Case Studies: Green Power from Pig Farms, Thailand

Further information

This project activity involves the installation of a system to treat pig barn-flushing water. The system is treating the wastewater in an anaerobic process, which will generate biogas, and this gas will serve as fuel for heat and/or power generation.

The CDM activity includes the installation of the wastewater treatment systems at three pig farms in the Ratchaburi Province of Thailand. All three farms have invested in a closed anaerobic treatment reactor to treat the barn-flushing effluents produced from their pig rearing operations. At all three farms the new systems will replace traditional open lagoon treatment systems.

In the previous open lagoon system, the produced biogas was emitted directly into the atmosphere. However, in the new closed system, most of the gas is collected and combusted for the production of electricity for use on-site (and in one case using a cogeneration/boiler system to generate electricity and steam). This power replaces electricity previously brought in from the Thai electricity grid.

The technology applied in the treatment of the wastewater is called an Upflow Anaerobic Sludge Blanket or UASB.
