On 24 October, we received an inquiry from a German client about waste tyre pyrolysis plant in Germany. The client wants to know more about SUNRISE waste tyre pyrolysis machines. Because Germany offers financial subsidies and incentives for recycling, and Germany produces millions of tyres a year, so they have a big waste tire management problem. Pyrolysis, a form of WtE, could be the answer. The client wants to know if pyrolysis technology can be used for tire recovery and how. The following is what we talked about with the German client.
How to build a tire pyrolysis facility in Germany?
The German tire market is huge and is expected to grow at a CAGR of 3.80% during 2024-2032. With sufficient supply of scrap tires as raw materials, our German customers are interested in setting up a tire pyrolysis plant. They asked about the details of setting up a plant to start the business as they are considering using it for scrap tire management and recycling projects. To answer their questions about scrap tire pyrolysis, let’s start with the basics.
Supply Chain Management
The first and foremost step in setting up a tyre pyrolysis plant is to ensure a steady supply of used tyres. You can establish connections with Germany tyre dealerships, automotive repair shops, and waste management facilities to procure waste tyres at a reasonable cost. In any case, as long as you can ensure that you have a sufficient source of scrap tires.
Pre-Processing of Tyres
To enhance the efficiency of the pyrolysis process, it is advisable to pre-process the tyres. Shredding the tyres into smaller, more uniform pieces allows for more even heat distribution during pyrolysis. A double-shaft shredder is an excellent choice for this task. It can handle large volumes of tyres and produce uniformly sized pieces, which not only improves the pyrolysis process but also facilitates the handling and transportation of the tyre pieces within the plant. Please kindly note that if your raw material is already shredded tires, then this step can be skipped.
Tyre Pyrolysis Process You Must Know
Waste tires are fed into the pyrolysis furnace. As the tires are heated in the pyrolysis reactor, which is typically heated to a temperature range of around 400 to 600 degrees Celsius, the complex polymers in the tires start to break down. During this thermal decomposition, various products are formed.

How to Choose Pyrolysis Furnaces for Tire Pyrolysis Plant?
Then we keep discussing with the German client. The client wants to set up a pyrolysis plant to recycle tyres and other rubber waste. They inquire which pyrolysis furnaces are best for their recycling plant.
Actually when choosing a tire pyrolysis furnace, it’s essential to consider different operating modes such as Batch, Semi – continuous, and Fully continuous.

How much profit can you make from tire pyrolysis recycling?
The client wants to invest in a tyre-recycling plant now. Therefore, they asked about the profit from tyre pyrolysis recycling. “We wanted to know how much money this recycling production line could make.” This is also a question that most customers are very concerned about. Actually this depends on many things.
Scale of Your Pyrolysis Plant
Pyrolysis Product Prices and Market Demand
Is there any customized scrap tire pyrolysis solution reference?
oLet’s differentiate based on processing capacity. The following we’ll provide you with German waste tire pyrolysis recycling production line of different scales for reference. Customers can make adjustments as needed:
Small tire pyrolysis recycling production line proposal (suitable for start-ups or experimental production)
The daily processing volume of waste tires is about 1-2 tons, mainly producing rubber particles, some steel wires, and pyrolysis oil.
Before pyrolysis
Tire shredder
Use a powerful rotating knife roller to crush tire blocks into 1-3 cm pieces, with a power of 15-20 kilowatts and a processing efficiency of 0.8-1.2 tons per hour. There is a simple screening net inside to initially separate large-sized impurities.
Magnetic separator
Placed on the crushed material conveyor belt, it recovers steel wire through strong magnetic adsorption, with a separation efficiency of more than 90%, and the purity of the recovered steel wire can exceed 85%.
Tire crusher
further crushes the primary crushed materials into 0.5-1 mm rubber fine powder, with its own air cooling system to prevent overheating and bonding, and an hourly output of 0.5-0.8 tons.
Pyrolysis machine(optional)
