Abstract

The biorefinery approach involves processing biomass into energy, food, feed, biofuels, and biobased chemicals, with the goal of maximizing value and minimizing waste. Seaweed, or macroalgae, has high potential to be used as input for such biorefineries. This is, among other reasons, due to its high carbohydrate and low lignin content. This composition facilitates the depolymerization and conversion into biofuels and biobased chemicals. Despite these advantages, the use of macroalgae as input for biorefineries is still in its infancy, and only single-product outlets (e.g., food/feed) have been commercialized. To stimulate the development of seaweed biorefineries, conversion to novel high-value platform chemicals, for instance, to be used as building blocks for advanced plastics, is highly desirable. The research reported in this PhD thesis aims to aid this development and focuses on developing efficient routes for the conversion of a representative red macroalgae (Eucheuma cottonii) to two important platform chemicals (5-hydroxymethylfurfural and levulinic acid). Experimental studies were conducted to improve product yields by using tailored catalysts and optimizing process conditions.
