Thermochemical conversion is a process that transforms organic materials, such as biomass, into energy-rich fuels or chemicals using heat. This method typically involves high temperatures and can include techniques like combustion, gasification, and pyrolysis. The heat breaks down the material, releasing energy in the form of gases, liquids, or solid residues. This conversion process is significant for producing renewable energy and reducing waste. By converting materials like agricultural residues or municipal solid waste, thermochemical conversion can help decrease reliance on fossil fuels and lower greenhouse gas emissions, contributing to a more sustainable energy future.
