Carnival installs food waste biodigesters

Carnival Corporation has completed the installation of nearly 600 food waste biodigesters across its fleet in support of ongoing food waste management.

The innovative technology has been added to ships from the company’s nine cruise line brands.

The biodigester technology uses a natural aerobic digestion process inside each machine to efficiently break down food waste.

Able to perform automated digestion 24 hours per day, the biodigesters are strategically placed in key areas of the ship where food is processed.

Additionally, the machines capture non-food items or other materials accidentally mixed with food waste, providing an additional layer of protection for environmental compliance on each ship.

Since first piloting the technology in 2019, Carnival has continued to expand the use of these systems.

Most recently, the company’s namesake brand, Carnival Cruise Line, announced it is the first major cruise line to employ biodigesters across its entire fleet as the brand returned all 23 total ships to guest operations.
