Design and analysis of biorefineries based on raw glycerol: Addressing the glycerol problem

► We have modeled the production of nine added-value products from glycerol. ► We consider chemical and biochemical routes under different production scenarios. ► We present a first design approach to build a system of biorefineries based on crude glycerol. ► We conclude the more profitable added-value products from glycerol are 1,2 and 1,3 propanediols.
