Today's KNOWLEDGE Share : Highlights marine biodegradability of Eastman Aventa™ compostable materials

Today's KNOWLEDGE Share

New research highlights marine biodegradability of Eastman Aventa™ compostable materials

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 70% of their mass after 36 weeks of incubation in seawater. In contrast, polystyrene foams a material commonly used for food packaging showed no signs of degradation. The study found that CDA foams degrade faster than any material evaluated under environmentally relevant marine conditions more than quadruple that of paper and up to 1,000 times greater than solid polypropylene, polystyrene and polylactic acid (PLA).  


“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 $1 billion by reducing costs associated with plastic pollution. The study highlights the need for holistic assessments of environmental impact to avoid swapping one issue for another.  


“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.”

Today's KNOWLEDGE Share : Differential Shrinkage Driven Warpage Problem

Today's KNOWLEDGE Share

How to experimentally spot a differential shrinkage driven warpage problem ?

If you are molding a relatively uniform thickness part and suffer from warpage, there is a nice trick to experimentally separate the contribution of differential shrinkage from other sources of problems (differential cooling, anisotropy).


Just make parts that are roughly full (say, 99% full), with zero packing (no pressure, no time). By not packing, you avoid packing one area better than another (for instance overpacking the gate area vs. distant areas). As a result you have a lighter part, with sink marks all over and voids, but with essentially NO DIFFERENTIAL SHRINKAGE. If this "short shot" is flatter than your packed part, you have experimentally demonstrated a strong contribution from "uneven packing", i.e. differential shrinkage.
Learn about all this in detail in my online course on the packing phase.

Today's KNOWLEDGE Share : Researchers Develop New Way to Create Stronger Adhesives with Salt

Today's KNOWLEDGE Share

FAMU-FSU researchers pioneer new adhesive polymer technology using a secret ingredient found on your kitchen table.

Adhesives are everywhere, from the tape used in households to the bonding materials in vehicles and electronics. The search for stronger, more adaptable adhesives is ongoing and may come down to adding a dash of salt to two special polymer ingredients known as polyzwitterions, or PZIs.

New research from a FAMU-FSU College of Engineering team led by Hoyong Chung, an associate professor in the Department of Chemical and Biomedical Engineering, shows a new way to create adhesives by using the natural attraction between positively and negatively charged materials. The work was recently published in Journal of the American Chemical Society.

“We want to create stronger and more versatile adhesives using a strategy involving electrostatic interactions,” Chung said. “Our research centers around two special polymers, known as PZIs, with the goal of getting them to bond more effectively.”

The research team was interested in how the shape of the polymer affects its stickiness, comparing bottlebrush polymers (which have branches coming off the main chain) to straight-chain (linear) polymers. These two differently shaped polymers can be engineered to improve their adherence properties.


One of the study’s key findings is that by simply adding sodium chloride — table salt — the strong but brittle polymers are transformed to be strong and flexible. Most adhesives are either strong or can stretch a lot, but it’s difficult to find adhesives that do both. The amount of salt is key to making the adhesive strong but stretchy.

“The initial key to our discovery lies in the sophisticated and precise design and synthesis of multifunctional polymers,” Chung said. “This new polymer could have wide-reaching impacts across several industries, offering a way to tailor the toughness and flexibility of adhesives with precision. The finding challenges previously held beliefs about adhesion and salt.”

Chung and his team’s discovery lays the groundwork for creating better industrial adhesives and highlights the importance of electrostatic interactions in developing new materials. The findings provide a promising step in their goal of crafting ideal adhesives for a myriad of uses. The study will continue, focusing on developing biomedical tissue adhesives with drug delivery, imaging and disease diagnosis functions.

Chung collaborated on this study with Biswajit Saha, a postdoctoral researcher at the FAMU-FSU College of Engineering and Jacob Boykin, a graduate student. Saha is the first author on the publication.

“Our discovery shows that adding salt could be a key to making an adhesive that is both strong and flexible,” Saha said. “We believe that the study provides a steppingstone toward the long-term goal of developing ideal adhesives.”

The research was funded through Florida A&M University by a $763,457 four-year grant from the National Science Foundation.

Today's KNOWLEDGE Share : Ethylene Production Based On Steam Cracking:

Today's KNOWLEDGE Share

Knowledge of Petrochemical units:

Ethylene Production Based On Steam Cracking:


Ethylene production is primarily achieved through steam cracking, where hydrocarbons like ethane, propane, or naphtha are heated to high temperatures (around 800-900°C) in the presence of steam. This process breaks down large hydrocarbon molecules into smaller ones, with ethylene being a major product. The cracked gases are then rapidly cooled to stop the reactions, and the mixture is sent through a series of separation and purification steps to isolate ethylene. Ethylene is a key building block in the petrochemical industry, used to produce various plastics, chemicals, and synthetic materials.

-------------------------------------------




Process Flow Diagram Overview:

Using the basic flow sheet in the appendix:


Feed Furnace: The hydrocarbon feedstock (e.g., ethane or naphtha) is preheated in the feed furnace to around 400°C.


Cracking Furnace: The preheated feed is further heated to about 800°C in the cracking furnace, where thermal cracking occurs. This high temperature breaks down the hydrocarbons into smaller molecules like ethylene, propylene, and other by-products.


Quenching: The cracked gas is rapidly cooled in a quenching system to stop further reactions. This is typically done using water or oil quenching.


Caustic Wash: The cooled gas undergoes a caustic wash to remove acidic impurities like hydrogen sulfide and carbon dioxide.


Drier: The gas is then dried to remove any remaining moisture.


Cold Box: The dried gas is cooled further in a cold box to condense and separate the lighter hydrocarbons.


Demethaniser: The gas enters the demethaniser, where methane is separated from the mixture.


De-ethaniser: The remaining gas is sent to the de-ethaniser, where ethylene and ethane are separated from heavier hydrocarbons.


Ethane Product Compressor: Ethane is compressed and recycled back to the cracking furnace.


Secondary Demethaniser: Further separation of methane from the gas mixture.


Ethane Depropaniser: Separation of propane from the ethane-ethylene mixture.


C2 to C4 Splitter: Separation of ethylene (C2) from other hydrocarbons like butanes (C4).


MAPD Converter: Conversion of methyl acetylene and propadiene (MAPD) impurities to ethylene and propylene.


Final Purification: The purified ethylene is then compressed and stored or sent for further processing.
