We treat our phones as necessary extensions of ourselves, and it is now hard to imagine life without what has become like an additional limb. Similarly, we have grown so used to computers, cars, and items requiring batteries that many of us would...

CEP: Catalyzing Commercialization - A Biodegradable Plastic Made from Waste Methane

February

Catalyzing Commercialization
What if we could make the Great Pacific Garbage Patch just disappear? What if plastics didn’t accumulate in our landfills? What if we could reduce greenhouse gas emissions while replacing up to 30% of the world’s plastics with a biodegradable substitute? Researchers have tried for decades to achieve these goals. One approach being taken is the development of an efficient production process for poly-hydroxyalkanoate (PHA) — a biodegradable polymer similar to the polypropylene used to make yogurt containers.

Chem Economics
T. Kevin Swift
Not all polymers are useful and/or processable in their natural form. Thus, functional chemicals are added to polymer resins to facilitate processing and to enhance, extend, or otherwise modify the properties of the plastic products manufactured from polymer resins. Such plastic additives represent a $4.6-billion business in the U.S.

Kirk Richardson
Replacing materials and equipment as they corrode or reach the end of their service life is one of the challenges of managing an aging plant. When a material or part is no longer available because the supplier discontinued the product line, was acquired by another company, or went out of business, it can be difficult to find another source or suitable replacement.
