What is Tire-Derived Fuel?

Tire or rubber recycling can take on several forms. Tires can be reused in railway lines to reduce vibration. It can also be used as construction materials in playgrounds, running tracks, and other facilities.

One of the best ways to reuse scrap tires is to convert these to biofuel. Generally referred to as tire-derived fuel (TDF), it is a cleaner, more sustainable, and cheaper alternative to fuel. TDF provides an advanced and practical approach to tire recycling, and widely used in industrial facilities worldwide including pulp and paper kilns, cement kilns, and electric utilities.

As a supplemental fuel, it helps companies generate savings in energy costs while increasing boiler efficiency and lowering air emissions. It is estimated that more than half of the scrap tires generated yearly are used as TDF. This tire shredding system is in great condition and ready for your facility today.

With its high heat value, scrap tires are an excellent fuel source. Consider that the heating value of an average passenger tire can go up to 15,000 British thermal units (Btu) per pound, which is even better than the 12,000Btu per pound of coal.

On a grander scale, scrap tires represent a viable energy source. Based on the average discard rate of 300 million tires a year, it is estimated that old tires can produce energy equivalent to around 17 million barrels of oil. This is roughly less than 1% of the energy needs in the United States.

Application of Tire-Derived Fuel
As mentioned earlier, biofuel from scrap tires is useful in various industries such as cement manufacturing. TDF is used by cement makers to augment their fuel for firing cement kilns. The use of tires as fuel has also been proven to help in reducing the emission of harmful chemicals into the air.

TDF is also tapped by pulp and paper companies to supplement wood waste, the main fuel used in powering pump mill boilers. TDF has a higher heat value than wood waste while helping overcome operating problems such as low heat content and high moisture content. The use of TDF likewise helps pulp and paper mills lower their fuel costs and improve their combustion efficiency. It can also help improve the public image of paper mill boilers.

To conclude, converting scrap tires into biofuels present a practical energy source for many industries around the world. Thermal conversion of tires into an alternative and clean fuel is considered an environment-friendly and practical approach to disposing of a difficult solid waste. More at Harvest Machinery
