The conventional process is unable to partly dissolve the lignin and ex/ractives effectively, and consequently produces EOPB pulp with undesirable results, i.e. low screened yield, poor qualities, and longer defiberation and fibrillation duration. As one way to cope with it, the EOPB prior to the soda anthraquinone (AQ) semi-chemical pulping should be pretreated by biodelignification.In this regard, the EOPB chips were biodelignified through the inoculation of the raw materials with the Cipanas-strainfungi (CPSOI) as much as 5-and 10-percent (oven dry weight), and further incubated for I0-and 20-days. Afterwards, the fungi-treatedchips were semi-chemically pulped using the soda-AQ process into newsprint pulp after they are cooked in an electrically heated digester. After the cooking, the EOPB chips were defiberized in a Hollander beater, stone-refined, and then fibrillated in a Niagara beater into ultimately the EOPB pulp with the degree offreeness at 300 CSF.

contents Empty oil-palm bunches (EOPB), due to high contents of lignin (24.68 percent) and extractives (5.57 percent), is less economical when it is pulped using the conventional semi-chemical or semi- mechanical process into newsprint pulp.
