Mar 10, 2017 · The accelerated composting time and improved compost quality can make composting a more attractive option for palm oil mills, with economic and environmental benefits. The study also aimed to determine the importance of composting to reduce the emission GHG, which is generated abundantly from open EFB dumps and POME treatment ponds.
Oct 22, 2014 · Approximately 420 oil palm mills in Malaysia handle with the quantity of waste created in the palm oil extraction process. About 5.5 t of fresh fruit bunch (FFB) are needed by palm oil mill for extraction of 1.0 t crude palm oil. The wastes generated are 28 % EFB, 24 % fibres, 6 % shell, 3 % DC and POME.
2.3 Waste management and composting in the life cycle of palm oil studies published in peer review journals or Besides the land use change impact, the main sources of environmental impact from palm oil production on mineral soils are the treatment of Palm Oil Mill Effluent [POME] in the mill, the use
Mar 7, 2020 · Abstract Large amounts of palm oil consumption in Malaysia leads to large amounts of by-products such as Empty Fruit Bunch (EFB) and Palm Oil Mill Effluent (POME) requiring disposal. Limited treatment for these waste products has resulted in interest to use EFB + POME in composting when mixed with different biomass sources for nutrient enhancement. This work is aimed at enhancing the
Mar 25, 2016 · Table 1 Nutrient content of empty fruit bunch from oil palm. Full size table. Palm oil mill effluent (POME) is colloidal suspensions that contain 95–96 % water, 0.6–0.7 % oil and 4–5 % total solids including 2–4 % suspended solids (Singh et al. 1999 ). It generated from the final stage of palm oil processing where it consists of washing
Jun 8, 2020 · Mamimin and co-authors examined the kinetic of co-digestion of POME with various types of oil palm biomass in two-stage anaerobic system, the lag phase for biomethane profile in POME sample was 0.
Oct 15, 2023 · During composting, pH is a crucial indicator of microbial activity and population composition [51].The variation in pH values during composting is also shown in Fig. 1.At the start of the composting process (Day 0), the pH of BPA pile mixture was 4.3, known to be due to food waste acidification, which produces organic acids as well as some volatile acids of low-molecular-weight
Mar 15, 2021 · Antibiotic resistance genes (ARGs) have been diffusely detected in several kinds of organic solid waste, such as livestock manure, sludge, antibiotic fermentation residues, and food waste, thus attracting great attention. Aerobic composting, which is an effective, harmless treatment method for organic solid waste to promote recycling, has been identified to also aid in ARG reduction. However
Previously, a unique co-compost produced by composting empty fruit bunch with anaerobic sludge from palm oil mill effluent, which contributed to establishing a zero-emission industry in Malaysia. Little was known about the bacterial functions during the composting process and fertilization capacity of this co-compost.
Dec 15, 2021 · All targeted seven ARGs and four MGEs were detected in the PFR co-composting process. Fig. 1 shows the variations in absolute abundances of ARGs during composting. In the fermentation residue samples, the total number of copies of seven target ARGs was 2.31 10 8 –3.75 10 11 copies/g, and the mean number of copies was 1.79 10 9 copies/g.
Feb 1, 2018 · The aim of this research was to produce the oil palm empty fruit bunch (EFB) compost for ornamental plant cultivation. EFB co mpost was produced by c hopping fresh EFB. into 1 -3 c m piec es
