Cruise Ship Live Load
Traditionally, cruise ships landed waste into conventional garbage bins. Waste was segregated into different categories depending on the type of garbage. Typically, a separate “wet” bin was supplied for food contaminated garbage, another one (or more) for dry, another for incinerator ash and glass, and one (or more) for metal/recyclables. For environmental reasons, garbage bins are not permitted to be left overnight on the cruise terminal piers. Garbage bins had to be removed once they were filled. This meant the bin transport added to the already heavy traffic load (tour buses, etc.) while the ships were in port. Because the majority of the ships called in Victoria in the evening, any increase in late night traffic, (particularly with heavy equipment) had a profound effect on the cruise industry’s relationship with the adjacent residential neighbourhood.
COST SAVING & ENVIRONMENTAL BENEFIT
Because Envirosystems maintains a close working relationship with our cruise partners, we learned of a pilot project underway in the Port of Miami where recyclables only were being transported by curtain-side trailers. Envirosystems promptly adopted the idea but moved it one step further to transport all waste streams. Our rational was very simple in that since the ships landed waste already palletized and segregated then it made better sense to load it direct to a trailer rather than commingle in a garbage bin. One live-load trailer holds the equivalent of three to five garbage bins. Utilizing the live-load trailers enabled Envirosystems to offer a compost option to the cruise ships whereby uncontaminated food scraps would be composted instead of being sent to the landfill. This was accomplished by utilizing insulated heavy duty sealed and leak-proof totes that could be stacked on the trailer. The compost program, long desired by the cruise lines, was not possible with a garbage bin system due to pier side transfer issues and odour. Because the trailers were sealed with the curtain system they are permitted to remain on the pier overnight.
The cruise ships aw a transport cost savings of approximately 30% on the first trailer and 50% on subsequent units. The trailers were held on the pier overnight so did not contribute to the late night noise and traffic volume. The trailers were moved and returned empty to the cruise terminal during normal daylight working hours. In addition to the traffic reduction and timing benefits, the environmental footprint of transporting the waste was reduced by a factor of four compared to bin transport.
