New Sustainable Food and Agriculture Study Results Reported from Guangdong Academy of Science (Integration With Carbon Capture Technology Enables a Positive Carbon Balance for Sustainable Rice Paddy Remediation With Calcium-silicon Composites).

A new report discusses research findings on sustainability in food and agriculture, specifically focusing on the remediation of Cd-contaminated paddy soils using lime-derived materials. The study evaluates the effectiveness and environmental sustainability of two lime-derived materials, quicklime and calcium-silicon composite (Ca/Si), in reducing Cd bioavailability and enabling the safe use of rice grain. The research concludes that both materials can be effective, but the Ca/Si case has a lower negative impact on the environment and exhibits outward carbon emissions throughout its life cycle. The implementation of carbon capture technology with Ca/Si can achieve a positive carbon budget and contribute to a carbon neutrality plan. Overall, the study provides valuable insights into the environmental sustainability of different lime-derived materials for paddy soil remediation and carbon mitigation. [Extracted from the article]
