Plastic has been mixed with other waste and it has taken a solid shape inside a box culvert of Gopibagh in the capital's Segunbagicha.
Dhaka South City Corporation (DSCC) on Saturday morning started removing the solid waste from the culvert.
DSCC's Chief Waste Management Officer Md Badrul Amin inspected the waste removal activities at noon.
During the visit, he said, "Over many years, various types of plastics have accumulated into solid waste. We need to clean up this waste regularly. Besides, people need to be more aware of throwing plastic everywhere.
