  • Can scrap tyres be used as alternative fuels?
  • The use of alternative fuels and raw material is common practice in the European cement industry. Dirk Lechtenberg gives an overview of scrap tyres as an alternative fuel in this excerpt from MVW Lechtenberg & Partner's Alternative Fuels & Raw Materials Handbook.
  • Why do tyre burning kilns reduce alumina modulus?
  • Iron - Normally the retention time for complete tyre burning in the kiln is long enough to convert the steel carcass into iron components that are incorporated into the clinker minerals. Therefore the alumina modulus decreases. This benefits the substitution of any corrective material, for example natural iron ore.
  • What is the calorific value of scrap tyres?
  • Calorific value - The calorific content value of tyres is between some 6450kCal/kg and 8000kCal/kg (S. Sprung). To substitute 1t of coal (some 6100kCal/kg) around 0.76 - 0.95t of scrap tyres is needed. Compared to pet coke (some 8200kCal/kg) the substitution factor is slightly more.
  • What is a scrap tyre?
  • Scrap tyres are tyres that are no longer suitable or legal for their intended use due to damage, brittleness or low tread depth. By the time it is scrapped, a tyre generally loses around 20% of its weight. Tyres comprise natural rubber, synthetic rubber, carbon black, oil and various reinforcers. Quantity and availability
