“…It was observed that biodiesel yield of sulfonated carbon catalyst was 90% via a two‐step reaction. Calcium (Ca)‐based catalysts have been used widely in the transesterification reaction because of their relatively high catalytic activity (El‐Gendy, Deriase, Hamdy, & Abdallah, ; Feyzi & Shahbazi, ; Shan, Zhao, Lv, Yuan, & Yao, ). The Ca‐based catalysts can be simply prepared from a large variety of feedstocks (calcium‐rich waste materials) via high‐temperature calcination, which are cost‐effective and environmentally friendly.…”

“…El‐Gendy et al. () investigated the production of biodiesel from sunflower WCO using a heterogeneous biocatalyst produced from eggshell and obtained a yield of 97.5% using methanol‐to‐oil ratio of 6:1 and a catalyst concentration of 3% at 60°C in 30 min. Omar and Amin () investigated alkaline‐modified zirconia (i.e., magnesium zirconium dioxide [Mg/ZrO 2 ], calcium zirconium dioxide [Ca/ZrO 2 ], strontium zirconium dioxide [Sr/ZrO 2 ], and barium zirconium dioxide [Ba/ZrO 2 ]) as the heterogeneous catalysts in biodiesel production from WCO.…”

The depletion of fossil fuel reserves and increasing demands for diesel are considered to be important triggers for many of the initiatives that have been taken to search for possible sources for the production of biodiesel from materials available within the country. It is possible to produce biodiesel from waste/used cooking oils (WCO) that is comparable in quality to that of fresh vegetable oil. Not only does reuse of WCO, which can otherwise harm human health, reduce the burden on the government of treating oily wastewater, disposing of the waste, and maintaining public sewers, it also significantly lowers the production cost of biodiesel. In the process of frying, oil undergoes many reactions, leading to the formation of a number of undesirable compounds, such as polymers, free fatty acids, and many other chemicals. This poses challenges in the transesterification of WCO. This article covers different techniques in the production of biodiesel from WCO.It also compares combustion, emissions, and engine performance characteristics of biodiesel from WCO as well as factors affecting biodiesel production from WCO and its economic feasibility.

“…Kulkarni and Dalai [20] reviewed methods of biodiesel production from WCO and discussed quality and performance of methyl esters derived from WCO. Few other researchers also investigated the utilization of WCO as biodiesel feedstocks [19,[21][22][23][24].…”

“…Also, it is difficult to recover the homogeneous catalyst and may corrode the pipelines and reactors. Alternatively, heterogeneous basic catalysts have shown several merits such as non-toxic, low-cost, and eco-friendly nature [24,28]. Furthermore, it can be reused, recycled and the product (biodiesel) needs less or no water wash and also produces by-product (glycerol) with high purity [5,19].…”

“…Response surface methodology (RSM) is a statistical approach to optimize the complex processes which helps to understand the interaction between the process parameters and also minimizes the number of experimental runs essential to obtain maximum conversion and also to acquire adequate data to prove that the result is statistically significant [36][37][38][39]. Several authors optimized biodiesel production using RSM techniques [24,[40][41][42][43].…”

In the present work, the waste material Donax deltoides shells (DDS) was utilized as a heterogeneous base catalyst for biodiesel production from Calophyllum inophyllum oil (CIO)-waste cooking oil (WCO) mixture. Non-edible CIO possessing 65 mg of KOH g − 1 of acid value was mixed with WCO of low acid value in different proportions. The acid value was reduced to 33.3 mg of KOH g − 1 of oil by using a volumetric ratio of 1:1 and it was further reduced to 5.6 mg of KOH g − 1 of oil by acid catalyzed esterification process and used for biodiesel production. DDS was converted into active CaO catalyst by calcination and the catalyst characterization was performed using different instrumental techniques. The impact of calcined DDS (catalyst) concentration, reaction time and methanol to esterified oil volumetric ratio on biodiesel conversion was investigated to optimize the transesterification reaction using response surface methodology based central composite design. The biodiesel conversion was determined by proton nuclear magnetic resonance spectroscopy and a maximum biodiesel conversion of 96.5% was achieved with catalyst concentration of 7.5 wt%, methanol to oil volumetric ratio of 63.8%, reaction time of 129.3 min, stirrer speed of 450 rpm and reaction temperature of 65°C.
