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

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

    Abstract : 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. READ MORE

  4. 2. Treatment of textile wastewaters using combinations of biological and physico-chemical methods

    Author : Maria Jonstrup; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; azo dyes; anaerobic-aerobic treatment; white rot fungi; laccase; photocatalysis; photo-Fenton;

    Abstract : Considerable amounts of water and chemicals are used in the textile industry, and the presence of dyes in the wastewater is a problem of environmental concern. Synthetic dyes are designed to resist light, water and chemicals to improve the quality of the textiles; however, these properties also contribute to their persistence in the environment. READ MORE

  5. 3. Efficient treatment of forest industrial wastewaters : Energy efficiency and resilience during disturbances

    Author : Maria Sandberg; Karin Granström; Jonas Berghel; Alan Werker; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest industry; wastewater; oxygen transfer rate; black liquor; surface active; extractives; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : This work concerns the efficient treatment of wastewaters from pulp and paper mills by means of aerobic biological processes. For treatment processes there are many aspects of efficiency and the present study investigates both energy efficiency and purification efficiency during disturbances. READ MORE

  6. 4. Lipase-Mediated Syntheses of Trimethylolpropane-Based Biolubricant and Cyclic Carbonate

    Author : Amin Bornadel; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Abstract Biocatalysis is considered as benign and efficient alternative to chemical catalysis for organic syntheses. Lipases are the most versatile biological catalysts implemented so far with great potential for production of different chemicals and materials in non-conventional reaction media. READ MORE

  7. 5. Revealing the potential of Nordic microalgae : turning waste streams into resources

    Author : Martin Plöhn; Christiane Funk; Leif J. Jönsson; Maria Barbosa; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; Biotechnology; bioremediation; Heavy metal; Biopolymer; Biodegradable; Sustainability; Chlorella vulgaris; Biochemistry; biokemi; environmental science; miljövetenskap;

    Abstract : As the world's population grows, the demand for fresh water, food, fuel, energy and modern technology increases tremendously. Not only does this require enormous amounts of resources but it also increases the amount of waste and especially wastewater. READ MORE
