Eco-san, short for ecological sanitation, is a sustainable approach to managing human waste. It focuses on recycling nutrients from human excreta to improve soil fertility and reduce environmental pollution. Eco-san systems often use dry toilets that minimize water usage and promote composting, making them suitable for areas with limited water resources. This method not only helps in waste management but also supports agricultural practices by providing organic fertilizers. By closing the nutrient loop, eco-san contributes to healthier ecosystems and promotes sustainable living. It is particularly beneficial in rural areas and developing countries where sanitation infrastructure may be lacking.
