  1. 1. The potential use of black soldier fly larvae residue as a fertilizer

    Master-uppsats, SLU/Dept. of Agricultural Biosystems and Techology

    Författare :An-Marthe Ingelaere; [2023]
    Nyckelord :organic waste; fertilizer; black soldier fly; residue; physico-chemical characteristics; sub-Saharan Africa; socio-economic constraints;

    Sammanfattning : In sub-Saharan Africa (SSA), the primary constraint of agriculture productivity has consistently been ascribed to soil fertility. A common approach to improve soil fertility is the use of fertilizers, both organic and inorganic. Though recently interest is increasing in the use of newer alternatives like biostimulants. LÄS MER

  3. 2. Production of filamentous fungal biomass on waste-derived volatile fatty acids for ruminant feed supplementation and it's in vitro digestion analysis

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

    Författare :Mohammadali Bouzarjomehr; [2022]
    Nyckelord :VFAs volatile-fatty-acids ; Fungi production; Feed production.; Fermentation processes; Aspergillus oryzae; A. oryzae fungal biomass; Sustainability; Rumen fluids; Evaluation of the digestibility of the produced fungal biomass; TT method analysis; Gas production method; Nylon bag method analysis;

    Sammanfattning : Single cell proteins such as that of edible filamentous fungal biomass are considered as a promising sustainable source of animal feed supplementation. Filamentous fungi can be cultivated on different organic substrates including volatile fatty acids (VFAs) such as acetic, propionic, and butyric acids. LÄS MER

  4. 3. Storage of poultry manure in containers : changes in physiochemical parameters and survival of intestinal bacteria

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Homayoon Davam; [2022]
    Nyckelord :Enterobacteriaceae; Salmonella; composting; straw; litter decontamination; chicken manure;

    Sammanfattning : High nutrient content of chicken litter has made it one of the best organic fertilizers for agricultural land. However, reusing poultry litter in agriculture can be associated with food-borne pathogens such as E.coli, Salmonella and Campylobacter. LÄS MER

  5. 4. Potential of waste-derived VFAs-bearing effluents as an external carbon source for MBBR denitrification of domestic wastewater

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

    Författare :Seyed Reza Manafi Khosroshahi; [2022]
    Nyckelord :Volatile fatty acids; Denitrification; Wastewater treatment; Biological nutrient removal; Nitrate removal; Electron accepter; Carbon source; Electron doner; Moving bed biofilm reactor; Nanofiltration; VFA concentration; Discharge standards; Carriers; acclimatization; VFAs; MMBR; NF; WWTP; BNR;

    Sammanfattning : In conventional wastewater treatment plants, methanol, ethanol, and acetate are used as carbon source for the denitrification process in the biological nutrient removal. However, growing concern regarding economical costs and carbon footprints from the fossil-based production of these chemicals have forced the companies to look for other alternatives. LÄS MER

  7. 5. Gains N Greens

    M1-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Jakob Frank; Tom Hjälmefjord; [2020]
    Nyckelord :aquaponics; sustainability; food production; environment; akvaponik; hållbarhet; matproduktion; miljö;

    Sammanfattning : At present, it is focused either on aquaculture or agriculture. Those who focus on aquaculture or Recirculating Aquaponics System (RAS) receive a by-product of ammonia, which is then cleaned and the water either goes back to the fish or it is not cleaned at all and as they do in the salmon farms for example they let it sink to the bottom which creates eutrophication and major problems among the marine.
