Biomass based Compositions Comprising Ethylene Glycol A method of purifying a biomass based composition comprising ethylene glycol, the method comprising: (a) subjecting the biomass based composition to at least one distillation step to provide a distillation product, wherein the concentration of ethylene glycol in the distillation product is greater than in the biomass based composition; and (b) subjecting the distillation product to at least one melt crystallisation step to form crystals and a mother liquor, such that the crystals provide a purified biomass based composition, wherein the concentration of ethylene glycol in the purified biomass based composition is greater than in the distillation product.
