How LFC biodigesters can tackle Europe’s LNG discharge dilemma
Over 60 LNG tanks are currently stuck at the port, unable to offload their natural gas and organic waste. The LFC biodigester helps LNG tankers comply with strict MARPOL rule and regulations for food waste.

How Ships are Fueling the Global Plastic Pollution Crisis
Ships contribute 20-70% of plastic pollution in the ocean. The Great Pacific Garbage Patch and Inaccessible Island reveal ships as primary polluters.

Nearly 600 biodigesters deployed across cruise fleet
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.

Why Carnival installed 600 food waste biodigesters
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.

How improper food waste management leads to microplastics in the ocean
When a single-use plastic bag from the grocery store or plastic straw from a morning coffee doesn’t make it to the recycling center, it is discarded. Only 9% of plastic waste gets recycled. Most of the plastic waste ends up in the ocean or the landfill. When it ends up in the ocean, the plastic slowly breaks down into microplastics–a big small problem that is causing unknown and adverse effects on the environment.

The Future of Maritime Waste at Posidonia
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.
