Leading Manufacturer, Supplier & Retailer of Indonesian Steam Coal and Wood Charcoal.
Steam coal from Indonesia has a very low content of ash and sulfur. The sulfur content is clearly below 1%. The largest share of the mined coal is of low calorific range with a calorific value between 5, 500 and 6, 000 kcal/kg. In the high calorific range coal between 6, 100 and 6, 700 kcal/kg is mined. Indonesia produces primarily steam coal. Due to scarce resources, Coking coal for coke production is of minor importance.
Indonesian steam coal exports are primarily directed towards the Pacific market; only a low amount of tonnages is exported to Europe and America. In those countries Indonesia is used as "Swing-Supplier", i.e. coal supplies depend on attractive price and market situations. The most important buyer of Indonesian steam coal in the Pacific area is Japan with approximately 35 million tons. Other buyers are in particular Taiwan, South Korea and India. China with approximately 20 million tons per year is also an important buyer. Another future increase of the supplies is expected for the People's Republic of China.
Charcoal is a light, black residue, consisting of carbon and any remaining ash, obtained by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by slow pyrolysis, the heating of wood or other substances in the absence of oxygen (see char and biochar). It is usually an impure form of carbon as it contains ash; however, sugar charcoal is among the purest forms of carbon readily available, particularly if it is not made by heating but by a dehydration reaction with sulfuric acid to minimise the introduction of new impurities, as impurities can be removed from the sugar in advance. The resulting soft, brittle, lightweight, black, porous material resembles coal.[disputed discuss]
