The push towards a circular economy is one of the most significant industrial shifts of our generation. We are moving away from the linear “take, make, use, dispose” model and embracing a system where resources are reused, recycled and repurposed.

Navigating the Complexity of Recycled Materials

For the plastics, rubbers and composites industries, this transition presents both immense opportunities and formidable technical hurdles. The primary challenge? The inherent variability of recycled feedstock.

Unlike virgin materials, which conform to precise, consistent specifications, postconsumer and postindustrial recycled materials are a mixed bag. They vary in composition, suffer from degradation after multiple processing cycles and contain impurities. These inconsistencies can lead to unpredictable processing behavior and final products with compromised performance.

How Additives Can Help

Advanced additives offer effective solutions to these challenges. By acting as compatibilizers, melt flow and viscosity modifiers, lubricants, coupling agents and odor neutralizers, advanced additives can transform imperfect feedstocks into viable materials. This not only improves processing efficiency but also enhances the quality of the final products.

Despite their significant benefits, advanced additives aren’t a one-size-fits-all solution. They often require careful customization to address the unique challenges of each application. Variations in recycled feedstock compositions, differences in processing techniques and diverse end-product requirements necessitate the use of tailored formulations or combinations of additives.

Struktol has been producing specialty additives for rubbers, plastics, and composites for decades, and we have witnessed a dramatic growth in the need for solutions to challenges with recycled feedstock.

By fine-tuning additive solutions to meet these specific needs,…
