At its peak, Cardiff's port area, known as Tiger Bay, became the busiest port in the world and – for some time – the world's most important coal port. In the years leading up to the First World War, more than 10 million tonnes of coal was exported annually from Cardiff Docks. In 1907, Cardiff's Coal Exchange was the first host to a business deal for a million pounds Sterling. The high demand for Welsh coal and specifically Welsh artificial fuel, named Patent Fuel, is shown by the numerous factories producing this fuel, with the same recipe, in the region of Cardiff. Most well known factories were the Star Patent fuel Co., the Crown Patent fuel, the Cardiff Patent fuel etc. After a period of decline, due to low demand on coal, Cardiff's port has started to grow again – over 3 million tonnes of cargo passed through the docks in 2007.
