  1. 21. Wooden Photovoltaic Module Frames : Proof of Concept, Life Cycle Assessment and Cost Analysis

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Tanyew Singer; [2021]
    Keywords : Sustainable Development; Photovoltaics; Wood; Proof of Concept; Life Cycle Assessment;

    Abstract : To mitigate climate change and to achieve global carbon neutrality, the expansion of renewable energy sources is of paramount importance. In this context, photovoltaics (PV) are widely regarded as one of the most promising technologies to lead the transformation towards decarbonized energy systems. READ MORE

  3. 22. Change of heating fuel consumption patterns produced by the economic crisis in Greece

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Panagiotis Patrinos; [2021]
    Keywords : geography; GIS; atmospheric pollution; Greece; household heating systems; heating fuel; economic Crisis; air Quality; satellite data; virtual stations; regression analysis; air pollutants mapping; anthropogenic factors; Earth and Environmental Sciences;

    Abstract : The economic crisis in Greece resulted in a change in residential heating fuels utilized, which in turn resulted in a change of air quality over Greater Athens Area. The aim of this study was to investigate the effects of economic crisis in air quality over Attica by examining the change in air pollutants’ concentrations before, during, and after the onset of the economic crisis in Greece and to associate this change with the change in fuels used for residential heating.

  4. 23. Using blue light reflectance from high-resolution images (6000 dpi) of Scots pine tree rings to reconstruct three centuries of Scottish summer temperatures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Alice De Schutter; Karin Markendahl; [2021]
    Keywords : summer temperature reconstruction; climate change; Scotland; Scots pines; ultra-high image resolution; blue intensity; rekonstruktion av sommartemperatur; klimatförändringar; Skottland; skotska tallar; hög bildupplösning; blå intensitet;

    Abstract : Advances in scanner technology have made it possible to obtain high resolution (6000 dpi) images of tree samples. Due to the images’ increased capability of resolving anatomical wood structures, the new technology could be of benefit to dendroclimatology.  This study attempts to expand on Rydval et al.

  5. 24. Vitality of Sycamore maple (Acer pseudoplatanus) in southwest Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Karin Pershagen; [2021]
    Keywords : invasive species; climate adaptation; tree vitality; epiphytes; sooty bark disease;

    Abstract : Non-native tree species provide alternatives for forestry that needs to adapt to climate change and multiple public demands. In Sweden, Sycamore maple (Acer pseudoplatanus) is a non-native tree species with potential, both in wood production and as a support to biodiversity in woodlands and in urban settings. READ MORE

  6. 25. Agricultural waste and wood waste for pyrolysis and biochar : An assessment for Rwanda​

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Jenny Eliasson; Viktor Carlsson; [2020]
    Keywords : Biochar; Pyrolysis; Biochar feedstock characteristics; Agricultural waste; Composition crop residues; Wood waste; Agricultural production Rwanda; Ultimate analysis; Structural composition; Heating Value; RPR; Biokol; Pyrolysis; Råmaterialegenskaper biokol; Jordbruksavfall​; Sammansättning jordbruksavfall; Träavfall; Jordbruksproduktion Rwanda; Värmevärde;

    Abstract : A high priority in order to combat climate change is disposal of waste. In low-income countries, a large portion of biomass residues generated in the forestry, agricultural and industrial sectors could be usable, instead of being seen as waste. For instance, it could be converted into biochar, which is proven to have many environmental benefits. READ MORE
