2. 1. 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.

4. 2. Fungi-based biorefinery model for food industry waste : progress toward a circular economy

   Author : Pedro Souza Filho; Satinder Kaur Brar; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; filamentous fungi; circular economy; biorefinery; food industry; fungal biomass; bioplastic; resource recovery; Resource Recovery; Resursåtervinning;

   Abstract : The food industry, one of the most important industrial sectors worldwide, generates large amounts of biodegradable waste with high organic load. In recent years, the traditional management methods to treat this waste (e.g., landfilling) have been considered not suitable because they do not exploit the potential of the waste material.

5. 3. Environmental Considerations in the Zero-waste Valorisation of Bauxite Residue : A Life Cycle Perspective

   Author : Peter James Joyce; Anna Björklund; Hellweg Stefanie; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Life Cycle Assessment LCA ; bauxite residue; waste valorisation; Naturally Occurring Radioactive Materials NORM ; Life Cycle Thinking; LCA software; Circular Economy; Livscykelanalys LCA ; bauxitrest; avfallsvalorisering; naturligt förekommande radioaktiva ämnen NORM ; livscykeltänkande; LCA-programvara; cirkulär ekonomi; Planering och beslutsanalys; Planning and Decision Analysis;

   Abstract : Bauxite residue, also known as red mud, is produced in large quantities as a result of alumina refining (the first stage in aluminium production), and is one of the world’s most abundant and important industrial wastes. As demand for aluminium continues to increase and space to store this residue diminishes, the potential to utilise bauxite residue as a secondary resource is increasingly being considered by the alumina industry.

   Abstract : Fruits are among the most important commodities in global trading due to its fundamental nutritional values. In 2012, the fruits supply was 115 kg/person/year, however, only 50 % of the fruits reached their consumers and the rest ended up as waste during the long fruit supply chain. READ MORE

7. 5. Biological Pretreatment and Dry Digestion Processes for Biogas Production

   Author : Regina Patinvoh; Thierry Ribeiro; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid wastes; Dry anaerobic digestion; Textile bioreactor; Plug flow bioreactor; Digestate; Process stability; Pretreatment; Co-digestion; Mesophilic; Resource Recovery; Resursåtervinning;

   Abstract : Biogas technology has been used quite extensively to generate renewable energy from organic wastes while also recycling nutrients in the wastes and reducing harmful emissions. However, the challenges of low biogas yield from recalcitrant and inhibitory solid wastes together with high construction and operation costs of bioreactors have impeded optimal performance through this process.
