“…In all the cases of calcined waste banana residue-catalyzed transesterification reactions, the biodiesel conversion routinely reached >95% except for a study by Ma'arof et al (2021) who obtained a conversion of 76.87%. 43 All the banana residues contain potassium element as the main component. However, the concentration of potassium did not significantly affect the biodiesel conversion.…”

“…Presently, heterogeneous catalysts derived from agricultural waste biomass such as banana peel, banana peduncle/trunk, cocoa pod husk, walnut shell, passion fruit peel, coconut husk, palm bunch ash, and more ,− have been introduced and proven to have catalytic activity comparable with a homogeneous substance . For instance, our previous research showed that calcined waste passion fruit peel could transesterify palm oil to biodiesel in a reaction time of 30 min.…”

Calcined biowaste durian peel (BDP) contains 86% potassium element as the main compound and has successfully catalyzed the transesterification of palm oil to biodiesel at room temperature. The effect of catalyst weight, molar ratio of palm oil to methanol, reaction time, and rotational speed of the homogenizer device was investigated on biodiesel conversion and yield. The highest biodiesel conversion of 97.4 ± 0.3% was achieved using the following reaction conditions: a catalyst weight of 5 wt %, a molar ratio of palm oil to methanol of 1:15, a reaction time of 10 min, and a rotational speed of 6000 rpm. Unfortunately, calcined BDP could not hold its catalytic activity in the reusability study. The biodiesel conversion was decreased in the second cycle due to the decrease of both catalyst weight and concentration of potassium ions after the first cycle. However, the calcined BDP paired with a homogenizer device could produce biodiesel in a short reaction time and at room temperature.

This study investigates silver adsorption on biochar produced from pyrolysis of spent coffee grounds (SCGs). Biochars were produced from SCGs at temperatures between 500 and 1000 °C. SCG-derived biochars were then characterised by different analytical methods, such as Brunauer-Emmet-Teller (BET), Fourier transform infrared (FTIR), X-ray diffraction (XRD), and investigated for silver removal. The results revealed that the biochar produced at 500 °C offered a maximum surface area of 40.1 m2/g with a yield of 23.48% biochar and the highest silver adsorption capacity of 49.0 mg/g with 99.9% silver removal efficiency. The morphology of adsorbed silver on biochar was determined using scanning electron microscopy–energy-dispersive spectrometry (SEM–EDS), and XRD analyses, which showed an even distribution of silver on the biochar surface. Furthermore, X-ray photoelectron spectroscopy (XPS) confirmed that part of the silver ions was reduced to form metallic silver (Ag0)/silver nanoparticles (Ag NPs) during adsorption. The kinetics and isothermal evaluation suggested that silver adsorption was dominated by the pseudo-second-order model and Langmuir isotherm, which means that silver adsorption was mainly dominated by chemisorption and monolayer on biochar surface. Overall, this study suggests that 500 °C was the most feasible pyrolysis temperature to produce SCG-derived biochar with suitable physicochemical properties that can efficiently adsorb silver species from wastewater.
