Municipal solid waste management is an important issue in Thailand as most of the municipal solid waste (MSW) generated is managed inappropriately. Some are left uncollected in the residential areas, while some end up in open dumps, causing environmental problems. Alongside the problem of overdependence on coal as a fuel in the energy sector in Thailand and its greenhouse gas emission problem from the combustion, converting MSW to coal alternative fuel to be used in existing coal-fired power can improve both the situation of waste management and energy supply. Hydrothermal carbonization (HTC), a pretreatment technology that can converts MSW to a homogenized coal-like fuel with increased heating value, is an attractive technology. The purpose of this research is to estimate the atmospheric pollutant emission from the substitution of coal to MSW-derived fuel from hydrothermal carbonization in a coal-fired power plant in Thailand. The result shows that CO2, SO2, and CH4 emissions decreased with the increase of substitution of lignite with MSW-derived fuel. In the scenario where all collected MSW in the Northern region is used as a substitution for coal, the CO2, SOx, and CH4 emissions were reduced by 5.43%, 18.71%, and 28.52% compared to the baseline scenario respectively.
