“…326 Kamaronzaman et al reported a strong base catalyst derived from eggshells with modification by doping nickel. The catalyst was prepared by calcined at 1000 °C for 4 h. The biodiesel yield reached 100% from waste cooking oil with a time of 2 h. 327 Putra et al presented a CaO/SiO 2 catalyst isolated from cheap and abundant wastes of eggshells and peat clay. The waste shells were calcined at 700 °C for 4 h to get the desired catalyst.…”

“…Meanwhile, if the catalyst concentration is too low, biodiesel production also decreases because excess unreacted methanol will react with glycerol and limit the biodiesel yield. Moreover, low catalyst concentration indicates that lower catalytic sites are available for the catalyzed transesterification process 98, 145, 146.…”

The increasing demand of the world energy consumption has made it necessary to shift energy technologies toward renewable energy sources. The sustainability of feedstock can be maintained when utilizing feedstock from waste sources, such as dairy waste, food waste, and others. Dairy waste is one of the cheapest sources available. The compositions of dairy waste scum, including free fatty acids (8–10 %), triglycerides (more than 80 % in dry bases), and fats around 60 %, which have the potential to be used as the feedstock for biodiesel production in the presence of certain catalysts. To ensure more sustainability, the catalyst should be derived from waste (e.g., eggshells and cow bones) that consists of calcium oxide, which can then be used to catalyze the transesterification of dairy waste. This review emphasizes the current production of dairy waste globally and the potential of the waste and other types of organic waste as feedstock for biodiesel production, as well as determines the optimum reaction conditions for high‐quality biodiesel production.

“…The method of preparation of eggshell powder is shown in Figure 1. The collected eggshell was first washed in water and later boiled in a distilled water for 1 h to remove all the impurities [31]. It was dried in a sunlight then kept in an oven for overnight at a temperature of 110 • C. Initially, normal grinder was used to make eggshell powder; later, planetary ball mill machine was used to make fine calcium oxide (CaO) powder as shown in Figure 2.…”

Transesterification of Pyrolysed Castor Seed Oil in the Presence of CaCu(OCH3)2 Catalyst

et al. 2021

Energy consumption is on the rise due to rapid technological progress and a higher standard of living. The use of alternative energy resources is essential to meet the rising energy demand and mitigate the carbon emissions caused due to use of fossil-based fuels. Biodiesel produced from non-edible oils such as castor seed oil (CO) can be used in diesel engines to replace fossil diesel. However, the quality and yields for CO biodiesel is low due to the presence of ricinolic acid C18:1OH (79%). In this study, two-stage conversion techniques were used to improve the yields and properties of CO biodiesel. The catalyst CaCu(OCH3)2 was prepared from waste eggshell and synthesized with copper oxide in the presence of methanol. The castor oil was subjected to pyrolysis at 450–500 ℃ and then transesterified in the presence of modified catalyst. The reaction parameters such as methanol-to-oil ratio and catalyst and reaction time were investigated, and the optimum combination was used to produce castor biodiesel from pyrolysis castor oil. Results showed that the cetane number and oxidation stability were increased by 7% and 42% respectively. The viscosity, density, flash point, and iodine value were decreased by 52%, 3%, 5% and 6%, respectively. The calorific values remained the same. This study suggests that pyrolyzed castor seed oil followed by transesterification in the presence of a modified catalyst gave better fuel properties and yields than the conventional transesterification process for biodiesel fuel production.
