Carnival Corporation Installs Environmentally Innovative Food Waste Biodigesters

Carnival Corporation & plc  (logo)Carnival Corporation & plc today announced it has completed the installation of nearly 600 food waste biodigesters across its fleet in support of ongoing food waste management and reduction efforts as part of its overall commitment to environmental compliance.

The innovative technology has been added to ships from the company’s nine cruise line brands – Carnival Cruise Line, Princess Cruises, Holland America Line, Seabourn, P&O Cruises (Australia), Costa Cruises, AIDA Cruises, P&O Cruises (UK) and Cunard.

The biodigester technology uses a natural aerobic digestion process inside each machine to efficiently break down food waste utilizing a mix of beneficial microorganisms, enabling the systems to process anything that can be consumed by a human.

Able to perform automated digestion 24 hours per day, the biodigesters are strategically placed in key areas of the ship where food is processed, further improving onboard operations by making it easier and more efficient for crew members to manage and control food waste. 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 Corporation and its nine global cruise line brands have continued to expand the use of these systems across their fleets. 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 returns its final of 23 total ships to guest operations this month.

As Carnival Corporation’s entire fleet returns to operations this year, its full lineup of brands will continue to see benefits from improved food waste management as additional biodigesters come online, further strengthening environmental performance across the company’s global operations.
