  1. 21. Comparison between conventional and organic farming systems : an LCA study of milk production

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Yue Gu; [2021]
    Nyckelord :;

    Sammanfattning : Agriculture has always been an important part in people’s daily life and has been developing over centuries with the development of technology and contributing to the rise of civilizations. Based on the production method, conventional and organic farming systems are currently the two main farming systems. LÄS MER

  3. 22. Biobased carbon aerogels incorporated with zeolite nanoplates for carbon dioxide adsorption

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Maria Harila; [2021]
    Nyckelord :biobased; carbon aerogel; lignin; cellulose nanofiber; adsorption; carbon dioxide; zeolite nanoplate;

    Sammanfattning : Over the last 100 years there has been an increase of greenhouse gases (CO2, CH4 and N2O) in the atmosphere. These gases cause several problems with the climate on Earth, such as increasing problems with extreme weather. One way to decrease the outlet of carbon dioxide is by adsorption and capture of CO2.

  4. 23. Spatial variation in GHG emissions from drained organic forest soils : implications for Swedish UNFCCC reporting

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Anna Oskar; [2021]
    Nyckelord :greenhouse gas; carbon dioxide; methane; nitrous oxide; peat; drainage; ditch; GHG inventory;

    Sammanfattning : Drainage of organic soils for forestry generally increases soil CO2 and N2O emissions but decreases CH4 emissions. Under the United Nations Framework Convention on Climate Change (UNFCCC) countries provide annual national inventories of anthropogenic greenhouse gas (GHG) emissions and removals, which includes emissions of GHGs from drained organic forest soil.

  5. 24. Bokashi : köksavfallshantering utan växthusgaser?

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Kajsa Hillberg; [2021]
    Nyckelord :EM; Bokashi; GHG emissions; Greenhouse gas; CO2; CH4; N2O;

    Sammanfattning : EM Bokashi is a fermentative treatment used for kitchen waste, branded as a climate friendly alternative to compost with low or no greenhouse gas (GHG) emissions. This study aims to examine if these claims are true. LÄS MER

  7. 25. Greenhouse gas emissions from compacted peat soil

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Antonia Hartmann; [2021]
    Nyckelord :carbon dioxide; compression index; Peatland agriculture; recompression index; sand addition; soil compaction;

    Sammanfattning : Cultivated peat soils are a main driver for CO2 and N2O emissions, while the gas fluxes are dependent on intrinsic soil properties and land use. Sand addition into peat soils might reduce greenhouse gas (GHG) emissions and enhance soil strength, and thus the ability to tolerate soil compaction. LÄS MER
