Around the world, over 1.5 billion rubber tires are produced on an annual basis. In the USA alone, 300 million tires are purchased each year. Now, at some stage, all of those tires require disposing of and global rubber waste is a major environmental issue. After all, did you know that a typical car tire will take over 80 years to decompose at a landfill site? Fortunately, tire waste is a great candidate for resource recovery via pyrolysis plant.
In years gone by, the economic viability of resource recovery from scrap tires did not make financial sense, so most tire waste was sent to landfills, incineration facilities, and seafills. Nowadays, however, pyrolysis plants make it economically viable to extract valuable resources from rubber waste. An average tire is comprised of 35-45% tire oil, 12% steel wire, 8% combustible gas and 35% carbon black. So, as you can see, there are lots of valuable materials in tire waste. With the right processing machinery, tire recycling plants can enjoy healthy annual profits.
The working principles of a tyre pyrolysis plant are relatively simple. To being with, tires are ground up into small pieces using automatic tire shredders. Next, the rubber waste is sent through a drying machine to reduce the moisture content as excess moisture can lead to inefficient pyrolysis since it causes stream production.
After the tire waste has been properly prepared it is transported into the main reactor via a conveyor belt system. The reactor is an oxygen-free environment and reaches temperatures higher than 400 degrees Celsius. The lack of oxygen is very important as its absence prevents combustion, which would result in heat and smoke production. Instead, the tire waste vaporizes into components of differing viscosities. The oil vapor is then channeled through a condensing system where it is converted into liquid fuel oil.
Many manufacturers that have rubber pyrolysis plants for sale also sell distillation machines. Such machines can be used for refining the fuel oil produced by pyrolysis. Of course, the oil doesn’t have to be refined, as in its raw state it can still be sold as a heavy fuel oil for various industries. Refining the pyrolysis oil into gasoline or diesel oil, however, can become a profitable option for many operations. For example, Beston Machinery will offer the related equipment for tyre recycling plant, such as shredder, dryer, pyrolysis machine, distillation machine, etc.
When comparing tire to oil plants for sale from different manufacturers, it’s important to take many variables into account. For instance, you need to look at a pyrolysis plant’s working method, reactor size, daily capacity, cooling method, operating pressure, lifespan, area requirements, price, etc. Some of the largest continuous pyrolysis plants have daily capacities of 24 tons. Meanwhile, smaller batch tire pyrolysis plants have daily capacities below 6 tons.
Tyre to oil plant cost varies widely based on the location of the supplier. In general, domestic manufacturers are unable to compete when it comes to Chinese tire pyrolysis plant prices. Therefore, it could be worth checking out some of the tire to oil machines for sale from manufacturers in China that export worldwide.
