Discovering the Breakthrough in Marine Biodegradability

Revolutionary Study on Eastman Aventa™ Compostable Materials

Recent research has unveiled compelling evidence regarding the marine biodegradability of cellulose diacetate (CDA)-based foams made from Eastman Aventa™ compostable materials. The study presents a significant advance in our understanding of how these materials decompose in ocean environments, bringing hope for resolving plastic pollution issues.

Key Findings of the Research

Conducted by scientists at the Woods Hole Oceanographic Institution (WHOI), this study highlights that CDA-based foams crafted from Aventa materials exhibit a remarkable capacity for biodegradation. After being exposed to seawater for 36 weeks, these foams showed a mass loss of up to 70%, in stark contrast to conventional polystyrene foams, which displayed no signs of degradation whatsoever.

Comparative Analysis of Decomposition

The findings further reveal that CDA foams decompose faster than any other material assessed under similar marine conditions. Their biodegradation rate surpasses that of paper by four times and is up to 1,000 times quicker than materials like solid polypropylene and polylactic acid (PLA).

Why Eastman Aventa™ Matters

Collin Ward, an associate scientist at WHOI and the study's lead researcher, emphasized the importance of using biodegradable bioplastics such as Eastman Aventa™. He stated, "These materials not only decompose rapidly in ocean environments but also promote sustainability and efficient material use."

A Vision for Sustainable Packaging

The study advocates for a holistic approach to redesigning packaging materials, focusing on performance, economic factors, and sustainability. Aventa's composition, made from renewable wood pulp, establishes a strong foundation for both its lifecycle and end-of-life applications.

Financial Implications for Society

Switching from polystyrene to CDA-based foams in food packaging could potentially save society over $1 billion annually. This is achieved by reducing the financial burdens associated with plastic pollution, demonstrating the economic viability of sustainable materials.

The Limitations of Traditional Plastics

Eastman Aventa™ presents a welcomed alternative to traditional plastic foams that often contribute to environmental damage. Jeff Carbeck, the vice president of Eastman corporate innovation and care solutions technology, pointed out the challenges that traditional plastics face concerning end-of-life management. "CDA-based foams do not contribute to persistent marine plastic pollution, making them a valuable ecological solution," he remarked.

Diverse Applications of Aventa

Beyond the immediate benefits regarding marine biodegradability, Aventa is being embraced for various single-use applications, including disposable cutlery and straws. This versatility positions Eastman Aventa™ as a crucial player in the shift towards sustainable product offerings.
