The ban on plastic bags was one of the most important initiatives in Rajshahi's cleanliness campaign. Plastic bags are a major source of pollution in Bangladesh, and their ban has helped to reduce the amount of litter on the streets. The public awareness campaign about the importance of cleanliness has also effectively changed people's attitudes about littering. The campaign has taught people about the harmful effects of littering and how to keep their city clean. The increased investment in sanitation infrastructure has also helped to improve the cleanliness of Rajshahi. The city has built new sewage treatment plants and improved its garbage collection system.
