PULP WOOD FROM WASTE

Professor Frankforter of University of Minnesota Makos Discovery of Importance. St. Paul. Minn.—Prof. George Ti. Frankforter, dean of the College of Chemistry of the Minnesota State university, has announced the details of a discovery made by him by which, he declares, through the utilisation of waste wood and sawdust the United States will produce one hundred times more pulp wood than was believed possible. “It means,” he says, “that every cord of fir lumber will yield $lO profit on by-products alone, and that the greater part of the 60 per cent, of a tree now wasted will be turned Into dollars and cental Professor Frankforter predicts that huge plants will be built as the result of his discovery and that the new industry will assume proportions of great magnitude. • C. A. Smith, of the C. A. Smith Timber company. Is interested with Professor Frankforter in the process. So convinced Is he of the enormous commercial value of the discovery that an experimental plant Is now being constructed. and a mammoth plant is already planned, to he erected la the far west

Doctor Frankforter has experimented on his processes for twelve years. The developed process consists in taking small pieces of waste wood or sawdust, laying them on a steel incline over a furnace, and subjecting them to a chemical process of distillation. Carbon disulphide or gasoline is poured over the sawdust, dissolving the turpentine and resin, which pass off as gases into a coil of pipes leading to a tank. The process is similar to the distillation of sugar. The wood pulp remains, free from pitch and suitable for the manufacture of paper. The present method of distillation leaves the pulp In the form of charcoal.
