Abstract As an interspecies signalling molecule, indole that is also regulating the microbial community quorum sensing (QS) can be indispensable factor to influence performance of anaerobic digestion process. Mainly released by Gram-negative bacteria, impact regulation towards methane production in such system hardly exposed. This research intends analyse affected fluctuations waste sewage sludge (WSS) response QS repression and its analogs: 4-fluoroindole (4-FI), 5-fluoroindole (5-FI), 6-fluoroindole (6-FI), 3- indoleacetic acid (3-IAA), indoleacrylic (3-IARA). Illumina MiSeq platform was utilized delve into active microbes, with ribonucleic (RNA) used as template generate 16S metagenomic library. results, all them inhibit generation even substrates (acetic acid) availability, this phenomenon led slight imbalance Gram-positive/negative bacterial composition inactivation viable core fermenters: Firmicutes, Proteobacteria Chloroflexi. Plus, following compounds, indole, 3-IAA, 6-FI directly disrupted productions both acetoclastic hydrogenotropic methanogenic archaea. Methanosarcina acetivorans C2A a prominent synthesizer characterised terms viability synthesis activity against them. Notably, non-viable presence thus lowering production. From here, affirmation on direct indirect inhibitions archaea derivatives will pave way for valuable future exploration mechanism mapping during methanogenesis.

Microplastics are pollutants formed from fragmented plastics and also industrially manufactured for personal care cosmetic products. They range 1 µm to 5 mm ubiquitous in the environment due their tiny size, lightweight, wide applications. Ecotoxicological studies have shown that they can induce multiple harmful effects on exposed organisms humans. Wastewater treatment plants (WWTPs) drawn interest of researchers regulatory bodies worldwide as a point source microplastics discharge environment. In absence standardized methodology, microplastic monitoring WWTPs has been marked by distinct variations sample processing analytical procedures which limit comparison results. This review provides detailed analysis methods patterns, analytical, size characterization, quantification WWTPs. According procedural steps extraction reported reviewed studies, 12 patterns three categories approaches (single, dual, multiple) were identified. quantified using gravimetry method, mass sub-sample method (based extrapolation) with latter being most applied technique. Microplastic characterization accomplished two main methods: sieve-based technique computing-based

Biomass-to-biofuel conversion represents a critical component of the global transition to renewable energy. One most accessible types biomass is sewage sludge (SS). This by-product from wastewater treatment plants (WWTPs) contains microplastics (MPs) originating household, industrial and urban runoff sources. Due their small size (<5 mm) persistence, MPs present challenge when they are removed systems, where mainly accumulate (~90%). The presence in SS poses environmental risks biosolids applied as fertilizer agriculture or incinerated for purpose energy production. key problem efficient reliable identification reduction due lack standardized procedures. methods might involve physical, chemical, biological, hydrothermal approaches, including carbonization (HTC). HTC produces hydrochar (HC), solid biofuel, presents cutting-edge approach that simultaneously addresses secondary microplastic pollution biomass-derived In this article, we review briefly content different countries, promising method removal SS. conclusion, (i) effectively reduces abundance biosolids, (ii) an improved source energy, (iii) contributes circular management.

This review highlights the significant interaction between microplastic (MP) pollution and its impact on wastewater treatment systems, focusing optimizing biogas production. We explore various sources of MPs, including tire-derived their introduction into environments. delves mechanical physicochemical challenges MPs pose in processes, emphasizing need for comprehensive mitigation strategies. The biological effects microbial consortia essential production are analyzed, particularly how these pollutants interfere with each stage anaerobic digestion—hydrolysis, acidogenesis, acetogenesis, methanogenesis—and, consequently, generation. examine MPs’ quantitative qualitative impacts output rates, uncovering disrupt activity stages. also discusses novel strategies combining different sludge pretreatment methods MPs. Our goal is to enhance sustainability management by promoting efficient environmental protection presence persistent MP contamination.

The treatment and resource utilization of sludge from municipal sewage plants is an important environmental issue. Cement kiln co-processing offers a promising solution, but challenges remain, particularly regarding properties feasibility in systems. This study analyzes the characteristics three pretreated sludges: mechanically dewatered sludge, deeply lime-dried sludge. Using techniques such as thermogravimetric analysis (TGA) X-ray diffraction (XRD), this investigates their calorific values raw material utilizability co-processing. As moisture content decreases interstitial to bound water, energy consumption per ton evaporated water rises, below 30%. At 10 °C/min heating, for at 80%, 30%, 10% was 3573, 8220, 34,751 kJ/kg, respectively; 60%, 10%, were 4398, 7550, 11,504 kJ/kg. Keeping above 30% before entry reduces use enhances value. Sludge depends on its pretreatment. ash composition resembles iron-rich materials, while aligns more with limestone. utilizable 23.3%, 8.1%, 46.3%, respectively, showing highest potential. provides insights into potential cement kilns, offering scientific technical support practical applications.
