  1. 11. Life cycle assessments of arable land use options and protein feeds : A comparative study investigating the climate impact from different scenarios in the agricultural sector

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Malin Karlsson; Linnea Sund; [2016]
    Keywords : LCA; arable land; protein feeds; biofuels; climate impact; fallow; wheat; rapeseed; DDGS; rapeseed meal; soybean meal;

    Abstract : The aim of this study was to investigate and compare the climate impact from different arable land use options and protein feeds aimed for cattle. This has been made by executing two life cycle assessments (LCAs). READ MORE

  3. 12. Integration of III-V light sources for silicon photonics applications

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Louise Laurenius; [2016]
    Keywords : III-V integration; multiquantum well lasers; lateral current injection; silicon photonics; Technology and Engineering;

    Abstract : During the last decades, there have been tremendous improvements in Silicon-based transistor technologies such as operational speed increase as well as size and cost reduction. However, the bandwidth in modern processors is significantly limited by the data transfer in the metallic interconnects. READ MORE

  4. 13. Investigation of possible approaches for consequential electricity markets in ecoinvent

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Malin Pettersson; [2015]
    Keywords : KonsekvensLCA; ecoinvent; elmarknader; långsiktig marginaldata; LCI-modellering; prognoser; Consequential LCA; electricity markets; long-term marginal data; LCI modelling; forecasts; Technology and Engineering;

    Abstract : Version 3 av ecoinvent är den första databasen att erbjuda möjligheten att koppla samman livscykelinventeringar (LCI) utefter olika länkningsalgoritmer. Genom dessa länkningsalgoritmer tar ecoinvent nu fram bakgrundslivscykelinventeringar med både medeldata och långsiktig marginaldata (t.ex. över elmarknader i olika länder). READ MORE

  6. 15. Comparative analysis of biogas slurry and urine as sustainable nutrient sources for hydroponic vertical farming

    University essay from Tema vatten i natur och samhälle; Filosofiska fakulteten

    Author : Vlad Andrei Dumitrescu; [2013]
    Keywords : biogas slurry; hydroponics; LCI; urine;

    Abstract : Sustainable alternatives to using mined nutrients in agriculture must be found in order to limit environmental impacts such as eutrophication, habitat destruction and greenhouse gas emis-sions. Biogas slurry and urine recycled to hydroponic food production (a type of soilless agri-culture) have the potential of providing inorganic nitrogen and phosphorus, the main essential nutrients required for plant growth.
