  1. 1. Predicting Treatment Performance Using Ternary Plot : Macronutrients’ impact on biomass conversion efficiency

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Madeleine Gobl; [2022]
    Nyckelord :Black soldier fly; organic waste treatment; biomass conversion efficiency; treatment performance; macronutrients; ternary plot; organic waste; amerikansk vapensflugan; triangulär diagram; organiskt avfallsbehandling; organiskt avfall; behandlingseffektivitet; biomassomvandlings-effektivitet; makronäringsämnen;

    Sammanfattning : Black soldier fly larvae (BSFL) waste treatment is becoming a more sought-after organic waste treatment since it produces larvae for animal feed as well as fertilizer, the need for prediction and optimization of treatment performance increases. This study aims to predict biomass conversion efficiency (BCE) for waste going into treatment, using only the nutritional data from other studies as it could give a good performance estimation while using available data.

  2. 2. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Fanny Blom; [2022]
    Nyckelord :wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

    Sammanfattning : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. LÄS MER

  3. 3. Wool you look at that? Sheep wool pellets as fertilizer in container-grown crops with short cultivation time

    Kandidat-uppsats, SLU/Department of Biosystems and Technology (from 130101)

    Författare :Joy Hill; [2022]
    Nyckelord :Sheep wool pellets; sheep wool; organic fertilizer; container cultivation; basil;

    Sammanfattning : Sheep wool pellets (SWP) is an organic fertilizer that capitalizes an excess waste product of sheep husbandry, providing a way to reduce the environmental impact of wool and recycling it back into the production cycle. With a NPK of 10-0,1-4,5 and other trace elements, the pellets are considered a well-rounded fertilizer, but with a long degradation time. LÄS MER

  4. 4. Medvetenheten om klimatfrågan bland elever i gymnasieskolan och vuxenutbildningen : En empirisk pilotstudie

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Mattias Andersson; [2021]
    Nyckelord :climate change; environmental education; sustainable development; upper secondary school; adult education; klimatfrågan; klimatförändring; hållbar utveckling; miljöundervisning; gymnasieskolan; vuxenutbildning;

    Sammanfattning : The purpose is to study, in a pilot survey, the consciousness of climate change among pupils in secondary school and in adult education. These are the research questions: - What consciousness of climate change do the pupils have? - What are the differences in respect of climate change consciousness between men and women, pupils in adult education and in upper secondary school and pupils in pre-university programmes and in vocational programmes? ”Climate Change Consciousness” is constructed as a concept consisting of ecological, social and economic dimension as well as the components knowledge, attitudes and behaviour.

  5. 5. Considerations and Novel Technologies in Industrial Water Treatment - Treatment of challenging wastewater

    Master-uppsats, KTH/Kemiteknik

    Författare :Nils Toll; [2021]
    Nyckelord :Industrial water treatment; considerations; novel technologies; BOD; COD; organic waste; heavy metals; desalination; Industriell vattenrening; nyckelfaktorer; nya teknologier; organiskt avfall; tungmetaller; avsaltning;

    Sammanfattning : Industriell vattenrening är ett extremt viktigt område inom Miljöskyddsteknik då 60% av allt sötvatten inom Sverige används av industrier. Substanser som PFAS, aromatiska textilfärger, fenol och läkemedelsrester är extra utmanande då dessa kan vara gifta för biologisk rening. LÄS MER
