Eco-friendly sanitation refers to waste management practices that minimize environmental impact while promoting public health. This approach often includes the use of composting toilets, which convert human waste into compost, reducing the need for water and preventing pollution. Additionally, eco-friendly sanitation systems may utilize biogas digesters to convert waste into renewable energy. These systems aim to reduce reliance on traditional sewage treatment, which can be costly and harmful to ecosystems. By implementing sustainable practices, communities can improve sanitation access while protecting natural resources. Eco-friendly sanitation is essential for achieving the United Nations' Sustainable Development Goals, particularly those related to clean water and sanitation.
