This ‘Living’ Plastic Comes With a Built-in Kill Switch

A team of scientists in China recently demonstrated this somewhat comically idealistic solution, reporting their findings in a recent paper published in ACS Applied Polymer Materials. This new “living” plastic, as the team describes it, contains plastic-degrading microbes that activate and self-destruct on command. Although this isn’t the first time scientists have tested similar materials, the new experiment looks promising. A proof-of-concept test with a wearable plastic electrode confirmed that, as intended, the plastic degraded completely within two weeks.

Scientists had consistently explored whether some bacteria known to be capable of breaking down polymers could be engineered within plastic. In 2016, Japanese chemists planted a polymer-eating bacterium next to a plastic bottle to study how this could work. Other labs in the U.S. also developed biodegradable plastic prototypes built on similar premises.

The plastic is alive

The team behind the latest findings had investigated this possibility before. While the newest prototype builds on earlier attempts, it differs by using two enzymes instead of one, which had typically been the case so far. The goal was to engineer the bacterium Bacillus subtilis to produce two cooperative enzymes: one to snip the polymer chain and another to chew up these smaller bits into smaller molecules—essentially nothing.

I suspect I already have this issue with weed-wacker cord. If I don’t use it for a year or two, it seems to come apart faster. In the end this cord ends up in the environment, so its likely bio-degradable.

Sounds like a bio weapon. Can destroy anything made of plastic by infecting it with these microbes.

What could possibly go wrong?

I agree. A lot depends however, on the types of plastics that the bacteria can degrade. Consider the increasing use of polymers in the electrical components in data centers or in Automobiles. Imagine the fabric in your clothing starting to disintegrate!

Imagine walking through the supermarket aisle and turning on the plastic zapper!

Or watching cars dissolve into puddles right on the freeway.

Nah, I'd have it disintegrate the clothing of that hot blonde over there. It'd be better than X-Ray Specs!

Im picturing a far-side cartoon of women walking to car with plastic bags that disintegrate znd contents spill out and scientists with a remote control laughing behind a grocery store sign or some object
