What is Next Nature?

With our attempts to cultivate nature, humankind causes the rising of a next nature, which is wild and unpredictable as ever. Wild systems, genetic surprises, autonomous machinery and splendidly beautiful black flowers. Nature changes along with us.

Designing Bugs That Eat Plastic

Designing Bugs That Eat Plastic

It is a well known secret that plastic hardly breaks down and almost all of the plastic ever made still floats around somewhere. With the great pacific garbage patch now twice the size of Texas and over 500 billion plastic bags produced a year – which take about a 1000 years to decompose – plastic is well on its way of becoming a basic material in the Earth’s ecosystem.

Earlier, we’ve discussed some of the dramatic effects of this material and suggested how a future microbe able to digest plastic could thrive on the vast amount of plastic ‘food’ available in the biosphere. It might take a million years, however, for a plastic-eating microbe to evolve.

WHY WAIT FOR EVOLUTION?

But why wait for evolution? 16-year old high school student prodigy Daniel Burd already developed a microorganism that can rapidly biodegrade plastic. Daniel realized something that even the most esteemed PhD’s had not considered: Although plastic is one of the most indestructible of manufactured materials, it does eventually decompose. This means there must be microorganisms out there to do the decomposing.

Daniel wondered whether those microbes could be bred to do the job faster and tested this by a simple yet clever process of immersing ground plastic in a yeast solution that encourages microbial growth. After which he only had to isolate the most productive organisms – a sort of speedup of evolution. His first results were encouraging, so he went on, selecting out the most effective strains and interbreeding them. After some weeks of tweaking and optimizing temperatures he achieved a 43% degradation of plastic in six weeks.

Daniel presented a his results at the Canadian Science Fair in Waterloo, Ontario where he won the first price for his study. Meanwhile another 16-year old girl from Taiwan already discovered a microbe able to break down Styrofoam.

THE ATTACK OF THE PLASTIC EATING MICROBES

Of course it is exciting to have such young geniuses creating plastic eating microbes, however, we should keep in mind that we are ‘playing with fire’ and be concise on the applications. One of the main advantages of plastic – and why we use it everywhere – is that it is not biodegradable. Plastic is used in hospitals, vehicles, homes, industrial settings, etc.

Although it sounds like a great idea to have a colony of plastic-eating microbes clean up the oceans, one can also easily imagine the potential drawbacks of having a plastic-eating bug out in the wild. Perhaps the risk of microorganisms eating up your garden furniture is still acceptable, yet having them enter a hospital setting will be more problematic.

Hence, we should be careful on letting these bugs out in the open and keep in mind that, with every attempt to control nature, we may cause the rising of a next nature which is wild and unpredictable as ever.

  1. I don’t think we have to fear the attack of the plastic eating microbes. Microbes already exist that consume plastic. The problem is that plastic and plastic bottles in particular, are made so durable that microbes have a hard time identifying it as a food source. They eventual y will (biodegrade)but estimates are that it will take some plastic anywhere from 500-10000 years to biodegrade….and that’s way too long for humans. We are an environmental company that wanted to do something about the growing problem of plastic bottles. As you know, less than 30 percent are recycled and while recycling is a good thing, it is failing miserably at solving the plastic pollution problem. Our bottle the Enso Biodegradable plastic bottle is standard PET plastic with an additive that attracts microbes…those microbes already exist and the attractant lets them know that the plastic is a food source.
    When microbes consume plastic in the anaerobic environment of a landfill they produce methane. At first glance one might think that methane, a green house gas is making matters worse. Well, it turns out that methane from garbage is known as landfill gases (LFG’s). The federal government in the U.S. has mandated that all landfill operators capture LFG’s and now many are selling the gas to be used to produce energy. We promote the development of a new landfill design known as Bioreactor landfills. Bioreactor landfills are more efficient at biodegrading waste and producing/capturing LFG’s. What better use of our trash than to turn it into clean energy.

    I was wanting to know what kind of insect eats plastic. We have them….they ate through the bottom of a rubbermaid plastic canister.
