“…Similarly in another work by our group on WCO, sonochemical reactors were employed for biodiesel generation by transesterification reaction of frying oil using a homogenous catalyst (KOH). It can be concluded that cavitation phenomenon enabled to create an effective environment to accelerate mass transfer in the reaction so that the rate of transesterification significantly enhanced …”

With the progress in technology and population, an enormous amount of agricultural and food waste is being generated throughout the world. In the past, food and agro‐wastes were either burnt off or allowed to rot in fields, but this can be potentially hazardous to the environment. Therefore, approaches with respect to their utilization, reuse, and processing need to be developed to enable the sustainable utilization of feedstock and reduce pollution. Agricultural wastes mainly comprise of cellulosic fibres possessing high fixed carbon content and multifunctional groups. Agricultural waste shows considerable applicability due to its high strength, environmentally benign nature, low cost, and ease of availability and reusability. All these characteristics have been researched upon in the past, in the sector of waste water management for the removal of heavy metals and dyes. Similarly, a variety of food and agro‐waste has been adopted as sources for new drug leads or important phytochemicals with different therapeutic benefits. Agro‐waste can also be employed for enzyme immobilization after proper modification. Apart from this waste cooking oil comes under the category of food waste and can be processed to prepare alternate energy source such as biodiesel. This personal account summarizes the development, processing, and application of food and agro‐waste in the production of biodiesel, environmental remediation, curative medicine, and in the development of biocatalysts, by researchers in our laboratory.

“…Their results showed that methanol to oil molar ratio was the one of the considerations for high methyl ester production. The methanol to oil ratios; 3:1, 4.5:1 and 6:1 delivered the methyl ester value 54, 93.86 and 95.4 wt% respectively [46] . The independent parameters for the diameter and depth of the hole were also one of the most considerations for the production of high methyl ester because the cavitation conditions and efficiency are directly related to the operating parameters and the geometries of the cavitation devices (eg.…”

Highlights Hydrosonic and ultrasonic reactors were compared in two-step biodiesel process. Key part is utilizing the 3D-printed rotor–stator. Methyl ester 99.163 wt% was produced using rotor–stator hydrodynamic reactor. Maximum yields 97.51 vol% purified biodiesel was achieved using HC reactor. The total average energy consumption of using HC reactor was 0.049 kW h/L.

“…Biofuels synthesized from biomass, especially biodiesel, offer a promising alternative substitute for petroleum-based fuels. Biodiesel has been considered as a potential fuel to reduce the green house effects, since it is environmentally friendly due to characteristic such as being biodegradable, non-toxic, renewable and for emitting less CO2, CO and sulfur [1,2,5]. Despite all these advantages, biodiesel does not compete economically with diesel derived from fossil fuels due to its high production cost [4].…”

“…Biodiesel can be obtained from vegetable oil, animal fat and non-edible plant oil, however, vegetable oils are the most common source, leading to an intense debate between the use of such oils for food or for fuel, since vegetable oils are very important for animal and human food purposes, and their utilization for biodiesel synthesis is not yet viable due to its high production cost [4,6]. Different technological solutions have been proposed to increase the use of other sources of oil, such as waste cooking oil, to reduce biodiesel production cost, since frying oil is much less expensive than pure vegetable oil [4,5].…”

Biodiesel stands out as a renewable, biodegradable, and non-toxic fuel when compared to fossil fuels, and has attracted significant attention from researchers and industries for environmental protection and sustainable development. However, around 95% of the world biodiesel production is derived from edible oils, which leads to a competition between oil production for food or for fuel and results in increased costs compared to diesel fuel. Biodiesel production from WCO offers a clean technological solution for both disposal of WCO and cost production problems. For these reasons, non-edible waste cooking oils are considered one of the most promising alternatives of raw material for biodiesel production. WCO can also promote social inclusion in urban areas by generating extra revenue by recycling. The aim of the present work was to develop a low-cost biodiesel reactor by Biosystems Engineering students and teachers from the School of Sciences and Engineering of São Paulo State University (UNESP). The primary goal was to include biofuels technology into the Biosystems Engineering undergraduate curriculum in order to integrate and transcend the contents contemplated in our course by helping the students to build a technological low-cost reactor with innovative research in the biofuels technology field.
