“…Other anhydrosugar alcohols such as 1,4‐anhydroxylitol, 1,4‐anhydroerythritol, and levoglucosan have the potential to be used as a polar moiety to synthesize tensoactive species (Galletti et al, 2007; Itabaiana Junior et al, 2020; Regeling et al, 1993). Levoglucosan is worth mentioning as an example of the upcycling of lignocellulosic biomass and derivatives.…”

This work reviews the use of carbohydrates and their derivatives as renewable raw materials in the production of surfactants. Methods to attain state‐of‐the‐art carbohydrate‐derived surfactants are described. This includes surfactants widely used nowadays and others that have not yet transcended beyond the academic field. Given the abundance of hydroxyl groups in carbohydrates and the considerable quantity of different surfactant structures that can be generated during their synthesis, selectively obtaining a target product represents a challenge. Therefore, this work focuses on the platform chemicals available to synthesize biobased surfactants. The first part of the review comprises a brief introduction of simple and complex carbohydrates to better understand their chemistry. Then, a description of the processes to obtain biobased building blocks derived from carbohydrates according to the National Renewable Energy Laboratory (NREL, USA), and their usefulness in synthesizing surfactants is presented. This provides an organized inventory of the knowledge around the synthesis–production of surfactants from carbohydrate derivatives, emphasizing raw materials that could be inserted into the circular bioeconomy concept. Finally, the current industry trends and the potential role of biobased surfactants around new dioxane regulations are discussed.

“…Nowadays, looking for alternative renewable bio-resources is urgent and important in order to replace non-bio and non-renewable ones conventionally employed in different industrial areas. The valorization of biomass, currently experiencing a great blooming, constitutes a considerable pathway among the available and proposed solutions [1][2][3]. Moreover, the intensive exploitation of fossil sources is one of the major causes of the CO 2 emissions, a hazardous greenhouse gas and a major cause of the global warming that is dangerously threatening our existence [4].…”

The high life expectancy of the world population provokes increase in demand for food and energy. As a result, the intense industrialization and the application of fossil sources is responsible for high levels of CO2 emission and waste generation. To mitigate the CO2 emission a practical solution at the very short term is urgently needed. The capture of CO2 and its application in chemical processes for the valorization of residual biomass are of great importance nowadays. The application of CO2 in the selective carboxylation of furoic acid for the production of 2,5-furandicarboxylic acid (FDCA), a bio-based monomer, has been an important step towards obtaining biopolymers to replace petroleum-based plastics such as polyethylene terephthalate (PET). In this project report, we discuss on the current challenges for obtaining the 2,5-FDCA precursor from the furfural in two main routes involving oxidation and carboxylation via heterogeneous catalysis. We present the main objectives and discuss the importance of this research for the development of more sustainable processes.

“…This fact is often overlooked, as most of this biomass is used non-commercially for energy and heating, which is inefficient in terms of productivity, in addition to generating more pollution. Due to its chemical and structural complexity, biomass can be used in a better way through the synthesis of bio-based fuels or value-added chemicals [ 9 , 10 ].…”

As a consequence of intense industrialization in the last few decades, the amount of agro-industrial wastes has increasing, where new forms of valorization are crucial. In this work, five residual biomasses from Maranhão (Brazil) were investigated as supports for immobilization of lipase from Thermomyces lanuginosus (TLL). The new biocatalysts BM-TLL (babaçu mesocarp) and RH-TLL (rice husk) showed immobilization efficiencies >98% and hydrolytic activities of 5.331 U g−1 and 4.608 U g−1, respectively, against 142 U g−1 by Lipozyme® TL IM. High esterification activities were also found, with 141.4 U g−1 and 396.4 U g−1 from BM-TLL and RH-TLL, respectively, against 113.5 U g−1 by TL IM. Results of porosimetry, SEM, and BET demonstrated BM and RH supports are mesoporous materials with large hydrophobic area, allowing a mixture of hydrophobic adsorption and confinement, resulting in hyperactivation of TLL. These biocatalysts were applied in the production of hexyl laurate, where RH-TLL was able to generate 94% conversion in 4 h. Desorption with Triton X-100 and NaCl confirmed that new biocatalysts were more efficient with 5 times less protein than commercial TL IM. All results demonstrated that residual biomass was able to produce robust and stable biocatalysts containing immobilized TLL with better results than commercial preparations.
