Bangladesh is a riverine country. Although the transport system has significantly developed in the past few decades, still water transport remained one of the major mediums of transportation for passengers and transporting goods across the country. Every day numerous water vehicles transporting passengers and goods within the inland water-way of our country and among the peoples living by the places nearby river; launch is one of the most reliable media of transport. It is more preferable than any other means due to comfort and affordability. Every day around two lac people travels from one division to another via major launch routes of our country and millions in other inter-district/division local launces. Thus a massive amount of waste generates (which includes food waste, human sludge, oil, and others) during these trips and those became one of the major sources of pollution of our rivers.
