    If the fuels used for firing the kiln are the highest variable cost then reducing those costs must be the first priority of cost minimisation. If the traditional fossil fuel used for firing the kiln can be partially replaced by a lowercost alternative then the profit margin from the production of clinker and cement must increase.

    Tyre chips or Tyre Derived Fuel TDF was first used in cement kilns, in Germany, in the 1970s. Few years later, kilns in the USA began using TDF, which proved quite a popular step. At present, USA produces over 300 million used tyres annually, out of which around 150 million are converted into TDF, their cement industry using approximately 60 million tyres worth in its kilns.

    In a typical cement kiln some 200 tonnes per hour of sintering material passes the burners. The ashes of the fuel used to heat the kiln drops into the glowing material and reacts with the hot minerals to become an integral part of the endproduct clinker. This clinker is then ground into cement.
