“…The spectral peak of the functional group that corresponds compounds can be a good indication that the produced product is possessing components of biodiesel (Shalaby and El-gendy 2012; Meena Devi et al 2015;Mabayo et al 2018). Therefore, FTIR spectrometry is done to determine the group of compounds present in biodiesel.…”

In this study, the waste oil of rendered pork (WO-RP) from a food processing industry was studied as a source of biodiesel. The WO-RP was characterized and was found to have a high acid value of 4.30 mg KOH/g. A pre-treatment using H 2 SO 4 was done through the standard titration method that resulted in a reduction of acid value to 0.75 mg KOH/g. The transesterification process over the KOH catalyst was carried out and optimized using the central composite design (CCD) using the Design Expert 7.0 software. The optimum conditions were found at 3:1 methanol-oil molar ratio, 0.55% catalyst loading, and 45-min reaction time. At optimum conditions, the biodiesel yield was 95.28 ± 0.15%. Its chemical characteristics were tested in terms of acid value at 0.75 mg KOH/g, ash content at 0.01 wt%, density at 0.86 g/cm 3 , HHV at 39.98 MJ/kg, water content at 0.10%, and kinematic viscosity at 6.9 mm 2 /s. The FAME profile shows the presence of linoleic, palmitic, oleic and stearic acid as major fatty acid components and functional group shows carbonyl group with traces of carboxylic at 1719 cm −1 and the sharp peak of esters at 1749 cm −1 indicating that the derived product is biodiesel. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

“…En el espectro del biodiésel, esta banda disminuye pero no desaparece, lo que indica bajo contenido de residuos de metanol o humedad [54]. En los dos espectros, las bandas entre 2800 y 3000 cm -1 señalan la presencia de enlaces simétricos y asimétricos C-H. Los picos a 2916 cm -1 en las grasas y a 2922 cm -1 en el biodiésel corresponden a vibraciones de estiramiento de los grupos metilo, mientras que el pico a 3007 cm -1 se atribuye al estiramiento -HC=CH-del éster metílico, característico de los compuestos insaturados [55][56][57][58][59]. Los picos entre 1462 y 1400 cm -1 en el espectro de las grasas y a 1458 y 1435 cm -1 en el del biodiésel se atribuyen al estiramiento asimétrico del enlace -C-H y a las flexiones asimétricas del grupo funcional.…”

La búsqueda de materias primas no alimenticias es uno de los principales retos en la producción de biocombustibles. Para biodiésel, las investigaciones se orientan hacia el uso de cultivosno convencionales, así como hacia residuos o desechos con alto contenido de grasas y aceites. Laborra de café contiene una buena proporción de grasas y es un residuo comercial y doméstico. Eneste trabajo, se evaluó la producción de biodiésel utilizando las grasas extraídas de la borra del cafémediante un proceso en dos etapas. Las grasas extraídas de la borra de café con ebullición a reﬂujocon hexano como solvente presentaron una elevada acidez, 32,07 ± 0,01% (70,24 ± 0,03 mg KOH/ggrasa), lo que indica un alto contenido de ácidos grasos libres (AGL). Primero, las grasas se esterifcaron a 60ºC y 100 rpm, variando las condiciones de reacción. A las mejores condiciones, concentraciónde H2SO4 al 0,7%, RMG:MeOH de 1:6 durante 120 min, la acidez disminuyó por debajo del 1%, conel 94,92% de conversión AGL a ésteres metílicos. Se sometieron a un proceso de transesterifcacióncon KOH (1,5% m/v) en presencia de metanol (RMG:MeOH de 1:15) a 60ºC y 100 rpm durante 30 min.El biodiésel se separó por decantación y se purifcó mediante lavados sucesivos con agua acidulada,que resultó ser una mezcla de ésteres metílicos de los ácidos linoleico (48,40%), palmítico (36,21%),esteárico (8,69%) y oleico (6,69%), cuyas propiedades se ajustan a los requerimientos de las normasASTM D 6751 y EN 14214 .

“…There is a pressing need to look for alternate renewable energy sources. Alternative fuels should be technically feasible, cost‐effective, environmentally friendly, and readily available (Hadidchi et al, 2020; Meena Devi et al, 2015). Fatty acid methyl esters (FAMEs), which are produced from sustainable oil sources such as vegetable oils.…”

Biodiesel is a sustainable, inexpensive, and alternative energy source produced from vegetable oils and animal fats. Precise and authentic identification of oil yielding plant species is very crucial. Therefore, scanning electron microscopy (SEM) was employed in our current investigation to study micromorphological characteristics of ten novel oil yielding seeds for their reliable identification. Macromorphological characters of sample seeds were explored by light microscopy. Seed size varied from 16 to 6.2 mm in length and 18.4–4.5 mm in width. Seed shape varied from ovoid to cordial and color from beige to brown. Seed oil content ranged from 25% to 45% (w/w). Whereas free fatty acid (FFA) content of seed oil varied from 0.42 to 3.4 mg KOH/g. Biodiesel potential of Chamaerops humilis was found to be highest (98%) in all. Besides, ultra‐structural observation of seeds demonstrated variation in surface sculpturing which varied from rugous, reticulate, perforate, striate, and webby. Periclinal wall arrangements varied from rough, ridged, depressed, thick and curved whereas, anticlinal walls pattern showed variation from wavy, smooth, raised, deep and depressed. It was ultimately concluded that Scanning electron microscopy could serve as an advanced tool representing hidden ultra‐structural characters of seeds. It offers significant knowledge to researchers and local community for their accurate and genuine identification. Research Highlights Non‐edible oil yielding seeds as promising source of bioenergy. Scanning electron microscopy (SEM) as reliable tool for identification. Variation in Micromorphological characters among selected seeds. Classification of non‐edible oil yielding plants via micromorphological characters.
