Molten Technology

Innovative leap in tire recycling

ABOUT THE PROJECT

The Molten® technology used by Contec S.A. is an advanced chemical recycling process for tires by pyrolysis, based on molten salts. The result is: recovered carbon black (ConBlack®), recovered oil (ConPyro®) and steel (ConWire®). All of these products can be reused in industry. In turn, the pyrolytic gas produced during the process is used as a source of energy (high self-sufficiency).

WHAT NEEDS DOES THE INNOVATION ADDRESS?

Molten technology addresses the key challenges of waste management and sustainability. Millions of tons of waste tires are generated worldwide each year, with landfilling and incineration posing environmental risks. Traditional disposal methods generate large amounts of CO₂ and toxic substances. Contec S.A.’s solution allows efficient processing of rubber waste and recovery of valuable raw materials such as ash oil, carbon black (rCB) and synthesis gas. The innovation supports a closed-loop economy, reduces greenhouse gas emissions and reduces dependence on fossil fuels in industries.

COMPETITIVE ADVANTAGES

We are the first pyrolysis plant in the world to use liquid salt as a heat transfer medium. This solution allows us to keep the process running under optimal conditions, making it safer, more efficient and more economical. The molten salt in the tank is injected into a closed circuit, where it distributes the heat around the reactor and then returns to the tank through a specially designed heater. The liquid salt has very good heat transfer characteristics, allowing greater control over the entire process and ensuring reproducible product quality. By using molten salt, the temperature in each part of the reactor is practically the same, thus avoiding thermal stresses which translates into excellent safety parameters.
