Abstract The development of technologies for replacing formaldehyde‐based adhesives and disposing sewage sludge (SS) are two standing issues high interest to the academy industry. This study reports production formaldehyde‐free wood bio‐adhesive using hydrochar from hydrothermal carbonization SS aided by sodium periodate (NaIO4) oxidation. performance bio‐adhesives can meet requirements Chinese National Standard GB/T 9846‐2015 (≥0.7 MPa). aldehyde group forms after NaIO4 treatment hydrochar, which should benefit adhesion performance. However, oxidation process also breaks some polysaccharides' carbon chains, disrupting extracellular polymeric substances (EPS) structure in forming small molecular compounds. As a result, wet shear strength value decreases, but water resistance increases. Nevertheless, interaction between active functional groups (e.g., amine groups) during hot‐pressing promotes In addition, doping polyethyleneimine, cross‐linked network be further enhanced, improving resistance. Hence, introducing is key step bio‐adhesives, proving as novel practical approach valorize producing adhesives.

Abstract This study reports the use of deep‐eutectic‐solvent‐ (DES‐) assisted hydrothermal carbonization (HTC) to disrupt floc structure sewage sludge (SS) for deep carbonization, with resulting hydrochars employed in preparation formaldehyde‐free plywood bioadhesives. Sewage‐sludge‐based bioadhesive exhibits an excellent wet shear strength, complying requirements Chinese national standard GB/T 9846–2015 (≥0.7 MPa). The molecular weight proteins and formation covalent bonds via dehydration have a notable role improving adhesive performance (wet strength).

Currently, there is a growing interest in transforming wastewater treatment plants (WWTPs) into resource recovery plants. Microorganisms aerobic granular sludge produce extracellular polymeric substances (EPS), which are considered sustainable resources to be extracted and can used diverse applications. Exploring applications other high-value materials, such as adhesives, will not only enhance the valorization potential of EPS but also promote recovery. This study aimed characterize water-soluble fraction from collected at demonstration plant Netherlands based on its chemical composition (amino acids, sugar, fatty acids) propose proof-of-concept for use an adhesive. comprises mixture biomolecules, proteins (26.6 ± 0.3%), sugars (21.8 0.2%), acids (0.9%). The exhibited shear strength reaching 36–51 kPa across pH range 2–10 without additional treatment, suggesting application findings this provide insights concept excess WWTPs.

Biofilms play important roles in water technologies such as membrane treatments and activated sludge. The extracellular polymeric substances (EPS) are key components of biofilms. However, the precise nature these how they influence biofilm formation behavior remain critical knowledge gaps. EPS produced by many different microorganisms span multiple biopolymer classes, which each require distinct strategies for characterization. biopolymers additionally associate with other to form insoluble complexes. Here, we explore recent progress toward resolving structures functions EPS, where a shift towards direct functional assessments advanced characterization techniques is necessary. This will enable integration better microbial community omics analyses understand biosynthesis pathways create further opportunities control valorization.
