Typically,<B> bagasse pulp</B> is produced in integrated pulp and paper mills, and softwood kraft or sulfite pulp is added to provide the strength requirements to the paper. However, specialty nonwood pulp may be used instead of softwood kraft or sulfite pulp thus producing a 100% nonwood paper. The possible combinations are endless and can be adjusted to meet market requirements.  </div> <bR> <div> Furthermore, it is possible to add small quantities (up to 20 - 30%) of <B>bagasse pulp </B>to primarily woodpulp-based papers without impairing paper properties or paper machine runnability. This provides wood-based mills which are hardwood deficient but located within a region with available <B>bagasse</B> resources with the option of adding-on a straw pulping line to supplement their fiber requirements.</div> <bR> <div> The following table provides some uses for <B>bagasse pulps</B> in papermaking. It is by no means complete as many other products could be added to the table. Rather this table provides an indication of the many possibilities which are available for the use of <B>bagasse fiber</B> in papermaking. When reviewing this table, please note:</div> <bR> <div> <IMG BORDER="0" SRC="Symb075c00b7010411111100.png" HEIGHT="17" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">The bagasse pulp in the furnish is chemical pulp unless noted otherwise.</div> <div> <IMG BORDER="0" SRC="Symb075c00b7010411111100.png" HEIGHT="17" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">The long fiber pulp typically would be kraft or sulfite chemical pulp (or a mixture of the two) made from softwoods, and bleached, semi-bleached or unbleached depending on the type of paper or paperboard.
