Borealis is investing more than € 100 million to expand and upgrade its polypropylene (PP) compounding facilities in Schwechat, Austria.  The new production line is scheduled to begin operations in the second half of 2026. 

The expansion will increase the supply of advanced PP compounds mainly used in consumer products, mobility, and infrastructure applications.  

Polymer compounding is the process of blending plastic resins, such as polypropylene, with additives, fiberglass, and recycled materials to create specialty compounds with tailored properties. These materials are designed for applications that require durability, heat resistance, or lightweight performance.   

“This is our third significant investment this year, following the expansion our energy business and the increase in capacity for our recyclable, lightweight polymer foam solutions. Over the past decade, Borealis has built strong expertise in circular solutions that meet our customers’ expectations for quality. With more capacity, we can deliver more of the materials they need, helping them hit performance targets and move closer to their sustainability goals.  This project transforms innovation into tangible solutions – bringing our We4Customers strategy to life,” says Stefan Doboczky, Borealis CEO.
