   Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

4. 2. Biodegradable nanocomposite films based on amylopectin and chitosan

   Author : David Nordqvist; Mikael Hedenqvist; Lars Berglund; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

   Abstract : The use of disposable material is rapidly increasing, today the absolute majority of the material used for these application, i.e. food packages, are oil-based plastics such as polyethylene and polypropylene. Therefore it is of great importance to find alternative biodegradable materials made from renewable resources for this huge growing market. READ MORE

5. 3. Fruit wastes to biomaterials : Development of biofilms and 3D objects in a circular economy system

   Author : Veronika Bátori; Kristiina Oksman; Högskolan i Borås; []
   Keywords : apple pomace; biodegradable; bioplastics; circular economy; orange waste; resource recovery; Resource Recovery; Resursåtervinning;

   Abstract : To address the current plastic pollution problem, the replacement of conventional plastics with bioplastics can be considered. Although the land use of crop cultivation for bioplastics is still negligible, there is an increasing interest in the utilisation of lignocellulosic waste products for the production of bioplastics.

6. 4. 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.
