Limit, cease or prohibit discharge of solid waste overboard from vessels
Overall effectiveness category No evidence found (no assessment)

Background information and definitions
Commercial and recreational vessels can generate large amounts of garbage and solid waste (Butt 2007). Wastes discharged overboard can pollute marine and freshwater environments through the introduction of bacteria, excess nutrients, toxic substances, solid particles, and litter. Limiting, ceasing or prohibiting the discharge of waste overboard from vessels in an area may reduce or stop the source of pollution, and therefore reduce associated impacts on marine and freshwater mammals. However, solid waste can accumulate and persist in aquatic environments for a long time due to slow degradation (Pham et al. 2014, Andrady 2015), therefore this intervention alone may not be sufficient.
For an intervention related to the discharge of waste effluents, see Limit, cease or prohibit discharge of waste effluents overboard from vessels.
