Project:
Biogas Extraction from Wastewater in Thailand
Cost P/Tonne: £8.43
Biogas is extracted from wastewater using UASB reactor before the wastewater goes to open lagoon. Biogas is then used in boilers to replace fossil fuels and provides electricity for the surrounding areas. In reducing the amount of fossil fuels burnt to produce power, the project directly reduces green house gasses.
The project replaces odorous lagoon systems and creates effluent that meets all environmental standards. In replacing fossil fuels the project improves the trade balance of the country. Also by increasing the profitability of the plant, prices for tapioca can increase, benefiting a large community of poor small-scale farmers. Introduction of cleaner technologies leading to popularization of the technology in the region & country means that the surrounding areas will follow by example and reduce their own reliance on fossil fuels. Improved employment to lower economic sector is also a benefit resulting from the project.
Project Contribution to sustainability:
1. Social well being:
The project contributes to the development of the region.
During civil works, a lot of construction work took place, which generated employment for local people around the plant site.
Operation and maintenance of the Biogas extraction plant generates employment opportunities on a regular and permanent basis.
2. Economic well being:
The project activity generates employment in the local area.
The project activity has lead to investments in a developing region which would not have happened in the absence of project activity.
The generated electricity is fed into the regional grid, thereby improving the grid stability and availability of electricity to local consumers (villagers & sub-urban habitants) which will provide new opportunities for industries and economic activities to be setup in the area, thereby resulting in greater local employment, ultimately leading to overall development.
In recent years, Thailand has witnessed an increase in power consumption. Both public and private parties are struggling to meet the demand for electricity. The Biogas extraction project will contribute in a sustainable manner to bridging the gap between supply and demand of power on a regional and national level.
The project activity has also led to diversification of the national energy supply, which is dominated by fossil fuel (mainly coal) based generating units.
3. Environmental well being:
Use of a renewable energy sources helps the conservation of natural resources in the country. In Thailand, the lion share of total electricity production is derived from coal based power plants. Being so heavily dependant on coal for its energy requirements, this project, in addition to its inherent contribution to climate change mitigation, carries environmental benefits for the country’s air, soil and water resources. The project increases the share of renewable energy generation in Thailand, making a contribution to avoid the construction of new fossil fuel fired power plants. As compared to these power plants, the project reduces CO2, SOx and NOx emissions significantly, thus mitigating air pollution and its adverse impacts on human health.
