In response to increasing global waste generation due population growth, urbanization, and industrialization, wastewater treatment operations should shift from being solely energy consumers becoming producers by harnessing sludge (WWS). This approach holds great potential for meeting demands addressing the challenges of treatment. The recovery heat electrical WWS offers a viable solution reduce costs within WWTPs. Thermochemical technologies such as pyrolysis, gasification, combustion hold their efficiency, reaction times, retrieval capabilities. These demonstrate feasibility in terms operational costs, circular economy principles, socio-environmental impact, thanks ongoing advancements waste-to-energy research. review aims explore recovering bioenergy (biogas or syngas) generate energy, including heat, electricity, other innovative products. article provides critical comprehensive examination thermochemical technologies, taking into account technological, economic, factors. It then presents integration techniques that effectively combine anaerobic digestion with conversion enhance syngas, biogas, flue-gas energy. results this study underscore significant sludge-to-energy schemes.

A compact three-in-one water treatment process, combining a flocculant, fibrous super-bridging agent, and screen-based floc retention system, simultaneously improves sludge dewatering. The presence of materials allows for the formation very large flocs, efficient separation via screening (without settling), dewatering through press-filter system. implementation this process is possible due to fiber-based flocs. containing fibers was subsequently dewatered using press filter without further chemical addition. use also significantly improved removal total organic carbon, nanoplastics, microplastics. This could be used decentralized in drinking wastewater applications small cities, marginalized communities, developing countries. which performs dewatering, would reduce risks associated with mismanaged environment human health.

Abstract Oil sludge is a solid organic waste generated during the extraction and transport of petroleum resources. In this paper, initially, types oil potential hazards are discussed. On basis, disposal process microwave pyrolysis for generating three‐phase products (gas, light oil, residual carbon) recycling put forward, through which recycled reused, pollution to environment decreased. To elevate reaction rate raise yields gas liquid four catalysts (montmorillonite‐Ca‐based, montmorillonite‐Na‐based, kaolinite, chlorite) were introduced experimentally dissect heating rate, production pyrolysis. The results demonstrated that was prominently enhanced after adding catalysts, contents also increased conspicuously. combustible content in (H 2 + CH 4 CO) by 17.624 wt.% (montmorillonite Na‐based), 9.511 (chlorite), 12.28 (kaolinite), 15.164 Ca‐based), respectively, compared blank group. clay–metal mineral particularly montmorillonite Na‐based, facilitated decomposition, augmented low‐carbon number straight‐chain hydrocarbons alcohols, improved quality products.

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.
