  1. 1. Evaluation of Excess Heat Driven Carbon Capture Integrated at a Swedish Pulp Mill

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Frida Nilsson; [2023]
    Keywords : CCS; BECCS; pulp and paper industry; pulp mill; excess heat; MEA; HPC; AMP; DMSO; chemical engineering; environmental engineering; Technology and Engineering;

    Abstract : As the atmospheric carbon dioxide keeps increasing, bioenergy with carbon capture and storage (BECCS) is getting increased attention as a measure to reduce the emissions of carbon dioxide. It is especially interesting in Sweden where the extensive paper and pulp industry constitutes point sources of biogenic carbon dioxide. READ MORE

  3. 2. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anne Rebotzke; [2023]
    Keywords : mercury; lake sediment; primary productivity; algal scavenging; biogenic silica; diatom proxy; chlorophyll-a; organic matter;

    Abstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE

  4. 3. Life cycle assessment of timber high-rise building structures : Case study of a project examined in the context of French environmental regulation (RE2020)

    University essay from KTH/Byggnadsmaterial

    Author : Corentin Le Gall; [2023]
    Keywords : ;

    Abstract : The damages that the building sector does to the environment can no longer be ignored and need to be approached with a life cycle assessment (LCA). Advantages to build in wood and to build dense cities lead to a potential “two birds in one stone” effect regarding high-rise massive timber construction. READ MORE

  5. 4. Towards low carbon buildings: A case study in Sweden

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Huynh Tuan Tran; Victor-Antoine Delorme; [2023]
    Keywords : Life cycle assessment; Environmental impact of building materials; Carbon neutrality; Biobased material; Biochar; Cross Laminated Timber; Biogenic carbon; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : This study comprehensively evaluated the global warming potential of an office building in a newly built Scandinavian neighbourhood seeking to reach sustainability. The primary objective of the research was to support the city authorities of Helsingborg by providing valuable insights into actual carbon emissions at the building level and proposing measures to minimize these emissions to achieve climate neutrality by 2030.

  6. 5. Techno-Economic Assessment of a Post-Combustion CO2 Capture Unit in SCA Östrand Pulp Mill

    University essay from KTH/Energiprocesser

    Author : Abhishek Subramani; [2022]
    Keywords : Bioenergy with Carbon Capture and Storage; Post-Combustion Capture; Monoethanol Amine; Chilled Ammonia; Techno-Economic Assessment;

    Abstract : The Paris Agreement has ambitious targets to limit the global warming below 1.5 °Cin the 21st century. This goal is reflected in the national climate targets, for example, Sweden aims to achieve net zero greenhouse gas emissions by 2045, and thereafter achieve negative emissions. READ MORE
