“…These residual biomasses are, therefore, called pectin-rich biomasses. In them, the lignin content hardly exceeds 2% of the dry weight, which makes their pretreatment (the process prior to hydrolysis and fermentation) more economical than that of lignocellulosic biomasses, where the percentage of lignin can exceed 30% (Venkatanagaraju et al, 2020;Paliga et al, 2022).…”

“…Polygalacturonate lyase catalyzes the cleavage of ß-1,4 bonds in an endo or exo manner by trans elimination. The total hydrolysis of pectin releases especially the monosaccharides D-galacturonic acid, D-galactose, L-rhamnose, L-arabinose, and D-xylose (Satapathy et al, 2020;Bassim Atta and Ruiz-Larrea, 2022;Paliga et al, 2022).…”

“…A profitable and environmentally sustainable destination for the residual orange biomass is the production of second-generation ethanol (2G ethanol). This residual plant biomass is rich in pectin, a heteropolysaccharide that, when hydrolyzed, mainly releases the sugars galacturonic acid, galactose, rhamnose, arabinose, and xylose (Paliga et al, 2022). Therefore, ethanol production from this substrate depends on the action of microorganisms capable of metabolizing the aforementioned carbohydrates via fermentation.…”

It is mandatory to make the circular economy a reality, developing ways of transforming waste into valuable products. In this context, investigating the biotechnological potential of different residues is most welcome. This review analyzes how orange waste can be used as biorefinery feedstock to produce different bioproducts using yeasts as the major biocatalysts. In addition to the current orange market, its pectin-rich biomass is described in detail, aiming to elucidate how yeast cells can convert it into ethanol, xylitol, polyphenols, and organic acids (some of them, volatile compounds). Genetic, metabolic, and evolutionary engineering are also analyzed as biotechnological tools to improve the existing processes. Finally, this review also addresses the potential employment of fruit-dwelling yeasts in biorefining pectin-rich biomasses such as orange wastes. All the data presented herein lead to the conclusion that these residues could already be used for noble purposes.

As the world grapples with the challenges of climate change and the depletion of fossil fuel reserves, the transition towards sustainable transportation has become imperative. Various alternative energy options to enhance sustainable transportation such as solar, wind, hydroelectric, biofuels, and hydrogen, highlighting their potential to mitigate greenhouse gas emissions needs to be explored. Real-world cases drawn from various international contexts were examined to offer important insights into how sustainable mobility practices may be supported by alternative energy solutions. Some challenges in transitioning to sustainable transport systems which include energy efficiency, scalability, infrastructure needs, and environmental impact were identified. This introduction explores the potential of alternative energy sources in enhancing sustainable transportation, focusing on their advantages, challenges, and transformative impact on promoting greener, more equitable, and efficient mobility solutions. The remainder of the chapter is described as follows: Section 2 presents the electric vehicles (EVs) applications. Section 3 reviews hydrogen fuel technology. Section 4 examines the biofuels energy. Section 5 presents the environmental impacts and benefits of alternative energy sources. Section 6 explains ways of overcoming challenges and adoption while Section 7 finally concludes the chapter by discussing case studies and best practices on alternative energy sources.
