“…Moreover, biodiesel is celebrated for its environmentally friendly attributes, as it significantly reduces greenhouse gas emissions and air pollutants when compared to traditional petroleum-based fuels [56]- [59]. Additionally, biodiesel is known for its low toxicity, making it a safer and less hazardous option for both human health and the environment [60], [61].…”

Biodiesel production has been an important part of a global effort to replace fossil fuels with renewable energy sources. However, one of the problems facing biodiesel production is increased production of glycerol as a by-product. Glycerol, or crude glycerol (CG), is generally produced in significant quantities and needs to be managed wisely. This article discusses the potential use of glycerol from biodiesel production as a raw material for bioethanol production. By optimizing fermentation processes, genetic engineering technology, and purification, glycerol can be converted into bioethanol, one of the more environmentally friendly renewable fuels. The success of the conversion of glycerol to bioethanol is also supported by advances in genetic engineering technology that enable the development of more efficient and productive microorganisms. This creates great opportunities to reduce waste, support resource sustainability, and reduce dependence on fossil fuels through the use of glycerol as a bioethanol raw material. Conversion of glycerol to bioethanol is a step towards more sustainable and environmentally friendly renewable energy.

“…Recent studies by Landwehr et al focus on the effects of exhaust aerosol produced from the combustion of different bio-based fuels in an engine [ 9 ]. When combusted, the exhaust of bio-based containing fuels, i.e., biodiesel was shown to be less toxic to human lung cells compared to the exhaust of fossil fuels [ 10 ]. Depending on the feedstock biodiesel is made from the toxicity to human lung cells varies [ 11 ].…”

Gaseous and semi-volatile organic compounds emitted by the transport sector contribute to air pollution and have adverse effects on human health. To reduce harmful effects to the environment as well as to humans, renewable and sustainable bio-hybrid fuels are explored and investigated in the cluster of excellence “The Fuel Science Center” at RWTH Aachen University. However, data on the effects of bio-hybrid fuels on human health is scarce, leaving a data gap regarding their hazard potential. To help close this data gap, this study investigates potential toxic effects of a Ketone-Ester-Alcohol-Alkane (KEAA) fuel blend on A549 human lung cells. Experiments were performed using a commercially available air-liquid interface exposure system which was optimized beforehand. Then, cells were exposed at the air-liquid interface to 50–2000 ppm C3.7 of gaseous KEAA for 1 h. After a 24 h recovery period in the incubator, cells treated with 500 ppm C3.7 KEAA showed significant lower metabolic activity and cells treated with 50, 250, 500 and 1000 ppm C3.7 KEAA showed significant higher cytotoxicity compared to controls. Our data support the international occupational exposure limits of the single KEAA constituents. This finding applies only to the exposure scenario tested in this study and is difficult to extrapolate to the complex in vivo situation.
