Nearly everyone has seen large mountains of tires piled many hundreds of feet into the air, sometimes in rural settings and other times in the cities as well. It’s been estimated that in the US alone nearly 6 billion pounds of tires are produced each year and unfortunately, most of every tire goes to waste because only the outer edge ever touches the road. This is a huge environmental waste that turns into a real hazard if it catches fire and releases toxic fumes and dioxins. There is now a way to eliminate the entire problem using a process called pyrolysis to safely and cleanly recoup all of the original components involved. There are lots of tyre pyrolysis plants for sale that can safely recycle the problem tires.
Pyrolysis Is When The Tires Are Decomposed In The Absence Of Oxygen
When tires are burned they release toxic fumes that include dioxin, one of the strongest poisons known to man, plus large amounts of carbon dioxide as well. However, if they can be heated to a very high temperature without any oxygen present, then the dioxins are not created and the carbon dioxide stays chemically bound in the oil that the tires were made from
After the tires have completely decomposed into gases and a pile of black soot, the gases are run through a condenser that cools them down and most of them turn into oils. A good pyrolysis tire recycling system will separate the different oils by grade, light, medium, and heavy so they can each be sold to a different buyer.
Approximately 40% of the weight of each tire is made up of oil that is recoverable in the process, some of the pyrolysis plants then use that same oil to heat the reactors where the tires are melted down which can save considerably on the costs to run the plant.
The Black Soot Is Carbon Black
Carbon black has many uses in the automotive parts industry where it’s made into hoses, tires and other hard rubber parts. It’s also used in making the sheathing used on cables and wires, because it has excellent flexibility and resistance to electricity. Black plastic pipes, conveyor belts, fan belts, and doormats also get their strength and coloring from carbon black. It is usually made from oil, but the pyrolysis process can make it far cheaper and is very competitive in the open market.
The Gases That Are Made Are Very Compatible With Natural Gas
The typical gases that come from the process are of high grade and can be easily used in most natural gas applications or mixed with natural gas and sold to homes and businesses. It can also be used to generate electricity which is many times done right at the landfill and then sold straight into the grid.
