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

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

    Sammanfattning : 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.

  3. 2. Production of polyhydroxyalkanoates in biological treatment of industrial wastewaters

    Författare :Simon Bengtsson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyhydroxyalkanoates; mixed cultures; glycogen accumulating organisms GAO ; feast and famine; acidogenic fermentation; activated sludge;

    Sammanfattning : In search of more environmentally friendly polymer materials, polyhydroxyalkanoates (PHAs) have been considered as promising candidates. PHAs exhibit a broad range of material properties, can be produced from renewable resources and are completely biodegradable. LÄS MER

  4. 3. Anaerobic Treatment of Agricultural Residues and Wastewater - Application of High-Rate Reactors

    Författare :Wilson Parawira; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochemical technology; Biokemisk teknik; opaque beer brewery wastewater; UASB; two-stage; co-digestion; sugar beet leaves; solid potato waste; methane yield; biogas; Anaerobic digestion; agricultural residues;

    Sammanfattning : The production of methane via anaerobic digestion of agricultural residues and industrial wastewater would benefit society by providing a clean fuel from renewable feedstocks. This would reduce the use of fossil-fuel-derived energy and reduce environmental impact, including global warming and pollution. LÄS MER
