Garbage classification on board ships is also very strict. So what is garbage classification at sea like?

It is said that a cruise ship is a moving castle, naturally supported by a complex and huge life system.

Taking the Quantum of the Seas as an example, it has a displacement of 167,000, a passenger capacity of 4,180, and a crew of nearly 1,600. To ensure the normal diet and daily life of so many people, the garbage generated every day may be larger than that in your community. It adds up to much more.

The sea cannot take away sorrow, and nature cannot digest so much garbage. What’s more, there are many lovely marine creatures that need a beautiful home just like us.

So as early as 1954, the British government organized a diplomatic conference on the prevention of marine pollution and adopted the 1954 International Convention for the Prevention of Oil Pollution from the Sea.

? Later, everyone discovered that the only type of pollution at sea was oil, so they met again in 1973 and adopted a more comprehensive "International Convention for the Prevention of Pollution from Ships."

? After continuous revisions, the latest "Convention" stipulates that ships should classify garbage into categories A to K, with 11 categories. Part 1: A. Plastics, B. Food waste, C. Domestic waste, D. Edible oil, E. Incinerator ash, F. Operational waste, G. Animal carcasses, H. Fishing gear, I. Electronic waste things. Part 2: J. Cargo residues (non-harmful substances to the marine environment), K. Cargo residues (materials harmful to the marine environment). Among them, categories J and K are applicable to ships carrying solid bulk cargo, and categories A to I are applicable to all ships. In other words, for cruise ships carrying passengers, when dealing with garbage, it needs to be divided into nine categories.
