Greywater and blackwater: improving the compliance gap
|Shipboard wastewater discharges—particularly greywater and blackwater—are under increasing scrutiny due to their contribution to eutrophication, oxygen depletion, and the spread of pathogens. With enforcement uneven and older ships often lacking modern treatment capabilities, the sector is exploring how best to close the compliance gap. This webinar will evaluate technological advances and regulatory developments shaping the future of wastewater handling at sea.
Join us as we discuss
- Current regulatory requirements under MARPOL Annex IV and enforcement issues
- Differences between greywater and blackwater, and the specific risks each poses to marine ecosystems
- Challenges in retrofitting older tonnage with sewage treatment systems
- Advanced treatment options: membrane bioreactors, UV disinfection, and electrochemical systems
