Film actor Akshay kumar has launched an advertisement campaign on twin pit toilet technology for the Swachh Bharat Mission (Grameen) in New Delhi on May 27, 2018. The ad campaign focuses on promoting the twin pit toilet technology in rural India. The actor appealed everybody to spread the awareness on the issue and make the cleanliness drive more effective. The twin pit toilet technology is an Indian invention that collects defecation for a period of five years and then it turns into valuable organic compost. This decomposed waste is safe to handle and rich in NPK (nitrogen, phosphorus, potassium) nutrients which makes it ideal for use in agriculture. The technology is also recommended by the World Health Organization (WHO).
