What is the primary purpose of a Type I marine toilet?

The primary purpose of a Type I marine toilet is to treat sewage for discharge directly into the water. These toilets use a system that involves chemicals or biological processes to break down waste and reduce its environmental impact before releasing the treated effluent. This type of toilet is designed for use in saltwater or freshwater situations and is suitable for vessel operations where direct discharge is allowed, abiding by environmental regulations.

In contrast, other types of marine toilets, such as Type II, are designed with different functionalities regarding waste management, including the need for a holding tank or shore-based emptying systems. Thus, while they may serve important functions, they do not fulfill the same role as a Type I toilet.
