“…Waste cooking oil is obtained from edible oils that have been used for frying food [ 62 ]. These types of food wastes are harmful to human health and to the environment when they are improperly disposed of by not submitting them to any treatment processes [ 63 ].

“…Waste cooking oil is seen as a promising feedstock for biodiesel production due to its low cost and abundance in several countries [ 64 ]. The employment of previously used cooking oils as raw materials does not create controversial issues, such as discussions about the clash between the food and fuel industries, or environmental reservations [ 63 ]. The use of this raw material for the production of biofuels was first reported a long time ago, and research on the topic started as early as the 1970s [ 65 ].…”

Biodiesel can be produced from vegetable oils, animal fats, frying oils, and from microorganism-synthesized oils. These sources render biodiesel an easily biodegradable fuel. The aim of this work was to perform an advanced bibliometric analysis of primary studies relating to biodiesel production worldwide by identifying the key countries and regions that have shown a strong engagement in this area, and by understanding the dynamics of their collaboration and research outputs. Additionally, an assessment of the main primary feedstocks employed in this research was carried out, along with an analysis of the current and future trends that are expected to define new paths and methodologies to be used in the manufacture of biodegradable and renewable fuels. A total of 4586 academic outputs were selected, including peer-reviewed research articles, conference papers, and literature reviews related to biodiesel production, in the time period spanning from 2010 to 2021. Articles that focused on feedstocks for the production of biodiesel were also included, with a search that returned 330 papers. Lastly, 60 articles relating to biodiesel production via sewage were specifically included to allow for an analysis of this source as a promising feedstock in the future of the biofuel market. Via the geocoding and the document analyses performed, we concluded that China, Malaysia, and India are the largest writers of articles in this area, revealing a great interest in biofuels in Asia. Additionally, it was noted that environmental concerns have caused authors to conduct research on feedstocks that can address the sustainability challenges in the production of biodiesel.

The object of this study is the process of operation of a diesel engine in a wheeled tractor on methyl ether of spent frying sunflower oil. The task being solved is to improve the environmental performance of a diesel engine in a wheeled tractor during the operation of its diesel on such biodiesel fuel and its mixtures with mineral diesel fuel. The characteristics of the diesel D-243 were determined by the experimental method with the measurement of the toxicity of the waste gases during its operation on the methyl ether of the spent sunflower oil, mineral fuel, and their mixtures. A decrease in the content of soot in diesel exhaust gases and a slight increase in the types of nitrogen oxides was registered. The theoretical method using a mathematical model determined the indicators of a wheeled tractor during its movement with a trailer for the accepted driving cycle and the operation of its diesel on different fuels. To that end, the characteristics of a specific diesel engine were described by polynomial models. The adequacy of the mathematical model of the movement of a tractor with a trailer over a driving cycle was tested. By means of a mathematical model, the total road emissions of harmful substances of a diesel engine were calculated when the tractor is running with a trailer over the accepted driving cycle. Calculations were performed for two types of fuel: mineral diesel fuel and biodiesel fuel. Biofuel consumption increases by almost 10 % compared to diesel fuel. The total emissions of harmful substances are 1.1 times lower in a diesel engine running on biofuel than when using mineral fuel. The results could be used in the operation of technological transport in the industry and agriculture provided there is a sufficient volume of raw materials for the production of biofuel

Natural cosmetic products have attracted significant attention due to their eco-friendliness compared to synthetic products. The development of more benign production methods for these products not only increases the functionality and stability but also aligns them with the principles of green chemistry and organic standards. One such method uses the vortex fluidic device (VFD), which is an efficient thin-film device that utilizes a rapidly rotating tube to implement high shear forces, overcoming the mixing and heat transfer limitations of traditional batch processing. Herein, the stability and cleansing functions of a predeveloped organic shampoo are improved by incorporating the VFD processing without clogging problems. Shampoo processed by VFD in a standard 20 mm diameter tube inclined at 45°and rotating at 4500 rpm showed the most decrease in particle size and an improvement in both viscosity and storage time. The processed shampoo remained unseparated even after 30 days under 50 °C heating. In addition, the foaming and cleansing function of the processed shampoo increased, making it easier to remove dirt from hair compared to the nonprocessed product. Overall, the VFD processing technology demonstrates a green, one-step technique for value-added natural cosmetic products such as organic shampoo.
