We own and operate five Anaerobic Digester wastewater plants across Central and North Vietnam. These facilities treat wastewater from plants processing cassava roots and by doing so, both avoid methane emissions and supply renewable energy.

4,500,000 m³ per year
tCO₂ of carbon reduced every year
m³ of methane destroyed every month
m³ of wastewater treated per year
Delivering positive impacts aligned with UN Sustainable Development Goals
Worldwide, the pressure to become more efficient has driven agricultural operations to become progressively more intensive to realize the economies of production and scale. This is especially true in the starch processing industry, where wastewater is the main source of pollution to the surrounding environment and water sources.
Anerobic Digester plants capture and destroy methane emmisions
The project activities involve the implementation of a two-stage wastewater treatment system. The first stage of the treatment recovers methane caused by the decay of biogenic matter in the effluent stream by introducing a sequential stage of wastewater treatment with methane recovery. By extracting the biogas, the project activity reduces methane emissions that would have otherwise been emitted. The second stage utilizes the biogas generated by the first stage to provide a reliable and low-cost energy source to operate the starch factory, replacing the use of intensive fossil fuels such as coal.
The projects prevent an estimated 60,000 tCO₂ each per year from being emitted into the atmosphere, thereby preventing pollution in water sources, improving air quality, reducing odour, recovering energy and protecting the environment.
Demonstrating the Importance of Carbon Revenue
The project activity is classified as a ‘vulnerable’ project type due to its ongoing financial need. The reliance upon carbon revenue is demonstrated by continuous issuances. Without carbon revenues, the project would cease operations due to high operating costs and lack of technical capacity.
