WASTE KAURI WOOD.
AND PAPER-PULP MAKING. The feasibility of converting tk. waste wood that is obtained from the kauri tree to commercial advantage is receiving the consideration of the Imperial Institute, London, which, in its annual report, supports the suggestion that it sould be used for the manufacture of paper pulp. The text of the report is as follows: “In the kauri timber of New Zealand a large amount of waste wood is obtained, and the possibility of utilising it for paper-making is under consideration. At the request of the Forestry Department in New Zealand, the Imperial Institute has examined samples of the waste wood in order to determine the yield and quality of the pulp which it will furnish. The wood contains varying amounts of resin, and a further investigation has been carried out to ascertain the nature and value of this resin and whether it would be profitable to remove it from the wood before pulping. “The results of the paper-making trials showed that the kauri wood, cither in its original condition or after the removal of the resin, could be converted into paper pulp of satisfactory quality. If the wood contains over 10 per cent, of resin it might be advantageous to remove the latter before pulping, but when less than this quantity is present the wood might be converted into pulp without previous deresinarion.
“A quantity of the resin was extracted from the wood and, after examination in order to determine its nature and properties, samples were submitted to likely users. It seems probable that the resin would be marketable in this country, but technical trials on a larger scale would have to be made by manufacturers in order to determine definitely its commercial value and possibilities. ’’Full reports on the entire investigation, together with specimens of u-per prepared in the laboratories from ■ ach of the samples of wood, have been :orwarded to New Zealand in order that he question may be further considered by the Forestry Department,,^
