mills
- PPG Industries, Inc., Pittsburgh, PA (United States)
From pulp production to paper coating, surfactants are involved in almost every facet of pulp and paper manufacturing. Within the industry, the role of surface-active agents is growing every larger with the demand for recycled paper. In the US, for example, The American Forest and Paper Assn. has established an ambitious goal of recovering 50% of the paper used in the US by 2000. By then, paper producers in North America are expected to have invested more than $10 billion in recycling equipment, and be spending more than $300 million/yr on drinking chemicals, including surfactants. Surfactants will also serve the industry indirectly, as additives in the production and formulation of products sold to the paper industry, including biocides, retention aids and water-treatment polymers. Providing higher-quality paper while reducing dependence on virgin pulp, requires manufacturing technologies and process chemicals that can restore wastepaper to its original state. Achieving those goals will depend on the development of novel surfactants through close collaboration with mill customers, and pioneering research in surface science, polymer engineering and organic chemistry.
