Microbial surfactants are amphiphilic surface-active substances aid to reduce surface and interfacial tensions by accumulating between two fluid phases. They can be generically classified as low or high molecular weight biosurfactants based on their molecular weight, whilst overall chemical makeup determines whether they are neutral or anionic molecules. They demonstrate a variety of fundamental characteristics, including the lowering of surface tension, emulsification, adsorption, micelle formation, etc. Microbial genera like Bacillus spp., Pseudomonas spp., Candida spp., and Pseudozyma spp. are studied extensively for their production. The type of biosurfactant produced is reliant on the substrate utilized and the pathway pursued by the generating microorganisms. Some advantages of biosurfactants over synthetic surfactants comprise biodegradability, low toxicity, bioavailability, specificity of action, structural diversity, and effectiveness in harsh environments. Biosurfactants are physiologically crucial molecules for producing microorganisms which help the cells to grasp substrates in adverse conditions and also have antimicrobial, anti-adhesive, and antioxidant properties. Biosurfactants are in high demand as a potential product in industries like petroleum, cosmetics, detergents, agriculture, medicine, and food due to their beneficial properties. Biosurfactants are the significant natural biodegradable substances employed to replace the chemical surfactants on a global scale in order to make a cleaner and more sustainable environment.

“…Due to its outstanding adhesive characteristics, the surfactant of amino acid is an ideal softening agent and lubricant in textiles [74,75]. Biosurfactants are accepted in the replacement of petroleumbased surfactants due to their sustainability, biodegradability, less effluent load, being economically viable, and cheaper starting material (the leather waste in this case) [76]. As a result, an amino acid-based surfactant can be the potential replacement for petroleum-based surfactants for textile applications.…”

The use of biomass to produce bioenergy and biomaterials is considered a sustainable alternative to depleting fossil fuel resources. The world tanneries consume 8–9 MT of skin and hide every year producing 1.4 MT of solid waste. Most of the solid biomass generated from tanneries is disposed of as waste in the environment using either landfilling or thermal incineration. Disposal of this waste into the environment affects the ecosystem, causing bad odor (air pollution) and has an antagonistic impact on the environment. Due to this, European Union legislation bans the landfilling of biomass. This study aims to comprehensively review the possible valorization routes of leather processing industry biomass into high-value biomaterials. Leather biomass (trimmings, shaving, splitting, and buffing dust) mainly contain 30%–35% collagen protein, which is produced by acid or alkali hydrolysis. The biopolymers obtained from leather industry biomass can be utilized in the production of several high-value materials. In addition, leather processing industry biomass also contains fat, which can be converted into a bio-surfactant, and other useful biomaterials. Keratin protein can also be extracted from the hair waste of hides and skins. The increased demand for biomaterials makes the using of leather industry biomass very attractive. From this study, it can be concluded that the conversions of leather processing industry waste to valuable biomaterial can protect the environment, generate additional income for leather industries, and pave way for sustainable and renewable biomaterials production.

“…The use of eco-friendly biosurfactants is an alternate approach for lowering environmental impact. Studies on the application of biosurfactants in scouring are limited, mainly consisting of the plant-based biosurfactant saponin from Quillaja Saponara, and oat extract [38,39].…”

Sustainable Routes for Wool Grease Removal Using Green Solvent Cyclopentyl Methyl Ether in Solvent Extraction and Biosurfactant Wool Protein Hydrolyzate in Scouring

This work focuses on introducing new sustainable chemicals in the wool grease removal processes by aiming to understand the effect of an eco-friendly solvent, cyclopentyl methyl ether (CPME), in solvent-based wool grease extraction and, in addition, the impact of the wool protein hydrolyzate (WPH) as a biosurfactant derived from green hydrolysis in the wool scouring process. In the green solvent extraction process assisted using solvent CPME, the effect of CPME on grease extraction and the presence of four primary fatty acids were evaluated and compared with conventional solvents. The quantity of grease extracted using green solvent CPME was more significant than the conventional solvents. An extraction using green solvent CPME resulted in 11.95% extracted wool grease, which is more when compared with 8.19% hexane and 10.28% diethyl ether. The total quantity of four fatty acids was analyzed and found to be ~15% for CPME ~17% for Hexan compared with ~20% for commercial lanolin. FTIR of CPME-extracted wool grease exhibits primary and distinguishing bands similar to pure wool grease. Wool cleanliness efficiency was morphologically analyzed using SEM, resulting in no fiber degradation or surface alterations. These analyzes indicated that CPME has the potential to be claimed as an effective green alternative to conventional solvents for the extraction of grease and fatty acids. In a sustainable scouring process, WPH was used as a biosurfactant, an eco-friendly alternative. Furthermore, scouring process parameters such as temperature, material-to-liquor ratio, and WPH concentration were optimized for efficient scouring. The wool samples scoured using WPH biosurfactant exhibited nearly similar whiteness and yellowness and washing yield compared with Biotex AL. These results comply with SEM analysis, which showed that WPH-scoured wool had an intact scale structure, a smooth fiber surface, and no wool grease layer. At optimum conditions, WPH reduced the residual grease content of Sopravissana wool from 22.29% to 0.30%, comparable to the commercial biosurfactant Biotex AL. Compared with conventional wool grease removal processes, the green solvent CPME and biosurfactant WPH were considered viable, sustainable, and environmentally friendly alternatives.
