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.

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
4. 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
Sammanfattning : Chemical building blocks for plastics can be produced from renewable biomass feedstocks using microbial production organisms, such as yeast or bacteria, in a bioreﬁnery. One class of chemical building blocks that are suitable for production of biobased and biodegradable plastics are dicarboxylic acids, e.g. succinic acid. LÄS MER
