Did you know there’s a hotel in Kawasaki City, Japan that creates hydrogen from waste plastics to supply about 30% of its energy needs?

Pioneered by Japanese multinational conglomerate Toshiba, the hydrogen hotel, formally known as the Kawasaki King Skyfront Tokyu REI Hotel, was opened in June 2018.

In the first year after its opening, the hotel ran a test in which it recycles even the amenities used in hotel rooms, such as toothbrushes and hair combs, as feedstocks for hydrogen production.
