  1. 1. Användning av biokol vid odling av ostronskivling

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

    Författare :Lilja Bergquist; [2023]
    Nyckelord :ostronskivling; biokol; Pleurotus ostreatus; svampodlingssubstrat;

    Sammanfattning : För att säkra vår matproduktion i framtiden står vi inför utmaningar och ett behov av att skapa mer cirkulära system. Det här arbetet inkluderar biokol och svampodling, två branscher på framkant för att skapa mer cirkularitet, gynna matproduktionen och erbjuda alternativa näringskällor. LÄS MER

  3. 2. Production of polymers from a papermills wastewater using HTC substrate. : Investigating the viability of using wastewater sludge from Skoghalls’ papermill in combination with filtrate from HTC of sewage sludge to produce biological plastic producing polymers.

    Kandidat-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Författare :Regan George; [2023]
    Nyckelord :PHA; HTC-substrate; Polymer;

    Sammanfattning : Since their conception, plastics have been a dominant product due to the versatility of use, and readily available raw materials. However, the production and consumption of synthetic plastics have continued to increase over the years, leading to a significant rise in plastic waste and its associated environmental impacts, such as the detrimental effects plastic waste has on ecosystems, including the presence of toxic microplastics and risks to marine life, are becoming the focus of criticism.

  4. 3. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Mehrzad Ghassemi; [2022]
    Nyckelord :Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

    Sammanfattning : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes.

  5. 4. Soil carbon relations in Swedish agriculture : A GIS analysis and literature review of soil characteristics at farm level

    Master-uppsats, Linköpings universitet/Institutionen för tema

    Författare :Christiane Schulze; [2022]
    Nyckelord :Carbon sequestration; Crop yield; Management practices; Soil organic carbon; Soil organic matter; Sweden; northern Europe;

    Sammanfattning : Carbon storage in agricultural soils is an important measure to mitigate climate change. As the soil management techniques can greatly influence the amount of carbon stored in agricultural soils, the influence of different managements was analyzed in a literature review for northern Europe and Sweden.

  7. 5. Assessing the suitability of using the by-product Petrit-E from steel production as agricultural fertilizer

    Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Eva Galyas; [2022]
    Nyckelord :steel slag; fertilizer; soil; leaching test;

    Sammanfattning : Due to the growing population, waste generation and food supply industries need to move towards a circular economy and take advantage of by-products. Metallurgical slag is a main by-product during steel production which contains several valuable minerals and can be used for several further applications, including water purification and agriculture.
