Excess biological sludge processing and disposal have a significant impact on the energy balance economics of wastewater treatment operations, receiving environments. Anaerobic digestion is probably most widespread in-plant method globally, since it stabilizes converts biosolids organic matter into biogas, allowing partial recovery their embedded chemical energy. A considerable number studies concerning applicable techniques to improve biogas production, both in quantity quality, include pre-treatment strategies promote disintegration aimed at release solubilisation intracellular compounds, inorganic/biological amendments improving process performance, thermal pre-treatment. As for in-process amendments, iron, micro macro-nutrients, ashes from waste incineration nanoparticles addition been studied improvement enzymatic reactions. Recently, use electrically conductive materials has credited with possibility accelerate stabilize conversion substrates methane. The increasing generation its relative biomethane content by interfacing anaerobic bioelectrochemical systems was also postulated. This review addresses research gap surrounding integration novel technologies, particularly systems, enhance production methane enrichment. While existing focus feasibility, mechanisms, benefits such remain underexplored. By critically evaluating current state art, this identifies potential stability, while highlighting key challenges needs advancing these technologies toward practical implementation.

In situ contaminant degradation and detoxification mediated by microbes minerals is an important element of green remediation. Improved understanding microbe-mineral interactions on the nanoscale offers promising opportunities to further minimize environmental energy footprints site this Perspective, we describe new methodologies that take advantage array multidisciplinary tools─including multiomics-based analysis, bioinformatics, machine learning, gene editing, real-time spectroscopic microscopic computational simulations─to identify key microbial drivers in real environments, characterize dynamic interplay between with high spatiotemporal resolutions. We then reflect how knowledge gained can be exploited modulate binding, electron transfer, metabolic activities at interfaces, develop detoxication technologies combined merits efficacy, material longevity, low impacts. Two main strategies are proposed maximize synergy microbes, including using mineral nanoparticles enhance versatility microorganisms (e.g., tolerance stresses, growth metabolism, directed migration, selectivity, transfer), synthesize regenerate highly dispersed nanostructures desired structural/surface properties reactivity.

High ammonia concentrations in anaerobic degradation systems cause volatile fatty acid accumulation and reduced methane yield, which often derive from restricted activity of syntrophic acid-oxidising bacteria hydrogenotrophic methanogens. Inclusion additives that facilitate the electron transfer or increase cell proximity species by flocculation can be a suitable strategy to counteract these problems, but its actual impact on interactions has yet determined. In this study, microbial cultivation molecular microscopic analysis were performed evaluate conductive (graphene, iron oxide) non-conductive (zeolite) rate acetate propionate highly enriched ammonia-tolerant cultures derived biogas process. All had low lag phase resulted higher (except graphene) degradation.

Microscopy element showed precipitation phosphates biofilm formation all batches except graphene batches, possibly enhancing Overall, concordance responses observed both acetate- propionate-fed highlight suitability addition oxide zeolites enhance conversion high-ammonia processes. KEY POINTS: • promoted A preference for floc was revealed. Microbes colonised surfaces zeolite, not graphene.
