16. Evaluation of emerging forest-industry integrated biorefineries : Exploring strategies for robust performance in face of future uncertainties
Sammanfattning : Biorefineries have been promoted to reduce dependency on fossil resources, increase self-sufficiency, and revitalise rural areas. Commercial deployment of forest-based biorefineries has been slow, although academic research has identified several technology options as promising in terms of both costs and resource usage. LÄS MER
17. Insights to beachcast management on Gotland, Sweden : An Industrial Ecology perspective on waste-resource ambiguity
Sammanfattning : Beachcast or beach wrack, washed-up algae and seaweed, used to be a highly sought-after agricultural resource (fertiliser and soil conditioner) in coastal communities around the world before being replaced by chemical fertilisers, but considering the talks of a circular bio-economy – can we reintroduce it? Since the abandonment of beachcast in agriculture, the amount of beachcast has significantly increased as an effect of eutrophication caused by the use of chemical fertiliser, and the material is commonly considered waste. Meanwhile, soils have degraded and need the multiple positive effects on agroecosystems that beachcast could provide. LÄS MER
18. Assessing District-Heating Sustainability – Case Studies of CO2 Mitigation Strategies and Environmental Cost Accounting
Sammanfattning : District heating (DH) may play an important role in achieving the EU goal of a secure, competitive and sustainable energy supply. Integrated energy solutions based on technologies, such as biomass gasification for transport fuel, electricity and heat production and heat-driven absorption cooling, create new optimisation possibilities through the linkage between heat, power, cooling and transport fuel markets which may reduce the global warming contribution of the energy sector.

19. The Economics of Biofuel Development : Policy Incentives and Market Impacts
Sammanfattning : This thesis examines the economics of biofuel development by studying the forest raw material market impacts of increased biofuel production, as well as the role of specific policy incentives. Paper [I] presents an economic assessment of two different developments – both implying an increased demand for forest ecosystem services – and how these could affect the competition for forest raw materials.

20. Design and analysis of solid oxide electrolysis-based systems for synthetic liquid fuels production
Sammanfattning : During the past decades, considerable attention has been dedicated to renewable energy systems. This is due to the increased awareness regarding greenhouse gas emissions as well as limits of the future availability and reliability of conventional energy and power systems. LÄS MER
