Plastic-Eating Microbes to the Rescue!

Not all heroes wear capes... nor are they all "larger than life." 

They may in fact be microscopic... and they maybe bit-sized bacteria. Bioengineered to eat their way through problems, these mini-sized superheroes are environmental problem solvers.... designed to digest plastic waste!

In an innovative twist, there is a growing field of science dedicated to the microscopic solution to a major problem: plastic pollution. Scientists are working to "genetically train" minuscule bacteria (called microbes) to break down PET plastic, which is the plastic used in soda bottles, clam-shell style plastic food containers, and synthetic fibered fabrics. 

Yes, it sounds more like science-fiction than science. 

But it is not new, and dates back to over two decades:

• In 2001, Japanese scientists led by Kohei Oda discovered a collection of bacteria at a garbage area that were degrading plastic. "Eating" it, if you will. As they consumed this plastic trash, it led to the bacteria to grow and multiply. 
• Scientific research over time led to the 2016 discovery by Kohei Oda and Kazumi Hiraga that the microbe Ideonella sakaiensis' enzymes could break down PET plastic. This in turn served as energy for the microbes.

Working in labs through research like this, scientists have discovered that they could help fast-track this process through genetic engineering. This "superpower" of science, combined with technology, helps speed up the process, helping to power through the plastic pollution problem. Of course, "speeding up" is all relative as it is currently still a rather slow process.

There's a name for this: biorecycling. It also could potentially help turn the plastic waste into new products, which ultimately saves resources down the line. Biorecycling is an emerging and growing field, so it not an overnight solution, Yet, it does open up possibilities of cleaning up oil spills, eliminating microplastics from water sources, and helping tackle hard-to-recycle materials. Additionally, with it being a new-technology, there are a lot of unknowns. Last thing anyone wants is for a solution to create new problems. Especially environmentally. (We've all seen the damage invasive species can do. Take Kudzu, Spotted Lanternflies, and Asian Carp for example.)

But it's hopeful to see a shift in the idea of "waste" as an end product. Rather than a dead end, it shifts to a "circular economy" model, transforming an item into something new rather than ending it in waste and pollution. Kind of nice to have a clean up crew of nature's tiny microbes!
