  2. 1. The transition to a bio-based economy : Toward an integrated understanding

    Author : Therese Bennich; Salim Belyazid; Pål Börjesson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bio-based economy; bio-economy; sustainability transitions; 2030 Agenda; Sustainable Development Goals; integrated sustainability assessment; systems analysis; Physical Geography; naturgeografi;

    Abstract : The bio-based economy has gained increasing attention in societal and academic debates over the past two decades, and is argued to hold solutions to several pressing sustainability challenges. However, it is not yet clear if the high-reaching aspirations of the bio-based economy can be realized. READ MORE

  4. 2. Exploring bio-based monomers for UV-curable polymer networks

    Author : Sara Brännström; Eva Malmström; Yves Leterrier; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bio-based; polymers; vinyl ether; polyester; photopolymerization; lipase; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Increased environmental awareness and concern has led to a high demand for sustainable, bio-based materials. Consequently, there is a need for research and development of new bio-based polymeric materials that can be synthesized via routes eliminating excessively toxic reactants and by-products. READ MORE

  5. 3. High Performance Bio-based Composites : Mechanical and Environmental Durability

    Author : Newsha Doroudgarian; Kristofer Gamstedt; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : The presented work is a part of the ongoing effort on the development of high performance bio-based composites with enhanced durability, under static and dynamic mechanical loading including the exposure to elevated humidity. The impact of relative humidity on the performance of cellulosic fibers (natural and regenerated), bio-based resins and their composites was studied. READ MORE

  6. 4. An Assessment of the Potential for Bio-based Land Uses on Urban Brownfields

    Author : Shaswati Chowdhury; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban Greenspaces UGSs ; Brownfields; Gentle Remediation Options GROs ; Bio-based CE; Bio-based land use; Circular Economy CE ;

    Abstract : Circular Economy (CE) is expected to accelerate the emerging shift in resource consumption from finite to renewable, and plants are key in enabling the switch as industries would opt more and more for resources with a bio-based origin. Cities have an important role in the process not only as the main consumers of the resources but also because vegetation provides numerous tangible and intangible ecosystem services essential for the wellbeing of urban dwellers.

  7. 5. Sustainable synthetic pathways towards the formation of bio-based polymeric materials

    Author : Susana Torrón; Mats Johansson; Dean Webster; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bio-based; polymers; materials; Kemi; Chemistry;

    Abstract : Increasing environmental and social awareness arising from the use of oil as main source of raw materials, has awaken the interest of many scientists to explore new synthetic pathways for polymer production. These new approaches embrace the use of alternative feedstock and sustainable synthetic routes aiming for enhancing biodegradability and recyclability. READ MORE
