SioTeX has developed a proven, patented, proprietary process to extract high purity silica from rice hulls. Rice hulls are an abundant bio-waste produced from the rice milling industry. The hulls are typically land filled or open field burned, which harms air quality. Our process turns this bio-waste into a high quality, eco-friendly soil amendment; Grow-Sil. Our process doesn't produce any toxic reactants and is energy efficient. The EPA has recognized SioTeX with a People, Prosperity and Plant (P3) award. We have also been awarded an EPA Phase 1 and Phase 2 Small Business Innovation Research (SBIR) grant for industrial process pollution reduction. Additionally, SioTeX won first prize in the 2014 American Chemical Society's Green Business Plan competition.
