They remain as a gas which can be burned as fuel. f> The minerals that were part of the tire, about 40 to 45 % by weight, are removed as a solid. g> When performed well a tire pyrolysis process is a very clean operation and has nearly no emissions or waste. h> The properties of the gas, liquid and solid output are determined by the type of feed stock used and the process conditions. i> For instance whole tyres contain fibers and steel. Shredded tyres have most of the steel and sometimes most of the fiber removed. j> Batch wise Process is done by tyre pyrolysis. k> The steel can be removed from the solid stream with magnets for recycling. The remaining solid material, often referred to as "charcoal".
