All refuse coming off cruise ships is considered international garbage, and must be incinerated. Local garbage (in Halifax at least) is composted, recycled or land filled. During cruise season, when there are several large ships in port, there is a veritable mountain of garbage coming ashore, which does not enter the domestic "waste stream."
2. Gulf Spray works alongside Silver Whisper at pier 20, also September 18.
LeGrow's Marine handles most of the debris, and mobilizes itssmall fleet to do the job. The garbage is removed on the offside of the ship (to avoid the possibility that passengers will be be offended by their own garbage!) and barged to shore, usually at pier 29, where it is then trucked to the incinerator.
