2. 1. The role of biobased building materials in the climate impacts of construction : Effects of increased use of biobased materials in the Swedish building sector

   Author : Diego Peñaloza; Magnus Wålinder; Martin Erlandsson; Andreas Falk; Johanna Berlin; Dimitris Athanassiadis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; timber buildings; timber bridges; biobased building materials; dynamic LCA; climate change mitigation; building stock; scenario analysis; biogenic carbon; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : A significant share of the global climate change impacts can be attributed to the construction sector. One mitigation strategy is increasing the use of biobased materials. Life cycle assessment (LCA) has been used to demonstrate the benefits of this, but forest complexities create uncertainty due to omission of key aspects. READ MORE

4. 2. Functional Nanocellulose–Tannin Materials Inspired by Nature and Traditional Processes

   Author : Konstantin Kriechbaum; Lennart Bergström; Alain Dufresne; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cellulose; Nanofibrils; Tannin; Biobased; Films; Foams; Moisture resistance; Energy efficiency; Materials Chemistry; materialkemi;

   Abstract : Renewable and biodegradable alternatives to fossil-based materials are essential as concerns over depleting finite resources and the pollution of our ecosystems are growing. Abundant, highly anisotropic, and mechanically strong cellulose nanofibrils (CNF) are attractive building blocks for the fabrication of high-performance biobased materials that can compete with their conventional fossil-based counterparts.

5. 3. Thermal Conductivity of Hygroscopic Foams Based on Cellulose Nanomaterials

   Author : Varvara Apostolopoulou-Kalkavoura; Lennart Bergström; Tatiana Budtova; Stockholms universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thermal conductivity; cellulose nanomaterials; foams; hygroscopic; super-insulating; phonon scattering; moisture uptake; heat transport; Materials Chemistry; materialkemi;

   Abstract : Biobased super-insulating materials could mitigate climate change by minimizing the use of petroleum-based materials, creating artificial carbon sinks and minimizing the energy needed to maintain pleasant interior conditions. Cellulose nanomaterials (CNM) produced from abundantly available cellulose sources constitute versatile, highly anisotropic raw materials with tunable surface chemistry and high strength. READ MORE

6. 4. Exploring different thermoplastics from lignocellulosic building blocks and monomers

   Author : Olivier Bonjour; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biobased plastics; Biobased polymers; Polymethacrylates; Polycarbonates; Polyesters; Poly beta-thioether ester s; Chemical recycling; Biobased plastics; Biobased polymers; Polycarbonates; Polymethacrylates; Poly beta-thioether ester s; Polyesters; Chemical recycling;

   Abstract : The need to replace conventional fossil-based plastics is becoming more imperative. As climate change is more visibly affecting our society, employing non-sustainable resources to produce plastics is aggravating the problem. READ MORE

7. 5. Characterisation of thermally modified wood for use as component in biobased building materials

   Author : Susanna Källbom; Magnus Wålinder; Dennis Jones; Kristiina Lillqvist; Kristoffer Segerholm; Marko Petrič; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermally modified wood TMW components; surface properties; inverse gas chromatography IGC ; water sorption; dynamic vapour sorption DVS ; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : The building sector shows growing interest in biobased building materials. Wood components, here defined as ground or milled wood, i.e. by-products (residuals/residues) from wood processing, such as sawdust or shavings, are valuable raw materials for new types of durable biocomposites suitable for outdoor building applications.
