The appropriateness assessment of rice husk power generation technology : case study of the Chai Nart power plant
Abstract:
The purpose of this study is to evaluate the appropriate technology in term of environmental impact, commercial viability and public participation of The Chai Nart Power Plant in the approach to improving Rice Husk Power Plant for investor, authority, and people. Using the collecting and questionnaire method, the environmental study was compared by the environmental standard of Thailand, the commercial viability study was compared by the investment criterion and sensitivity analysis, and the data of public participation was analyzed by the statistics are frequency, percent, standard division, maximum, minimum, Analysis of
Covariance (ANCOVA), and Multiple Classification Analysis (MCA). The method of appropriateness assessment of technology is Delphi technique. The results found that the environmental management meets the standard as dust quantity in 24 Hr at 0.228 mg/m3, noise level in the plant at 67.4 dB (A) and noise level in
community at 48.6 dB (A), and the pH summation at 7.99. As for the commercial viability analysis, for 20 years, the plant will break even by Net Present Value at 269,709,698.64 baht, Internal Rate of Return at 12 percent, Benefit/Cost Ratio at 1.5, and Pay Back Period at 7.58 years. However, the result of sensitivity analysis demonstrated that if the price of rice husk increases to 700 baht/ton the plant will not break even. As for the public participation, it demonstrated that most of samples are male, between 40-49 years old, average 45.89 years old, farmer, graduated in primary school, 40- 49 years residence, gain average income 6,001-8,000 baht/month. The affected people equal 94 percent, and affected people at a low level equal 37.1 percent. Thus, people participated at a low level and willingness for public participation was at a moderate level because the impact is not much more harmful, but it is a prolonged problem. Therefore, the impact is an important factor of public participation; education and impact are related factors of willingness for public participation. As for the
appropriateness assessment of technology, the Chai Nart Power Plant technology is appropriate but it is less of public participation. Therefore, the recommendation of this study is the plant should install air bag filter, arrange a meeting and the trilateral commission to follow and solve the problem, including paying compensation to farmers who have been affected
