    Co-composting of organic waste and faecal sludge

    • Decentralised Co-Digestion of Faecal Sludge with Organic Solid Waste. Case Study in Maseru, Lesotho C. Müller (2009). This study evaluates the biogas plants installed in Maseru, Lesotho, by TED-Borda. These biogas plants treat mainly human faeces, but also kitchen and garden waste and animal manure.[4.1MB]
    • Co-Composting Reduces Helminth Eggs in Faecal Sludge K. Gallizzi (2003). Results of monitoring the faecal sludge/solid waste pilot co-composting scheme at Buobai, Kumasi (Ghana) for helminth egg removal. Field report.[593KB]
    • Nitrogen in Co-compost and other chemical compost analyses M. Tanner (2003). Results of monitoring the faecal sludge/solid waste pilot co-composting scheme at Buobai, Kumasi (Ghana) for physico-chemical parameters, notably nitrogen. Field report. [739KB]
    • Co-composting of Faecal Sludge and Municipal Organic Waste M. Strauss, S. Drescher, C. Zurbrügg, A. Montangero, O. Cofie, P. Drechsel (2003). The review sets out to describe the resource potential of faecal sludge (FS) and organic municipal solid waste (MSW); introduces meaningful characteristics of FS and MSW, and describes options for FS and organic MSW treatment, of which the combined composting (co-composting) constitutes one. The relevant process design and operational parameters for composting and co-composting are discussed. The documents also reports on cases and practices as retrieved from published and grey literature. Open questions are identified and proposals for further field research given.[1.2MB]

    Market demand for compost from organic waste

    Organic matter from landfills

    • Benefits and Risk of the Use of Organic Matter from Asmara Landfill in Agriculture S. Drescher, B. Abraha, Dr. W. Ogbazghi, Dr. M. Tesfai, S. Mehari, T. Kubrom (2004). This workshop report contains the core findings of the study presented to an audience of stakeholders and decision-makers in Asmara. The study comprises technical and socio-economic aspects. It presents the role of visible pollutants, heavy metal content and nutrient content of the material as well as the perceptions of farmers who use the material. The report shows the responses of different stakeholders on the issue and an outlook on further activities. [1.3MB]

    Community-based involvement in solid waste management

    • Determinants of resilience in community‐led waste managementCh. Zurbrügg, S. Rothenberger (2013). The study identifies and analyses the driving forces, factors of sustainability as well as internal and external factors which influence failure or success of solid waste community‐based initiatives in India.[209KB]
    • Enhancing Community Motivation and Participation in Solid Waste Management C. Zurbrügg, R. Ahmed (1999). Sandec News No. 4 - This Sandec News article describes a pilot project in Shah Rasool Colony a low income community in Karachi Pakistan where the community initiated a community based primary collection scheme for their neighborhood.[367KB]
    • Informing, Educating and Motivating Community Members C. Zurbrügg, R. Ahmed (1998). This paper was presented at the Third Swedish Landfill Research Symposia in October 1998 in Lulea, Sweden. It describes a pilot project undertaken in Shah Rasool Colony a low income community in Karachi Pakistan. The project involved an information, education campaign to motivate the community members to initiate a primary waste collection scheme, managed by the community itself.[172KB]
