          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.

          Marine pollution. Plastic waste inputs from land into the ocean.

          Plastic debris in the marine environment is widely documented, but the quantity of plastic entering the ocean from waste generated on land is unknown. By linking worldwide data on solid waste, population density, and economic status, we estimated the mass of land-based plastic waste entering the ocean. We calculate that 275 million metric tons (MT) of plastic waste was generated in 192 coastal countries in 2010, with 4.8 to 12.7 million MT entering the ocean. Population size and the quality of waste management systems largely determine which countries contribute the greatest mass of uncaptured waste available to become plastic marine debris. Without waste management infrastructure improvements, the cumulative quantity of plastic waste available to enter the ocean from land is predicted to increase by an order of magnitude by 2025.

            A comparison of plastic and plankton in the north Pacific central gyre.

            The potential for ingestion of plastic particles by open ocean filter feeders was assessed by measuring the relative abundance and mass of neustonic plastic and zooplankton in surface waters under the central atmospheric high-pressure cells of the North Pacific Ocean. Neuston samples were collected at 11 random sites, using a manta trawl lined with 333 u mesh. The abundance and mass of neustonic plastic was the largest recorded anywhere in the Pacific Ocean at 334271 pieces km2 and 5114 g km2, respectively. Plankton abundance was approximately five times higher than that of plastic, but the mass of plastic was approximately six times that of plankton. The most frequently sampled types of identifiable plastic were thin films, polypropylene/monofilament line and unidentified plastic, most of which were miscellaneous fragments. Cumulatively, these three types accounted for 99% of the total number of plastic pieces.
