Wood Flour Opens New Field for Industry. Industrial plants in the United States are developing over night new uses for wood flour, according to the National Committee on Wood Utilization of the qepartment of Commerce. Wood plastics of the type that can be pressed or molded are now working into specialized fields, where apparently their use is meeting an economicabapproval. Only recently have wood plastics entered the furniture and other industries.

The committee stated that i t is impossible t o tell exactly the amounts of wood flour consumed bv various industries. Phenol-resin products. linoleum and its use in dynamite cartridges as filler consume many thousands of pounds yearly. The increasing demand for wood flour in the manufacture of various articles has resulted in an increased consumption of thr product from 7000 tons in 1924 to 21,OUO ton.. ill 1%:. and nppro~i- matclv 40.000 tons in 1!l28. Uurina 1928 imports of wood flour into the I'nited 3utes . . totaled 14,490,401 pounds, valued a t 594,723, i t was stated.

It was pointed out by the committee that whereas American operators are spending money to dispose of sawdust and shavings, European lumber manufacturers are con- verting these materials into wood flour, exporting i t to this country, paying duty, and evidently selling it a t a profit. European wood flour hss been claiined to have certain advantages over the domestic product, but the validity of the claim has been disproved, it was stated. Increased experience and care in the selection of raw material by American manufacturers have resulted in a product equal in every way to that produced by foreign mills, according to the committee.

The wwd substance of various species of trees differs very little in composition, i t was explained. However, there are certain infiltrations of gums and resins in some woods, and in others certain coloring, that preclude their use as wood flour for some products.

Spruce, fir, and pine are the chief woods used in Europe to produce the highest grades of wood flaur. Similar species are represented in the United States by true firs, white pines, and spru-.-Ind. Eng. Chem.
