He has made significant contributions to the field of renewable chemical processes, particularly in the production of 1,4-butanediol. With a total of 4 patents, his work is recognized for its innovative approach to sustainability.

Latest Patents

One of Marco's latest patents involves a process for the production of 1,4-butanediol from renewable sources. This process includes the preparation of a fermentation broth that comprises 1,4-butanediol and water. It also involves the separation of a liquid fraction containing 1,4-butanediol and water from solid fractions. The liquid fraction must contain 2-pyrrolidone in an amount higher than 80 ppm. The process further includes multiple passages through cation-exchange and anion-exchange resins to achieve specific pH levels. The final distillation results in a composition with a concentration of 1,4-butanediol exceeding 99.0% by weight, while keeping 2-pyrrolidone below 6 ppm. The resulting composition is designed to exhibit an APHA color value after aging of less than 30.
