  3. 2. Waste Analysis on a Production Line - A Case Study

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Sanna Treptow; Déspina Karida; [2023]
    Nyckelord :Sustainable manufacturing systems; Sustainable production; Lean production; Just in Time Production JiT ; Kanban; Waste; Environmental Value Stream Mapping EVSM ; Production Performance Matrix PPM ; Key Performance Index KPI ; Technology and Engineering;

    Sammanfattning : This study aims to assist Swedish company Clemondo AB in reducing waste in production, where the goal is to determine where waste appears as well as make suggestions for potential improvements, which are presented as Key Performance Indices (KPIs) and minimized manufacturing costs. Citation chaining is used to retrieve extant literature, while other productions and process-related information are gathered through observations and discussions. LÄS MER

  4. 3. Jämförelse av den strukturella prestandan mellan olika klimatförbättrade betongtyper

    M1-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Författare :Ahmed Shurie; [2022]
    Nyckelord :;

    Sammanfattning : Betong är ett av de viktigaste byggnadsmaterialen som används i byggbranschen och det har använts i tusentals år på grund av dess egenskaper som är lämpade för många applikationer. Betong är en produkt med högt koldioxidutsläpp vilket beror på användningen av cement vid dess tillverkning. LÄS MER

  5. 4. Optimization of the sorting process in PVC-floor recycling : Scenarios to optimize economic and environmental aspects of the upscaling sorting process

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Författare :Emelie Jonsson; Birkir Pálsson; [2021]
    Nyckelord :Circular economy; Sorting process; PVC; Automation; CO2 emission; Cirkulär ekonomi; Sorteringsprocess; PVC; Automatisering; CO2-utsläpp;

    Sammanfattning : Background: The industrial economy has been dominated by a one-way production and consumption model. Closing loops for materials has seen an upswing in popularity. The focus though has been on the environmental aspects instead of the economic benefits from implementing closed loops. LÄS MER

  7. 5. Stabilizing biogas processes at high ammonia : effects of acetate pulse-feeding on the microbial population

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Oscar Dolk; [2020]
    Nyckelord :biogas; anaerobic digestion; ammonia inhibition; acetate enrichment;

    Sammanfattning : This study investigated the problem of ammonia inhibition in biogas reactors, commonly occurring when protein rich substrates are used in anaerobic digestion processes. Ammonia inhibition is one of the foremost causes of failure in anaerobic digestion, leading to process instability, with symptoms commonly expressed as; reduction in biogas produced, decreased methane content in the gas and accumulation of volatile fatty acids.
