From dusk till dawn A chemical journey of valorising biorefinery sugars

This thesis explores the sustainable transformation of lignocellulosic biomass and cellulose-containing waste materials into high-value platform chemicals, with a focus on 5-(chloromethyl)furfural (CMF). By addressing the growing need to reduce reliance on fossil fuels, this research contributes to the development of circular economy models in the chemical industry.
The work begins with an extensive review of saccharification technologies, detailing their historical evolution and modern advancements. Experimental investigations focus on optimizing CMF production through acid hydrolysis of wood biomass and extending the process to alternative feedstocks, such as textile, disposable coffee cups, and cigarette butts. These studies highlight key parameters for maximizing CMF yields, showcasing the flexibility and scalability of the process.
A significant portion of the thesis is devoted to the downstream conversion of CMF into 5-(methoxymethyl)furfural (MMF), a precursor for furan-2,5-dicarboxylic acid (FDCA). FDCA is instrumental in producing bio-based polymers like poly(ethylene furanoate) (PEF), a sustainable alternative to traditional plastics.
This research demonstrates the potential of utilizing diverse waste materials as feedstocks for bio-based chemical production, promoting resource efficiency and environmental sustainability. These findings highlights the importance of process optimization and scalability in driving the adoption of sustainable chemical processes.
By integrating fundamental and applied research, this thesis contributes to the broader vision of replacing fossil-based chemicals with renewable alternatives, paving the way for a greener future.
