The population explosion has put the world into a global energy and water crisis. Bioelectrochemical cells serve as sustainable solutions to the said problems. Bioelectrochemical cells (BECs) can be categorized as microbial fuel cells (MFC), microbial electrolysis cells (MEC), microbial electrosynthesis cells (MESC), etc. The working principle of these bioelectrochemical cells utilizes biological catalysts to catalyze electrochemical reactions within the cell. This catalyst may extract electrons from biomass and generate electricity or help convert waste materials into useful/value-added products such as green hydrogen, methane, and acetate, etc. The products formed can be used for fuel purposes or as a substrate for other BECs. Over the past two decades, extensive progress has been made using advanced electrode modifications, optimized reactor configuration, and integration with other treatment facilities to overcome scaling constraints of these systems. Despite these developments, challenges remain in terms of efficiency, scalability, and economic viability. In this review, recent innovations in BECs to maximize power and resource recovery from different wastes have been explored, along with technical barriers faced during large-scale commercialization.

Incineration offers an effective way to reduce MSW volume and extend landfill capacity, yet the resulting MSW incineration ashes (MSWIA) pose disposal challenges. Recent studies suggest their potential in construction materials. This work investigates the feasibility of incorporating MSW bottom ash (MSWIBA) and fly ash (MSWIFA) into paver block production for low-volume traffic areas. The ashes were characterized for particle size distribution, mineralogy, morphology, and chemical composition using laser particle size analysis, X-ray diffraction, scanning electron microscopy, and X-ray fluorescence respectively. M30 grade concrete prepared with 20% natural sand replaced by MSWIBA and 10% coal fly ash replaced by MSWIFA achieved 28-day mechanical performance comparable to conventional mixes. Durability tests, including water permeation, rapid chloride permeability, and abrasion resistance, confirmed that MSWIBA substitution did not compromise concrete’s quality. Leaching analysis indicated heavy metal concentrations within USEPA regulatory limits, demonstrating effective immobilization and environmental safety. The embodied energy of paver blocks was ~1812 MJ/m<sup>3</sup> for both control and MSWI-based mixes, with cement contributing over 90% of the total. Moreover, paver blocks incorporating up to 20% MSWIBA and 10% MSWIFA met the requirements of IS 15658:2006.

Although the number of participating fishermen does not directly impact enterprise decision-making, their increased involvement enhances overall governance effectiveness.
