“…Zn ions through the corrosion and dissolution of ENMs. Few studies demonstrated the toxic effect of nano-ZnO on the reduction of biogas production from sludge digestion process(Nguyen et al 2015) and simulated bioreactor landfills(Temizel et al 2017), however, Nguyen et al (2015 showed the inhibition can be overcome when the exposure concentration of nano-ZnO was in the tolerable range, such as 100 and 500 mg L -1 . Additionally,Mu et al (2011) indicated that higher concentrations of nano-ZnO decreased the activities of protease and coenzyme F420, and the abundance of methanogenesis Archaea.…”

Significant knowledge and data gaps associated with the fate of product-embedded engineered nanomaterials (ENMs) in waste management processes exist that limit our current ability to develop appropriate end-of-life management strategies. This review paper was developed as part of the activities of the IWWG ENMs in Waste Task Group. The specific objectives of this review paper are to assess the current knowledge associated with the fate of ENMs in commonly used waste management processes, including key processes and mechanisms associated with ENM fate and transport in each waste management process, and to use that information to identify the data gaps and research needs in this area. Literature associated with the fate of ENMs in wastes was reviewed and summarized. Overall, results from this literature review indicate a need for continued research in this area. No work has been conducted to quantify ENMs present in discarded materials and an understanding of ENM release from consumer products under conditions representative of those found in relevant waste management process is needed. Results also indicate that significant knowledge gaps associated with ENM behaviour exist for each waste management process investigated. There is a need for additional research investigating the fate of different types of ENMs at larger concentration ranges with different surface chemistries. Understanding how changes in treatment process operation may influence ENM fate is also needed. A series of specific research questions associated with the fate of ENMs during the management of ENM-containing wastes have been identified and used to direct future research in this area.

“…Temizel et al (2017) studied the effect of nano-ZnO on biogas generation from simulated landfills over one year. They demonstrated up to 99% of nano-ZnO was retained in the waste matrix, leading to a decrease in biogas production of 15% [ 273 ]. Incineration is one of the important strategies for sewage sludge management.…”

Biosensors often combine biological recognition elements with nanomaterials of varying compositions and dimensions to facilitate or enhance the operating mechanism of the device. While incorporating nanomaterials is beneficial to developing high-performance biosensors, at the stages of scale-up and disposal, it may lead to the unmanaged release of toxic nanomaterials. Here we attempt to foster connections between the domains of biosensors development and human and environmental toxicology to encourage a holistic approach to the development and scale-up of biosensors. We begin by exploring the toxicity of nanomaterials commonly used in biosensor design. From our analysis, we introduce five factors with a role in nanotoxicity that should be considered at the biosensor development stages to better manage toxicity. Finally, we contextualize the discussion by presenting the relevant stages and routes of exposure in the biosensor life cycle. Our review found little consensus on how the factors presented govern nanomaterial toxicity, especially in composite and alloyed nanomaterials. To bridge the current gap in understanding and mitigate the risks of uncontrolled nanomaterial release, we advocate for greater collaboration through a precautionary One Health approach to future development and a movement towards a circular approach to biosensor use and disposal.

“…Three distinct focus -ZnO NPs (1.35 and 150 g/Kg complete suspended strong TSS were added to WAS .Although the option of 1mg/g TSS ZnO NPs showed a real impact on the creation of methane ,the option of 35 TSS at 150mg/g diminished the methane production by 81.7 % and the benchmark group by 24.9% . Unsar and Perendeci [61] focused on the effect of Al2O3 NPs on the creation of biogas from squander initiated ooze over the long and present moment. A 48-day long haul biochemical methane possible test and a 72-hour momentary anaerobic restraint test were done by the creators.…”

Anaerobic digestion is a biochemical process used globally to convert the organic matter present in wastes into a process enhancing biogas production. Biogas production via anaerobic digestion (AD) of wastes is a very attractive, yet a challenging task. The slow rate of biodegradation and the presence of impurities in biogas expose the whole process to several risks. However, the addition of nanoparticles (NPs) can influence the performance and stability of the AD process. AD is a complex biochemical process which converts complex organic wastes into a gas mixture containing methane (CH4), carbon dioxide (CO2), water vapor, hydrogen sulfide (H2S), hydrogen, and ammonia. The sluggish rate of biodegradation of complex organic substrates, i.e., ligocellulosic substrates, limits the performance and efficiency of the AD process. Furthermore, because of hazardous components that may impair the efficiency of the AD process, such as organic matter and ammonia in wastewater and various organic, substrates may need pre-treatment such as thermal and acidic/alkaline. Nanotechnology a growing impact on a wide range of microbiological, pharmaceutical, and pure technological applications. The current application in production benefits from producing bioenergy from biomass is still highly limited. This work examines the effects of NPs additions on the AD. In addition, this research covers the benefits and the drawbacks of nanoparticles in producing of biogas.
