Enhancing thermophilic methane production from oil palm empty fruit bunches through various pretreatment methods: A comparative study.

ABSTRACT: This study investigated the effects of various pretreatment methods on the anaerobic digestibility of oil palm empty fruit bunches (EFB) for methane production. Pretreatment methods included weak alkaline (2 % Ca(OH)₂), weak acid (2 % acetic acid), acidified palm oil mill effluent (POME), biogas effluent, hydrothermal (180 °C, 190 °C, and 200 °C), and microwave pretreatments. All pretreatment methods enhanced methane yield compared to untreated EFB (189.45 mL-CH₄/g-VS), with weak alkaline pretreatment being the most effective (277.11 mL-CH₄/g-VS), followed by hydrothermal pretreatment at 180 °C (244.33 mL-CH₄/g-VS) and biogas effluent pretreatment (238.32 mL-CH₄/g-VS). The enhanced methane yield was attributed to increased cellulose co
