===Introduction===
Human faeces and urine contain a large amount of nutrients, which can be used in agriculture for crop irrigation, for fish aquaculture, or aquatic vegetable pond fertilization. In many cultures, for example the Chinese, the idea that 'waste is too valuable to waste' is well known, and <span class="plainlinks">[http://www.bestpills4weightloss.com/<span style="color:black;font-weight:normal; text-decoration:none!important;background:none!important; text-decoration:none;">best weight loss pills</span>] has been practiced for centuries. In many other cultures however, sanitation products are hardly used for productive use, although interest is growing. Especially the 'Ecological Sanitation (EcoSan)' movement (also called 'sustainable sanitation') has led to more interest in this field. When sanitation products are reused, great care has to be given to dealing with the potential health and environmental risks of human waste products.
==Description of =Approach===
Ecosan is not so much a technology as a way of thinking. It views (treated) human excreta and greywater as valuable resources that can be put to productive use. In that sense, it requires a change of thinking about waste issues in terms of recycling and closing material loops, where waste is no longer regarded as waste but as a resource.
===Potential===
In most conventional wastewater and sanitation systems, large amounts of valuable nutrients are wasted. This can lead to reduced soil fertility and/or the need to apply (and buy) chemical fertilizers. Therefore, applying ecological sanitation has a very large potential.
==Country =Field Experiences===
EcoSan is practiced in most world regions. EcoSanRes has a [http://www.ecosanres.org/map/index.html World Map] with EcoSan initiatives.
