The reduction of the energy consumption in papermaking process become more important issue because of the regulation of green house gas (GHG) emission. Since more than half of energy for papermaking process is consumed during drying process, the increase of the drying efficiency would be very important solution for saving energy and reduction of GHG emission. The improvement of drying efficiency could be very difficult for the liner board mill because the liner board are usually made of recycled paper, OCC (old corrugated container). The short fiber and fines originated the OCC lead to compact sheet structure and delay the water flow out during wet pressing process and drying process. The application of lignocellulose spacer could provide more loose wet sheet structure and result in the higher drainage rate and the improved drying efficiency. In this study, the effects of the application of lignocellulose spacer to the liner board mill were evaluated based on the mill trial. In order to overcome the common disadvantage of the spacer, the loss of strength properties, the spacer was pretreated with amphoteric polyelectrolyte during mill trial. The results showed the application of pretreated spacer improved the drying efficiency by reducing steam consumption. And the loss in the strength properties by the spacer could be supplemented by the pretreatment.

The application of conifer leave to the papermaking process as a functional organic filler was investigatedin this study. The powder of the conifer leave after hot water extraction for the functional extract, suchas phytoncide, was applied to OCC stock. The comparison between the commercial wood flour and theconifer leave powder as organic filler for OCC paper were conducted with various wet pressingconditions. The amount of the water removal by the wet pressing process and the bulk of handsheet wereincreased by the addition of the wood flour and the conifer leave powder, although the tensile strengthwas decreased. At the higher pressure condition of the wet pressing, the wet pressing efficiency wasgreatly increased by the wood flour and the conifer leave powder. There was a little difference in the performanceof the wood flour and the conifer leave powder as an organic filler. Those results showed theconifer leave powder could be an alternative resource to the wood powder for papermaking organic filler.
