Characterisation Of The Alkaline Peroxide Pulps From The Oil Palm Empty Fruit Bunch And Their Potential For Cellulose Acetate Production

The first phase of this study involved the making and analyses of hand sheet made from the fibers of the oil palm empty fruit bunches via the process called the alkaline peroxide pulping (APP). This was followed by a two-stage paper recycling process Eight sets of hand sheets were made from the fibe...
