Blue Fire Biogas

Creating sustainable energy from wastewater


Imagine if your home, village and workplace was permeated with a bad smell that never went away, one that not only caused discomfort, but was also permanently damaging the environment. For the inhabitants of the Nakhon Ratchasima area in North Eastern Thailand, this used to be a reality. Methane, which is a greenhouse gas 21 times stronger than CO2, has a strong unpleasant smell and was being steadily released into the atmosphere from open wastewater lagoons at the local starch factory.

Sustainable Development Goals

3. Good Health and Well-Being

2 public health centres

supported, ensuring access to better health facilities for the area

4. Quality Education

30 jobs

created permanently for local workers, providing stable income streams for the local economy

7. Affordable and Clean Energy

3,500 MWh

of clean energy generated a year, providing a cleaner alternative to the burning of fossil fuels

13. Climate Action

30,000 tonnes of CO2e

mitigated annually by capturing methane emissions and displacing fossil fuel energy

The Solution

This project involves converting the open lagoons system into two closed anaerobic wastewater treatment facilities (Upflow Anaerobic Sludge Blanket technology) that capture these methane emissions and use them for clean energy production on the plant site.


The Impact

Today, thanks to the Blue Fire Biogas project, the environment and quality of life in the area has vastly improved. Now, the harmful odor has been vastly reduced, and the quality of the wastewater is much cleaner. Because the plant is less reliant on the purchase of fossil fuels, excess revenue has generated more jobs as well as health and educational support in the local community.
