The biogas production from waste in school and the application of lunch project for student case study suksasongkhro tak school tak province

Abstract

This research aimed to transfer technology about biogas digester construction and applying the biogas in household to teachers and students in Suksasongkhro Tak school. They were instructed and trained about biogas digester construction and applying the biogas produced from animal manure on cooking in household to reduce using LPG. The research operations were separated to 4 phases. The first was preparation and making understanding. The second was instruction and practical training. The third was monitoring and project evaluation. The last one was organizing the science project event. The number of participant teachers and students was 330. From the result of 5 scale questionnaire in project evaluation, it was found that the evaluation about knowledge and understanding showed the maximum scale ( = 4.42, SD = 0.84). The second was about location, duration and food ( = 4.36, SD = 0.75). The evaluation about the knowledge showed the lowest scale ( = 4.28, SD = 0.77). For the project evaluation of success, it was found that every biogas digester done by participants could produce the biogas and it could be use to replace LPG and reduce expenditure about 1,400 – 1,500 baht/month. The total construction cost of biogas production system was 58,000 baht. So, the payback period was 3.22 years.
