Bioenergy from biofuel residues and waste

Abstract

This article is a review of the scientific literature published in 2019 on topics relating to bioenergy from biofuel residues and waste. This literature review is divided into the following sections: Feedstocks, Biodiesel, Bioethanol, Hydrogen, Biohydrogen, Biofuel Residues, Microalgae, and Lignocelluloses.

Rhodotorula mucilaginosa—alternative sources of natural carotenoids, lipids, and enzymes for industrial use

“…Due to the non-renewability of fossil fuels and the ever-decreasing supply, researchers are focusing on investigating clean and renewable alternatives ( Abas et al., 2015 ). Bioenergy is quickly becoming one of the most important alternatives to traditional energy sources, helping to diversify the energy mix and lessen reliance on global oil markets, and is expected to replace conventional petroleum or diesel fuels ( Sheehan et al., 2020 ). The global bioenergy market is rapidly expanding.…”

“…Therefore, further research should focus on the economization of operating costs. This can be accomplished by using genetically modified techniques to improve microorganism biosynthesis efficiency or by utilizing waste as medium components ( Sheehan et al., 2020 ).…”
