Zeopore and BioBTX increase the yield of circular aromatics from waste plastics thanks to a breakthrough in catalyst and process synergy

A Breakthrough in Chemical Recycling

Zeopore and BioBTX have successfully demonstrated a vital synergy between advanced catalyst engineering and innovative thermochemical processing, significantly enhancing the production of circular aromatics from waste plastics. This joint development represents a major technological leap forward in the chemical recycling industry, addressing the persistent challenge of converting low-value, mixed plastic waste into high-value chemical building blocks.

Maximizing BTX Yields Through Process Synergy

Aromatics—specifically benzene, toluene, and xylene (BTX)—are essential foundational chemicals for producing high-performance plastics such as PET, polycarbonates, and polyurethanes. Traditionally derived entirely from fossil fuels, these chemicals can now be generated from waste feedstocks using BioBTX’s Integrated Cascading Catalytic Pyrolysis (ICCP) technology.

By integrating Zeopore’s highly accessible, mesoporized zeolite catalysts into this system, the partnership has unlocked new efficiency levels. Zeopore’s specialized tuning of zeolite catalysts optimizes their internal pore structures, allowing larger, complex plastic polymer molecules to be cracked and converted more effectively. When paired with BioBTX’s two-step ICCP process—which isolates the initial thermal cracking from the subsequent catalytic conversion step—the optimized catalyst severely reduces unwanted byproducts like coke formation. The result is a substantial increase in the yield and selectivity of valuable circular aromatics, alongside an extended operational lifespan for the catalysts themselves.

Advancing the Circular Economy for Plastics

This breakthrough directly tackles critical bottlenecks in the plastics manufacturing industry: reducing reliance on virgin petrochemicals and establishing viable end-of-life pathways for complex, hard-to-recycle plastic waste streams. Because the resulting circular BTX molecules are chemically identical to their fossil-based counterparts, they serve as exact drop-in replacements for existing supply chains.

Manufacturers can seamlessly integrate these sustainable aromatics into the production of robust bioplastics and fully circular polymers without altering existing infrastructure. By lowering operational costs and increasing product yields, the Zeopore and BioBTX collaboration makes the large-scale commercialization of circular aromatics highly economically competitive.
