Rivertop has developed a novel sugar acid platform using their proprietary oxidation technology to produce glucaric acid and other chemicals from renewable feedstocks like sugars. Their one-pot process results in significantly lower production costs than conventional methods. They have demonstrated the scalability of the process and are constructing their first commercial plant. Rivertop aims to become the low-cost supplier of glucaric acid and establish it as an industry standard chemical by leveraging their cost advantage, technical performance, and versatility across multiple end markets like detergents, corrosion inhibition, and more.
