1. Biochemical conversion of biomass : hydrothermal pretreatment, by-product formation, conditioning, enzymatic saccharification, and fermentability
Sammanfattning : Lignocellulosic residues have great potential as feedstocks for production of bio-based chemicals and fuels. One of the main routes is biochemical conversion, which typically includes pretreatment, enzymatic saccharification, microbial fermentation of sugars, and valorization of hydrolysis lignin. LÄS MER
2. Recycling of cotton textiles: Characterization, pretreatment, and purification
Sammanfattning : In many parts of the world, there are well-established systems for material recycling of metal, glass, and paper. However, no large-scale chemical recycling of textiles currently exists. LÄS MER
3. Unlocking the Potential of Brewer’s Spent Grain : Sustainable Biorefinery Approach and Value-Added Product Generation
Sammanfattning : Brewer’s spent grain (BSG) constitutes 85% of brewing byproducts and 30% of initial malt. In 2021, BSG production reached approximately 37.2 million tons. Owing to its high moisture and nutritional content, BSG is prone to biological deterioration, causing environmental issues when discarded as waste. LÄS MER
4. Advanced Gasification of Biomass/Waste for Substitution of Fossil Fuels in Steel Industry Heat Treatment Furnaces
Sammanfattning : With the current trend of CO2 mitigation in process industries, the primary goal of this thesis is to promote biomass as an energy and reduction agent source to substitute fossil sources in the steel industry. The criteria for this substitution are that the steel process retains the same function and the integrated energy efficiency is as high as possible. LÄS MER
5. Towards a Sustainable Biomass and Waste Refinery Based on Pyrolysis Combined with a Pretreatment Process
Sammanfattning : Some of the naturally accumulated biomass and the massive production of waste by human activities have caused serious environmental problems. The degradation of biomass and waste is one of the main greenhouse gasses (GHG) emission sources. LÄS MER
