Recycled PET often exhibits yellowing or color variations due to degradation during the recycling process. These additives are developed to withstand multiple recycling loops, helping the recycled material remain visually appealing even after several uses. These additives should not negatively impact the recyclability of PET and should help maintain the integrity of the recycled material.

Our technologies help to reduce material usage, improve container recyclability, and improve physical performance and reuse potential of recycled materials. Ultimate is recognized by the Association of Plastic Recyclers and the European PET Bottle Platform for having no negative impact on the recycling stream. Cesa™ NOX A4R Additive for Enhanced Recycling stabilizes recycled polyolefins during processing, enabling a higher quality level of recyclate and better end-use products.

reSound™ REC Recycled Content TPEs: The new AF 7210 series of reSound REC TPEs contain 51 – 59% recycled content, including a minimum of 37% from post-consumer recycled (PCR) sources, including closed-loop feedstock from within the automotive industry. Gravi-Tech™ REC Recycled Formulations: These density-modified engineered polymer materials include up to 98% recycled content, offering a more sustainable alternative than density-modified grades based on prime or virgin polymers. Unique technologies that improve the recyclability of products and enable recycled content to be incorporated, thus advancing a more circular economy

Recycle Solutions Additionally, new minimum recycled content thresholds will mean that from 2025 there will be a sales ban on PET bottles containing less than 25% recycled plastics, increasing to 30% in 2030. The plastic packaging recycling target in Germany will rise to 63% from 2022 and the new law also introduces incentives for packaging producers to incorporate recyclability considerations into their packaging design, and to use recycled or renewable materials.
