The integration of bioenergy and natural carbon sinks is of significant importance, as it addresses two urgent challenges we face today: climate change and resource depletion. Therefore, this research aims to utilize nature-based solutions to develop technologies related to biomass energy carbon capture and storage (BECCS) in the agricultural sector, further enhancing the potential of natural carbon sinks.

This study develops an advanced, efficient biological sequestration technology that combines biochar and compost into the formulation of soil carbon sink agents, which are then verified through a measurement, reporting, and verification (MRV) system as recommended by international standards. Additionally, a comprehensive life cycle assessment model for natural carbon sinks is developed, including plant absorption, soil carbon sequestration, and water storage carbon, necessitating the monitoring of organic carbon in environmental media. Finally, strategies advocating for "natural carbon sinks" based on performance indicators considering engineering, economic, and environmental aspects are proposed.
