Thai Wah Biogas


In 2002, Asia Biogas built the first large-scale ‘Build Own Operate Transfer’ biogas plant in the cassava starch industry.  The Korat Waste to Energy project was expanded to treat solid waste from cassava starch and to sell both thermal energy and power.  We are proud our role in making biogas the top thermal energy choice for Thailand’s cassava starch industry. 

Our group has invested in a further ten [CWTE, Kalasin, LIG, SWTE, JIR, KIT, TCP1, TCP2, CWP, CKA ] BOOT biogas projects in Thailand and Lao PDR, mostly in the cassava starch and palm oil sectors.  Altogether four of our BOOT projects [korat, kalasin, cwte, cka] have been successfully transferred back to the host factory. 

We developed and built 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.

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 completed in December 2018 in Rayong, Thailand with support from the Department of Energy Efficiency and Alternative Energy. 

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 Thailand’s natural gas pipeline network thereby reducing the demand for LNG imports.

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 from waste water ponds.  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 could produce about 4.5 billion Nm3 of biomethane, roughly equivalent to 15% 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.
