2. 1. Closed-loop strategy for valorization of starch : From starch to functionalized starch biomaterials and bioplastics

   Author : Duo Wu; Minna Hakkarainen; Elisabetta Ranucci; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Starch; Nano-graphene oxide; Microwave; Valorization; Scaffold; Biomineralization; Bioplastics; Compatibilizer; Plasticizer; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : The desire to utilize renewable resources and avoid wastes drives us to develop new concepts for material design. Non-edible starch feedstocks and starch bioplastic wastes were previously considered useless. READ MORE

4. 2. 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.

5. 3. Volatile Fatty Acids as a Key to Sustainability and Circularity in Polyhydroxyalkanoates Production

   Author : Hoang Danh Vu; Dan Åkesson; Pau-Loke Show; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioplastics; food waste; polyhydroxyalkanoates; volatile fatty acids; immersed membrane bioreactor; acidogenic fermentation; Resource Recovery; Resursåtervinning;

   Abstract : The negative consequences of plastic pollution on both environmental and socio-economic aspects have motivated the development of sustainable and renewable materials to replace the petroleum-based plastic. Polyhydroxyalkanoates (PHAs), which are bioplastics, having an outstanding biodegradability and rather comparable thermal and mechanical properties, are potential alternatives for the replacement of conventional plastics.

6. 4. Bioplastics from Biomass - Acetylation of Xylans with Green Chemistry

   Author : Agnes Stépán; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : There is social, environmental and increasing economic pressure on the industrial sector to substitute non-renewable resources with renewable ones as the increasing World population is exponentially depleting the fossil fuel supplies of the Earth. Each year about 260 million tons of plastics are produced from crude oil and most of it ends up as waste. READ MORE

7. 5. An NADH-Coupled Biosensor for Engineering Redox Metabolism in Saccharomyces cerevisiae

   Author : Jan Knudsen; Teknisk mikrobiologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Yeast; redox balance; glycerol whole-cell biocatalysis; single-cell monitoring; FACS;

   Abstract : Baker’s yeast, Saccharomyces cerevisiae’s potential in industrial biotechnology for producing valuable products e.g. biofuels, bulk chemicals, bio-flavours and pharmaceuticals is established. READ MORE
