SET-listed BBGI, the biotechnology arm of Bangchak Corporation, is accelerating efforts to make bio-liquefied natural gas (bio-LNG) a mainstream alternative fuel for Thailand's industry and transport sectors as rising global LNG prices driven by the war in Iran pressure domestic energy costs.Daechapon Lersuwanaroj, chief executive and president of BBGI, said energy authorities believe domestic sales of bio-LNG are feasible.

A public hearing on the issue is underway and officials are reviewing regulations for production and sales within this year.

"Bio-LNG will not face price fluctuations like imported LNG when a war breaks out," he said, pointing to the stability bio-LNG could bring to Thailand's energy mix.

Bio-LNG, also known as liquefied biomethane, is produced from biogas through anaerobic digestion. Biogas contains methane, a greenhouse gas, which derives from wastewater and solid waste. By capturing this methane and converting it into bio-LNG, BBGI aims to prevent harmful emissions while creating a renewable substitute for fossil fuel-derived LNG and diesel.
