Biobased short chain fatty acid production - Exploring microbial community dynamics and metabolic networks through kinetic and microbial modeling approaches

Biotechnology Advances, Journal Year: 2024, Volume and Issue: 73, P. 108363 - 108363

Published: April 22, 2024

In recent years, there has been growing interest in harnessing anaerobic digestion technology for resource recovery from waste streams. This approach evolved beyond its traditional role energy generation to encompass the production of valuable carboxylic acids, especially volatile fatty acids (VFAs) like acetic acid, propionic and butyric acid. VFAs hold great potential various industries biobased applications due their versatile properties. Despite increasing global demand, over 90% are currently produced synthetically petrochemicals. Realizing large-scale VFA streams offers significant eco-friendly opportunities but comes with several key challenges. These include low yields, unstable acid compositions, complex expensive purification methods, post-processing needs. Among these, yield composition stand out as most critical obstacles impacting economic viability competitiveness. paper seeks offer a comprehensive view combining complementary modeling approaches, including kinetic microbial modeling, understand workings communities metabolic pathways production, enhance efficiency, regulate profiles through integration omics bioreactor data.

Chemical Valorization of Textile Waste: Advancing Sustainable Recycling for a Circular Economy

ACS Omega, Journal Year: 2025, Volume and Issue: unknown

Published: March 19, 2025

As textile production continues to grow worldwide, managing the mounting waste generated by this industry is becoming an urgent environmental concern. Globally, over 92 million tons of are produced annually, much which incinerated or disposed in landfills, contributing greenhouse gas emissions, soil and water contamination, ecosystem harm. This review explores how chemical biotechnological methods, such as acid hydrolysis (achieving up 70% glucose recovery) enzymatic recycling (reducing energy consumption approximately 20% compared conventional methods), can transform into valuable resources, fostering a shift toward circular economy that minimizes reliance on virgin materials. However, diverse nature waste─particularly mixed fibers materials treated with various finishes additives─adds complexity processes, often necessitating specific pretreatment steps ensure both efficiency economic viability. Scalable solutions advanced solvent recovery systems, optimized techniques, fluidized-bed pyrolysis (which increase bio-oil yields 25% fixed-bed reactors) play crucial roles making more sustainable adaptable at industrial scale. By addressing these technical financial challenges, improve sustainability practices, reducing resilience. also suggests several future directions enhance scalability compatibility goals, highlighting potential for technologies create secondary support greener practices management. Through continued innovation commitment better balance resource feasibility, unlocking substantial opportunities mitigate impact resource-efficient, future.

Bio-physical pre-treatments in anaerobic digestion of organic fraction of municipal solid waste to optimize biogas production and digestate quality for agricultural use

Waste Management, Journal Year: 2024, Volume and Issue: 189, P. 114 - 126

Published: Aug. 24, 2024

This study optimized the anaerobic digestion (AD) of separated collected organic fractions municipal solid waste (OFMSW) to produce energy and digestate as biofertilizer. Due OFMSW's partial recalcitrance degradation, enzymatic (UPP2, MCPS, USC4, USE2, A. niger) physical (mechanical blending, heating, hydrodynamic cavitation) pre-treatments were tested. Experimental modeling approaches used compare AD performance regarding sustainability quality. Digestate was into liquid fractions, then chemically physically characterized by investigating nutrient release mechanisms. Principal Component Analysis applied, equally weighing productions. Unlike previous studies focusing only on biogas, this evaluated effects both biogas production, viewing a biorefinery process for urban valorization. Results showed that all energetically sustainable, but yielded digestates richer in nutrients (increase 80% N, 200% P 150% K compared OFMSW) with greater matter degradation pre-treatments. The fraction from had higher concentrations, while those more balanced content, making them suitable fertigation.
