  1. 1. Dioxins: An Easy Problem to Solve or a Hard-Fought Battle for the Environment? a Case Study of How and Why the Pulp and Paper Industry in Sweden Transitioned Away From Chlorine-Bleaching

    Master-uppsats, Lunds universitet/Sociologiska institutionen; Lunds universitet/Sociologi

    Författare :Marcus Aronsson; [2023]
    Nyckelord :environmental sociology; ecological modernization; treadmill of production; middle-range; industrial transition; Social Sciences;

    Sammanfattning : The situation for the environment is in many ways dire. However, amidst all the negative environmental developments it is easy to neglect the successes that have actually happened. LÄS MER

  3. 2. Assessment of promoter regulation in Pseudomonas putida using GFP and flow cytometry

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Luka Cululejevic; [2022]
    Nyckelord :applied microbiology; Pseudomonas putida; promoter characterization; aromatic compounds; vanillin; guaiacol; Biology and Life Sciences;

    Sammanfattning : Lignin is found in all biomass and is an abundant natural source of aromatic compounds. It has the potential to serve as a renewable raw material for a variety of chemicals currently derived from fossil fuel sources such as muconic acid, an important platform chemical. Kraft lignin is a waste stream from the pulp and paper industry. LÄS MER

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Linnea Rosendal; [2020]
    Nyckelord :wood-based products; biogenic carbon; carbon content; climate change; forest industry; sawn timber; pulp and paper industry; bioenergy; träbaserade produkter; biogent kol; kolinnehåll; klimatförändringar; skogsindustri; sågade trävaror; massa- och pappersindustrin; bioenergi;

    Sammanfattning : Nivåerna av växthusgaser i atmosfären har ökat drastiskt de senaste århundradet, till följd av mänsklig aktivitet. Det krävs en stor omställning för oss människor om klimatförändringarna ska motverkas och för att konsekvenserna för planeten inte ska bli allt för stora. LÄS MER

  5. 4. Dimples in corrugated channels to improve efficiency in plate heat exchangers

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Gustav Karlsson; [2020]
    Nyckelord :Dimples; Plate Heat Exchangers; Heat Transfer Enhancement; CFD; Large Eddy Simulation; Reynolds Averaged Navier Stokes Simulation; chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : The development of new heat exchanger patterns is ever changing. Companies are constantly pushing innovation to satisfy costumer needs in terms of thermal efficiency, reliability and serviceability. In this thesis, the implementation of dimples in the corrugated pattern of a plate heat exchanger is investigated to increase the thermal efficiency. LÄS MER

  7. 5. Microwave Heat Treatment of Black Liquor for the Degradation of Hemicellulose

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Nyckelord :lignin; biofuel; black liquor; heat treatment; microwave heating; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Sammanfattning : The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. LÄS MER
