Themed collection Sanitation

This article provides a perspective on the reasons behind why we have not yet achieved sustainable sanitation for all, i.e. universal access to some form of improved toilet and sludge management services, and presents research needs and strategies for moving closer to this goal.

This study critically reviews literature and provides material flows of nitrogen, phosphorus, and carbon to determine the ability of existing sanitation technologies and strategies that can be deployed to safely recover resources and thus achieve multiple sustainable development goals.

The trash-excluding attachment (Excluder) can be connected to a custom vacuum (such as the Flexcrevator), a vacuum truck, or a sludge pump. The system allows the mechanized emptying of pit latrines with high levels of trash without manual “fishing”.

A novel treatment system for pit latrine faecal sludge; solar-dried sludge with captured leachate heat-treated in agriculture using waste-fired rocket stove.

Demonstration of an electrochemical toilet wastewater treatment and disinfection technology at the scale of an apartment building and translation of the system into a commercial product.

CFD model evaluated toilet container lined with laminated hydrophobic membrane. Model predicted drying accurately for cm- to m-scale systems. Model predicted performance of laminate-lined toilet for developing countries.

Integrated approach to assess the sustainability of on-site sanitation systems.

A liquid phase method to treat faecal odourants at source using membrane technology, consequently encouraging facility and water reuse acceptance.

Semi-structured interviews with females and community members identified the greatest number of unique and most priorities in resource-limited communities.

Self-contained toilet wastewater treatment system prototypes based on electrochemical oxidation of feces and urine using bi-layered semiconductor anodes ([Bi₂O₃]_z[TiO₂]_1−z/Ir_xTa_yO₂/Ti) have been designed, constructed, and implemented in regions where access to proper and sufficient sanitation is limited.

Energy recovery from bio-oil was feasible when pit latrine sludge with a water content of ≤∼55% was the feedstock.

Viruses represent major disease transmitting agents carried by human excreta and animal manure.

This paper discusses various institutional and social conflicts that detrimentally affected the implementation of a vacuum sewer in South Africa.

This article demonstrates the application of a screw auger to separate fresh urine and faeces in a household scale sanitation system.

There is a trend towards participation of users in the design of appropriate sanitation facilities for low-income countries.

Consolidating findings from research managed by 5 international consortia considering the factors that influence the development and effectiveness of sanitation service chains in 9 cities of Francophone and Anglophone Africa.

The cost-effectiveness of two different urine-collection programs in South Africa are modelled over a range of parameters and are interpreted from the perspective of both the municipality and the community.

This paper reports on the pee power urinal field trials, which are using microbial fuel cells for internal lighting.

This paper presents a methodology to support the implementation of Faecal Sludge Management services in informal settlements in Lusaka, The Republic of Zambia.
