The first ship for a new sustainable ship recycling operation in Germany arrived at the shipyard in Kiel, where the pilot project will continue in the coming weeks. A German startup called Leviathan is working with Germany Naval Yards to demonstrate their process to apply for EU approval.

Leviathan reports that it has spent more than 10 years developing sustainable recycling technologies for ships. The cutting is done with cold cutting technology. According to the company, trials on test objects have shown that clean cutting technology can reduce CO2 emissions during the scrapping process by a factor of 300. They have worked to streamline and mechanize the processes to be both safe and economical for ship recycling on an industrial scale.

The sustainable recycling process is now being applied for the first time on a 123-foot landing craft at the German Naval Yards facility using technologies developed by Leviathan. The 56 year old ship that HC Hagemann 1, had operated as a supply ship. She arrived at the Kiel shipyard on June 14th and today, June 17th, the 147 dwt vessel was lifted into position. According to EU regulations, cutting must be done on a solid surface to prevent hazardous materials from spilling into the ground.

“For German Naval Yards, which traditionally builds and converts ships, environmentally friendly recycling is a welcome new challenge that we are happy to take on,” says Sofien Lamiri, Chief Operating Officer at German Naval Yards.

Cutting work will begin on June 20th and is expected to last up to six weeks. As part of the unique project, the shipyard also offers artists the opportunity to reuse parts and materials from the ship for further processing or to transform them into works of art.

“This is an important milestone and now the performance of the ESG-compliant recycling process can be verified over the next few weeks,” said Karsten Schumacher, Managing Partner at Leviathan. After successful testing, companies will apply for approval under EU regulations.
