    University essay from Lunds universitet/LUCSUS

    Author : Elina Persson; Therese Hågerup; [2018]
    Keywords : nutrient recovered faecal sludge; soil infertility; sociocultural norms; IBM-WASH; diffusion of innovations; Uganda; sustainability science; Social Sciences;

    Abstract : Nutrient recovered faecal sludge is a novel alternative fertilizer product, and is proposed to be promoted in places where improvement in sanitation management is needed, for example in Uganda’s capital Kampala. However, Uganda and most of Africa is perceived as a faecofobic area, i.e. READ MORE

  2. 17. Comparison of anaerobic sludge granules from different wastewater plants with respect to granule size, substrate degradation and methanogenic community

    University essay from SLU/Department of Molecular Sciences

    Author : Jonathan Andrén; [2018]
    Keywords : anaerobic digestion; granule; UASB; EGSB; VFA; methanogen; acetoclastic; hydrogenotrophic; acetogenic; mcrA; ; T-RFLP; methanosarcina; methanosaeta;

    Abstract : Within the objective to replace fossil fuel with sustainable sources there is a growing pressure to advance such development. Anaerobic digestion (AD) is beneficial not only as a waste management technology, but also to recycle organic waste into methane which can be used for heating, production of electricity or vehicle fuel.

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Gabrielle Joly; [2018]
    Keywords : Review; case studies; food waste; faecal sludge; co-digestion; low-tech system; cost-benefit analysis CBA ; Etat de l’art; études de cas; déchets alimentaires; boues de vidange; co-traitement; système low-tech; analyse coûts-bénéfices; Granskning; fallstudier; livsmedelsavfall; fekalslam; sambehandling; lågteknologiskt system; kostnads-nyttoanalys;

    Abstract : Ghana as a rapidly growing and urbanizing middle-income country is facing a number of challenges, including (1) implementing a sanitary, environmental-friendly, and economically-sound waste management system; (2) increasing its agricultural productivity in a sustainable way to meet the growing domestic food demand; and (3) providing livelihood opportunities in both rural and urban areas. Using the black soldier fly (BSF), a particularly beneficial insect, to locally and cost-effectively valorise abundant, high-impacting, and nutrient rich organic waste streams, such as food waste (FW) and faecal sludge (FS), into affordable and sustainable farming inputs like organic fertilizer and animal feed products, could tackle all these challenges at the same time.

  4. 19. Jämförelse av två olika uppföljningsmetoder av miljöhänsyn hos Norra Skogsägarna

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Julia Bergström; Lisa Renman; [2018]
    Keywords : drivning; miljöhänsyn; körskador; uppföljning; planering;

    Abstract : Miljöhänsyn vid skogliga åtgärder har den senaste tiden varit en aktuell fråga inom skogsbruket. God miljöhänsyn vid avverkning minskar risken att negativt påverka omkringliggande miljöer i form av körskador som kan leda till exempelvis kvicksilverutlakning, tillväxtförluster och ökad slamtransport.

  5. 20. Feasibility study for producing and using biogas in Chisinau, Moldova

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Johanna Alander; Adam Nylin; [2018]
    Keywords : Biogas; Biofertilizer; Biomethane; Potential; Feasibility; Chisinau; Moldova; Sustainable cities;

    Abstract : More and more people live in cities, cities that both present opportunities, in terms of potential sustainable growth and challenges, for example regarding insufficient infrastructure and waste management. There are several examples on initiatives to make cities reach their sustainability potential; one is to turn municipal organic waste, MOW, and sewage sludge into biogas and use it to produce electricity and/or heat or to upgrade it to biomethane and use it as a fuel in for example public transport or feed it to a gas grid.
