Background
1991 : Biogas Advisory Unit (BAU) established under the Science and Technology Research and Development Centre CMU
2003 : Biogas Advisory Unit transformed to Biogas Technology Center (BTC) directly under Chiang Mai University Council
1988 : Thai-German Biogas Program (TG-BP) by Chiang Mai University + Dept of Agricultural Extension under support of GTZ initiated

Benefits from Biogas SystemBenefits from Biogas System
• Production Cost Reduction from replacement of conventional fuels with Biogas. Investment return period 3-8 years
• Effluent from system passes the discharge standard set by the Pollution Control Dept
• Reduce groundwater and surface water contamination and allow recycling of wastewater
• Reduce pollution problems in farm surroundings (Odor and Flies)
• Alleviate resistance from local community
