Disposal of scrap tyres is a major environmental problem. The most promising solution of this complex issue is tyre derived fuel. Pyrolysis process is used to do the same. In this presentation pyrolysis process is explained. When pyrolysis on scrap tyres is done then three products are obtained: oil, pyro gas, and char. A pyro gas used as energy source for pyrolysis reactor and char used to provide strength for structural applications, and oil is used as fuel, this indicates the proper utilization of scrap tyre. Properties of TPO was compared to standard fuel and found similarities. And noticed blending of TPO with Jatropha methyl ester makes it an alternate for fuel.

3. Scrap Tyres
Disposal of waste tyres becoming complex.
In the world, India is the third largest producer, fourth
largest consumer of natural rubber and fifth largest
consumer of synthetic rubber.
Disposal of waste tyre has become a major
environmental problem.

12. TPO is a Hydrocarbon liquid generated
by de-polymerisation of waste tyres.
Applications: In electric generators,
boilers, diesel pumps, furnaces, hot
water generators, hot air generators,
thermic fluid heater etc.

Tyre pyrolysis oil
15. Jatropha methyl ester (JME), whose cetane number (50 – 58.4)
has marginally higher than diesel was blended at different
proportions with TPO.
So, that the TPO can be used as an alternative fuel. JMETPO20
gives the optimum result.
Proposed Solutions
16. It is concluded proper utilisation of tyre is possible.
Pyrolysis is one of the simplest methods to recycle the
waste automobile tyres in to useful energy.
TPO can be considered as an alternative fuel.
