Abstract Liquid biofuels like biodiesel and bioethanol are crucial in the transition to low-carbon high-energy alternatives fossil fuels. One significant by-product of production is glycerol, which accounts for about 10% total conversion output. While waste glycerol poses challenges due its impurities contaminants, it also holds potential as a metabolic resource essential cellular components microorganisms. Crude reviewed, highlighting relevance current technologies biochemical composition. To efficiently utilize co-valorization with low-cost substrates through biocircular platforms using various microorganisms or insects second third-generation oxy-biofuels has been explored. Among these, black soldier fly larvae have demonstrated higher competitiveness lipid contents (35–43%), making them promising organism recycling into production, alongside microalgae oleaginous yeast. The microbial productivity from yeast notably (3546 kg ha −1 y ) than soybean (562 ), while microalgal surpasses palm by more 25 times. Remarkably, was reported be ~ 1.7 times an impressive 43 biodiesel. Despite their industry still represents challenge because high impurities, viscosity, limited direct applications existing processes. further enhance energy sustainability address discussed utilization domestic wastewater sludge, lignocellulosic biomass, protein-rich wastes. These offer opportunities create other sustainable agricultural products minimizing environmental footprint.

Abstract Background The main challenge for large-scale production of bacterial cellulose (BC) includes high costs interlinked with raw materials, and low rates. valorization renewable nutrient sources could improve the economic effectiveness BC fermentation while their direct bioconversion into sustainable biopolymers addresses environmental pollution and/or resource depletion challenges. Herein a green bioprocess was developed to produce in amounts rather unexplored strain Komagataeibacter rhaeticus, using waste streams such as wine distillery effluents (WDE) biodiesel-derived glycerol. Also, evaluated bio-adsorbent phenolics, dyes metals removal enlarge its market diversification. Results significantly affected by WDE mixing ratio (0–100%), glycerol concentration (20–45 g/L), type media-sterilization method. A maximum 9.0 g/L, productivity 0.90 g/L/day water holding capacity 60.1 g water/g dry BC, achieved at 100% ≈30 g/L crude samples showed typical vibration bands average fiber diameters between 37.2 89.6 nm. dephenolize adsorb phenolics during reached respectively, up 50.7% 26.96 mg gallic acid equivalents/g ( in-situ process). produced also investigated dye metal removal. highest yellow 17 (54.3%) recorded when 5% applied bio-adsorbent. Experiments performed multi-metal synthetic wastewater that remove 96% Zn 97% Cd. Conclusions This work demonstrated low-carbon approach low-cost, biodegradable BC-based bio-adsorbents, without any chemical modification. Their potential wastewater-treatment-applications highlighted, promoting closed-loop systems within circular economy era. study may serve an orientation future research towards competitive or targeted adsorption technologies treatment resources recovery.

Mechanochemistry and oleochemistry their combination have been known for centuries. Nevertheless, bioeconomy circular economy concepts is much more recent has motivated a regain of interest dedicated research to improve alternative technologies the valorization biomass feedstocks. Accordingly, this review paper aims essentially at outlining breakthroughs obtained in field mechanochemistry oleochemicals such as triglycerides, fatty acids, glycerol derivatives. The discusses advances production small chemicals derived from oils with brief overview vegetable oils, use synthesis biodiesel, lipidyl-cyclodextrine, dimeric labelled calcium diglyceroxide, acylglycerols, benzoxazine solketal. also briefly overviews limits an industrial application.

Single-cell oils (SCOs) offer a promising alternative to conventional biodiesel feedstocks. The main objective of this work was obtain SCOs suitable for production from the oleaginous yeast Rhodotorula glutinis R4 using sugarcane vinasse local sugar-derived alcohol industry as substrate. Additionally, crude glycerol evaluated low-cost carbon source replace expensive glucose and strategy integrating bioethanol industries valorization both agro-industrial wastes. achieved high lipid accumulation 88% 60% (w/w) in vinasse-based culture media, containing 10% 25% with (40 g L−1), respectively. When replaced glycerol, showed remarkable (40%) growth (12.58 L−1). fatty acids profile prevalence oleic acid (C18:1), making them synthesis. Biodiesel derived exhibits favorable characteristics, including cetane number (CN = 55) oxidative stability (OS 13 h), meeting international standards (ASTMD6751 EN14214) ensuring its compatibility diesel engines. R. produces contributing circular economy sustainable production.
