Ecological Sanitation
Environment
Improved disposal of human waste protects the quality of drinking water sources. At present, each year more than 200 million tonnes of human waste – and vast quantities of waste water and solid waste – go uncollected and untreated around the world, fouling the environment and exposing millions of people to disease and squalor.
Moreover, reusing waste has many benefits. Reuse of treated waste for agriculture is an environmental, as well as economic, gain.
