Excreta and Wastewater Management
2.6 billion people worldwide are currently living without
adequate access to sanitation. The
development of innovative engineering solutions for collection, transport,
treatment, and resource recovery is essential to fulfill the sanitation needs
of urban areas in low- and middle-income countries.
Sandec’s current research in Excreta and Wastewater
Management addresses three main challenges: I. Optimization of Treatment
Technologies, II. Innovation in Resource Recovery, and III. Methods for
Sustainable Systems Level Implementation.
Faecal Sludge Mangement: Systems Approach for Implementation
and Operation, is being edited by Sandec and UNESCO-IHE, and will be published
in June 2013 by IWA
Research projects:
Faecal Management Enterprises (FaME) - Develop resource recovery oriented faecal sludge management solutions through value chain optimization in Sub-Saharan Africa.
Resource Recovery & Reuse (RRR)
- Identify and scale-up promising business models for safe resource
recovery of nutrients, water, and energy from liquid and solid waste, in
Africa, Asia and Latin America.
Partnership for Urban
Resource Recovery – Comprehensive Management of Biosolids from
Wastewater and Faecal Sludge Treatment (PURR) - A new research
project to evaluate options for the co-treatment and resource recovery
of biosolids from wastewater and faecal sludge treatment in five cities
in Vietnam.
Collaborative partnership in faecal sludge management in Burkina-Faso
- Develop a faecal sludge management scheme, and strengthen staff
capacity for the operation and maintenance of the wastewater and faecal
sludge infrastructure in Burkina Faso.
De Déchets à Ressources (DAR) - From waste to resource - Research on faecal sludge drying beds and faecal sludge enduse in Dakar, Senegal
Nutrient harvesting in South Africa (VUNA)
- Recover nutrients from urine in small decentralized reactors, develop
a dry sanitation system which is affordable for the poor, promote
entrepreneurship and reduce pollution of water resources.
Nutrient Valorization from Urine in Nepal (STUN) - Examine various possibilities to recover nutrients from source-separated urine in order to produce fertilizer.
