1. 6. Bio-based recovery of organic carbon from municipal waste streams : Process optimization and microbial community dynamics

   Författare :Isaac Owusu-Agyeman; Zeynep Cetecioglu; Elzbieta Plaza; Piet Lens; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

   Sammanfattning : Resource recovery from waste contributes to the transition to a sustainable society. Municipal organic wastes have enormous potential for resource recovery due to the inherent organic content which makes it possible to obtain bio-based chemicals and bioenergy. LÄS MER

3. 7. Analyzing Material Properties for Efficient Processing of Spruce to Ethanol

   Författare :Magnus Wiman; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Fuel production from renewable resources will likely be a prerequisite for reducing the negative anthropogenic impact on the environment and, at the same time, ensuring future energy security. In this thesis, the conversion of typical Swedish biomass, mainly Norway spruce, to ethanol was studied. LÄS MER

4. 8. Fuel Ethanol Production from Corn Stover: Optimization of Steam Pretreatment and Improvement of Simultaneous Saccharification and Fermentation

   Författare :Karin Öhgren; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuels and explosives technology; petrochemistry; Carbochemistry; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Energiforskning; corn stover; Energy research; prehydrolysis; enzymatic hydrolysis; SSF; SO2; steam pretreatment; Ethanol production; Petrokemi; bränslen; sprängämnen; pentose fermentation;

   Sammanfattning : Fuel ethanol, produced from biomass, could well be tomorrow's replacement for gasoline. This thesis deals with the production of fuel ethanol from corn stover using an enzymatic process consisting of the following main steps: steam pretreatment of the raw material, enzymatic hydrolysis, fermentation of the sugars and ethanol refining.

5. 9. Process development for platform chemical production from agricultural and forestry residues

   Författare :David Nickel; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Biorefinery; pretreatment; lignocellulose; multi-feed SSCF; preadaptation; multi-scale variability analysis; platform chemicals; lactic acid; logging residues; mixed feedstocks; ethanol;

   Sammanfattning : As part of a bio-based economy, biorefineries are envisaged to sustainably produce platform chemicals via biochemical conversion of agricultural and forestry residues. However, supply risks, the recalcitrance of lignocellulosic biomass, and inhibitor formation during pre­treatment impair the economic feasibility of such biorefineries. LÄS MER

7. 10. Nutritional Limitations of a Green Protein Shift with Focus on Iron

   Författare :Cecilia Mayer Labba; Chalmers tekniska högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; phytate; non-heme iron absorption; antinutrients; protein shift; protein extract; meat substitutes; plant-based; fava bean; zinc bioavailability; iron bioavailability; sustainable nutrition;

   Sammanfattning : A dietary shift into plant-based diets (PBD) to reduce the climate footprint is advocated. Effects on nutrition and health from a modern PBD, composed of replacement products based on protein extracts are however currently unknown. LÄS MER
