Hurter, P. Eng., MBA, President, HurterConsult Incorporated, April 2002.</div> <bR> <div>  <a href="HTMLobj-896/nonwood_paper_1.pdf"><img align="bottom" border="0" width="153" height="17" alt="Nonwood Fiber Content Papers - Part 1: Corrugating Medium" src="HTMLobj-896/download_pdf_LG_LARGE.gif"></a>  (requires Adobe Reader).</div> <bR> <div> The data contained in the following table is from an excellent paper entitled "Industrial Experiences & Problems Involved In Stock Preparation & Papermaking Utilizing Non-Wood Fibrous Materials", written by D.K. Misra, Thessalian Pulp & Paper Industries Ltd., Larisa, Greece, and published in 1975 in the TAPPI Non-Wood Plant Fiber Pulping Progress Report No. 6.</div> <bR> <div> This data was developed from tests on commercially produced paper and paperboards which were available at the time. Some of this data likely is a little outdated due to advancements in paper machine design such as improvements in Fourdrinier drainage and the development of twin wire paper machines and no-draw press sections, all of which allow for a high nonwood fiber fraction in the furnish. Nevertheless, this actual mill data still offers a valuable insight into the potential use of nonwood fibers in papermaking.  </div> <bR> <div> Unfortunately, since this paper was presented, no one has undertaken a similar ambitious project to determine the characteristics of currently available nonwood fiber content papers. With the renewed interest in nonwood fibers for papermaking in North America and Europe, perhaps the time has come for a research organization to undertake such a project.</div> <bR> <div> The following table provides physical properties of <B>corrugating medium</B> produced from nonwood pulps. Even using pre-1975 technology, a few points to consider include:</div> <bR> <div> <IMG BORDER="0" SRC="Symb075c00b7010411111100.png" HEIGHT="17" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">the
