Summary: This paper critically discusses the importance of cooperative environmental governance (CEG) for efficient waste management and waste-to-energy (WtE) generation in the context of growing urban South Asia. Focusing on Bangladesh, India and Pakistan experiences, the paper reveals that even though much progress has been done in the urbanisation in the selected countries, the process of waste management (mainly municipal solid waste) has not been effective due to low level of local inclusion. As a result, the WtE generation potential has not been realised to its fullest. In addition, it has been argued that institutional and social reforms are extremely important for strengthening the CEG, and it will eventually lead to effective and optimal WtE generation in the urban cities of the selected South Asian countries for green transition and urban sustainability. Finally, an integrated solid waste management framework has been formulated for policy implications in South Asia.

Summary: The world of bioplastics has rapidly expanded, generating new waste streams that pose challenges to waste processing; anaerobic co-digestion is considered the best option for efficient bioplastic waste processing with reduced space requirements and environmental pollution; the higher C/N ratio of bioplastics presents a challenge to anaerobic digestion, but co-digestion with lower C/N ratio biowastes can improve biogas production.

Summary: Municipal solid waste (MSW) management is crucial for reducing environmental pollution and greenhouse gas emissions. MSW-to-energy systems can provide a sustainable solution for waste management. This study aims to design an integrated energy system for converting MSW to hydrogen, utilizing gas turbine cycle, proton exchange membrane, and supercritical carbon dioxide Brayton cycle. The system is optimized using the Taguchi technique, producing power, hydrogen, oxygen, heated air, and heated water. The optimum conditions result in 472 kW of power, 57.7 g/min of hydrogen, 458 g/min of oxygen, 480 m3/min of heated air, and 12.2 L/min of heated water, with an efficiency of 79.3% and carbon dioxide emissions of 8.32 g/kW.min.

Summary: The study evaluates the current and alternative MSW paths in Mexico City to compare their performance in terms of fossil energy use, GHG emissions, resource recovery, and economic cost, aiming to identify more sustainable practices. The current MSW path in Mexico City is unsustainable due to heavy reliance on landfilling, large GHG emissions, and low MSW valorization, while incineration-based paths perform better in most aspects but are hindered by high costs. The results suggest that MSW paths featuring open windrow composting, mechanical-biological pretreatment, material recovery facilities, and refuse-derived fuel production may be more appropriate for improving the sustainability of MSW management in Mexico City.

Summary: Small-scale anaerobic digestion of wet organic waste can contribute positively to climate mitigation, energy security, and nutrient cycling. However, lack of capacity to utilize biogas fuel may lead to biomethane venting, contributing to climate change. Policy support in Bali, Indonesia has resulted in the installation of small anaerobic digesters, but insufficient means to convert the potential fuel into useful energy has led to wasted biomethane emissions.

Summary: The generation of municipal solid waste litter (MSWL) is a growing concern in urban areas, as it negatively affects the aesthetics and health of pedestrians and nearby residents. This study aims to assess the current status of MSWL generation and its management scheme in Nagpur, a tier two city in India. Characterization and environmental assessment were performed using the common weighted method for five different categories of streets. An environmental status index (ESI) model was developed to evaluate the existing scenario of MSWL management. The study found variations in MSWL generation rates among different types of streets, and the application of exploratory data analysis and cluster algorithm was effective in identifying areas with higher MSWL generation rates.

Summary: Wave energy technologies have great potential in the global supply of renewable energy, and fully submerged buoys are the most promising design for wave energy converters. This paper investigates the optimization of wave energy converter arrays consisting of three-tether buoys, aiming to optimize the total energy output by adjusting the relative positions of buoys in a wave farm. Solving this problem is challenging due to the complex hydrodynamic interactions among wave energy converters, but the proposed hybrid cooperative framework exhibits the best performance in terms of solution quality, computational efficiency, and convergence speed.

Summary: Urban energy system analysis requires setting the boundaries of the closed system, but the limits imposed by the Municipality do not capture the full extent of the energy supply. Expanding renewable energy installations can involve more territories and bring benefits to the local energy mix. The study shows that including surrounding areas can lead to more effective penetration of renewable energy and diversify investments, but it also comes with increased costs.

Summary: This research aims to minimize the impact of electric vehicle charging stations (EVCSs) in a radial distribution system (RDS) through the modeling and optimization of hydrogen-fuel-cell-based distributed generation (HFC-DG). The study addresses challenges such as increased power demand and voltage fluctuations by utilizing a novel spotted hyena optimizer algorithm (SHOA) to optimize the placement of HFC-DG units and EVCSs. The research also investigates the influence of HFC-DG and EVCSs on power system reliability. Optimized solutions obtained from the SHOA and other algorithms effectively reduce power loss and improve system reliability. This research highlights the potential benefits of integrating HFC-DG and EVCSs in terms of minimizing power loss, enhancing reliability, and optimizing distribution system operations.
