    Author : Martina Lundin; [2017]
    Keywords : dioxiner; dioxinliknande polyklorerade bifenyler; ekologiska ägg; persistenta organiska föroreningar; dl-PCB; PCDD; PCDF; TCDD;

    Abstract : Livsmedelsverket utförde en studie 2003 med syfte att undersöka halter av dioxiner och dioxinliknande Polyklorerade Bifenyler (PCB) i ekologiska och konventionella ägg. Förhöjda halter av dioxiner och dioxinliknande PCB (dl-PCB) påträffades i ekologiska ägg och gemensamt för de ägg med förhöjda halter var att värphönsen utfodrats med en fodertyp som innehöll fiskmjöl.

  3. 3. Biofloc technology : a new concept to produce feed to Swedish aquaculture

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Lovisa Granberg; [2016]
    Keywords : microbial protein; tilapia; shrimp; feed; environment;

To provide the fish with feed that is not a load on the environment the use of microbes as feed either filtrated directly from the water or recovered to become protein meal is very promising. Biofloc technology (BFT) is one method with filtration directly from water. READ MORE

  4. 4. Fodder yeast and biogas production: A fruitful symbiosis? : optimization of a single-cell protein process and examination of its impact on biogas output

    University essay from SLU/Dept. of Microbiology

    Author : Jonas Ohlsson; [2016]
    Keywords : fodder yeast; biogas; nutrient recycling; Wickerhamomyces anomalus; Pichia kudriavzevii; Blastobotrys adeninivorans;

    Abstract : Due to a growing world population and strained wild fish stocks, aquaculture is expected to provide a large part of the increased global demand for animal protein, as the majority of wild fish stocks are already being fished at or above their sustainable capacity. However, fish feed often contains a significant amount of fish meal, produced from wild-caught fish. READ MORE

    Author : Daniel Isaac Waya Ddiba; [2016]
    Keywords : Sanitation; Organic solid waste; Resource recovery; Waste reuse; Modelling; Developing countries;

    Abstract : To-date, sanitation has mainly been approached from a public and environmental health perspective and this implies that excreta and other organic waste streams are seen not only as a hazard to quickly get rid of but also as a very costly menace to manage. However, looking at sanitation management from a resource recovery perspective provides an avenue for solutions with multiple co-benefits. READ MORE
