Blog: Food for Thought (and Not for Landfill)

Power Knot Ocean had a successful debut at Seatrade Cruise Global 2023, with Seaborne, SeaDream, Carnival Corp & plc, and other global cruise companies showing high interest in the technology. The biodigesters offer a sustainable solution that aligns with other companies' values, paving the way for a cleaner and greener future in the cruise industry.

Garbage disposals are found in over half the homes in the United States, but have been banned from municipalities across Canada. We dive into why they are banned and why biodigesters are the choice food waste solution of the second largest country in the world.

Ships contribute 20-70% of plastic pollution in the ocean. The Great Pacific Garbage Patch and Inaccessible Island reveal ships as primary polluters.

As we move closer to 2030, it’s time to evaluate just how far we’ve gone – and how much more work needs to be done to achieve this notable food waste reduction goal. 

In June 2022, Holland America’s Corp. Fleet Environmental Compliance Manager, Sanjay Bhatt, visited Power Knot’s headquarters in Silicon Valley, California to receive technical training on the LFC biodigester. We took the opportunity to learn from Sanjay about the use of biodigesters on cruise ships.

Atmospheric levels of the three main greenhouse gasses that cause climate change—carbon dioxide, methane, and nitrous oxide—all reached new record high values in 2021. Without further action to rein in these emissions, the planet faces a dramatic increase in risks including extreme weather, food and water shortages, and other crises. 

In early October 2022, Power Knot Ocean joined…

Over the past three years, Carnival Corp & plc installed nearly 600 food waste biodigesters across nine of their major cruise line brands. This significant investment in waste management technology was necessary to help Carnival Corporation meet MARPOL compliance and support its food waste management objectives. However, ships shouldn’t simply dump their food waste into the ocean for a number of reasons beyond the obvious negative impact on the environment and the risk of discharging plastics.

In early June, Power Knot Ocean attended Posidonia 2022, an international shipping exhibition which takes place every two years in Athens, Greece. In this blog, we review the top three things we learned at Posidonia and what they mean for the future of the waste and maritime industries.
