For example, ClevelandCliffs, Lurgi, and LTV Steel built a 400,000 tons/year Circored direct reduction plant in Trinidad that used hydrogen from a steam reformer as its reductant and energy source. The plant was started up in 1999, but the fluidized bed reactor had numerous problems and it produced only about 150,000 tons by the time it was shut down in 2001.
Another plant with a similar scale, the FASTMET No. 2, was delivered to the same site in 2005. The demonstration plant constructed at Kobe Steel's Kakogawa Works in the 1990s is still at work, recycling reduced iron from oredust generated in the ironworks, and contributing to resource reduction (Fig. 4).

Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BFBOF and ScrapEAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.
