Socio-Cultural Acceptability of Urine Diverted Composting Toilets: A Review of Literature for Possible Adoption in Peri-Urban Areas as a Sustainable Sanitation Solution

The improvements of strategies and treatment options adapted to conditions prevailing in developing countries have long been neglected as regards faecal sludge (FS) the by-products of on-site sanitation installations. In recent years, an encouraging number of initiatives towards improved FS management, including appropriate FS treatment schemes, have been developed, particularly in Nepal, Thailand, Vietnam and Bangladesh. These initiatives assist urban and peri-urban dwellers and authorities to overcome the challenges of undifferentiating and uncontrolled disposal of faecal sludge into drains, canals and onto open spaces, thus producing a "faecal film" in urban areas that impair public health and cause pollution. Though people around the world are buying, or being offered with, pit latrines, shared toilets, or other enhanced sanitation solutions, this is vital to reduce transmission of diseases; questions arise about how to deal with the fecal sludge management. Sanitation is the hygienic way of upholding health through avoidance of human contact with the hazards of wastes as well as the treatment and proper disposal of sewage or wastewater. Waterborne diseases are the single most vital cause of death and illness in developing countries. The understanding of social issues is paramount introducing an alternative sanitation system. Although treating excreta is a universal aspect of human existence, the topic has not been rigorously investigated by social scientists identifying three cultural influences that affect the acceptance (or rejection) of an alternative sanitation system: psychology, religion and gender. Composting literature review focuses on increasing awareness and developing good understanding of composting toilets as an alternative urban sanitation technology.
