Biogas situation and development in thai swine farm

Abstract

The biogas technology in Thailand has been developed and adopted for many years, especially in the swine farm industry. The objectives of the biogas development are based on three main problems; i.e. (i) to reduce the appalling odor, (ii) to treat the wastewater, (iii) and to produce the biogas which is known as a renewable energy sources from the anaerobic digestion wastewater treatment processes. In this paper, the biogas situation including the technology development for swine farm in Thailand, which are mainly used the upflow anaerobic sludge blanket (UASB) bioreactor system, was discussed. From the results, we found that 11.6 million cubic meters of biogas per year would be produced under the government subsidization projects which gas then be used for various proposes; e.g. electricity generation, LPG or fuel oil substitution in boiler and heating system.
