2. 1. Bio-based Composites from Soybean Oil Thermosets and Natural Fibers

   Author : Kayode Adekunle; Högskolan i Borås; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; bio-based thermoset resins; natural fibres; hybrid composites; renewable resources; mechanical analysis; compression molding; lyocell fiber; Energi och material; Resursåtervinning; Resource Recovery; hybrid composite; natural fiber; Bio-based thermoset resin;

   Abstract : In order to reduce over-dependency on fossil fuels and to create an environment that is free of non-degradable plastics, and most importantly to reduce greenhouse gas emission, bio-based products are being developed from renewable resources through intense research to substitute conventional petrochemical-based plastics with renewable alternatives and to replace synthetic fibers with natural fibers. Many authors have done quite a lot of work on synthesizing polymers from renewable origin. READ MORE

4. 2. Fermentative hydrogen and methane productions using membrane bioreactors

   Author : Julius Akinbomi; Högskolan i Borås; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Encapsulation; Inhibition; hydrodynamics; hydrogen; methane; fruit flavour; Membrane bioreactor; Resursåtervinning; Resource Recovery;

   Abstract : The role of energy as a stimulant for economic growth and environmental sustainabilityof any nation has made the focus on green fuels, including fermentative hydrogen (bioH2) andmethane (bioCH4), to be a priority for the World’s policy makers. Nigeria, as the most populousAfrican country, with worsening energy crisis, can benefit from the introduction of the bioH2 andbioCH4 technologies into the country’s energy mix, since such technologies have the potential ofgenerating energy from organic wastes such as fruit waste.

5. 3. Pretreatment of cellulosic waste and high rate biogas production

   Author : Solmaz Aslanzadeh; Högskolan i Borås; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Biogas; Two-stage anaerobic digestion; N-methylmorpholine N-oxide NMMO pretreatment; Lignocelluloses; Textile waste; Biofuels; Resursåtervinning; Resource Recovery;

   Abstract : The application of anaerobic digestion technology is growing worldwide, mainly because of its environmental benefits. Nevertheless, anaerobic degradation is a rather slow and sensitive process. One of the reasons is the recalcitrance nature of certain fractions of the substrate (e.g. READ MORE

6. 4. Development of thermoplastic biocomposites based on aligned hybrid yarns for fast composite manufacturing

   Author : Behnaz Baghaei; Högskolan i Borås; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid yarns; Mechanical properties; Porosity; Weaving; Alkali treatment; Compression moulding; Resursåtervinning; Resource Recovery;

   Abstract : The interest in natural fibres as reinforcement for composite materials has been steadily increasing due to their attractive mechanical properties and the possibility of making more eco-friendly materials. Currently, various alternatives are being introduced for commercial applications, as fibres such as hemp, jute and flax exhibit properties, which make them appropriate for structural composite components.

7. 5. Development of biocomposites from lactic acid thermoset resins and cellulose fibre reinforcements

   Author : Fatimat Oluwatoyin Bakare; Minna Hakkarinen; Högskolan i Borås; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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
