Utilization of organic community wastes towards deriving sustainable renewable energy and adequate disposal the residual has been an important topic investigation. Anaerobic digestion co-digestion rice-derived food waste animal manure for biogas generation is crucial from view-point consumption. This paper presents extensive review recent contributions in related areas. The critical physico-chemical parameters involved such process are analyzed, including temperature, carbon–nitrogen ratio, microorganisms, pH, substrate characteristics, loading rate, hydraulic retention time, volatile fatty acids, ammonia, light/heavy metal ions. Studies implied that optimum yield production could be achieved only when values exist specific ranges. Few studies highlighted use emerging techniques micro-aerobic system, additives, laser radiation, bio-electrochemical field, among others efficiency enhancement yield. entire study provided a set conclusions future research directives as well proposed.

Abstract Anaerobic digestion (AD) is a crucial bioenergy source widely applied in wastewater treatment. However, its efficiency improvement hindered by complex microbial communities and sensitivity to feedstock properties. We, thus, propose hybrid quantum-classical machine learning (Q-CML) regression algorithm using quantum circuit (QCL) strategy. Combining variational with classical optimiser, this approach predicts biogas production from operational data of 18 full-scale mesophilic AD sites the UK. Tailored for noisy intermediate-scale (NISQ) devices, low-depth QCL model outperforms conventional methods ( R ²: 0.53) matches performance multi-layer perceptron (MLP) regressor 0.959) significantly fewer parameters better scalability. Comparative analysis highlights advantages superposition entanglement capturing intricate correlations data. This study positions Q-CML as cutting-edge solution optimising processes, boosting energy recovery, driving circular economy.

This review focuses on the integration of thermochemical and biochemical processes as a transformative approach to biomass conversion. By combining technologies such anaerobic digestion, hydrothermal liquefaction, pyrolysis, syngas fermentation, this highlights how hybrid systems maximize resource recovery improve energy efficiency. Key examples include use digestate from digestion feedstock for pyrolysis or carbonization, enhancing biochar hydrochar production while improving nutrient recycling. Similarly, fermentation with gasification demonstrates products can be further valorized into biofuels under milder conditions. also addresses reuse by-products, aqueous phase processes, in algae cultivation, showcasing circular potential these systems. emphasizing technical economic synergies integrating diverse technologies, paper outlines clear pathway industrial-scale adoption, contributing sustainable reduced greenhouse gas emissions.

Anaerobic digestion (AD), or biogas technology, is an optimal method for municipal organic waste (MOW) treatment, recovering both material and energy. This study takes a life cycle assessment perspective examines the economic environmental impacts of BIO facility in Minamisanriku Town, Japan, which has utilized MOW (kitchen/food surplus sludge from sewage) as local biomass resources since 2012. Stakeholder interviews were conducted to gather data on flows impacts. Scenario analysis considered various conditions, such pre- post-operation facility, use non-use digestate liquid fertilizer, facility’s 100% operational efficiency. The results indicate that full operation marketing value-added products, branded rice grown using could significantly reduce greenhouse gas (GHG) emissions, lower integrated costs, improve regional economy, increase net income. In business usual (BAU) scenario with 56% rate there over 10% improvement compared pre-operation baseline. underscores importance maximizing utilization develop uses by enhancing, extending, expending stakeholder collaboration.

Additives for anaerobic digestion (AD) can play a significant role in optimizing the process by increasing biogas production, stabilizing system, and improving digestate quality. The of additives largely boils down to, among others, enhancing direct interspecies electron transfer (DIET) between microbial communities, resulting improved syntrophic interactions, adsorption toxic substances that may inhibit activity, stability accelerating decomposition complex organic materials, thereby rate hydrolysis. Through aforementioned action, significantly affect AD performance. function these materials varies, from activity to maintaining optimal conditions protecting system inhibitors. choice should be carefully tailored specific needs digester maximize benefits ensure sustainability. In light considerations, this paper characterizes most commonly used their combinations based on comprehensive review recent scientific publications, including report results conducted studies. publication features chapters describe carbon-based conductive metal oxide nanomaterials, trace metal, biological additives, enzymes microorganisms. It concludes with summarising reports various discussing functional properties, as well advantages disadvantages. presented is substantive concise analysis latest knowledge process. application characterized great potential; hence, subject matter very current future-oriented.

Anaerobic digestion (AD) of food waste (FW) is considered an environmentally sustainable process that can divert the disposal FW to landfill and prevent greenhouse gas (GHG) emissions in managing FW. Although several studies have attempted demonstrate AD FW, low methane yields a high incidence instability been reported due rapid generation accumulation volatile fatty acids (VFAs). This paper reviews recent research development with variation composition, such as carbon-to-nitrogen (C/N) ratio and, consequently, effect its physicochemical composition on performance yields. The highlights significance optimizing anaerobic co-digestion (AcoD) carbon-rich substrates garden (GW) and/or addition trace elements strategies improve from review focuses factors effecting feasibility organics (FOGO) substrate for production. also critically analyses prospects enhancement biomethane yield by optimizations impactful parameters. progress related these methods identifying existing limitations efficient FOGO are key findings this review. assesses impact nanotechnology digester. integration FO GO processes has demonstrated enhanced biogas yields, improved stability, better management outcomes compared either alone. Despite advantages, challenges feedstock variability, optimization, need advanced pretreatment remain. Addressing issues through continued technological innovations will be crucial maximizing efficiency scalability systems. Moreover, economic policy frameworks supporting further promote broader adoption.

A variety of mathematical models have been developed to simulate the biochemical and physico-chemical aspects anaerobic digestion (AD) process treat organic wastes generate biogas. However, all these models, including most widely accepted implemented Anaerobic Digestion Model No.1, remain incapable adequately representing material balance AD are therefore inherently conservation. The absence robust mass conservation constrains reliable estimates any kinetic parameters being estimated by regression empirical data. To address this issue, present work involved development a “framework” for mass-conserving atomistic model which is capable conservation, with relative error in range machine precision value an atom ±0.02% whilst obeying Henry’s law electroneutrality principle. Implementing Excel spreadsheet, study calibrated using data derived from batch studies. Although shows high fidelity as assessed via inspection, considering several constraints drawbacks implementation platform, also provides non-exhaustive list limitations further scope development.

Vinasse poses considerable environmental problems due to its complex composition of organic matter, minerals, and toxic compounds. If discharged into the environment without treatment, it can cause adverse impacts on ecosystems. This research investigated effectiveness an integrated treatment system involving upflow anaerobic sludge blanket (UASB) reactor modified Bardenpho process (MBP) for purifying synthetic vinasse. The study lasted 167 days, during which UASB-MBP processed untreated vinasse with loading rates (OLR) ranging from 1.6 12.5 kgCOD/m
