Sanitation solutions refer to methods and technologies designed to manage human waste and promote hygiene. These solutions aim to prevent the spread of diseases and protect the environment. Common examples include sewage treatment plants, composting toilets, and biogas systems, which help in safely disposing of waste and recycling nutrients. Effective sanitation solutions are crucial for public health, especially in densely populated areas. They contribute to cleaner water sources and improved living conditions. Organizations like the World Health Organization and UNICEF advocate for better sanitation practices to ensure that everyone has access to safe and hygienic facilities.
