This Japanese sightseeing train runs on leftover ramen broth

In Japan, servings can be generous when it comes to ramen, the traditional broth-based dish with noodles, pork slices and fermented eggs, characterized by the famous fifth taste, umami. Although it's frowned upon in Japanese culture not to finish your plate, that's not always easy when the bowl is way too big. But now, Japan seems to have found an innovative solution to stop wasting leftover ramen...

In Miyazaki Prefecture, on the southern island of Kyushu, an old railroad line, the Takachiho Amaterasu Railway, takes visitors on a voyage of discovery through the lush green scenery of a peaceful and unspoiled Japan. The railway line is famous in the country for its passage over Japan's highest railway bridge. Anyone with a fear of heights might want to give it a miss!

The Amaterasu Railway stopped operating passenger services following damage caused by a typhoon in 2005, before a section was reopened as a tourist attraction, devoted entirely to contemplating the landscape during a 30-minute, 5-kilometer trip. The railway runs on a mixture of canola and sesame oil, supplemented with leftover ramen broth collected from various restaurants. Leftover oil from unfinished rice dishes is also used to power the train. In other words, there's not a fossil fuel in sight!

The sightseeing train is not the first guinea pig to test out this biofuel. Since 2021, this biofuel concoction, formulated by the logistics firm Nishida Shoun, has been used to power some of its fleet of almost 200 trucks.

However, while this solution is a great initiative for the planet, unfortunately, it cannot be used to power other, larger Japanese trains. Biodiesel has a very short shelf life. Moreover, filters need to be changed regularly.

This approach is reminiscent of another biofuel that drives the vaporetto water buses in Venice. Less glamorous than the smell of ramen, it is again used cooking oil that allows these boats to travel up the Grand Canal. Venetian restaurant owners put aside the precious liquid to help the vaporettos reduce their polluting emissions by 15% to 40%.

Similarly, in France, the national airline Air France has already managed to fly a plane using a sustainable fuel, composed of cooking oil, among other things. And just like in Japan, a small tourist train in Trojan-les-Bains, in the western Charente-Maritime region, also runs on used cooking oil. – AFP Relaxnews
