“…In many underdeveloped countries, the use of raw biomass as an energy source has a negative impact on health and the environment [20]. However, as urbanization advances, waste from these sources may not be disposed of responsibly [21]. At worst, this waste is burned inefficiently, contributing to air pollution [22]; however, if handled well, and depending on the waste, they could be sources of renewable energy.…”

Nigeria has the potential to generate 12,522 MW of electricity, but can only dispatch 4000 MW, which is insufficient for a population of over 200 million people as of 2022. Therefore, Nigerians use solid fuels including firewood and charcoal as an alternative to insufficient electricity for domestic use. The consumption of firewood and charcoal in Nigeria is estimated at 23,745,458 tons and 4,828,689 tons, respectively in 2021, by far the most consumed domestic solid fuel sources in Nigeria. Although there are domestic solid fuel alternatives, such as dung, agricultural residues and coal, to firewood and wood charcoal, their sustainable adoption has been slow in Nigeria, indicating that there is insufficient knowledge of domestic solid fuel sources. This requires a review focused on assessing Nigeria’s national sources of solid fuels. This article presents an overview of the sources of domestic solid fuels in Nigeria, an exploration of different types of firewood and charcoal studies, the impact of solid fuels on climate change and the environment, health risks associated with solid fuel and biomass briquettes and pellets as domestic solid fuel alternatives to charcoal and firewood. The continued production and use of firewood and wood charcoal as domestic solid fuel sources encourage deforestation, desertification and greenhouse gas emission, which in turn pose a threat to a sustainable environment and good health. It is necessary to limit the felling of trees for firewood and charcoal production to curtail their negative impacts on the health of users and the environment. This review covered the thermal, mechanical and physical properties of briquette and pellet fuels as substitutions for firewood and charcoal. It was shown that employing briquettes and pellets as a source of solid fuel in the home will lessen the negative impacts that these fuels have on users’ health, the climate and the environment.

“…Zhu et al, 2021). The potential for water, wind, and solar energy in this region is projected to reach 54.5 GW, 430 GW, and 510 GW respectively (Asmare, 2019), although only a small portion is currently being exploited. For example, the potential for hydropower in Russia reaches 1.67 TW per year, but only less than 10% is utilized.…”

In recent decades, sustainable economic growth has caused an increase in energy consumption in North Asia, especially in China, Japan and South Korea. However, internal supply cannot meet energy demand, bringing two related consequences: First, the enlargement of the gap between production and consumption leads to dependence on external energy sources. Second, forcing the government to map its energy policy. However, unlike other regions such as the European Union and the Association of Southeast Asian nations, the dependence of the Energy of Northeast Asia has not caused the closest intra-regional cooperation. Conversely, in some cases, it damages cooperation and worsens non -constructive competition. Therefore, in this study, we aim to highlight the problematic relationship between energy securitization and regional energy cooperation in Northeast Asia and provide an analysis of the reasons, mechanisms and challenges for regional cooperation led by energy. In this case, we think that, by exploiting regional compatibility in the generation of renewable energy and in the consumer model, building a mechanism of integration and multimodal communication will promote greater integration and contribute to filling the gap between securitization and energy cooperation in the east and work the same in the east and working with Asia.

“…As shown in table 1 below, solid waste production is rising in all waste generation sources. Depending on the result and from the total waste generated, only 58% was properly collected and disposed of and 86% of the total waste generated is degradable (Asmare & Alelign, 2019;Wegedie, 2018)…”

“…applied the wastes produced from one sector to as an input for another one). There are several studies that can be used as inputs to convert Bahir Dar's policy from a linear to a circular economy system (Asmare & Alelign, 2019;Biruk, 2017). According to (Asmare & Alelign, 2019), more than 74 percent of Bahir Dar City's municipal solid waste can be used to make briquettes, and over 86 percent of the waste can be composted into organic fertilizer.…”

The generation of MSW in urban areas in Ethiopia and elsewhere continues to increase and poses a challenge to city governments and citizens if the wastes are not properly managed. Applying an integrated system for managing MSW and recovering the material for use in new products can reduce the negative impacts on the environment. The purpose of this study is to apply the DPSIRO framework to develop a system that reduces the negative impacts of MSW in Bahir Dar city in a sustainable way. The research started by identifying the main driving forces that lead to the generation of MSW. Then, states because of pressures and the consequent impacts were investigated. Finally, the appropriate responses and outcomes obtained from the responses were dealt with. Methods used to quantify GHG emissions, leachate, and eutrophication potential were applied. According to the findings, the waste disposal site emits an estimated 46Gg of greenhouse gases per year in 2020.The eutrophication capacity of organic waste generated in the city was 0.0594 Kg N-equivalent or 59.4g N-equivalent. The waste also contains an average of 1,112mm of leachate per day on an annual basis. The state of the environment has an impact on human health and the ecosystem. Applying the circular economic system, knowledge transfer, and waste management fees are the main responses suggested to decision and policy makers. The responses correspond with balanced economic, social and environmental situations. Outcomes were quantified in terms of organic fertilizer, income and renewable energy (briquette) when the actions were taken.
