  1. 1. Characterization of Compost from Reusable Industrial Streams: : physical, Nutrient, and Microbial Properties

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

    Författare :Ellen Ek Moreau; [2023]
    Nyckelord :Spent mushroom compost; apple orchard waste; soil amendment; compost optimization; circular agriculture;

    Sammanfattning : The increasing global population, combined with soil degradation, poses challenges to food security, and raises concerns about the excessive and long-term use of conventional fertilizers. Evaluating sustainable alternative by-products for their soil-improving properties could offer a potential solution, particularly for Swedish fruit producers who can tap into local waste streams as a circular source of plant nutrients.

  3. 2. Effect of different food by-products on Tenebrio molitor growth and development in an industrial environment

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Anton Laggar Andreasson; [2023]
    Nyckelord :Tenebrio molitor; yellow mealworm; growth; development; industrial farming; wet feed; dry feed; by-products; insects; insects as food and feed; maturation; pupation;

    Sammanfattning : Due to an increasing need for high-quality protein around the world, eyes are turning towards alternative methods of farming, such as insect farms. As insects can eat what humans cannot, e.g. food by-products, they can be a part of sustainable food systems. LÄS MER

  4. 3. Techno-economic and environmental analysis of alternative pathways for urea fertilizer production.

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Wilson Rodriguez; [2023]
    Nyckelord :Urea fertilizer; ammonia; natural gas; biogas; GWP; PE; hydrogen; nitrogen; technologies.;

    Sammanfattning : The increasing global population has placed significant pressure on meeting food demands, leading to the widespread use of fertilizers to enhance crop yields. Urea, being the most used fertilizer globally, has contributed to improved agricultural productivity. LÄS MER

  5. 4. Climate change mitigation from biochar production at farm level : A time dynamic LCA study of wheat

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

    Författare :Louise Jungefeldt; [2022]
    Nyckelord :Pyrolysis; agricultural by-products; life cycle assessment; waste valorization; carbon sequestration;

    Sammanfattning : Agricultural production in Sweden account for a large contribution of the territorial GHG emissions. System optimization, fossil fuel removal and increased circularity is therefore of great importance in order to reach the national net zero emission target by 2045. LÄS MER

  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.
