    Sammanfattning : Pollution is one of humanity's most pressing problems. Although there are many types of pollution, air pollution is one of the main causes of global warming. LÄS MER

  5. 4. 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.
