2. 16. Nutrient Recovery as an Added Benefit to Harvests of Photosynthetic Marine Biomass : A Holistic Systems Perspective on Harvesting Marine Microalgae, Cyanobacteria, and Macroalgae

   Author : Joseph Pechsiri; Fredrik Gröndahl; Maria Malmström; Angela Wulff; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Industrial Ecology; Industriell ekologi;

   Abstract : As a result of increasing environmental burdens from anthropogenic activities andresource scarcity, interest for the development of solutions utilizing photosyntheticmarine biomass has also been increasing in both academia and industries. Medium tolarge scale production and harvest of photosynthetic marine biomass have beenpracticed to achieve numerous services, including improving tourism industries,production of biofuels, and production of food/feed.

4. 17. Decarbonising the Stainless Steelmaking through Alloy Solutions

   Author : Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; optimization; raw material; process; quality; decarbonisation; rostfritt stål; optimering; material; process; kvalitet; avkarbonisering; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. READ MORE

5. 18. Fossil Free or Not - That is the Question

   Author : Torbjörn Skytt; Bengt-Gunnar Jonsson; Monica Odlare; Markku Rummukainen; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fossil free; Carbon balance; Carbon flow; Energy flow; Climate mitigation; Governing climate change; Forest carbon;

   Abstract : This is an evaluation of Jämtland County’s ability to achieve its climate targets to reduce greenhouse gas (GHG) emissions with 10% annually, and to become fossil fuel free 2030. There is a risk that the target to become fossil fuel-free, relying primarily on outtake of forest biomass, contradicts with the target in the UN Paris Agreement to keep the global temperature increase below 1.

6. 19. Processing Lignocellulosic Biomass into Ethanol - Implications of High Solid Loadings

   Author : Benny Palmqvist; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulose; Bioethanol; High solid loadings; Biomass rheology; Enzymatic hydrolysis; Simultaneous Saccharification and co-Fermentation;

   Abstract : Fuel ethanol from lignocellulosic biomass has the potential to provide a sustainable replacement for traditional oil-based fuels. This dissertation assesses the processing of three different lignocellulosic materials – spruce, wheat straw and giant reed – at industrially relevant solid loadings. The work is divided into two main parts. READ MORE

7. 20. High Temperature Fatigue Behaviour of Austenitic Stainless Steel : Microstructural Evolution during Dwell-Fatigue and Thermomechanical Fatigue

   Author : Hugo Wärner; Mattias Calmunger; Johan Moverare; Guocai Chai; Sten Johansson; Martina Zimmermann; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The global energy consumption is increasing and together with global warming from greenhouse gas emission, a need for more environmentally friendly energy production processes is created. Higher efficiency of biomass power plants can be achieved by increasing temperature and pressure in the boiler section, this would increase the generation of electricity along with the reduction in emission of greenhouse gases e.
