What should never be done with plastic waste on a ship?

Throwing plastic waste overboard is never acceptable due to the severe environmental impact it causes. Marine pollution is a critical issue, and plastics can harm marine life and ecosystems. They do not biodegrade and can persist in the ocean for hundreds of years, leading to consumption by wildlife, which can result in injury or death to various species.

The other options involve more responsible management of plastic waste. Recyclable materials can be processed appropriately rather than contributing to pollution. Storing plastic waste for later disposal ensures that it can be managed properly at designated facilities, and incineration is another method that some ships may use, provided they follow environmental regulations. These practices are in line with maritime laws and regulations aimed at reducing the impact of waste on the marine environment.
