Trends and Prospects of Sediment Microbial Fuel Cells as Sustainable Aquatic Ecosystem Remediation Technology

Korea consumes a large amount of energy. Korea is vulnerable to energy security due to its high dependence on energy imports. The amount of waste generated in South Korea is increasing every year. Recycling accounted for the highest proportion of waste disposal methods at 86.6%, but this was calculated based on the amount brought into recycling facilities. In fact, large amounts of waste are landfilled or incinerated. Landfilling and incineration of waste causes various environmental pollution problems. We need innovative and practical technologies that convert waste into energy and have less impact on the environment. Waste gasification technology is currently attracting attention because it emits less pollutants and can produce energy using waste as a raw material. In this review, we briefly summarized the principles and characteristics of the gasification process, and discussed the current status and limitations of waste gasification process equipment in Japan and overseas, and the direction that should be taken from the technical and institutional aspects.

Solar Photovoltaic Industry in Korea: Current Status and Perspectives

et al. 2023

Globally, interest in renewable energy and related industries are rapidly increasing in recent years. In solar power generation, almost unlimited energy resources can be supplied as long as the sun does not disappear, and carbon dioxide is not generated when looking at the power generation process itself. However, photovoltaic power generation faces several fundamental problems such as low economic feasibility, disposal of waste panels, environmental destruction due to installation, and generation of harmful substances in the production process. In this review, the current status of photovoltaic power generation is reviewed and, based on this, the direction for Korea's photovoltaic policy is suggested. 1) In order to overcome low economic feasibility, large-scale power generation projects should be promoted to achieve economies of scale. 2) Existing buildings or spaces must be utilized to prevent forest damage from photovoltaic power generation. 3) Active support and investment from the state and companies are needed to develop eco-friendly technologies for reducing hazardous substances and recycling waste panels. 4) An institutional system for information disclosure and management of harmful substances for solar energy projects should be established.

“…2) 기후변화의 위기감이 고조됨에 따라 세계적으로 탄소 배출을 하지 않는 에너지원에 대한 수요가 증가하고 있 으며, 환경에너지 분야에서도 탄소 배출 감축에 부응하기 위 한 다양한 시도가 이뤄지고 있다. [3][4][5][6][7][8][9][10][11][12][13][14] 정부 뿐 만 아니라 기업에서도 기후변화 대응을 위한 많은 노력을 기울이고 있다. 기업은 ESG경영을 통해 친환경적 기 업 운영을 강조하고 있으며, 기업 경영의 지속가능성과 책임 투자의 지표로 활용되는 디우존스 지속가능경영지수(DJSI)는 기존의 경제적 결과에서 ESG 경영의 성과를 추가하여 종합적 인 평가를 내리고 있다.…”

et al. 2023

The world is gripped with a sense of crisis over the disasters caused by rapid climate change. Various policy and technical attempts are being made to reduce carbon emissions around the world. Since the issue of RE100 was raised in the last presidential debate, interest in RE100 has been increasing. RE100 is a voluntary campaign to cover corporate power with 100% renewable electricity, and is attracting more attention in line with the company's sustainable management policy. In this review, the reality of RE100 and related policies were investigated. Based on this, the institutional direction for the realization of RE100 was presented.
