  1. 1. Shit Matters! Assessing sociocultural barriers and opportunities for upscaling adoption of human faeces derived fertilizers in central Uganda

    Master-uppsats, Lunds universitet/LUCSUS

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

    Sammanfattning : 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. LÄS MER

    Sammanfattning : 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. 3. Treatment of faecal sludge from pit latrines and septic tanks using lime and urea : Pathogen die-off with respect to time of storage

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Emma Lindberg; Anna Rost; [2018]
    Nyckelord :faecal sludge; treatment; lime; urea; pathogen inactivation;

    Sammanfattning : The study was made at Lubigi sewage treatment plant in Kampala, Uganda, during February and March 2018. The aim of this master thesis was to treat faecal sludge with two different methods, urea and lime, to investigate the efficiency of the chemicals to inactivate pathogens and to estimate the feasibility and the costs of the treatment.

  5. 4. sSWOT-analysis of the introduction and usage of faecal sludge as fertiliser in agriculture in the Western Cape Province, South Africa

    Kandidat-uppsats, KTH/Industriell ekologi

    Författare :Felicia Frise; Anna Ringström; [2017]
    Nyckelord :;

    Sammanfattning : For future generations, securing nutrients and minimising the biochemical flows are significant challenges for humanity. Due to this, it is important to develop new phosphorous recovery methods from alternative sources to secure food production, reach sustainable development and circular economy. LÄS MER

  7. 5. Estimating the potential for resource recovery from productive sanitation in urban areas.

    Master-uppsats, KTH/Mark- och vattenteknik

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

    Sammanfattning : 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. LÄS MER
