“…In wet milling oil extraction, about 5-8 tons of water are consumed for every ton of crude palm oil produced; more than 50% of this water ends up as effl uent 2 . Nearly 55×10 6 m 3 of palm oil mill effl uent is generated from the palm oil industry every year 3 . Of this, 48000 mg/L is solids commonly known as palm oil mill effl uent sludge 4 .…”

The objective of this work is to evaluate the removal of methylene blue dye by bio-polishing sludge-based adsorbents. The adsorbents were characterized according to the specifi c surface area, pH upon the treatment and surface functional groups. The adsorption of dye was carried out at room temperature, and the adsorption data were analyzed using the isotherm and kinetics models. The bio-polishing sludge is rich in ash content, and the presence of surface functional groups varied with the treatment strategies. The specifi c surface area of adsorbents is between 7.25 and 20.8 m 2 /g. Results show that the maximum removal of methylene blue by sludge adsorbents was observed to have the following order: untreated sludge (SR) > zinc chloride-treated (SZ) > microwave-dried (SW) = potassium carbonate-treated (SK) > acid-washed (SH). The maximum adsorption capacities for SR and SZ as predicted by the Langmuir model are 170 and 135 mg/g, respectively. Although SR demonstrates a higher maximum removal than SZ, the latter exhibits greater removal intensity and rate constant even at high dye concentration. The bio-polishing sludge is a promising adsorbent for dye wastewater treatment.

“…Compared to POME 1, POME 2 exhibited higher levels of solid residues, at 67,750 mg/L. This is because before the clarification process, the palm fruits were subjected to several harsh mechanical processes such as bunch stripping, digestion, and pressing (Ujang et al 2010). In fact, the CPO was deposited in the mesocarp of palm fruits, meaning that the fruits needed to be crushed and pressed for maximum oil extraction.…”

The production of palm oil requires a large amount of water, which subsequently turns into wastewater known as palm oil mill effluent (POME). Because of its high organic content, there has been debate over how to utilize POME for oil recovery. POME is usually mainly comprised of water (95 to 96%), total solids (4 to 5%), suspended solids (2 to 4%), and oil (0.6 to 0.7%). The lignocellulosic particles in POME are highly oleophilic and capable of absorbing oil. Therefore, the objective of this study was to understand the presence of residual oil and try to relate with the oil loss in POME and to identify the solid particles in POME and their correlations. Microscopic observations showed that most of the oil droplets available in POME were less than 100 µm in size. If given the opportunity to settle, the highest quantity of oil droplets and solid particles was in the bottom layer, followed by the middle layer, and lastly the upper layer. In cases where the contact angle of water was less than 45° on POME solids, the absorption rate was 0.11 ± 0.03 µL/s and 0.09 ± 0.01 µL/s, respectively. This study concluded that the oil losses in POME were partly due to the absorption of oil by the fibers.

Agricultural waste management for horticulture revolution in sub-Saharan Africa

et al. 2020

Agricultural activities, which basically involve the production of raw produce and subsequent value addition normally, generate substantial waste, which could be in solid, liquid or gaseous forms. In sub-Saharan Africa (SSA), the disposal of these wastes, which come from a myriad of sources or agricultural activities, constitutes a huge challenge. Even though these wastes are economically viable when properly managed by conversion to organic fertilizer and eventual use in crop production, they often exert hazardous effect on the environment due to improper disposal or management. Properly managed wastes deployed in conservation agriculture could enhance ecological balance and ensure sustainable crop production system intensification leading to elevated levels and quality of yield. Positive utilization of these wastes holds great prospects for SSA, which is characterized by accelerated population growth that puts undue pressure on available land, declining soil fertility and crop yield as well as high rate of youth unemployment. Horticulture essentially involves intensive cultivation of specialty crop (fruits, vegetables, ornamentals, seedlings) and, thus, often pays special attention to soil fertility management. The crops are largely grown under protected environments (modified or controlled environments), consequently, requiring among other variables high soil/ substrates fertility. Organic manure generated from agricultural wastes is a putative source of good-quality and cheap nutrients for optimum crop performance. Converting large volume of available agricultural wastes in SSA to organic manure for horticultural field production and/or to organic substrates for protected crop production and commercial nursery will revolutionize horticultural industry in the subregion. This review explores the various types of agricultural wastes generated in SSA, their possible or potential utility in the horticulture industry and advocates their proper management and utilization in horticulture to enhance environmental quality, increase crop yield and quality and improve economies and livelihoods across SSA.
