“…Since POME has currently little or no recycling value, it constitutes an environmental hazard, undergoing slow (acidic) degradation in pits from which it emits strong, foul odour causing air pollution and contamination of ground and surface waters and agricultural land besides vector attraction. Attempts have been made to achieve valorization of POME through production of microbial biomass, enzymes, energy, and biochemicals [27][28][29][30][31][32][33][34][35][36][37][38].…”

Palm oil mill effluent (POME) is high strength wastewater derived from processing of palm fruit. It is generated in large quantities in all oil palm producing nations where it is a strong pollutant amenable to microbial degradation being rich in organic carbon, nitrogen, and minerals. Valorization and treatment of POME with seven yeast isolates was studied under scalable conditions by using POME to produce value-added yeast biomass. POME was used as sole source of carbon and nitrogen and the fermentation was carried out at 150 rpm, 28 ± 2°C using an inoculum size of 1 mL of 106cells. Yeasts were isolated from POME, dump site, and palm wine. The POME had chemical oxygen demand (COD) 114.8 gL−1, total solid 76 gL−1, total suspended solid (TSS) 44 gL−1and total lipid 35.80 gL−1. Raw POME supported accumulation of 4.42 gL−1dry yeast with amino acid content comparable or superior to the FAO/WHO standard for feed use SCP. Peak COD reduction (83%) was achieved with highest biomass accumulation in 96 h usingSaccharomycesspL31. POME can be used as carbon source with little or no supplementation to achieve waste-to-value by producing feed grade yeast with reduction in pollution potential.

“…Similar findings also revealed that a 70:30 ratio of POME to cow manure could produce a methane content of 35.35% over 28 days of digestion [59]. POME has also been co-digested with other feedstock, such as empty fruit bunch (EFB), decanter cake, rumen fluid, and refined glycerine wash water [60][61][62][63].…”

Palm oil is one of the leading agricultural crops in the world, as it dominates 34% of the global vegetable oil market, with approximately 64.6*103 million kgs of production in 2017. However, along with its breakthrough, the generation of palm oil mill effluent (POME) as uncontrolled waste has become a serious matter and requires proper management to reduce its negative effects on the environment. Subsequently, the high organic content of POME makes it possible to convert waste into value-added products, such as biogas. A ratio of 0.5 for biological oxygen demand to chemical oxygen demand (BOD/COD) indicates a high possibility for biological treatment. Recently, the utilisation of POME as a cheap source for biogas production has gained an extraordinary amount of attention, and intensive research has been conducted on the upstream to downstream process. Finding the most suitable and efficient pretreatment technique and reactor configuration are vital parameters for the treatment and conversion of POME to biogas. This review describes existing pretreatment processes for POME and recommends recently manufactured high-rate anaerobic reactors as the most suitable and efficient pretreatment technique for maximising the extraction of biogas from POME.

“…Approximately 50% of the water utilized results in POME. For every ton of crude palm oil extracted from milling, about 2.5 tons of POME are generated (Sulaiman et al, 2009). Raw POME has a very high organic content and if discharged into receiving waterways, has the potential to cause adverse environmental consequences.…”

Problem statement: Palm oil milling generates solid wastes, effluent and gaseous emissions. The aim of this study is to assess the progress made in waste management by the Malaysian palm oil milling sector towards the path of sustainable development. Sustainable development is defined as the utilization of renewable resources in harmony with ecological systems. Inclusive in this definition is the transition from low value-added to higher value-added transformation of wastes into resources. Approach: A longitudinal study was carried out from 2003-2010 via, initially a field survey and subsequently a key informant approach with observation as a complementation for both. Results: Solid wastes, inclusive of solid wastes derived from air emissions and palm oil mil effluent, have a utility function with zero wastage. The principal source of effluent is palm oil mill effluent. Treated palm oil mill effluent is utilized for cropland application by plantation-based palm oil mills. However, independent mills discharge treated palm oil mill effluent in accordance to environmental parameters into receiving waterways. Methane is also released by palm oil mill effluent. Biogas from palm oil mill effluent and biomass energy from solid wastes are potential sources of renewable energy in Malaysia. Conclusion: In general, the wastes from palm oil milling are returned to the field for cropland application, utilized in-house or in the plantation, or sold to third parties. Thus, there is progress made towards sustainable development. The addition of new technologies and replacement of old mills will help to reduce the carbon footprint. However, at this juncture, the feed-in tariff for renewable energy is not financially attractive. If the biogas and biomass renewable energy sector were to take-off, enhancement in the value chain would occur and in tandem further progress towards sustainable development can be attained.
