PS-17 · Pyrolysis oil
Pyrolysis oil
Industrial fuel or refinery feedstock, depending on specification.
PYR · Technologies
From end-of-life tires to products with a market.
Plants for the thermochemical processing of end-of-life tires, selected plastic streams and other compatible feedstocks. They recover liquid, gaseous and solid fractions according to material composition and process design.
PS-08 · Pyrolysis
Operating principle
Pyrolysis
Pyrolysis thermally decomposes organic matter in the absence of oxygen. Without combustion, polymer chains break into vapors that condense as oil, a non-condensable gas reused as process fuel, and a carbon-rich solid residue. With tires, the reinforcing steel is recovered clean.
| Atmosphere | Oxygen-free, sealed reactor |
|---|---|
| Heating | Indirect, with process gas as main fuel |
| Operation | Continuous or batch, depending on capacity |
| Products | Oil, gas, recovered carbon and steel |
How it works
The process, stage by stage
Every plant is designed around these stages. The final configuration depends on the analysis of your feedstock and the products you want to obtain.
Stage 01 / 06
Receiving and preparation
Weighing, batch registration, shredding and, if required, prior steel separation.
Stage 02 / 06
Sealed feeding
Continuous reactor feeding without air ingress, using lock and screw systems.
Stage 03 / 06
Reactor
Thermal decomposition with controlled temperature and residence time to steer the yield of each fraction.
Stage 04 / 06
Condensation
Staged vapor cooling, fraction separation and oil storage.
Stage 05 / 06
Gas and emissions
Scrubbing of non-condensable gas, return to the reactor burner and flue gas treatment.
Stage 06 / 06
Solids
Closed-loop discharge and cooling, magnetic steel separation and carbon conditioning.
Feedstocks
- Whole or shredded end-of-life tires
- Polyolefins (PE, PP) and technically suitable blends
- Industrial rubber and rubber scrap
- Other streams, subject to laboratory characterization
Products
PS-18 · Recovered carbon black
Recovered carbon black
Filler for rubber, plastics, pigments or solid fuel, depending on grade.
PS-19 · Steel
Steel
High-quality scrap for steelmaking.
PS-21 · Process gas
Process gas
Thermal self-supply for the reactor; surplus can generate power.
Typical mass balance
Reference yields in tire rubber pyrolysis
Laboratory tests between 450 and 600 °C on steel-free rubber. At industrial scale yields depend on the tire and the process: a mining-tire facility in Chile reports 40% carbon black and 20% steel. Your balance is defined by characterizing your feedstock.

Why this technology
01
EPR compliance
A documented recovery route for the tire management schemes required by extended producer responsibility laws.
02
Saleable products
Each fraction has a market: revenue depends on product quality and consistency, not just volume.
03
Energy self-sufficiency
Process gas covers most of the reactor heat once at steady state.
PyroTrack
Every batch, recorded in PyroTrack
Inputs, process conditions and products are traced for operations, regulatory reporting and certification.
FAQ
Frequently asked questions
What capacity can a plant have?
It is sized to the available feedstock volume and business model. We work from modules for a single generator or manager to continuous lines for regional management schemes.
Can any plastic be processed?
No. Polyolefins are the most suitable. PVC and PET require specific evaluation because they affect oil quality and equipment corrosion.
How are emissions controlled?
The process is closed: non-condensable gas is scrubbed and burned as fuel, and flue gases are treated before the stack. Design follows the emissions standard of the project country.
