In the past decades, considerable attention has been directed toward anaerobic digestion (AD), which is an effective biological process for converting diverse organic wastes into biogas, volatile fatty acids (VFAs), biohydrogen, etc. The microbial bioprocessing takes part during AD of substantial significance, and one crucial approaches deep adequate understanding manipulating it different products microbiology. Due to highly complexity microbiome, critically important study involved microorganisms in AD. recent years, addition traditional methods, novel molecular techniques meta-omics have developed provide accurate details about communities Better microbiomes could guide us identifying controlling various factors both improving diverting metabolic pathway production selective bio-products. This review covers platforms that results final from microbiological point view. also highlights distinctive interactions occurring among communities. Furthermore, assessment these existing digesters discussed more insights their structure, dynamics, pathways. Moreover, affecting each platform are highlighted. Finally, provides some applications bio-products deals with challenges future perspectives

Intensification of yam-starch based biodegradable bioplastic film with bentonite for food packaging application

Environmental Technology & Innovation, Год журнала: 2021, Номер 25, С. 102180 - 102180

Bioplastics are gaining more attention over synthetic plastics owing to their non-hazardous properties. Earlier studies had reported the biodegradation and solubility properties of yam starch-based bioplastic; however, its mechanical with reinforcement were not studied. The present work focuses on development (Dioscorea) bioplastic film glycerol as a plasticizer. Different concentrations bentonite (0.5, 1, 1.5 %w/w) was reinforced biofilms prepared by solvent casting method. developed films systematically characterized using scanning electron microscope (SEM), Fourier transforms infrared spectroscopy (FTIR), contact angle, tensile testing, soil water degradation, vapor transmission rate (WVTR), swelling, solubility, chemical testing. SEM micrographs show particles homogeneously distributed in starch matrix. hydrophilicity increased addition bentonite. FTIR spectra revealed that strengthened O–H bond Si–O–Si bond, which improved strength. It observed 1.5% concentration exhibited maximum degradation lowest molecule absorption. This is due intercalated silicate layer films. Also, impermeable salt acidic medium but remained ineffective basic medium. study has effectively property, making it potential replace plastic food packaging applications.

Nano-Biochar as a Sustainable Catalyst for Anaerobic Digestion: A Synergetic Closed-Loop Approach

Catalysts, Год журнала: 2022, Номер 12(2), С. 186 - 186

Опубликована: Фев. 1, 2022

Nowadays, the valorization of organic wastes using various carbon-capturing technologies is a prime research area. The anaerobic digestion (AD) technology gaining much consideration in this regard that simultaneously deals with waste and bioenergy production sustainably. Biochar, well-recognized carbonaceous pyrogenic material possessing broad range inherent physical chemical properties, has diverse applications fields agriculture, health-care, sensing, catalysis, carbon capture, environment energy. nano-biochar-amended approach intensively been explored for past few years. However, an inclusive study multi-functional roles biochar mechanism involved enhancing biogas via AD process still need to be evaluated. present review inspects significant role addition kinetics involved, further focusing on limitations, perspectives, challenges technology. Additionally, techno-economic analysis life-cycle assessment biochar-aided closed-loop integration possible improvement practices are discussed.

Emerging contaminants in biosolids: Presence, fate and analytical techniques

Emerging contaminants, Год журнала: 2022, Номер 8, С. 162 - 194

Опубликована: Янв. 1, 2022

Emerging contaminants (ECs) represent a small fraction of the large chemical pollution puzzle where wide variety potentially hazardous chemicals reach environment, and new compounds are continuously synthesized released in wastewater treatment plants ultimately effluent biosolids. ECs have been classified into various categories; however, this article focuses on fate major categories, namely pharmaceutical personal care products (PPCPs), per-and poly-fluoroalkyl substances (PFAS), flame retardants, surfactants, endocrine-disrupting (EDCs), microplastics (MPs). These when discharged to sewer downstream can undergo further transformations either degrade, persist or convert by-products which potential some cases be more hazardous. Because dangerous impacts availability these information behavior pollutants is highly important develop strategies, such as regulation imported Australia Australian consumer goods environmental policies mitigate them sustainable way. Moreover, advanced technologies required for detection identification novel emerging environment at ultra low levels. The application chromatographic techniques coupled with mass spectroscopy has provided attractive breakthroughs detect contaminants. However, it crucially understand sensitivity robustness analytical dealing complex matrices In addition, most literature was focused selected family existing reviews paid less attention examine formation metabolites during process their ecosystem. This review presents an overview presence different classes around world, quantification from sources like (influents effluents), sludge transformation process, intermediate also critically discussed. Three steps analysis include sample preparation, extraction clean-up, analysis; hence, methods employed thoroughly discussed, advantages limitations highlighted. comprehensive believed enhance understanding sewage would useful readers relevant communities stakeholders investigate maximize destruction ECs.
