Abstract

Sewage water is a complex mixture in terms of chemical, biological, and physical characteristics. It is part of the most renewable wastewaters, while it should not be, at least in arid and semiarid countries. A trogonal problem of aridity, increasing population, and mismanagement of natural resources exists in many areas of the world, predominantly in the southern hemisphere and politically referred to as developing countries. Increasing population per se imposes the adoption of new strategies for handling wastewater including sewage water more efficiently, especially when combined with shortage of food resources. Green areas not only provide crops for food and fodder but also enrich the global atmosphere with oxygen. Plants also absorb oxides of carbon, nitrogen, and sulfur (COX, NX, and SX, respectively), thus cleaning the atmosphere and making it healthier. Subsequently, greening any area on earth by cultivating any kind of green cell must be of global concern, not neglected as a national issue.
