Rivertop has developed a novel sugar acid platform to produce chemicals from renewable feedstocks. Their first product is glucaric acid, which they are commercializing. They have raised $26 million in funding and are building their first commercial plant with 8 million pound annual capacity. Their technology offers lower costs than conventional methods. They plan to expand production capacity and apply their platform to additional markets like detergents, de-icing, and industrial cleaning.
