2. 1. Optically pure lactic acid production from lignocellulosic biomass

   Author : Joana Coutinho Campos; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lactic acid; enantiomers; softwood; waste viscose; fermentation; Pediococcus acidilactici;

   Abstract : Lactic acid is a platform chemical that can be used for many applications. More recently, optically pure lactic acid—L- or D-lactic acid enantiomers—have been used for the polymerisation to poly-lactic acid (PLA). READ MORE

4. 2. Improving properties of poly(lactic acid) biopolymer for use in food packaging

   Author : Mitul Kumar Patel; Kristiina Oksman; Mohini Sain; Marc Delgado Aguire; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biopolymer; poly lactic acid ; chitin nanocrystals; barrier properties; liquid assisted extrusion; Trä och bionanokompositer; Wood and Bionanocomposites;

   Abstract : The petroleum-based plastics are widely used for food packaging applications because of their low cost, easy processability, and tunable properties to meet the specific needs of food packaging. However, these polymers are non-biodegradable, leading to a substantial amount of plastic waste in both land and marine ecosystems. READ MORE

5. 3. Modelling and Optimisation of Integrated Biotechnical Processes -Application to the Fermentative Production of Lactic Acid from Wheat Flour

   Author : Christina Åkerberg; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; economy; wheat flour; starch; lactic acid; kinetics; simulation; modelling; optimisation; Kemiteknik och kemisk teknologi;

   Abstract : Biotechnical processes are often integrated to increase productivity and yield. It is difficult to predict the effects of process integration and to find optimum conditions for the process. A valuable tool for the evaluation of a complete process is mathematical modelling. READ MORE

6. 4. Development of biocomposites from lactic acid thermoset resins and cellulose fibre reinforcements

   Author : Fatimat Oluwatoyin Bakare; Minna Hakkarinen; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lactic acid; thermoset resin; renewable resources; natural fibre; regenerated cellulose fibre; composite; Resursåtervinning; Resource Recovery;

   Abstract : Synthesis of polymers from renewable origin has been reported by many authors and it has been found out that it has enormous potential and can serve as alternative to conventional thermoplastics and thermosets in many applications. The use of these renewable resources will provide sustainable platforms to substitute fossil fuel-based materials. READ MORE

7. 5. Development of the Steam Pretreatment Process for Production of Ethanol from Lignocellulosic Biomass

   Author : Sanam Monavari; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spruce; Ethanol production; Sugarcane bagasse; SSF; Fermentation; Enzymatic hydrolysis; SO2; Steam pretreatment; Acid catalyst;

   Abstract : At a time when natural petroleum resources are on the verge of depletion, and concern about climate change is increasing, the potential of lignocellulosic material for the production of bioethanol is well recognized. Ethanol can be produced from biomass through enzymatic hydrolysis and fermentation. READ MORE
