Vietnamese acacia wood pellets and Indonesia wood pellets are ideal for biomass power plants. Wood pellets are fuels that emit significantly less carbon dioxide, which causes global warming, than fossil fuels such as petroleum, and have been attracting attention in recent years as biomass with a low environmental load. Wood pellets, like fossil fuels, emit carbon dioxide when burned, which is the same amount that the wood material absorbs during photosynthesis during the growth process, resulting in zero deduction, so-called "carbon neutral". Our method allows for permanent supply while maintaining carbon neutrality by planting trees at the same time as logging. It is friendly to the global environment, helps the economies of developing countries while maintaining forests, and greatly contributes to world's stable power generation plans. In addition, it is possible to supply a large amount of wood chips for papermaking, which are 100% acacia and 100% eucalyptus, which are standard-compliant products for many companies.
