More about biogas
Biogas is produced when organic materials like food waste, waste water, plant waste and animal waste are broken down by bacteria in an oxygen-free environment through a process called anaerobic digestion. Through anaerobic digestion these biogas systems recycle the organic materials biogas. The captured biogas can be utilised to produce heat and electricity for use in fuel cells, engines or microturbines.
By refining biogas further (removing carbon dioxide) it can be converted into biomethane which is a renewable natural gas or RNG which can be injected into gas grids or produce electricity. It can also be used as vehicle fuel which converted into compresses natural gas.

Project information
This biogas project at SPM Farm is located at Pak Thor District, Ratchaburi Province, Thailand. The project consists of a high-rate continuous flow closed anaerobic treatment reactor to treat the barn flushing effluents produced by SPM’s swine rearing operations.
The system is equipped with a biogas capturing system and it replaced the low-rate open anaerobic lagoon barn flushing effluent treatment system. The captured biogas is used as fuel in two units of gas engines to generate electricity for using in the farm. The generated electricity displaced the power that was previously imported from the national electricity grid. This project results in the reduction of GHG emissions through avoidance of methane from the conventional open lagoon system and displacement of electricity from the national grid.
Furthermore, our host site and CDM project possess the required necessary environmental, health & safety and social (EHS) permits and are in compliance with EHS permit condition. There is no social unrest or negative campaign by affected communities or NGOs involving either the host site or the CDM project in relation to the lives or health & safety of workers and affected communities and the integrity of the local environment.

Sustainable Development Goals
As a Paying.Green® member, your investment not only benefits the environment, but it also supports communities through the United Nations Sustainable Development Goals.
Enhancing the nutritional intake of local children through the free distribution of a portion of the dried sludge to local schools for use as fertiliser for a local student food program.
The surrounding communities will experience a significant reduction in the odour and fly nuisance that was associated with the previous open lagoon treatment system.
Elimination of the fossil-derived importation of grid electricity for use in the swine rearing facility, and access to low cost power for swine producers.
The project will reduce the GHG emissions associated with the previous open anaerobic lagoon treatment system. The project results in annual estimated reduction in emissions of 327,563 MT CO2-e.
