"The billions of microbes in our anaerobic digesters are the worker bees of the circular economy working 24/7 to convert organic waste to biomethane."

BUILD OWN OPERATE
In 2002, Asia Biogas built the first ‘Build Own Operate Transfer’ biogas plant in the cassava starch industry to turn waste water into clean thermal energy. The Korat Waste to Energy project was expanded to treat solid waste and excess biogas was used to generate electricity. We are proud of our role in making biogas the top thermal energy choice for Thailand’s cassava starch industry where 73% of factories now use biogas produced from their own waste.
Our group has developed and completed a further 12 BOOT biogas projects in Thailand and Lao PDR, mostly in the cassava starch and palm oil sectors. Altogether seven of our BOOT projects have been transferred back to the host factory.
We also developed more than 40 small-scale biogas projects at livestock farms in Philippines. And we developed the first BOOT biogas project at a dairy farm in Indonesia.
Some key figures
In 2019, we produced some 30 million Nm3 of biogas at our waste to energy plants. Total installed capacity is 20 MW.
We employed some 92 staff, mostly in rural communities. A majority have tertiary level qualifications.
We treated 2.5 million tons of very high Chemical Oxygen Demand wastewater — that is 6,900 cubic metres or about 3 Olympic-sized swimming pools every day.
We created about 300,000 tCO2 equivalent per annum in emission reductions which is about the amount created by a solar power project with capacity of 250 MW.
COMPRESSED BIOMETHANE GAS
In Thailand our focus is to expand production of biogas from palm oil mill waste and cassava starch factory waste. Our first Compressed Biomethane Gas project was commissioned in June 2019 in Rayong, Thailand with support from the Department of Alternative Energy Development and Efficiency (DEDE).
We are now licensed to sell CBG as transport fuel, a direct replacement for compressed natural gas vehicle fuel known as ‘NGV’. The future for biogas in Thailand is biomethane – a clean, renewable fuel that is 100% Thai. It will be sold to NGV customers through existing NGV fuel stations or to industrial buyers. In future we look forward to selling 100% Thai biomethane into PTT’s natural gas pipeline network thereby reducing the demand for LNG imports.
INDONESIA PALM OIL BIOGAS CLUSTER PROJECT
In Indonesia our focus is to develop biogas systems at palm oil mills. We aim to deliver waste treatment solutions and produce clean energy by capturing climate-heating methane emissions. Our vision is to make biogas the first choice source of clean energy for Indonesia’s palm oil industry, the world’s largest, just as we did for Thailand’s cassava starch industry.
Asia Biogas estimates that anaerobic digestion of palm oil industry waste in Indonesia can produce about 5 billion Nm3 of biomethane, equivalent to 13% of the country’s natural gas consumption. We are working on the first cluster in East Kalimantan. With the support of environmentally-conscious investors, carbon offset buyers and the Indonesian government we aim to bring positive change to the palm oil industry.
