  1. 1. Urea-Based Treatments of Unretted Hemp Fibres from Residual Streams

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Danilo Esteban Ortiz Sarasty; [2023]
    Nyckelord :Finola waste; stalks; unretted hemp fibres; degumming; cold urea alkali; microwave-urea;

    Sammanfattning : More sustainable and efficient degumming methods are required to extract finner bast fibres, especially from agro-industrial waste streams such as stalks from hemp for food purposes. For this reason, in this study, two urea-based treatments were evaluated as degumming alternatives for unretted hemp fibres from residual streams, one at cold and alkaline conditions (CUA) and the other in combination with microwave radiation (MWU).

  4. 3. Exploration of ways to utilize wheat chaff through fungal substrate conversion : a base for animal feed or substrate for cultivation of edible mushrooms

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Caroline Sandberg; [2022]
    Nyckelord :harvest residues; chaff; oyster mushroom; agro-waste reduction; mushroom production;

    Sammanfattning : The shift towards a more sustainable food system emphasises a need for increased circularity and valorisation of available resources. Chaff constitutes one of three main fractions obtained upon harvest of certain crops, during which it is generally discarded on the field. LÄS MER

  5. 4. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Virginia Tosi; [2021]
    Nyckelord :Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Sammanfattning : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

  7. 5. An assessment of the potential for using gasification technologies for thermal applications in Uganda’s small-scale agro-industries

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Job Mutyaba; [2014]
    Nyckelord :biomass gasification; agro waste to energy; thermal applications;

    Sammanfattning : Energy is one of the biggest costs of production in industries and Small scale industries in Uganda are faced with a big burden due to the high energy costs they incur in their operations. Due to the high costs associated with electricity and fossil fuels, biomass energy continues to supply the bulk (81%) of industrial energy demands. LÄS MER
