    University essay from SLU/Dept. of Animal Environment and Health

    Author : Madeleine Persson; [2024]
    Keywords : stunning methods; slaughter; animal welfare; carbon dioxide; high-expansion foam; nitrogen; argon;

    Abstract : There are several stunning methods used for the commercial slaughter of pigs. The two most common are electric stunning and stunning with carbon dioxide gas. It has been shown that there are several problems related to animal welfare in the stunning methods used today in commercial slaughter. READ MORE

  3. 2. Air quality around preschools in Gothenburg: an evaluation of measurement methods

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Emma Forsmalm; [2023-06-21]
    Keywords : low-cost sensors; passive diffusion samplers; pick-ups and drop-offs; regulatory measurements;

    Abstract : In this study the air quality around four different preschools, chosen to represent different local traffic environments, was measured and the measurement methods used were evaluated. The aim was to compare the information retrieved using different methods, discuss the possible applications of them and finally see if more specific activities, in this case pick-ups and drop-offs, could be seen in the data retrieved.

  6. 5. Carbon Capture from Biomass Boiler Flue Gas Emissions using Microalgae : A Case Study

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Graham Kirn; [2023]
    Keywords : ;

    Abstract : Capture and storage of carbon dioxide (CO2) is expected to play an important role in climate change mitigation efforts intended to limit global warming to 1.5 °C. Bioenergy with carbon capture and storage (BECCS), in which carbon is captured during energy generation from sustainably sourced biomass fuels, is of particular interest in Sweden. READ MORE
