Ces immenses terre-pleins sont constitu\u00e9s de cendres volantes r\u00e9sultant des op\u00e9rations de liqu\u00e9faction du charbon, r\u00e9alis\u00e9es par les installations industrielles de la compagnie p\u00e9troli\u00e8re sud-africaine Sasol toutes proches. Il s\u2019agit de la plus importante \u2013et sans doute de la seule\u2013 usine de carburant de synth\u00e8se du monde. Elle utilise le proc\u00e9d\u00e9 Fischer-Tropsch pour convertir des charbons de mauvaise qualit\u00e9 mais aussi du gaz naturel en hydrocarbures liquides. L\u2019usine \u00e0 elle seule occupe une superficie de 13 km2 et sa cr\u00e9ation doit beaucoup \u00e0 l\u2019embargo international auquel l\u2019Afrique du Sud \u00e9tait soumise lorsque ce pays pratiquait une politique rigoureuse de s\u00e9gr\u00e9gation et de discrimination raciales au profit de la minorit\u00e9 blanche, plus connue sous le nom d\u2019Apartheid. Si la production de carburant synth\u00e9tique est rest\u00e9e marginale, la technologie conna\u00eet un regain d\u2019int\u00e9r\u00eat avec l\u2019augmentation des prix du p\u00e9trole. D\u2019un point de vue environnemental, la production d\u2019un litre de carburant synth\u00e9tique issu du charbon engendre deux fois plus de gaz \u00e0 effet de serre qu\u2019un carburant \u00e9quivalent issu du raffinage du p\u00e9trole.<\/p>\n","protected":false},"excerpt":{"rendered":"
