CORVALLIS, Ore. – Let’s talk plastic and chemicals folks. To start, researchers,
including an Oregon State University College of Engineering faculty member, have
taken a key step. Especially toward greatly expanding the range of plastics and 
their [chemicals](https://greenlivingguy.com/2020/06/plastic-a-toxic-love-story-susan-freinkel/)
that can be recycled.

The findings, published today in Science, are important. That’s because [plastic](https://greenlivingguy.com/2025/09/pfas-chemical-waste-a-growing-environmental-concern/)
and chemical waste is a massive problem. For that’s both globally and in the United
States. Especially where only about 5% of used [plastic is recycled](https://greenlivingguy.com/2014/04/going-green-includes-polystyrene-foam-recycling/).
That’s according to the U.S. Department of [Energy’s National Renewable](https://greenlivingguy.com/2025/10/fossil-fuels-cost-reasons-for-their-decline-explained/)
Energy Laboratory, which led the study.

Packaging materials, containers, and other items are filling up landfills. These
plastics have chemicals inside them. For they are littering the environment at a
pace. So rapidly that scientists estimate by 2050, the ocean will have more plastic
and chemicals by weight than fish. All most interestingly according to NREL.

## The Research and Technology

A collaboration led by NREL’s Gregg Beckham and including Lucas Ellis, an OSU researcher
who was an NREL postdoctoral fellow during the project, combined chemical and biological
processes in a proof of concept to “valorize” mixed plastic waste. Valorize means
to enhance the value of something.

The research builds on the use of chemical oxidation to break down a variety of 
plastic waste types. It’s a method from a decade ago by chemical industry giant 
DuPont.

“We developed a technology that used oxygen and catalysts to break down plastics
into smaller, biologically friendly chemical building blocks,” said Ellis, an assistant
professor of chemical engineering. “From there we used a biologically engineered
soil microbe capable of [consuming and ‘funneling’ those building](https://greenlivingguy.com/2015/04/gold-transparency-building-consumer-trust/)
blocks into either a biopolymer or a component for advanced nylon production.”

Beckham, a senior research fellow at NREL and the head of the Bio-Optimized Technologies
to keep Thermoplastics out of Landfills and the Environment Consortium – known as
BOTTLE – said the work provides a “potential entry point into processing plastics
that cannot be recycled at all today.”

Current recycling technologies can only operate effectively if the [plastic](https://greenlivingguy.com/2008/03/green-transportation-start-up-wins-competition/)
inputs are clean and separated by type, Beckham explains.

Plastics can be made from different polymers, each with its own unique chemical 
building blocks. When polymer chemistries are mixed in a collection bin, or formulated
together in certain products like multilayer packaging, recycling becomes expensive
and nearly impossible. That’s because the polymers often have to be separated before
they can be recycled.

## Simplifying Plastic Recycling

“Our work has resulted in a process that can convert mixed plastics to a single 
chemical product,” Ellis said. “In other words, it is a technology that recyclers
could use without the task of sorting [plastics](https://greenlivingguy.com/2024/05/plastic-bottle-recycling-life-cycle-educating-kids-on-plastic-waste/)
by type.”

Researchers applied the process to a mix of three common plastics: polystyrene, 
used in disposable coffee cups; polyethylene terephthalate, the basis for carpets,
polyester clothing, and single-use beverage bottles. Also, high-density polyethylene
used in milk jugs and many other consumer plastics.

The oxidation process broke down the plastics into a mixture of compounds. It includes
benzoic acid, terephthalic acid and dicarboxylic acids. Such acids in the absence
of the engineered soil microbe would require advanced and costly separations to 
yield pure products.

The researchers engineered the microbe, Pseudomonas putida. That’s to funnel the
mixture into one of two products biologically. For instance, polyhydroxyalkanoates
which is an emerging form of biodegradable bioplastics. Also, beta-ketoadipate, 
which professionals can use in the manufacture of performance-advantaged nylon.

According to the researchers, trying the process with other types of plastics is
the focus of upcoming work. That’s plastic, such as polypropylene and polyvinyl 
chloride.

“The chemical catalysis process we have used is just a way of accelerating a process
that occurs naturally. So instead of degrading over several hundred years, you can
break down these plastics in hours or minutes,” said co-author Kevin Sullivan, a
postdoctoral researcher at NREL.

So instead of just having [recycling bins for schools](https://easirecycling.com.au/education-waste-management/),
these guys are learning how to break down plastics. All for a safer environment,

Funding was provided by the U.S. Department of [Energy’s Advanced Manufacturing Office and Bioenergy Technologies](https://greenlivingguy.com/2014/07/micro-chp-energy-technology-for-sustainable-homes/)
Office. Moreover, the work is part of the BOTTLE Consortium.

In addition, scientists from the Massachusetts Institute of Technology, the University
of Wisconsin-Madison and Oak Ridge National Laboratory also took part in the study.

In conclusion, NREL is the U.S. Department of [Energy’s primary national](https://greenlivingguy.com/2011/12/national-geographic-energy-quiz/)
laboratory for renewable energy and energy efficiency research and development. 
Finally, operation is for the department by the Alliance for Sustainable Energy,
LLC.
