Power Knot and MLS Mare GmbH Address Food Waste on Marine Ships

March 26, 2025

FREMONT, CA —  Power Knot Ocean, the market leader for onboard organic waste management solutions in the marine environment, announced today that it has engaged MLS Mare GmbH to bring sustainable solutions for food waste to the maritime industry. MLS Mare is a trusted provider of technical solutions for shipboard hospitality services, specializing in laundry and galley equipment, including systems to dispose of food waste.

The LFC biodigester is an advanced food waste management system that utilizes aerobic digestion to break down organic waste into water. By eliminating the need for traditional waste disposal methods, it significantly reduces operational costs and environmental impact. 

The LFC biodigester is typically installed in galleys or garbage rooms on vessels, enabling seamless waste processing. Available in nine sizes, these units can process between 10 kg (20 lb) and 6000 kg (13,200 lb) of food waste per day, providing scalable solutions to meet diverse operational needs. The resulting greywater can be discharged or treated through the ship’s sewage treatment plant.

“Our partnership with MLS Mare marks a significant step in tackling food waste at sea. The LFC biodigester provides a sustainable, cost-effective solution that not only reduces waste but also helps ships comply with environmental regulations. Together, we are making maritime operations cleaner and more efficient,” Iain Milnes, President of Power Knot.
