The National Nanotechnology Center (NANOTEC) under the National Science and Technology Development Agency (NSTDA) is advancing research and development of “Biochar,” a carbon-based material derived from agricultural biomass. The innovation aims to convert agricultural residues into high-value, renewable carbon materials with diverse applications in energy production, agriculture, water treatment, and green construction.The initiative supports Thailand’s goals for energy security and environmental sustainability through the integration of nanotechnology, materials science, and environmental engineering.
NANOTEC has developed a thermal reactor system using Dry Torrefaction and Pyrolysis technologies, which process biomass at 300–600°C under low-oxygen conditions. This method produces high-quality biochar with low moisture, high carbon content, and high heating value. The pilot system can generate 300 kilograms of biochar from one ton of biomass and has been tested in collaboration with energy sector partners for semi-industrial applications.The technology offers potential as an alternative energy source for biomass and coal-fired power plants while supporting Thailand’s transition toward low-carbon energy systems.
Beyond its role in energy, biochar is being utilized as a soil enhancer, a carbon capture material, and a component in sustainable building materials. Bypromoting biochar innovation, NANOTEC aims to establish a “green value chain” linking farmers, industries, and government agencies. The initiative contributes to Thailand’s path toward carbon neutrality, demonstrating how science and technology can drive responsible and sustainable national development.
