800,000 tonnes of CO2 emissions reduced per year, equivalent to the emissions of 370,000 people


200 GWh clean energy produced, enough to supply 250,000 people with clean and reliable energy


100,000 tonnes of wastewater treated per year, equal to domestic wastewater produced by 5 million population equivalent 



In the absence of oxygen, microorganisms break down organic matter and clean troublesome wastewater by producing biogas - a highly valuable hydrocarbon. This wastewater treatment technology through anaerobic digestion was first developed in the 30s. Due to pressure from environmental-related legislation, it became a mainstream option in developed countries. Since early 2000s, it has become a proven and well-established technology for energy generation. Biogas electricity generation has increased dramatically in European Union countries reaching 62.5 TWh in 2016, around a quarter of the electricity consumed in Indonesia that year.
