1. 1. Energy and Environmental Factors in Food and Beverage Production Systems : An Analysis of Tomatoes, Whisky, and Beer

   Författare :Daniel Danevad; Karl Hillman; Ola Eriksson; Hanna Tuomisto; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; environmental systems analysis; waste management; import; local resources; food production; beverage production; circularity; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : Given the anticipated global population of approximately 10 billion by 2050, the task of ensuring adequate sustenance for all within the constraints of Earth's limited resources presents a significant challenge. The production of food and beverages demands considerable energy investment, as well as other essential resources such as water and nutrients. LÄS MER

   Sammanfattning : Measurements of process variations and particle morphology are widely employed in the pulp and paper industry. Two techniques with high potential, infrared thermography and microparticle characterisation, are mainly used qualitatively. LÄS MER

4. 3. Improved mapping of steel recycling from an industrial perspective

   Författare :Alicia Gauffin; Anders Tilliander; Ichiro Daigo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling rate; lifetime; steel scrap; scrap reserve; dynamic material flow modelling; environmental analysis; greenhouse gas emissions; energy; alloy content; forecasting; backcasting; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : The results from this study show that it is possible to obtain data series on the steel scrap collection based on mass balance model on the crude steel production figures by steelmaking reactor type and additional knowledge on process metallurgy as well as information on inputs and outputs into the reactors with an area correlation coefficient of 0,91 compared to data obtained from trade statistics. Furthermore, the study shows that based on a new method it is possible to calculate the time duration of mass flows on a continuous basis. LÄS MER

5. 4. Systems Analysis of Chemicals Production via Integrated Entrained Flow Biomass Gasification : Quantification and improvement of techno-economic performance

   Författare :Jim Andersson; Eric D. Larson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : Lignocellulosic biomass gasification is a promising production pathway for green chemicals, which can support the development towards a more sustainable society where fossil fuels are replaced. To be able to compete with fossil fuels, a highly efficient production of biomassbased products is required in order to maximize overall process economics and to minimizenegative environmental impact.

7. 5. Decarbonising the Stainless Steelmaking through Alloy Solutions

   Författare :Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
