Jakarta is the capital of Indonesia. What many don’t know is that the Jakarta metropolitan area, also called Jabodetabek, is the second largest urban agglomeration in the world after Tokyo, with about 30 million inhabitants on an area smaller than the Greater London area. And the population is continuing to grow by around 3.6% per year. The infrastructure, however, is lagging behind this trend. There is neither an underground nor ring roads, and the average speed during rush hour is less than 15 km/h. But there is a solution in sight: the Indonesian government has launched a gigantic infrastructure programme. HeidelbergCement is the leading supplier of building materials in Jakarta. The Group’s largest cement production site is located in the metropolitan area. From mid-2016, its capacity will increase to roughly 20 million tonnes of cement per year. It is part of a vertically integrated production network with 1 aggregates plant, 10 storage sites, and 16 ready-mixed concrete plants, of which 3 are strategically located in the central business district.
