Acid activated carbon obtained from cheap, non-toxic and locally available banana peel was used as a low cost and efficient adsorbent for the removal of dyes methyl orange and rhodamine-B from the aqueous solution. Changes in the resulting material before and after activation and after treatment were studied by different techniques, such as SEM-EDX, XRD, FTIR measurements. Effects of duration of treatment, amount of banana peel activated carbon, pH, and initial methyl orange and rhodamine-B concentration, on the removal of dye were studied to get optimum conditions for maximum dye removal. Removal efficiency of the activated ash remains almost constant in a wide range of pH from 2.5 to 5.6. In 75 min at room temperature removal of 98.5 % methyl orange (anionic) and 99.0 % rhodamine-B (cationic) dyes with 0.1 g and 0.125 g, respectively was obtained from the contaminated water having 10 ppm dye concentration.

Contamination of metals in aquatic environment is a worldwide problem because of its toxicity and capability to accumulate in biological chain, as well as persistence in the natural environment. Therefore various expensive technologies have been applied to treat metal-polluted water. In Malaysia there are abundance of banana species available which could provide cheap, low cost and environmental friendly bio-materials. Preliminary study was conducted on two species of banana i.e. Musa balbisiana (Nipah) and Musa acuminata (Kapas). The banana peels were washed, dried and grounded into various range of particle sizes (0.20–1.18 mm). The ability of the adsorbents were determined by agitation of 1.0 g banana peel and 100 ml of cadmium standard solution at the concentration of 100 mg/L. Musa balbisiana showed the highest removal of cadmium at 89.58% from the initial concentration compared to Musa acuminate with the particle size of 0.30-0.60 mm. Adsorption equilibrium data are well described by Langmuir isotherm model. The result also shows that different species have different capabilities to adsorb metal. Hence, their potential as bio-adsorbent could be further be examined for metal removal from wastewater.

Abstract In this study nutritional values and seasonal availability of 43 local feed ingredients for pigs in Uganda, were estimated based on nutrient analyses and literature values, information needed to develop low-cost balanced rations for pigs on smallholder farms. Parameters considered were: concentration of ash, neutral detergent fibre (NDF), crude protein (CP), calcium (Ca), phosphorous (P), ether extract (EE), total lysine (Lys), standardized ileal digestible (SID) Lys, standardized total tract digestible (STTD) P (all as % of dry matter [DM]); digestible energy (DE), (kcal kg−1 of DM); and DM concentration. Concentration of DE, total Lys, SID Lys, and STTD P were estimated. Ingredient seasonal availability and relative importance were identified. Ground sun-dried fish (Rastrineobola argentea) had highest estimated DE concentration and Napier grass (Pennisetum purpureum) had lowest (4209 and 535 kcal kg−1 of DM, respectively). Ground sun-dried fish had highest CP and estimated total Lys concentration (59.9 and 6.7% of DM, respectively) and banana peel (Musa sapientum), had lowest (5.21 and 0.08% of DM, respectively). Milled ingredients sampled here had higher ash than in the literature (e.g. ground sun-dried fish 58.1 vs 15.9% of DM) likely indicating sand contamination. There were 3 seasons of availability of ingredients. Banana peel, maize bran, and sweet potato vine (Ipomoea batatas) were ranked highest; and commercially-prepared ration, and kale/collard greens (Brassica oleracea var. acephala), were ranked lowest as potential feed ingredients. Ingredients with nutritional profiles suitable for pigs are available but some only in certain seasons. Estimated nutritional values may assist in ration formulation.

Nowadays due to the depletion of non-renewable energy resources, production of green material from domestic wastes has played an important role. The waste of banana peel impregnated with calcium oxide (CaO) from eggshell had successfully been used as a low-cost catalyst to transesterify soybean oil to produce methyl ester. The catalytic actions from potassium and calcium oxide content in calcined banana peel (700°C) and eggshell (900°C) discover through FT-IR, XRD, and SEM. Methyl ester conversion can be obtained at 76.87 wt.% with the optimal condition of 7 wt.% of catalyst amount, methanol/oil mass ratio, 9:1; and the reaction temperature, 65 °C within 2 h reaction time.

Application Potential

Liquid-phase adsorption removal of Cu2+, Co2+, Ni2+, Zn2+, and Pb2+ in the concentration range of 5-25 mg/L using low-cost banana and orange peel wastes was examined at 30 oC. Under comparable conditions, the amount of adsorption decreased in the order Pb2+ > Ni2+ > Zn2+ > Cu2+ > Co2+ for both adsorbents. The adsorption isotherms could be better described by the Freundlich equation. The amount of adsorption increased with increasing pH and reached a plateau at pH > 7, which was confirmed by the variations of zeta potentials. The application potential of such cellulose-based wastes for metal removal (up to 7.97 mg Pb2+ per gram of banana peel at pH 5.5) at trace levels appeared to be promising.

AbstractThe paper addresses an exploration of the removal efficiency of banana peel ftrip(BP) towards copper and zinc ions from water and to optimize the factors involved in this adsorption process. In this sense, process optimization, kinetics, and equilibrium studies were performed in a batch process. The kinetics shows that the equilibrium reached in 60 minutes and the adsorption is favored above pH 5. The BP was firstly characterized by proximate analysis, FTIR, BET surface area, and SEM. The highest adsorption capacity for Langmuir isotherm for Cu(II) and Zn(II) onto BP was observed to be 61.728 mg/g and 55.56 mg/g respectively. Finally, the regeneration of BP was also studied up to 5 cycles. Thus, BP showed excellent adsorption characteristics during the uptake of Cu(II) and Zn(II) from wastewater effluent and can be used as low-cost agricultural waste biomass as an adsorbent.

The Impact

Water pollution is considered a perilous issue that requires an immediate solution. This is largely because of the strong correlation between the global population increase and the amount of waste produced (most notably food waste). This project prompts the conversion of food waste into useful materials that can be used with sodium alginate as a catalytic support for metal nanoparticles. Sodium alginate/banana peel (Alg/BP) beads were prepared simply using an eco-friendly method. The prepared materials were modified using nanostructured materials to enhance their characteristics. Alg/BP beads were employed as adsorbents for metals that were then treated with sodium borohydride to produce MNPs@Alg/BP. Different MNPs@Alg/BP (MNPs = Ag, Ni, Co, Fe, and Cu) were used as catalysts for reducing 4-nitrophenol (4-NP) by NaBH4 to evaluate each catalyst performance in a model reaction. The results exhibited that Cu@Alg/BP was most efficient toward complete transformation of 4-NP. Therefore, Cu@Alg/BP was also used as a catalyst for the reduction of potassium ferricyanide, congo red, methyl orange (MO), and methylene blue. It was found that Cu@Alg/BP beads catalytically reduced up to 95–99% of above pollutants within a few minutes. Cu@Alg/BP beads were more selective in reducing MO among the pollutants. The catalytic activity of Cu@Alg/BP was examined by evaluating the impact of numerous parameters on MO reduction. The results are expected to provide a new strategy for the removal of inorganic and organic water contaminants based on efficient and low-cost catalysts.
