What is TDF TYRE derived fuel? How is TDF made?

TDF (Tyre Derived Fuel) is a coal or wood alternative fuel produced from waste tyres. With the increasing awareness of resource recycling, waste treatment and oil price inflation, TDF has gained significant attention in recent years. Here we will explore the two primary types of TDF production and their making process.

TDF tyre derived fuel making processes

This type of tyre derived fuel making process involves mechanically shredding waste tires into smaller pieces through steel wire drawing machine, waste tyre shredding and crushing machine, typically 1 to 4 inches in size. These shredded tires can be used directly as fuel in various industrial applications such as cement kilns, paper mills, and power plants. The shredded tires are often mixed with other fuels like coal, wood, or chemical waste to enhance combustion efficiency and reduce costs.

This kind of TDF tyre derived fuel production process has the following features:

1. Simple Process: The TDF production process is relatively straight-forward, requiring only basic waste tyre shredding equipment.

2. Cost-Effective: It offers a low-cost solution for waste tyres disposal while providing an alternative fuel source.

3. High Energy Content: Tyres have a higher energy content compared to traditional fuels, making them efficient for energy generation.

4. Disadvantages---Environmental Concerns: Burning shredded tyres directly can release harmful emissions if not properly controlled. The use of shredded tyres as fuel is mainly restricted to specific industrial settings with appropriate emission control systems.

Pyrolysis technology is a thermal decomposition process carried out in the absence of oxygen, which breaks down waste tires into valuable products. And the overall output of the TDF making process is 40% (pyrolysis) TDF tyre derived fuel, 30% carbon black, 15% steel and 10-15% gas.

The tyre derived fuel pyrolysis making process mainly includes the following steps as showed in the working video of waste tyre pyrolysis machine: feeding, heating, pyrolysis, cooling, gas purification.

This kind of TDF making way stands out by the following features:

1. Environmental Benefits: Pyrolysis technology reduces waste tire disposal issues and minimizes environmental pollution.

2. High-Quality Products & Wide Applications: The pyrolysis process yields high-quality products that can be utilized in multiple applications. The tire pyrolysis oil (TDF/TPO) has a high calorific value, making it an efficient energy source for industrial and boilers heating, such as steel/cement/glass/china making factories and heavy oil power plants. The tire pyrolysis oil can be further refined into non-standard diesel used in ships, tractors, diesel generators, etc.

But the pyrolysis process has limits, which requires specialized TDF pyrolysis production machine and technical expertise. And setting up a tire pyrolysis plant involves relatively big capital expenditure.

While both processes of TDF making have their merits, pyrolysis technology stands out as a more sustainable and environmentally friendly approach. As environmental regulations become stricter and the demand for renewable energy sources grows, pyrolysis-derived TDF is poised to play a crucial role in the future of waste tire recycling and energy production.
