Abstract
Palm oil is one of the biggest commodities in tropical countries. Its massive production generates palm oil mill effluent (POME) as waste. Due to its high concentration of organic matter, POME should be processed before being released. One of the most promising methods for processing POME is anaerobic digestion (AD). AD is widely known as a sustainable technology implemented in various industries for processing their organic waste. Tropical countries prefer the AD process which operates under mesophilic conditions due to its similarity with tropical room temperature. Several studies on thermophilic AD of POME have found high methane concentrations, up to 77.33%. Future research should highlight the advantages of thermophilic AD, which are totally worth the tedious temperature control operation.
