SynPet - Model TCP -Thermal Conversion Process for Waste Recycling
SynPet has developed a groundbreaking technology known as the Thermal Conversion Process (TCP®), designed to transform a wide array of carbon-based waste materials into high-grade circular products for the petrochemical industry. Unlike traditional recycling processes such as pyrolysis or gasification which are limited to specific waste types and require extensive pre-treatment, TCP® employs water at elevated temperatures and pressures in a multi-stage thermal reaction. This method efficiently processes mixed and contaminated plastics without the need for sorting or heating. Spanning three critical stages - depolymerization, hydrolysis, and cracking - TCP® achieves the separation and conversion of complex waste streams into valuable feedstocks like circular naphtha substitutes and renewable resources. Demonstrated in Istanbul and now scaling industrially at Antwerp-Bruges, TCP® embodies a novel solution in advancing the circular economy by offering sustainable management of challenging waste forms like domestic, industrial, and hazardous waste.
Developed and validated over thirteen years of research, SynPet’s patented Thermal Conversion Process (TCP®) represents a breakthrough in chemical recycling. Unlike conventional recycling methods such as pyrolysis or gasification, TCP® uses water under elevated pressure and temperature in a multi-stage thermal reaction, enabling the conversion of mixed, contaminated, or non-recyclable plastic waste into valuable circular products — without sorting, drying, or combustion.
Initially developed and tested at SynPet’s demonstration plant in Istanbul, TCP® is now being scaled to industrial level through its first commercial facility in the Port of Antwerp-Bruges, Belgium.
The Miracle of Water
As a result of a decade long R&D studies, we have developed a technology that creates a circular economy by recycling wastes that cannot be recycled with current methods, such as pyrolysis or gasification.
Since this technology uses the most potent but harmless reagent, water, it does not require pretreatment for waste.
TCP is used in the production of miraculous products that are the core of our two waste management solutions.
Retriggering the Waste Lifecycle in 3 Steps
The Thermal Conversion Process consists of 3 stages where different waste treatment technologies serve a single purpose.
Depolymerization
Organic and inorganic substances that are treated with water under constant heat and pressure are separated by the depolymerization method. Organic-based materials are then transferred to the next step.
Hydrolysis
Carbon based molecules are broken apart using water gas shift reaction where hydrogen and hydroxide attach themselves to target carbons. This bond frees the carbon from all contaminants attached to it. Then, a secondary chemical reaction, decarboxylation, removes all oxygen from the hydrocarbon chains, producing pure long hydrocarbon chains.
Cracker
Thermal cracking is created by increasing the ambient temperature above 450 degrees. Thus, the chains of long-chain hydrocarbons are shortened. This results in high-quality products.
- Conventional technologies, such as pyrolysis or gasification, can only process certain types of plastic and household waste. This is where TCP differs from other methods.
- Its unique technology recycles all waste, including those that are routinely sent to landfills and incinerators, as their recycling is considered impossible with current methods.
- At the same time, current technologies require these wastes to be very clean, separated, or dried, which makes recycling costly and inefficient.
- Since TCP technology uses water, it does not require any pre-treatment for waste, and any waste can be added to the feedstock as unsorted and wet.
