  • Sustainability through conscious choice of materials and application of „ecosan” technique. “Ecological Sanitation” is a new paradigm in municipal water management, which considers waste water from buildings as a resource that can be recovered, treated if necessary and ultimately reused. Ecosan systems allow the nutrients contained in waste water to be recovered and used again in agriculture, therefore improving soil fertility and grown agricultural products, while minimising the depletion and pollution of fresh water resources. It is also possible to generate biogas systems into renewable energy
