Cleaning of water bodies using coastal sea bin (CSB).

The rivers in Mumbai are highly polluted with plastic waste and these rivers end up in the Arabian Sea, which brings all this waste back to the land during high tides. This garbage keeps piling up on land and it is difficult to manage this waste. Plastic waste causes harm to wildlife, environment, and human beings. Therefore. it is decided to design a rectangular suspended sea bin with the non-return flaps, facing the waves. The floating garbage that is flowing along the waves will enter the cage through the flaps and thus get trapped. The waves will thus progress without any hinderance due to the cage openings on the rear side. A comprehensive study is done with the weight, center of gravity and metacentric height of a rectangular coastal sea bin (CSB) for different materials. Aluminum is considered as an ideal material for the case study as it is durable, light- weight and non-corrosive. A simulated 3D CSB model with the scale ratio of 1:12.5 is also prepared.•Plastic waste causes harm to wildlife, environment, and human beings•A rectangular cage type rectangular coastal see bin (CSB) is designed with the non-return flaps, facing the waves for plastic collection•A simulated 3D CSB model with the scale ratio of 1:12.5 is also prepared.
