This study presents a sustainably engineered lignin-based biocomposite reinforced with chitosan, designed for multifunctionality, enhanced material performance, and produced <em>via</em> a ‘green’ and simple one-pot synthesis in aqueous medium. The synthesized granular material, <em>i.e.</em> a zwitterionic lignin-chitosan composite (ZLC), was used for the removal of a wide range of chemically diverse contaminants. ZLC showed 80–90% removal of heavy metals such as Cr(<small>VI</small>), Cu(<small>II</small>), and four different cationic and anionic dyes. It was also tested against an array of five PFAS molecules, such as perfluorinated sulfonic and carboxylic acids, showing up to 86% removal for perfluorooctane sulfonic acid (PFOS). All adsorption processes followed the pseudo-second order and Langmuir models. The material also showed antifouling behavior, demonstrating robustness for real-time application. Lastly, ZLC was tested against effluent water matrices, <em>i.e.</em>, wastewater streams from mining areas located in Sweden. The multifunctional adsorption performance of the environment-friendly material, coupled with its ease of production, cost effectiveness, and reusability, indicates that ZLC has a high potential that can garner industrial interest for simplifying multi-step filtration processes.</p>","PeriodicalId":72941,"journal":{"name":"Environmental science.

Untreated waste poses major environmental, economic, and societal challenges, especially affecting agriculture and industry. Addressing this crisis necessitates innovative waste management strategies and sustainable practices to mitigate the impending waste burden on ecosystems and societies worldwide. Recent advancements in biofuels and biochemicals intensified research into the conversion of biogenic waste into bio-carboxylic acid/volatile fatty acids (VFAs), driven by the dual imperatives of sustainable waste management and renewable resource development. This study presents a comparative analysis of three waste streams: cheese whey from the cheese-making industry, lignocellulosic brewery spent grains (BSG), and agricultural by-products like wheat straw (WS) assessing their efficacy in carboxylic acid production by mixed culture fermentation. Each substrate produced a diverse array of carboxylic acids, including acetic, propionic, butyric, valeric, iso-valeric, and caproic acids exhibiting unique fermentation efficiencies in carboxylic acid production. The experimental results reveal distinct fermentation efficiencies, the highest concentration of short-chain carboxylic acids (SCCA) production of 11.84 gCOD per L from CW, alongside a medium-chain carboxylic acid (MCCA) production of 3.95 gCOD per L. Notably, despite the lignocellulosic composition of the substrates, both BSG and WS demonstrated substantial and competitive yields of SCCA and MCCA. Specifically, BSG produced 10.68 gCOD per L of SCCA and 3.54 gCOD per L of MCCA, while WS yielded 11.51 gCOD per L of SCCA and 3.84 gCOD per L of MCCA. These findings highlight the viability of lignocellulosic substrates for carboxylic acid production, suggesting significant opportunities for enhancing bioprocessing strategies in biochemical and industrial applications. Taxonomic analysis of microbial communities showed a significant predominance of <em>Firmicutes</em>, <em>Bacteroidota</em>, and <em>Actinobacteriota</em>. The Clostridiaceae family exhibited dominance across all reactors, with respective abundances of 82.72%, 27.67%, and 61.29%. The BSG uniquely showcased an enrichment of <em>Lactobacillaceae</em> (23.86%), <em>Ruminococcaceae</em> (7.72%), and <em>Prevotellaceae</em> (3.24%). Key genera contributing to carboxylic acid production included <em>Clostridium sensu stricto 1</em>, <em>Romboutsia</em>, and <em>Enterococcus</em>. This diversity highlights the influence of substrate composition on microbial community structure, highlighting the intricate relationships between substrate nature and microbial metabolites suggesting that strategic substrate selection could optimize fermentation efficiency and enhance product yield.</p>","PeriodicalId":72941,"journal":{"name":"Environmental science.

While the FC showed limited seasonal variability, DGT results revealed a strong positive correlation between REE atomic number and lability during the dry season (<em>r</em> = 0.91). This trend was not observed in the wet season, likely due to increased hydrological variability, colloidal mobilisation, and complexation with dissolved organic carbon (DOC). The transport of REE in the PSRB was strongly influenced by colloids and the presence of Fe, Mn, and Si, particularly affecting light REE. The integration of DGT concentrations with equilibrium-based chemical speciation modelling enabled a more comprehensive assessment of REE speciation in the PSRB. Positive La, Gd, and Yb anomalies at polluted sites indicate anthropogenic inputs, with La and Gd as potential emerging contaminants.
