  1. 21. Towards empirically grounded guidance for resource efficiency: Applying, developing and synthesising environmental assessments

    Författare :Daniel Böckin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Circular Business Models; guidelines; business models; synthesis; Life Cycle Assessment; decoupling; resource efficiency; 3D-printing; Circular Economy; waste hierarchy;

    Sammanfattning : Numerous solutions have been proposed to mitigate environmental damage, including resource efficiency and the vision of circular economy. Suggested solutions are often formulated as guidelines and heuristics like in the EU waste hierarchy, so-called R-hierarchies for resource efficiency and various guidelines for circular business models.

  3. 22. A broad perspective on life cycle considerations in product development

    Författare :Ingrid Hallander; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : For products with long life cycles, operational and support costs represent a significant part of the total cost for the product. Moreover, such products frequently tend to be complex and contain a mixture of both mature. stable technology with bng life cycles and new technology with short life cycles. LÄS MER

  4. 23. Essays on labor supply, pension policy, and inequality

    Författare :Johan Gustafsson; Gauthier Lanot; Thomas Aronsson; Katharina Jenderny; Spencer Bastani; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; income inequality; labor supply; life cycle; retirement; public pension; Economics; nationalekonomi;

    Sammanfattning : Paper [I] analyzes the dynamic properties of life-cycle earnings in Sweden using microdata. We study the evolution of permanent and transitory earnings inequality over the period 2002--2015. Our data comes from administrative records gathered in the ASTRID database. LÄS MER

  5. 24. Life Cycle Assessment (LCA) of Food Products and Production Systems

    Författare :Karin Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Life Cycle Assessment (LCA), which is a method for analysis and assessment of the environmental impact caused by product systems, and its application to food products and production systems have been studied. For foods, the complete product system includes: production of inputs to agriculture, agricultural production, industrial refining, storage and distribution, packaging, the household phase and waste management.

  7. 25. Reliability and Life Cycle Cost Modelling of Mining Drilling Rigs

    Författare :Hussan Hamodi; Jan-Gunnar Persson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Sammanfattning : In the context of mining, drilling is the process of making holes in the face and walls of underground mine rooms, to prepare those rooms for the subsequent operation, which is the charging process. Due to the nature of the task, drilling incurs a high number of drilling rig failures. LÄS MER
