End Of Life Tire Recycling – New Approach

Scrap Tires - Solid Waste Managment

The ultimate model which addresses all possible aspects of environmental sustainability in rubber recycling is still Devulcanization but should start right from the collection of tires. This means the starting point should be at the tire collection centers or in the US possibly at the landfills. Here we are not talking about solid waste management anymore but effectively managing a vital raw material in process.

Addressed properly the tires would not be dumped in the open but would be separated out between passenger car and commercial vehicle (truck) tires, making it possible to split up the feedstock into types ie. Mostly Natural Rubber (80/20) from Commercial vehicle tires and Mostly Synthetic (60/40) for passenger car tires. This important step also makes it possible to shoe horn in a step which could see the eventual removal of the Butyl inner liners by grinding or peeling off. The resultant by-products would be butyl scrap feedstock and butyl free scrap tire feedstock, an interesting and very significant change to the current situation.

Scrap Passenger Car Tires & Tire Derived Fuel

Incineration as Tire Derived Fuel

The misconception that End of Life passenger car tires have no real value needs to be challenged and corrected. Today there are a few plants scattered around the world that crumb the material but it looks like the vast majority are incinerated as tire derived fuel (TDF). The approach to tire recycling thus far has been following the paths of least resistance with few technological strides of consequence. The primary problem in passenger car tires is the lower rubber recovery with a high fibre content,
