Positive work is being done globally to cope up with the growing volume of used tyres. Most of waste tires end up in landfills instead of being fed into rubber granulators for particle size reduction to be used for applications like sports and playground surfaces or blended with asphalt for road making. Meanwhile, there is the green steel making technology that will provide real economic and environmental benefits to communities.
Green steel making technology has been integrated into commercial steel production in Australia, Thailand, South Korea, Norway and the United Kingdom. Green steel technology provides multiple benefits because it reduces the volume of used tyres in landfills and reduces the cost of EAF steelmaking. The environmental footprints of the steel industry are also significantly minimized.
In India, used tyres are incorporated into conventional EAF steelmaking without the need for modern and expensive industrial infrastructures or large scale equipment. End-of-life tyres and post-consumer plastics are used as the alternative carbon unit in green steelmaking to avoid the unnecessary extraction of coal.
A blend of coke and rubber is injected as an option to pure coke to improve slag formation and furnace efficiency. The process can consume about 2.4 million recycled tyres. It is important to revolutionize the recycling process because waste tyres are a potential source of valuable hydrocarbons.
The Polymer Injection Technology (PIT) or green steel is a simple modification of the conventional steel manufacturing process. The technology precisely controls the injection of waste tyres that have been granulated into the conventional Electric Arc Furnace used for steel making. Granulated tyres will partially replace non-renewable coke.
As long as the process of injection in the furnace is precisely calibrated, granulated tyres can be the source of hydrocarbons. Years have been spent in experimenting high temperature reactions when tyre granules partially take the place of coke.
Recycling plants require rubber granulators to achieve extremely clean rubber from the waste tyres that are processed. The high performance machine is also the solution when size reduction is required from materials to generate the proper size required for production processes. With different rotor designs, the machine can be efficiently used for various applications.
