Waste tyre pyrolysis process:The pyrolysis method for recycling used tyres is a technique which heats whole or shredded tyres in a reactor vessel containing an oxygen free atmosphere and a heat source.

• In the reactor the rubber is softened after which the rubber polymers continuously breakdown into smaller molecules.

• These smaller molecules eventually vaporize and exit from the reactor.

• These vapors can be burned directly to produce power or condensed into an oily type liquid, generally used as a fuel.

• Some molecules are too small to condense. They remain as a gas which can be burned as fuel.

• The minerals that were part of the tyre, about 40 to 45 % by weight, are removed as a solid.

• When performed well a tyre pyrolysis process is a very clean operation and has nearly no emissions or waste.

• The properties of the gas, liquid and solid output are determined by the type of feed stock used and the process conditions.

• For instance whole tyres contain fibers and steel. Shredded tyres have most of the steel and sometimes most of the fiber removed.

• Batch wise Process is done by tyre pyrolysis.

• The steel can be removed from the solid stream with magnets for recycling. The remaining solid material, often referred to as "charcoal".
