AI-powered food waste prevention for cruise ship galleys
You load before you sail and can't restock at sea, so galleys over-provision to be safe. Marine-grade hardware and Wave Filter technology deliver accurate waste data even as the ship moves, galley by galley, voyage by voyage. Crews use it to control food costs, hit environmental targets, and report compliance without the guesswork. The menu stays exactly as it is.
Running in 3,500+ locations across 90+ countries, at sea and ashore.

We’ve optimised portion control and quantity at the buffet station, making the food in smaller batches and refilling it more often. The food then arrives fresher and hotter to our guests which helps a lot with maintaining our high guest satisfaction scores.
