How Trinseo Manufactures Bio-Attributed Materials Based on Mass Balance

Trinseo offers its flagship STYRON™ Polystyrene, MAGNUM™ ABS, and TYRIL™ SAN with renewable content, part of our portfolio of sustainably advantaged products as BIO products. Here's how we create our materials with renewable content based on Mass Balance.


First, renewable raw materials are purified and processed in a refinery producing Bio Feedstock.

Feedstock Cracking

We use a bio-waste conversion process called feedstock cracking to separate biomass into its monomer building blocks. Only chemicals needed in production of the end material are filtered off for utilization during production.


We then manufacture a combination of bio-content and fossil-based material. The result is a risk-free, drop-in solution.


The material is sent to the customer for a variety of end markets.

Mass Balance

Throughout the process, we use the Mass Balance approach and certifications to track inputs and outputs when mixing sustainable and non-sustainable materials in a production process.

Mass Balance: Refining, Feedstock Cracking, Manufacturing, Customer


Our finished product results in a superior material, while helping our company and customers:

  • Support a circular economy
  • Save fossil resources
  • Reduce carbon footprint
  • Provide transparency, traceability, and quantifiable data to support corporate goals
