“…The widespread use of these ponds is justified by low initial investment, minimal technical requirements, and reduced operational costs [ 21 ]. Management techniques are being analyzed to develop affordable and effective methods, with the goal of effectively reducing chemical oxygen demand (COD) and BOD [ 22 ]. Among these techniques, low-cost unconventional methods stand out, which include microbial degradation processes, physicochemical coagulation processes, membrane filtration, and thermochemical procedures [ 23 ].…”

Palm oil derived from the fruits of Elaeis guineensis Jacq. has global economic importance and is largely produced in tropical regions. The palm oil production process leads to a highly polluting waste called palm oil mill effluent (POME). A strategy commonly used by producers to overcome environmental issues and to improve soil fertility is the reuse of POME as a fertilizer due to the chemical and biological characteristics of the effluent. In this research, three groups were analyzed: soil without POME application (control group) and soil samples after 4 and 9 days of POME application. An environmental DNA metabarcoding approach was used. eDNA was extracted, and the V4 region of the 16S rRNA gene was amplified and sequenced in the Illumina MiSeq platform. The abundance of Proteobacteria (48.1%) and Firmicutes (9.0%) was higher in fertilized soil, while Bacteroidetes (20.3%) and Verrucomicrobia (7.8%) were more abundant in control soil. Additionally, the effluent seemed to modify soil characteristics favoring taxa responsible for the mineralization of organic compounds and nitrogen fixation such as species of Gammaproteobacteria class. Our study highlights the influence of POME on soil biological components and contributes to the sustainable production of palm oil in the Amazon.

“…Palm oil mill effluent (POME), the side product from the process is abundant and it will emit more air pollutants if they are not treated correctly . The substantial quantity of POME currently poses an environmental hazard, necessitating the implementation of an appropriate treatment process to mitigate its organic potency in compliance with prescribed discharge thresholds before its release into the environment [ 20 ]. POME can be treated by using an anaerobic biofilm reactor, composting and biogas production.…”

“…The recent improvement in the treatment of POME using anaerobic biofilm reactors is reviewed in a study [ 20 ]. The study summarizes that the anaerobic biofilm system has the ability to create high-quality effluent in compliance with the standard discharge constraint and allow the generation of the biogas which is a value-added product.…”

“…This industry has led to the vast production of POME accounting up to 30 million metric tons per year [2]. Large volume of POME can be a threat to the environment if released directly, therefore, effective treatment system like anaerobic digestion is recommended to reduce the organic matter in POME [12]. Meanwhile, the production of palm oil also produces a great amount of oil palm biomass waste which then incinerated to support the power plant creating ash known as palm oil fuel ash (POFA) [4,5].…”

Anaerobic digestion is a favourable technology for the treatment of palm oil mill effluent (POME) and production of biogas. Biological treatment using an anaerobic batch reactor (ABR) augmented with palm oil fuel ash (POFA) was implemented to investigate the impact of POFA on their performances. Two ABRs are fabricated in this study: Control and POFA ABRs, where POFA ABR was operated at 2g/L of pre-treated POFA with potassium hydroxide (KOH) to increase its porosity. Both reactors are kept at room temperature and a daily feed with neutralized raw POME. Treated samples were collected daily to test for chemical oxygen demand (COD) and pH, whereas weekly tests for mixed liquor volatile suspended solids (MLVSS). Results showed that the control ABR is able to reduce up to 94.4% of COD as compared to the POFA added ABR with only 63.3% in 50 days. The addition of POFA into the anaerobic digestion resulted in lower performance in terms of COD removal efficiency by 20.5%. Economic analysis evidenced that with 85,500 m3 of POME, up to 863 tons of biomethane can be produced, showing a large amount of energy can be utilized from the anaerobic digestion of POME as an alternative energy source.
