| Abstract | Nowadays, the concerning on environmental problems is increasing. One of the main sources of environmental problem is emission from power plant. Thailand has many kind of power plant such as coal, water, wind and bio-fuels. This case study is mixed bio-fuels and coal power plant which located in Prachinburi province, Thailand. This study assessed the environmental impact potentials over the life cycle of 1 kWh of electricity produced by using cradle-to-gate life cycle assessment concept. The first step was to set the goal and scope definition. All data and necessary information were collected afterwards. The sources of data collection were both interviewing and observation throughout NPS power plant and deriving from literature and SimaPro database. After entering all data in SimaPro, the emissions were calculated. The calculation was performed based on Eco-Indicator99 (H) method. The obtained results showed that to produce 1 kWh of electricity, the environmental impact potentials were contributed at the amount of 0.038Pt.The highest contributor of producing electricity was coal combustion process. It contributed approximately 32% of total contribution. From sensitivity analysis, the results show that the parameter that effect to emissions are amount of coal used, transportation type, combustion value and overall efficiency. For amount of coal used, the less amount of coal used and more bio-fuels used are can reduce emissions. NPS can change transportation to used train for delivered coal from Lamchbang to power plant, the emissions are reduced by 14.6%. For combustion value changed, the lower combustion value are produced more emissions. The overall efficiency of NPS power plant is 31.6%. If it can increase to 45%, the emissions are reduced by 29.6%.The options to reduce emission form NPS power plant are decrease amount of coal and increased bio-fuel mixed, use high combustion value coal, increase power plant efficiency and improve transportation. |
