Show i WEALTH IN oM WASTE NEW DISCOVERY FOR MAKING WOOD PULP PAPER Invention of a Minnesota Professor by Which Product Worth 750 Is Made to Yield SQLlke Distilling Sugar Minneapolis Minn One of the most fitgnlllcant Industrial discoveries of tho age was admitted the other day by Dean George B Frankforter of the college of chemistry of the University of Minnesota It means says experts that the United States will produce a hundred times as much wood pulp paper as was believed possible It moans that every cord of llr lumber will yield ten dollars dol-lars profit on byproducts alone and that the greater part of the 60 percent per-cent of a tree now wasted will be turned Into dollars and cents It means huge plants and now Industries A prominent lumberman Is almost the solo sharer with Dr Frankforter of the process So convinced Is he of the enormous commercial value of the discovery that an experimental plant will be constructed this summer In the west to be followed Immnillntnlv Iw 0 the building of a mammoth plant Dr Frankforter has experimented on these processes for 12 years The perfected per-fected process consists of taking small pieces of waste wood or sawdust layIng lay-Ing It on a steel Incline over a furnace and subjecting It to a chomlcal process of distillation Carbon dlsulphlde or gasoline Is poured over the sawdust dlsolvlng the turpentine and resin which pass off as gases Into a call of pipes leading to a tank The process Is similar to the distillation distilla-tion of sugar Wood pulp remains free from pitch nnd eminently suitable for the manufacture of paper The existing exist-ing method of distillation left the pulp In the form of charcoal Dr Frank fortor extracted from one cord of Nor way pine worth 750 turpentine worth 4100 and wood pulp worth 39 or a yield of 80 from 750 worth of raw material Tho story of tho discovery rends like a story book Walking one day In 1890 through the pine woods of the northern north-ern part of Minnesota Dr Frankforter noted an old stump which gave out an odor strangely unlike that of the ordinary or-dinary turpentine lie took a sample back to tho university showed It to a friend In the faculty who happened also to ho a friend of Weyerhaeuser and mentioned his desire to experiment experi-ment further Within a week a milk can filled with the pitch of the Norway Inotor It was that which he had taken home was sent him He set to work Tho then known process of distillation consisted In boiling the wood until tho pitch was separated and the wood left as charcoal Neither of those substances sub-stances had much commercial value Ho then happened upon the present process Later ho erected a small experimental ex-perimental plant near his home and capitalists Interested came to his assistance as-sistance The discovery of the process of making wood pulp mute like a flash |
