Synthesis and testing of CO2-capture materials made of coal or bagasse ash for CO2 mitigation in power plant – a case study of coal-fired power plant

Natural resource and environmental issues are growing and getting worse in the nation, with a focus on biodiversity management, sustainable consumption, and a low-carbon society. Today, it is crucial for the government, industry, and private sector to support and pay attention to the issue of decreasing the effects of pollution on the economy and society. Anthropogenic greenhouse gas emissions under the United Nations Framework Convention on Climate Change are based on a proactive international response to the SDGs and the aim to minimize greenhouse gas emissions from human activities. Thailand has contributed to the development of the nation in line with this strategy.

The creation of rules, regulations, and policies based on the bioeconomic model is one of the most obvious directives for the government. promote economic expansion while cutting greenhouse gas emissions and properly managing resources to get the most out of them Thailand likewise declared its ambition to become carbon neutral by 2050 and net zero by 2065 at COP26. Controlling global warming, becoming carbon neutral, and achieving a net zero greenhouse gas emissions would be challenging, according to the findings of an assessment of global greenhouse gas reduction activities by the UNFCC and several research institutes. Utilizing trapping technology and carbon capture, use, and storage (CCUS), which is one of the important steps, is necessary. CCUS technology is therefore receiving a lot of interest in the field of research today.

Therefore, the research question was developed based on the desired outcomes, namely "reducing greenhouse gas emissions in the industrial sector—focusing on the power and electricity generation sector" and "reducing industrial waste and increasing recycling rate." The main question is, "Can industrial waste be used to reduce greenhouse gas emissions?" and "To maximize the efficiency of the produced innovations. economically beneficial And how widely is it used in practice?" As a result, the project's research scope is to investigate the development of novel CO2 capture materials based on coal ash from power plant fuel combustion processes. Figure 1.1 depicts the project's objectives, goals, and indicators.

The operation is divided into four major steps to achieve the project's objectives: study, review of current data, research results, and implementation. We created and tested CO2 trapping materials in the lab. Figure 1.2 depicts the study of the potential of CCUS technology using trapping materials developed in the case plant and the public dissemination of the study's findings.

From its potential assessment, implementation of this project will provide academic, social, policy, and economic benefits. It was discovered that if there was a push for the use of CO2 trapping materials developed from this research project to be used in factories that burn coal fuel, it would result in a decrease in the amount of CO2 produced. This will allow us to reduce CO2 emissions by at least 29,253.62 tons per year, or 0.15% of the country's CO2 emissions from coal burning and municipal solid waste. As a result of this calculation, the amount of ash used to develop into a trapping material can reduce disposal and increase the rate of waste from the recycling process, accounting for 8.6% of the amount of industrial waste reported in the Department of Industrial Works system.
