Small-scalepaperboard industriesin Indonesia are mrrentfyfaced with theptvcumnent continuity offibrous raw nyaterial(partim/arfypulp and wastepaper).Wastes ofpal11J-oil processing as e11Jpty oil-palmfruit bunches (EOPFB),inherentfy ligno-cellulosicfibers,are abundantfy available;and asyet have not been utilized comnyercialfy,hence indicating their potential uses as raw materialfor suchpaperboard industries.In relevant, the BO PFB has been experimentally pt1lped usinghot soda semi-chemicalprocess i11 the se11Jipilotscale closed (pressurized)digester, emplf!Ying thefixed cooking condition, i.e. soda (NaOH) concentration 10%, EOPFB toliquor ratio 1:5.5,and maximto temperaf11re 120 'C held for 2 hours. This digester serves as a part of eqnipmenf etnpl(!)led in S11Jall-scalepaperboard manufacttlre.The EOPFB pt1lpyield reached 60.17%.
