Overview of Biogas Production Potential from Industry Sector to Produce Compressed Bio-methane Gas in Thailand

摘要

Thailand's final energy consumption has increased continuously. The government policies used to up more alternative energy consumption in all sectors; especially the agroindustry wastes which the most of the wastewater from the production and has the potential to produce biogas. Currently, Thailand has over 1,700 biogas plants and over 150 plants of industrial waste which joined the biogas promotion project for industry supported by Energy Conservation Fund, Ministry of Energy. The projects of Thai government have been applied biogas to produce Compressed Bio-methane Gas (CBG) which for Natural Gas for Vehicles (NGV) and to replace liquefied petroleum gas (LPG) for use in industrial ceramic kilns. Biogas is an important raw material in the production of CBG. It can be used as renewable fuel in the production and transportation. So, this article presents an overview of biogas production potential from agroindustry in Thailand. The selection from 5 types of agriculture industry which was organic waste; ethanol, rubber, cassava starch, palm oil and food processing industry for the years 2008-2015. This research using secondary data of yield and wastewater quantity for a calculation to the potential of CBG production. The results show that the agroindustry has the most of CBG production potential were cassava starch, ethanol, rubber and food processing industry respectively and increasing trend.
