1. Bark Biorefinery : Isolation, Characterization and Application
Sammanfattning : To fulfill the United Nations’ 17 sustainable development goals, there is a need to transition from a petroleum-based society toward a more sustainable one which requires new solutions and the production of materials, chemicals, and energy from renewable resources. Using side-stream products from industries to produce value-added products will be economically beneficial. LÄS MER
2. Palladium-catalyzed lignin valorization : Towards a lignin-based biorefinery
Sammanfattning : The work described in this thesis focuses on the cleavage of the β-O-4′ bond, which is the most abundant interunit linkage in the lignin polymer.In the first part, three methods based on palladium catalysis have been developed and their applicability has been verified using lignin model compounds. LÄS MER
3. Chemical characterization in the biorefinery of lignocellulose : Formation and management of oxalic acid and analysis of feedstocks for bioethanol production
Sammanfattning : The pulp and paper industry is entering a new era. Pulp mills will be transformed to biorefineries that produce not only pulp, but also biofuels and novel products from lignocellulose. This thesis addresses problems connected with the industrial transition to environmental-friendly technologies and the implementation of the biorefinery concept. LÄS MER
4. Fungi-Based Biorefinery : Valorization of industrial residuals and techno-economic evaluation
Sammanfattning : Sustainable development of society and industry is necessary for a safer future that is being challenged by environmental pollution, climate change, and scarcity of food and nutrition. Materials considered as waste can be converted into value-added products and energy, hence regained to the economy. LÄS MER
5. 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
