Smothong Group Public Company Limited and its subsidiaries (“the Group” or “SMO”) engage in the business of producing and distributing electricity from biogas. This is another business segment related to the crude palm oil production and distribution business. By taking wastewater from the production process, mixing it with decanter cake, and fermenting it in biogas fermentation ponds, biogas is produced to be used as fuel for generating electricity for sale to the Provincial Electricity Authority (PEA). The Group's renewable energy business manages waste under the concept of using renewable energy that can be restored or regenerated, while reducing production process waste to zero (Zero Waste). This creates a positive environment for the community and generates maximum benefit for the Group by taking certain by-products and using process water with high Chemical Oxygen Demand (COD) through a decomposition process using microorganisms in an anaerobic environment under appropriate temperature and humidity to produce biogas for use as fuel in electricity generation.
