Avient Corporation announced an expansion to its portfolio of Maxxam BIO bio-based polyolefins, strengthening its commitment to provide more sustainable solutions. The new grades utilize natural fillers such as cellulose fiber or recycled coffee grounds, which would otherwise go to waste, providing an alternative to conventionally filled polyolefins.

“We are constantly innovating to bring our customers new solutions that can help them reach their sustainability goals,” remarked Matt Mitchell, director of global marketing, Specialty Engineered Materials at Avient. “In this case, our material science expertise has enabled us to utilize, and give value to, a material that would otherwise go to waste, contributing to a more circular economy.”  

Initially launched at K 2022, Maxxam BIO bio-based polyolefins are formulated with both bio-based resin and/or filler from natural sources such as olive seed powder.

Avient extends bio-based polyolefin range, utilizing cellulose fiber and recycled coffee grounds.

The portfolio now includes newly added grades with up to 40% filler from cellulose fiber or powder made from recycled coffee grounds. They can be based on either prime or bio-based resin. Incorporating a bio-based resin with a natural filler further enhances sustainability and reduces product carbon footprint compared to fossil feedstock alternatives.

Aside from sustainability benefits, utilizing bio-based fillers improves lightweighting compared to polymers traditionally filled with talcum, calcium carbonate, or glass fiber. Both cellulose and coffee-filled grades have good gloss and surface finish.

Coffee-filled grades offer unique differentiation through visual appearance, and cellulose-filled grades are easy to color and show improved mechanical properties compared to mineral-filled alternatives. Depending on customer requirements, these formulations can be customized to provide additional performance characteristics such as scratch, UV, and mold/fungi/bacteria resistance.

Maxxam BIO bio-based polyolefins with cellulose fiber or coffee powder can be useful for applications such as automotive interiors (decorative parts, trunk side liners, pillars, T-cup holders), consumer products (table and kitchenware, household goods), and packaging caps and closures.
