  1. 1. Development of a Generic Model for Life Cycle Inventory and Environmental Assessment of Upstream Processes for Electronic Products

    Författare :Anders Andrae; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-In-a-Package; electronic products; upstream processes; life cycle inventory; life cycle assessment;

    Sammanfattning : The goal with the present thesis is to develop tools, methods and models to assess the upstream processes in the life cycle assessment (LCA) methodology for current and new electronic products. The goal is to get a better understanding on how to collect data to be used in a life cycle inventory (LCI) and use life cycle approaches to environmentally assess the electronics. LÄS MER
