Annex IV (sewage)

Annex IV refers to regulations under the International Convention for the Prevention of Pollution from Ships (MARPOL), specifically focusing on sewage discharges from ships. It sets standards for how and where sewage can be disposed of, aiming to protect marine environments from pollution. Ships are required to have treatment systems that process sewage before disposal, and they can only discharge treated sewage in designated areas, ensuring the health of marine ecosystems and coastal communities. The regulations help mitigate the environmental impact of maritime operations, promoting cleaner oceans and safer marine life.
