Frequently Asked Questions
What capacity of plants do you offer?
We offer plants with standard size 30 000 tonnes of tyres per year (tpa). The plant has a modular design with 6000 tpa for each module.
A 18 000 tpa plant has 3 modules
A 30 000 tpa plant has 5 modules
and so on.
Is 10 000 ton capacity available?
Depending on market conditions it might be achievable but we normally do not recommend a capacity below 18 000 ton per year.
What types of tyres can be processed in the plant?
Our technology can handle any type of tyres, from passenger car to OTR. The limitation is the size of the shredded tyre parts.
Our process works best with tyre chips with a size of 20-150 mm
What are the requirements of the shredded tyres into the process?
The size of the material can be between 20mm to 150mm and needs to be washed from most dirt and gravels. The steel wire should not be removed since it has a function during the pyrolysis
Is it possible to use complete tyres?
No, the process requires a material format as described above. This is important for the possibility to obtain high quality material output.
Do you use rubber granulates?
No, granulates are not optimal in the CFC process. Granulation is a quite expensive preprocessing step compared to shredding.
Is it expensive to reduce the size of the tyres into shreds?
Depending on market the cost for shredding is about 10-30 €/ton.
What kind of equipment is required for shredding?
There are many options on the market to reduce the size of tyres. We are happy to recommend a suitable solution for your needs if needed.
Is the process running continuously?
The CFC system is a semi-batch technology where the reactors operate independent of each other, but preferably in a sequence.
What are the valuable materials recovered by the process?
The CFC-technology is recovering about 30% Carbon black, 45% oil, 15% steel and the rest is gas. The gas is used to run the process efficiently and is more or less self-sufficient in the main process.
There are a few solutions offered from China, why is your process more competitive?
The Chinese systems are normally based on continuous systems with rotating drums that are relying on rubber granulates. The granulates are expensive to produce and the technology of external heating is normally not able to produce a quality carbon black that can be used by the rubber industry.
This kind of traditional pyrolysis comes with various problems such as
- too low temperature
- too high temperature
- explosive atmosphere
- dust in the oil
- high maintenance
- low lifetime
- oil residue left in the carbon black
- smelly carbon black
The CFC process from Scandinavian Enviro Systems does not have these problems
What is the CAPEX of a CFC-plant?
The investment is depending on several parameters related to the market conditions and the project scope. Is there already available resources such land, buildings or equipment? In some cases parts of the equipment can be sourced locally based on our specifications.
What is the project time from start to commissioning?
Depending on how well prepared the customer is and what the market conditions require in the terms of feasibility study. The time from order to handing over is estimated to 20-24 months.
