This SEI discussion brief assesses the adoption of biodigesters among livestock farmers in Bangladesh. The study finds that while small and mid-sized privately owned biodigesters provide health, environmental, and economic benefits, the government's policy goal of establishing collectively owned 'community' biodigesters for small-scale and landless farmers has not been realized due to a lack of social capital and group financing.

This fact sheet describes a sustainable sanitation pilot project implemented at the Tarumitra Bio-reserve and Ecology Centre in Patna, Bihar, India. The project, funded by the Swedish International Development Cooperation Agency (Sida) and implemented by the Water, Sanitation and Hygiene Institute (WASHi) and the Stockholm Environment Institute (SEI), established an ecological sanitation (ecosan) complex to provide an alternative to open defecation and demonstrate the agricultural benefits of reusing human excreta.

This 2006 report by the Stockholm Environment Institute examines urine diversion as a sustainable sanitation alternative to help meet the Millennium Development Goals (MDGs). It details the technical, organizational, and economic aspects of separating urine from faeces to enable nutrient recycling in agriculture, drawing heavily on Swedish municipal experiences and international case studies from West Africa, China, and El Salvador.

This market study, conducted in December 2020 by a consultant for the Unité de Coordination de la Gestion des déchets solides (UCG) under the Senegalese Ministry of Urbanism, Housing and Public Hygiene, analyzes the potential for organic waste valorization through composting in the Dakar and Thiès regions. The report identifies a significant market potential of approximately 426,503 agricultural producers, particularly in the Niayes zone, but notes that the sector is hindered by a total lack of local regulation, high production costs, and a strong preference for subsidized mineral fertilizers. It proposes a strategic action plan focusing on institutional regulation, financial incentives, and technical capacity building to transition from a linear to a circular economy.
