Utilization of coal and waste for ecological fuel production

When processing brown coal mined in the North Bohemian Basin, dusty types of low heating coal containing lots of ash are produced. This coal is difficult to sell. On the other hand when bituminous coal is produced, the waste is very fine, with a high calorific value, which is impossible to sell. World wide continuously increasing amounts of waste and their further processing is a big problem. For processing waste combined with coal the most suitable types of waste are those individual types of coal which use favourable qualities of reprocessed high-energy waste.
