High purity styrene
Produces styrene that reaches ASTM grade styrene monomer
Handles contaminated feedstocks
Processes even feedstocks contaminated with flame retardants to food grade materials
Attractive business cases
Process capable to be cost efficiently delivered at scale
EcoStyrene™ polystyrene recycling
Despite producing millions of tons yearly, polystyrene recycling remains low just 16% in China, 7% in Europe, and under 1% in the US.
Contamination and logistics keep most polystyrene out of the recycling stream. EcoStyrene changes the story. This innovative technology transforms even heavily contaminated polystyrene into ultra-high purity styrene turning waste into valuable new material.
Main benefits
Minimizing feedstock costs: Process allows broader feedstock specification, including construction waste contaminated with flame retardants
Maximizing styrene revenues: Process capable in providing high yields at attractive capital intensity
Guaranteed performance: Individual unit operations proven in commercial scale
Key characteristics
High purity styrene: process capable in delivering styrene monomer even for food applications
Reliability: process fully tested from lab to pilot scale
High yield: reactor technology providing high yields at scale, thus resulting in attractive business economics

EcoStyrene is an advanced chemical recycling process that transforms contaminated polystyrene waste into high purity styrene monomer, suitable for food-grade plastics and other demanding applications.
Traditional recycling struggles with contaminated polystyrene. EcoStyrene overcomes this by processing even heavily contaminated feedstocks, significantly increasing recycling rates and supporting a circular economy.

Mechanical recycling relies on physical sorting and melting but cannot handle contaminated or complex waste streams. EcoStyrene uses advanced chemical processes to break down polystyrene into its original monomer, enabling the production of new, high-quality plastics.
EcoStyrene can process a wide range of polystyrene waste, including materials contaminated with flame retardants (like PolyFR and HBCD) and food residues feedstocks that are typically rejected by other recycling methods.
By converting waste polystyrene back into valuable styrene monomer, EcoStyrene reduces landfill and incineration, lowers the carbon footprint, and supports the transition to a circular economy for plastics.
