“…Because of its heterogeneous and non-leachable nature, the catalyst derived from tucumã peels could be reused at least 5 times. In another study, an ash catalyst from Tectona grandis leaves was developed and utilized for the transformation of WCO to FAME by Gohain et al 285 The measured surface area and pore size of the catalyst were 116.833 m 2 g À1 and 112.210Å, respectively, as calculated from BET data. 100% oil transformation to FAME was accomplished at room temperature using the optimized reaction conditions.…”

“…The magnetic hot plate was used as a source of heat and agitation to enhance a uniform temperature and proper mixing of the reactants. The temperature of the reaction was kept constant at 65 °C and at a stirring speed of 800 rpm 16,27,28 . Reaction was carried out at different runs depending on the parametric conditions according to the design matrix generated by BBD as shown in Table 2.…”

Biological waste materials are rich sources of important minerals such as calcium and potassium, which are required in the preparation of effective biocatalysts for biodiesel production. Their adoption into green catalyst production is becoming important due to the ease of process synthesis and the availability of waste animal shells and agricultural materials. In this study, the potential of a bi‐component, heterogeneous catalyst of fused chicken eggshells and pawpaw peels was tested in the transesterification reaction of linseed oil. The waste materials, separately, were dried and calcined at 900 °C or at 700 °C for 3 h to obtain their calcined ashes (calcined eggshells (CES) and calcined pawpaw peels (CPP)). The CES and CPP were then bonded by the wet impregnation method (by dissolving each ash at weight concentration of 7:3 CES/CPP in 100 mL warm distilled water and further calcining them at 600 °C for 2 h). The catalyst that was developed was characterized using Scanning Electron Microscopy ‐ Energy Dispersive X‐Ray Spectroscopy (SEM–EDX), X‐ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The Box–Behnken design was applied to generate 15 experimental runs, which were used to investigate the effect of the operational parameters such as methanol‐to‐oil molar ratio, catalyst loading, and reaction time. The characterization results show that the ash is very rich in Ca and K ions. The best reaction condition for the transesterification process was found to be a methanol / oil molar ratio of 14.9:1, catalyst loading of 3.78 wt%, process reaction time of 80 min at constant reaction temperature of 65 °C with a biodiesel maximum yield of 91.20 wt%. The physicochemical properties of the produced biodiesel were measured and found to meet the American Society for Testing of Materials (ASTM) and European National (EN) standards and South African National Standards (SANS) biodiesel quality standards. The fused catalyst can be reused for up to five cycles with little reduction in yields. The study demonstrates the potential of utilizing biomass feedstock in developing effective and sustainable biodiesel fuels. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Recently, the researcher demonstrated the dual role of agro‐waste based catalytic systems in terms of catalyst as well as solvent media have attracted huge attention to organic chemists for the synthesis being an excellent alternative tool . Several agro‐waste derived catalytic systems such as WEPBA, WERSA, WEB, BFE, Onion peel, Water hyacinth and WELFSA have been employed efficiently for various organic transformations.Very recently, researchers have also employed CTGL, CCPS, CBPA as the efficient heterogeneous catalyst for Knoevenagel condensation. Thus, all these findings inspired us to achieve an efficient approach for the synthesis of pyran derivatives catalyzed by WEMFSA at room temperature.…”

An eco‐friendly and facile three‐component reaction for the synthesis of 2‐amino‐4H‐pyran and tetrahydrobenzo[b]pyran derivatives is established using agro‐waste based Water Extract of Muskmelon Fruit Shell Ash (WEMFSA) as a catalyst. The present method offers several advantages such as efficient, mild reaction condition, simple product isolation and economic approach at room temperature in the absence of an external base or ligand/catalyst/additives. Thus, this approach is a very good alternative to existing protocols, because of non‐hazardous catalyst and mild condition use. Muskmelon fruit dried shells underwent thermal treatment followed by deionised water soak gave WEMFSA catalytic media. It is notable that, this method is found to be clean and high yielding target product isolation using simple filtration after reaction mixture dilution with water and analytical pure form was obtained after recrystallization with absolute ethanol. The synthesized products are characterized using various spectroscopic methods such as FT‐IR, 1H‐, 13C‐NMR and mass spectrometry techniques.
