Ecological sanitation

The term ecological sanitation (derived from ecological sanitation ) ecological, cycle-oriented systems for wastewater management and sanitation are summarized.

The introduction of these systems represents a paradigm shift in urban water management: faecal matter and domestic waste water are consistently regarded as recyclables, which recovered ( to the extent necessary: processed ) and can be recycled. This means that these systems are based on a consistent implementation of a stream - oriented circular economy. They offer promising alternatives to conventional systems, the disposal of wastewater. Ecosan systems enable a full or partial recycling of the nutrients contained in feces, urine and gray water as fertilizer in agriculture, an economical use of water with the greatest possible re-use, for example for agricultural irrigation, and a recovery of energy, for example by Anaerobic. A frequently advantageous source separation and concentration can be achieved for example by urine separation or the separation of black and gray water. Ultimately, the use of appropriate systems such as composting toilets and constructed wetlands also leads to a minimization of the environmental health impact of water and hence a fall appropriate water-related diseases.

A broader understanding of the ecosan concept also considers the collection and management of rain water, the provision of process water and the treatment and recycling of solid waste, the minimization of the energy demand for waste and wastewater treatment and the use of the present in the solid and liquid waste energy potential ( for example, as biogas). It is based so far on the requirements of sustainable development. This understanding is now widely recognized in the professional world and is currently being demonstrated already in numerous projects.
