  1. 1. Antimicrobial materials from cellulose using environmentally friendly techniques

    Författare :Anna Ottenhall; Monica Ek; Josefin Illergård; Orlando Rojas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Antibacterial; antifungal; cellulosic; mold; bacteria; biobased; bio-based; renewable; insulation; packaging; water treatment; water purification; paper filter; paper; membrane; Antibakteriell; fungicid; mögel; antimögel; pappersfilter; vattenrening; membran; papper; bakterier; cellulosa; förpackning; isolering; förnyelsebar; biobaserade; nya material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

    Sammanfattning : There are many aspects that should be considered to achieve truly "environmental friendly" and "sustainable" materials. These include the raw material resource, the energy consumption, the chemicals generated and used, the emissions during production, processing, transportation, disposal and so on. LÄS MER

  4. 3. From bio-based residues to nanofibers using mechanical fibrillation for functional biomaterials

    Författare :Linn Berglund; Kristiina Oksman; Monika Österberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofibers; Industrial residues; Ultrafine grinding; Energy-efficiency; Network formation; Hydrogel; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : Bio-based resource utilization in different forms has been driven by societal, industrial and academic research interests towards the development of “green”, sustainable materials from renewable sources. Within this context, exploiting biomass from different industrial residues is further advantageous from an environmental and economic point of view, leading to minimization of residues by means of waste treatment and to the development of high-addedvalue- products.

  5. 4. Assessment of bio-based fuel ash effects on magnesia refractory materials in quicklime production kilns

    Författare :Naresh Kumar Wagri; Britt M. Andersson; Markus Carlborg; Markus Broström; Matias Eriksson; Bengt-Johan Skrifvars; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory corrosion; ash slag intrusion; lime kiln; MgO refractory; coal ash; olive pomace ash; biomass fuel; crushing strength; potassium K ; silicon Si .; Materials Science; materialvetenskap;

    Sammanfattning : Limestone is calcined into quicklime in lime kilns at temperatures above 1000°C. Heat is supplied through combustion inside the kilns, which are insulated with a lining of refractory bricks to mitigate heat loss and to protect the kiln from the hot, chemically aggressive, and mechanically abrasive environment.

  7. 5. Creating value from bio-residuals : Biogas solutions for biobased industries in Scandinavia

    Författare :Linda Hagman; Mats Eklund; Niclas Svensson; Kari-Anne Lyng; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Biobased industry; Resource efficiency; Biogas development; Sustainability; Nutrients; Biogas; Biobaserad industri; Resurseffektivitet; Biogasutveckling; Hållbarhet; Näring;

    Sammanfattning : This thesis focuses on biogas solutions for biobased industries as substrate management or energy providers. It investigates how such solutions are set up, what factors are important for their development, the effects on society and biobased industries, and the possibility of having biogas solutions as part of a sustainability strategy for biobased industries.
