Making the most of waste water

摘要

New cruise ships have the latest technology to recycle, water, incinerate waste and crush glass. Cruise lines are also working to try and minimise the amount of packaging they use, like crates and pallets that come onboard their vessels. One means of cutting down on emissions is by using scrubbing technology which has been trialled on Holland America Line's Zaandam by Hamworthy Krystallon. The system aims to remove 98% of sulphur and almost all particulate matter from a 3.5% sulphur residual fuel. However, one problem with the use of scrubbers is the wastewater criteria. Although there are International Maritime Organization (IMO) wastewater regulations, many states have introduced their own requirements so there is a lack of conformity internationally.
