    Abstract : 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.

    Abstract : 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. READ MORE

  6. 24. How do biogas solutions influence the sustainability of bio-based industrial systems?

    Author : Linda Hagman; Mats Eklund; Niclas Svensson; Thomas Prade; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; biorefinery; biomass; circular bioeconomy; sustainability; feasibility; stakeholders; assessments; methods;

    Abstract : Biomass is a valuable and limited resource that should be used efficiently. The potential of replacing fossil-based products with bio-based ones produced in biobased industrial systems is huge. One important aim of increasing the share of biobased products is to improve the sustainability of systems for production and consumption. READ MORE

  7. 25. From bio-based residues to nanofibers using mechanical fibrillation for functional biomaterials

    Author : Linn Berglund; Kristiina Oksman; Monika Österberg; Luleå tekniska universitet; []
    Keywords : 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;

    Abstract : 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.
