Marathon Strides. Highly enterprising is Marathon Paper Mills of Rothschild, Wis., makers of food containers and chemicals. In 1927 Marathon summoned Chemical Engineer Guy C. Howard, gave him a platoon of Ph.D.s and the job of finding more profitable channels for waste lignin than the Wisconsin River. Today, after 15 years of research costing some $2,000,000, Marathon adds lime to its waste liquors, precipitates out calcium lignin sulfonate, turns it into...
...Vanillin, the flavor constituent of vanilla. Last year one-half of U.S. vanillin was synthesized from U.S. lignin, consumed by General Foods, Hershey, National Biscuit, countless numbers of ice-cream makers, the Army & Navy...
...Plastics in both common forms: 1) molding powders from which odd-shaped objects are pressed; 2) laminated sheets-i.e., layers of paper or cloth bound together and coated with lignin derivatives-which are used in such simple large-surface products as tabletops, refrigerator and airplane doors. Laminated lignin plastics are one-half the weight of aluminum, one-fifth the weight of steel. Pound for pound they are as strong as steel. The expanding U.S. output of lignin plastics can be used almost entirely for military purposes, e.g., parts for ships, tanks, planes, bomb fuses, cases for shipping shells, insulators...
...Lignin plastics are the cheapest plastics yet devised; at 5? per lb. for the powder they cost only one-third to one-fourth the cost of most synthetic resins. But today they have a still greater advantage-they require as little as 2 or 3% phenol (carbolic acid), a chief component of the commonest plastics and now a badly needed, priorities-listed ingredient. Furthermore, lignin molding powders can be mixed to "extend" phenol plastics by 100%, synthetic rubber for many uses by 100 to 500%. This aspect of lignin was last week under intensive study by the U.S. Army & Navy...
...road-binding material, lignin is widely used in New Jersey and Washington instead of tarry binders. This use was developed in the U.S. about 1905 by Jacob Robeson, pioneer industrial student of lignin. Robeson Process Co., unlike Marathon, removes lignin from pulp wastes by evaporation rather than by precipitation...
