Biogas energy Thailand
The wastewater treatment facility provides the starch plant with clean energy from biogas.
All across Thailand cassava is used for starch production. During the cleaning and processing large amounts of wastewater are produced. This wastewater is very rich in organic matters that generate methane, a greenhouse gas 21 times stronger than CO2.
In the plant where the project was implemented the daily amount of wastewater is approximately 5,000 m3.The warm climate of the region and the fact that the average temperature in the lagoons is between 25 and 35 degree Celsius result in an anaerobic environment in the ponds, which is the source of the generated methane.
Besides eliminating the release of methane, the fact that the biogas is replacing fossil fuels is an additional benefit. The treated water is recycled for use in the plant and not released into any surface water body, which makes it possible to keep fish in the surrounding lakes and use the water for irrigation. show all
The installed biogas generating wastewater treatment plant is able to convert more than 95% of organic matter in wastewater to 40,000 m3 of biogas daily. This biogas can be used to replace 24,000 liters of oil.
The emission reduction due to the project activity during a given year is calculated as the difference between baseline emissions (in a business-as-usual scenario), project emissions and emissions due to leakage.
Nakhon Ratchasima (also known as Khorat) is traditionally an agricultural province where most of the population works in farming, cultivating crops like rice, sugar cane or tapioca. Most of the factories are rice mills and tapioca product manufacturers.
The region is more popular among Thai rather than foreign tourists even though it has a number of attractions to offer. Among others the largest sandstone sanctuary in the country, Prasat Hin Phimai or Thailand’s first national park, the Khao Yai National Park, which besides its 200 wild elephants, also houses tigers, gibbons, bears and hornbills.
Since Khorat used to be a former US airbase during the Vietnam War, there is quite a significant number of war veteran retirees in the area.
