Enhancing carbon reduction and sustainable agriculture in Thailand: An assessment of rice straw utilization strategies
Year: 2024
Type: article
Abstract: This research explores strategies for carbon reduction through the utilization of rice straw waste in Thailand, focusing on three project approaches: (1) converting rice straw into biomass fuel pellets for power plants, (2) transforming rice straw into biochar using high-tech systems and blending it with fertilizers, and (3) using conventional systems for biochar production . The study assesses the greenhouse gas (GHG) reduction potential of these approaches compared to traditional open-field burning of rice straw. The results indicate that Project 2, which involves high-tech biochar production, exhibits the highest potential for GHG reduction and carbon sequestration , with a potential to reduce emissions by approximately 12.19–13.05 MTCO 2 e /year. This approach also has potential for generating valuable carbon credits due to biochar’s long-term carbon sequestration and soil enhancement benefits. In contrast, Project 1 yields a reduction of about 4.06–4.35 MTCO 2 e /year, while Project 3 results in negative emission reduction. The study recommends prioritizing and incentivizing biochar production projects, upgrading low-tech systems, balancing the use of biomass fuel pellets, leveraging carbon credits for funding, and enhancing public awareness.
