Summary: The growing volume of municipal solid waste (MSW) generated worldwide often undergoes open dumping, landfilling, or uncontrolled burning, releasing massive pollutants and pathogens into the soil, water, and air. On the other hand, MSW can be used as a valuable feedstock in biological and thermochemical conversion processes to produce bioenergy carriers, biofuels, and biochemicals in line with the United Nations' Sustainable Development Goals (SDGs). Valorizing MSW using advanced technologies is highly energy-intensive and chemical consuming.

Summary: This research examined the use of dry finely ground bottom ash (GBA) from municipal solid waste incineration as a supplementary cementitious material for concrete mixtures. The study found that GBA had both beneficial and detrimental effects on paste and mortar mixtures. It did not affect the water demand and workability of the mixtures, but resulted in a loss of mechanical strength in GBA mortar due to the presence of metallic aluminium and hydrogen gas evolution.

Summary: In this study, a unique solar-based waste to energy system that produces ammonia, electricity, and heating was developed and analyzed. Thermodynamic modeling and assessment studies were conducted to evaluate the system's performance using energy and exergy analysis methods. The system utilizes a solar tower to produce steam, which is then used as a gasification agent for plastic-based municipal solid waste to produce syngas. To reduce CO2 emissions, a CO2 capture system was integrated into the gasification system. Parametric studies were performed to improve the overall and subsystem energy and exergy efficiencies, and the Rankine and Brayton cycles were used to provide heat and electricity to the community.

Summary: In the current world energy scenario, renewable energy is crucial for reducing pollution from carbon-based fuels. Hydrogen is emerging as an important non-carbon-based energy source that can replace fossil fuels. This review paper discusses various aspects of hydrogen energy systems, including production, storage, and power generation. The main conclusions are that natural gas and coal supply most of the current hydrogen, with steam methane reforming, partial oxidation, and alkaline electrolysis being the commercially available technologies for production. Metallic cylindrical reservoirs and certain metal compounds have shown promise for large-scale compressed hydrogen storage. The transportation sector is expected to widely adopt hydrogen in the future, especially with fuel cells powering vehicles.

Summary: Polypropylene and municipal solid wastes (MSW) are significant environmental issues. Plasma gasification, due to its high temperatures, is an environmentally friendly method to decompose toxic compounds in plastic and MSW. A model was developed to investigate the feasibility of plasma co-gasification of MSW and polypropylene wastes, and a parametric study was conducted to analyze the effect of important parameters on syngas and hydrogen production. The results suggest that higher proportions of polyethylene in the waste mixture lead to higher molar fractions of hydrogen, and low air-to-waste ratios and equivalence ratios favor hydrogen generation. Steam and temperature have a minor effect on hydrogen production. These findings could promote plasma co-gasification as a new waste-to-energy management method.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.

Summary: This paper investigates China's energy trade stability using a survival analysis approach. It finds that the energy trade linkages between China and 153 other countries are complex and unstable, with short periods of trade with many countries. Geopolitically risky regions, such as the Middle East and Africa, have the lowest trade stability. Climate risks have significant effects on energy trade stability. The paper proposes several policy options to improve energy trade stability in China, with special attention to increasing global climate risks.

This study investigates the impact of REC purchases on stock return and volume in Taiwan between 2017 and 2021. The findings suggest that REC purchases have a positive effect on stock returns of manufacturing firms but not service firms. The frequency of REC purchases is also an important factor in the relationship between REC purchase and firm value. Additionally, the study reveals that public attention to environmental pollution plays a crucial role in positive stock returns and volume, while ESG disclosure is negatively associated with returns and volume.

Summary: This paper addresses the challenges of governing energy procurement from a mix of non-hydropower renewable energy sources supplied by independent producers. Building on political economy analysis and five case studies of independent producer projects from Ethiopia, it seeks to understand the root causes of the protracted delays and limited extent of procurement by independent producers. The key contestations lie in managing long term contracts, risk, uncertainty and in developing the institutional and human capacity to transition.
