2. 1. Techno-economic evaluation of integrated lignocellulosic ethanol production

   Author : Elisabeth Joelsson; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distillers dried grain with solubles; biorefinery; modelling; Aspen Plus; biogas; logging residues; spruce; wheat straw; wheat grain; heat; integration; pinch analysis; techno-economic evaluation; first generation; second generation; Ethanol; Lignocellulosic material;

   Abstract : Sweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. READ MORE

4. 2. Fermentation of lignocellulosic material : a study on bacterial contamination and yeast physiology

   Author : Emma Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; yeast physiology; energy metabolism; Lignocellulosic bioethanol; bacterial contamination;

   Abstract : Progressive depletion of oil and conventional fossil fuels, an increased energy demand and an increased struggle for national energy security has led to the development of alternative biobased fuels, bioethanol being one of them. Bioethanol can be made from many different raw materials, and based upon this are classified as 1st generation and 2nd generation. READ MORE

5. 3. Lipid production from lignocellulosic material by oleaginous yeasts

   Author : Jule Brandenburg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Oleaginous yeasts are a potential lipid source for production of fuels, chemicals and food or feed and use of lignocellulosic biomass as feedstock is considered a sustainable approach. Pre-treatment of lignocellulose is required to release the major carbon sources, glucose, xylose and other sugars for lipid production by oleaginous yeasts, but also releases inhibitory compounds.

6. 4. Strategic raw material supply for the particleboard-producing industry in Europe : Problems and challenges

   Author : Johann Trischler; Johan Bergh; Rupert Wimmer; Linnéuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass production; Lignocellulosic raw material; Non-wood plants; Particleboard; Pulp and paper; Recycling; Thermal energy recovery; Wood plants; Forestry and Wood Technology; Skog och träteknik;

   Abstract : Particleboard was invented to increase the utilization of wood and it soon became an important core material for furniture production. Nowadays, other industries such as the pulp and papermaking industry and the thermal energy recovery industry claim the same type of raw material. READ MORE

7. 5. Spectroscopic characterization of lignocellulosic biomass

   Author : Mikael Thyrel; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis focuses on characterization of organic components and inorganic elements in lignocellulosic biomass. The chosen biomass models were mostly wood from conifers and straw from rhizomatous grasses but also forest-based residues and agro-based plants. READ MORE
