New Research Highlights Marine Biodegradability of Eastman Aventa(TM) Compostable Materials
A new study published in ACS Sustainable Chemistry & Engineering reveals that cellulose diacetate (CDA)-based foams made with Eastman Aventa materials show rapid marine biodegradability. The research, led by Woods Hole Oceanographic Institution, demonstrates that these foams lost up to 70% of their mass after 36 weeks in seawater, while polystyrene showed no degradation.
The CDA foams degrade more than four times faster than paper and up to 1,000 times faster than conventional plastics. The study suggests that switching from polystyrene to CDA-based foams for food trays could save society over $1 billion in pollution-related costs. Aventa, derived from sustainable wood pulp, is also being used for compostable straws and cutlery.
Un nuovo studio pubblicato su ACS Sustainable Chemistry & Engineering rivela che le schiume a base di diacetato di cellulosa (CDA) realizzate con materiali Eastman Aventa mostrano una rapida biodegradabilità marina. La ricerca, condotta dal Woods Hole Oceanographic Institution, dimostra che queste schiume hanno perso fino al 70% della loro massa dopo 36 settimane in acqua di mare, mentre il polistirene non ha mostrato alcuna degradazione.
Le schiume CDA si degradano più di quattro volte più velocemente della carta e fino a 1.000 volte più velocemente delle plastiche convenzionali. Lo studio suggerisce che passare dal polistirene alle schiume a base di CDA per le vassoi alimentari potrebbe far risparmiare alla società oltre 1 miliardo di dollari in costi legati all’inquinamento. Aventa, derivata dalla polpa di legno sostenibile, è anche utilizzata per cannucce e posate compostabili.
Un nuevo estudio publicado en ACS Sustainable Chemistry & Engineering revela que las espumas de diacetato de celulosa (CDA) elaboradas con materiales Eastman Aventa muestran una rápida biodegradabilidad marina. La investigación, liderada por el Woods Hole Oceanographic Institution, demuestra que estas espumas perdieron hasta el 70% de su masa después de 36 semanas en agua de mar, mientras que el poliestireno no mostró degradación.
Las espumas de CDA se degradan más de cuatro veces más rápido que el papel y hasta 1,000 veces más rápido que los plásticos convencionales. El estudio sugiere que cambiar del poliestireno a espumas a base de CDA para bandejas de alimentos podría ahorrar a la sociedad más de 1 mil millones de dólares en costos relacionados con la contaminación. Aventa, derivada de pulpa de madera sostenible, también se utiliza para pajillas y cubiertos compostables.
ACS Sustainable Chemistry & Engineering에 발표된 새로운 연구는 Eastman Aventa 소재로 제작된 셀룰로오스 디아세테이트(CDA) 기반의 폼이 해양 생분해성이 빠르다는 것을 밝혔습니다. Woods Hole 해양학 연구소가 주도한 연구에 따르면, 이러한 폼은 바닷물에서 36주 후 70%까지의 질량을 잃은 반면, 폴리스티렌은 어떤 분해도 나타내지 않았습니다.
CDA 폼은 종이보다 네 배 이상 빠르게 분해되며, 기존 플라스틱보다 최대 1,000배 더 빠르게 분해됩니다. 연구는 식품용 트레이에 폴리스티렌 대신 CDA 기반 폼을 사용하는 것이 사회에 10억 달러 이상의 오염 관련 비용을 절감할 수 있다고 제안합니다. 지속 가능한 나무 펄프에서 유래한 Aventa는 또한 퇴비화 가능한 빨대와 식기류에도 사용됩니다.
Une nouvelle étude publiée dans ACS Sustainable Chemistry & Engineering révèle que les mousses à base de diacétate de cellulose (CDA) fabriquées avec des matériaux Eastman Aventa montrent une biodégradabilité marine rapide. La recherche, dirigée par le Woods Hole Oceanographic Institution, démontre que ces mousses ont perdu jusqu'à 70 % de leur masse après 36 semaines dans l'eau de mer, tandis que le polystyrène n'a montré aucune dégradation.
Les mousses de CDA se dégradent plus de quatre fois plus vite que le papier et jusqu'à 1 000 fois plus vite que les plastiques conventionnels. L'étude suggère que passer du polystyrène aux mousses à base de CDA pour les plateaux alimentaires pourrait permettre à la société d'économiser plus de 1 milliard de dollars en coûts liés à la pollution. Aventa, dérivée de pâte de bois durable, est également utilisée pour des pailles compostables et des couverts.
Eine neue Studie, die in ACS Sustainable Chemistry & Engineering veröffentlicht wurde, zeigt, dass aus diacetatierter Cellulose (CDA) hergestellte Schäume aus Eastman Aventa-Materialien eine schnelle marine Biodegradierbarkeit aufweisen. Die Forschung, die vom Woods Hole Oceanographic Institution geleitet wurde, zeigt, dass diese Schäume nach 36 Wochen in Meerwasser bis zu 70% ihrer Masse verloren haben, während Polystyrol keine Zerfall zeigte.
Die CDA-Schäume zersetzen sich mehr als viermal schneller als Papier und bis zu 1.000-mal schneller als herkömmliche Kunststoffe. Die Studie legt nahe, dass ein Wechsel von Polystyrol zu CDA-basierten Schäumen für Lebensmittelbehälter der Gesellschaft über 1 Milliarde Dollar an kosten im Zusammenhang mit Verschmutzung sparen könnte. Aventa, das aus nachhaltigem Holzschliff stammt, wird auch für kompostierbare Strohhalme und Besteck verwendet.

Insights
KINGSPORT, TN / ACCESSWIRE / December 5, 2024 / A groundbreaking new study published in ACS Sustainable Chemistry & Engineering reveals that cellulose diacetate (CDA)-based foams made with Eastman Aventa™ compostable materials rapidly biodegrade in the marine environment. The article concludes that biodegradable, CDA-based foams are commercially useful and will not persist in our oceans as plastic pollution.
Scientists from Woods Hole Oceanographic Institution (WHOI), the world's leading independent, nonprofit organization dedicated to ocean research, exploration and education, led the study. WHOI's research and journal article focuses on CDA-based foams made with Aventa, which lost up to
"Foaming biodegradable bioplastics like Aventa offer a promising strategy to reduce the environmental impact of frequently mismanaged consumer plastics, particularly in food packaging applications," said Collin Ward, associate scientist at WHOI and lead researcher for the study. "These materials not only degrade rapidly in the ocean but also support circularity and material efficiency."
The study dives deeper into a systems-level assessment for redesigning plastic articles for food packaging applications, considering material performance, economics, sustainability and circularity. Aventa is a cellulosic material derived from sustainable wood pulp, ensuring a renewable and sustainable beginning of life, and its compostability translates into a sustainable end of life.
Polystyrene is commonly used in food packaging, but it is not biodegradable and is difficult to recycle. The study concludes, through calculations that include annual consumption rates and the social costs of pollution, that switching from polystyrene to CDA-based foams for food trays could potentially save society more than
"Traditional plastic foams face challenges in end-of-life management, often unintentionally ending up as plastic pollution in the environment," said Jeff Carbeck, vice president of Eastman corporate innovation and care solutions technology. "Eastman Aventa materials offer a sustainable alternative, and this research shows that CDA-based foams will not contribute to persistent marine plastic pollution."
Aventa is also being used as a compostable solution for other single-use applications such as disposable straws and cutlery.
