Dumping sewage sludge, industrial waste, human waste, etc. into the sea. Human waste has been dumped for a long time, but ocean dumping for industrial waste disposal has become problematic in terms of marine pollution, and is now subject to various regulations, such as the Waste Disposal and Cleaning Law and the Marine Pollution Prevention Law. Under these circumstances, the ocean dumping of sewage sludge, which has no place to be treated, is causing various problems. Ocean dumping of radioactive waste has also become problematic, and the trend is toward land disposal.

下水汚泥,産業廃棄物,糞尿などを海に投棄すること。糞尿の投棄は古くから行われているが,産業廃棄物の処理のための海洋投棄が,海洋の汚染の面から問題化して,廃棄物の処理及び清掃に関する法律,海洋汚染防止法など,各種の規制を受けるようになった。このような状況下で,処理の場所を失った下水汚泥の海洋投棄が種々の問題を引起している。また放射性廃棄物についても海洋投棄が問題視されてきており,陸地処分の方向に向っている。
