  2. 2. Designing out waste - Exploring barriers for material recirculation

    Författare :Isabel Ordonez Pizarro; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; HUMANIORA; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; HUMANITIES; waste sorting; sustainable development; Water; Waste; Urban; waste management; Resources; resource recovery; ​Recycling; designing with waste; recycling;

    Sammanfattning : This doctoral thesis has investigated what hinders material recirculation in society, to later suggest possible ways to support material recirculation in the future. Since material recirculation is proposed as a way to use waste materials for new production, it was deemed relevant to investigate two separate case studies that enabled recirculation from production systems and waste management.
