Recent Advances in Sustainable Materials: Eastman's Copolyester Resins

Eastman, a global leader in specialty materials, has recently achieved significant recognition for its commitment to sustainability. Eight of its copolyester resins have received RecyClass recyclability approvals, emphasizing the company's efforts to integrate recycled content into their products. This accolade is particularly important in an era where environmental responsibility is becoming increasingly paramount.

What Are Copolyesters?

Copolyesters, particularly those recognized by Eastman, are variants of polyethyleneterephthalate (PET) specially designed for enhanced performance in various applications. Known for their clarity, durability, and resistance to heat, these materials are commonly utilized in packaging solutions across several industries, including cosmetics and personal care products.

Details on the Approved Resins

Out of the eight copolyester resins, six have been identified as fully compatible with state-of-the-art PET recycling processes in Europe. The standout resins include:

• - Cristal™ EN076
• - Cristal™ One
• - Cristal™ One Pro
• - Cristal™ One IM812
• - Cristal™ One E
• - Cristal™ One E Lux

Two additional grades, known as Cristal™ EN067 and Cristal™ EN059, have been recognized for their limited compatibility. This distinction reflects their performance in conjunction with existing recycling systems.

Independent Testing and Validation

The approvals follow a series of independent tests conducted by PTI-Europe and Plastics Forming Enterprises. These evaluations utilized a modified protocol to assess the recyclability of PET bottles. Importantly, these modified copolyesters do not interfere with established recycling processes, making them a valuable solution for packaging applications unrelated to beverages, such as skincare and cosmetic items.

The Importance of Recyclability

The significance of these approvals extends beyond mere recognition. As industries strive to reduce their environmental footprint, recyclable materials serve as a crucial component in achieving sustainability goals. By ensuring that their packaging solutions are compatible with existing recycling frameworks, Eastman is paving the way for a more circular economy.
