Abstract
This study explores the potential of harvesting and utilizing thermoelectric energy generated during biochar production. Biochar, a carbon-rich material produced from biomass pyrolysis, offers a sustainable pathway for waste management and soil improvement. However, the biochar production process also generates significant heat, much of which remains underutilized. This research investigates the integration of thermoelectric generators (TEGs) into biochar production equipment to convert waste heat into electricity. The system's design and optimization aim to enhance energy efficiency while supporting renewable energy goals, by using the harvested energy to power up small devices, such as sensors. Experimental results demonstrate the feasibility of capturing thermal energy and converting it into usable electrical power, contributing to the overall sustainability of the process. The findings also highlight key factors influencing thermoelectric conversion efficiency, including temperature gradients, TEG material properties, and system integration challenges. This approach not only mitigates energy losses but also aligns with global efforts toward carbon neutrality and resource optimization. The study underscores the dual benefit of biochar production: providing agricultural benefits while supporting energy sustainability.
