“…The sDFMFC demonstrated a diversified microbial population for optimal organic substrate microbial conversion. The findings suggest that the sDFMFC could be a promising single reactor process for producing H 2 and energy from a variety of biomass feedstocks while maintaining the individual DF and MFC processes' efficiency [59].…”

Nowadays, the world is experiencing an energy crisis due to extensive globalization and industrialization. Most of the sources of renewable energy are getting depleted, and thus, there is an urge to locate alternative routes to produce energy efficiently. Microbial fuel cell (MFC) is a favorable technology that utilizes electroactive microorganisms acting as a biocatalyst at the anode compartment converting organic matter present in sewage water for bioelectricity production and simultaneously treating wastewater. However, there are certain limitations with a typical stand-alone MFC for efficient energy recovery and its practical implementation, including low power output and high cost associated with treatment. There are various modifications carried out on MFC for eliminating the limitations of a stand-alone MFC. Examples of such modification include integration of microbial fuel cell with capacitive deionization technology, forward osmosis technology, anaerobic digester, and constructed wetland technology. This review describes various integrated MFC systems along with their potential application on an industrial scale for wastewater treatment, biofuel generation, and energy production. As a result, such integration of MFCs with existing systems is urgently needed to address the cost, fouling, durability, and sustainability-related issues of MFCs while also improving the grade of treatment received by effluent.

“…The process requires converting the biomass to gas such as hydrogen or carbon monoxide before it can be utilized, so the cells are essentially unable to process biomass directly. There have been some studies absorbed on the fuel cell systems meeting with HALUB (Table 4 ) [ 164 ]. A study reported that the highest output power densities ( P max ) reached 12.3 and 41.8 mW cm −2 with open-circuit voltages of 560 and 1560 mV, respectively, through a liquid flow fuel cell under acidic and alkali conditions in processing of lignocellulosic biomass [ 165 ].…”

We conceptualize bioresource upgrade for sustainable energy, environment, and biomedicine with a focus on circular economy, sustainability, and carbon neutrality using high availability and low utilization biomass (HALUB). We acme energy-efficient technologies for sustainable energy and material recovery and applications. The technologies of thermochemical conversion (TC), biochemical conversion (BC), electrochemical conversion (EC), and photochemical conversion (PTC) are summarized for HALUB. Microalgal biomass could contribute to a biofuel HHV of 35.72 MJ Kg−1 and total benefit of 749 $/ton biomass via TC. Specific surface area of biochar reached 3000 m2 g−1 via pyrolytic carbonization of waste bean dregs. Lignocellulosic biomass can be effectively converted into bio-stimulants and biofertilizers via BC with a high conversion efficiency of more than 90%. Besides, lignocellulosic biomass can contribute to a current density of 672 mA m−2 via EC. Bioresource can be 100% selectively synthesized via electrocatalysis through EC and PTC. Machine learning, techno-economic analysis, and life cycle analysis are essential to various upgrading approaches of HALUB. Sustainable biomaterials, sustainable living materials and technologies for biomedical and multifunctional applications like nano-catalysis, microfluidic and micro/nanomotors beyond are also highlighted. New techniques and systems for the complete conversion and utilization of HALUB for new energy and materials are further discussed.

“…On the other hand, biomass power generation, heat supply, hydrogen production, and other forms of utilization are also gaining attention, which occupied parts of the market share of biomass feedstocks. According to the literature survey, biomass power generation has maintained a steady growth trend, with 132.6 billion kWh of global biomass power generation in 2020, maintaining a trend of 19.4% growth to continue [181]; Biomass heating through biomass boiler heating and biomass cogeneration [182], which can achieve a greater degree of green and low-carbon compared with fossil energy sources such as coal and natural gas. Therefore, the development of biomass heating is strongly supported by the government.…”

Energy consumption from transport has been increasing at a fast rate and become a major sector, which takes 29% of total global energy demand. Since transport energy consumption primarily relies on fossil fuels, it has resulted in serious carbon emissions and environmental degradation. Moreover, the volatility prices of fossil fuel and unstable international security have attracted keen interest for many developing and industrialized countries looking for sustainable and clean alternatives. Liquid biofuels, including but not limited to bioethanol, biodiesel, bio-jet fuel, are considered as the most promising alternative and more expansive role in powering sustainable transport, for its carbon neutral and low-emissions properties. Liquid biofuels contribute 4% of transport in 2020 and have been foreseen to continuously grow. Liquid biofuels can be produced by diverse technologies and commercialized in various ways, easy-adapt to technical and policy challenges. Major challenges include technical bottleneck, initial and operational cost, byproduct treatment, and associated environmental concern. This paper critically reviews: (1) Categories and production of different liquid biofuels; (2) Application scenarios of liquid biofuels; (3) Environmental impact assessment of liquid biofuels; (4) Opportunities and challenges of liquid biofuels; (5) Future perspectives. Each type of liquid biofuel requires specific production processes and has a strong correlation with biomass raw materials. Liquid biofuels find extensive applications in transportation, aviation, and other functional domains. In addition, the life cycle assessment of liquid biofuels is carried out from the numerous aspects of raw materials, pretreatment, production process, and application. Furthermore, this study analyzes the related policies, highlighting the challenges associated with the unstable supply of clean energy, raw materials, and quality control. Finally, the future perspectives of liquid biofuels were presented. This comprehensive review aims to provide a systematic understanding of liquid biofuels, covering their production and applications from multiple perspectives, while offering insights into future developments.
