SwissX Island has published independent laboratory results for a new carbonized supercompost produced from sargassum seaweed and organic waste in Antigua. The soil amendment contains 38% fixed carbon and high potassium levels, making it a viable tool for regenerative farming and water retention in tropical climates. The company is positioning the biochar as a carbon-credit-ready product. By integrating this material into agricultural systems, growers in the Caribbean may be able to access sustainable farming incentives and participate in emerging agricultural carbon markets.
