1. Waste-integrated biorefineries : A path towards efficient utilization of waste
Sammanfattning : Waste-management systems have progressed from landfilling and dumping to waste prevention, recycling and resource recovery. In state-of-the-art waste-management industries, waste is separated into various fractions and treated with suitable processes. LÄS MER
2. Innovation for biorefineries – Networks, narratives, and new institutions for the transition to a bioeconomy
Sammanfattning : The transition to a bioeconomy is dependent on transformative changes to technologies, organisations, and institutions, which jointly can be described as a socio-technical change. The thesis contributes to the understanding of how the transition is shaped by expectations on and collaborations for innovation forbiorefineries, which can produce chemicals, fuels, and materials needed in a bioeconomy.

3. Black Liquor Gasification-Based Biorefineries – Determining Factors for Economic Performance and CO2 Emission Balances
Sammanfattning : Biorefineries constitute an attractive future development option for the pulp and paper industry, allowing mills to produce not only pulp or paper but also other value-added products. Black liquor gasification (BLG) is currently being developed as an alternative technology for energy and chemical recovery in kraft pulp and paper mills. LÄS MER
4. Resource mobilisation for energy system transformation
Sammanfattning : A transition to a sustainable path of development will require that fossil fuels are replaced with renewable energy sources and involve, therefore, a large-scale transformation of the energy system. In the EU, offshore wind power and biorefineries have the potential to play an important role in this transformation. LÄS MER
5. SCALING UP RENEWABLE ENERGY TECHNOLOGIES - The role of resource mobilisation in the growth of technological innovation systems
Sammanfattning : Rapid and large-scale diffusion of renewable energy technologies is needed to avoid severe climate changes that would dramatically affect the conditions for human life on Earth. To scale up these technologies involves technological development, but also the alteration of structures that are locked-in to established socio-technical systems. LÄS MER
