Ecosan concept with material flow separation, treatment and reuse
Closing cycles in sanitation (poster from EcoSanRes program, 2005)
Close loops (in French), poster of the NRO CREPA in 2005 - example with urine separation toilets

The English term ecosan (derived from eco logical san itation ) encompasses ecological, cycle-oriented systems for wastewater management and sanitation. There are on the one hand, the waste water -based process of new sanitary systems , on the other hand wastewater-free process, which are mainly used in the international development.

The introduction of these systems means a paradigm shift in urban water management : faeces and domestic wastewater are viewed as valuable materials that can be recovered (if necessary: ​​treated) and recycled. These systems are thus based on the implementation of a material flow-oriented circular economy . They offer alternatives to conventional wastewater disposal systems . Ecosan systems enable complete or partial recycling of the nutrients contained in faeces, urine and gray water as fertilizer in agriculture, economical use of water with the greatest possible reuse, e.g. for agricultural irrigation , and recovery of energy e.g. through anaerobic technology . A frequently advantageous separation and concentration of material flows can be achieved, for example, by separating urine or separating black and gray water. Ultimately, the use of appropriate systems such as B. compost toilets , plant -based sewage treatment systems, urine separation toilets (also called urine-separating dry toilets ) also to a minimization of the environmental pollution of the waters and thus to a decrease in corresponding water-related diseases .

A broader understanding of the ecological sanitation concept also takes into account the collection and management of rainwater, provision of process water and the treatment and recycling of solid waste contained to minimize the energy required for waste and wastewater treatment and use of the solid and liquid waste Energy potential (e.g. as biogas ). In this respect, it is based on the requirements of sustainable development . This understanding is now widely recognized in the professional world and is currently being demonstrated in numerous projects. Ecosan , for example, has been an important topic in India for almost 15 years. The Innovative Ecological Sanitation Network India was founded there in 2004 , which has implemented a series of pilot and demonstration projects and also actively supports the subject areas of knowledge management and training.
