Scientists discover bacteria that eat plastic Scientists have developed self-destructive plastic . Scientists say that this will help reduce pollution. Polyurethane , i.e. plastic, is used everywhere. Since it is difficult to recycle, it is disposed of in landfills. However, scientists have found a scientific solution to this. Scientists have developed a plastic that self-destructs by incorporating particles of plastic-eating bacteria . Those bacterial particles remain inactive as long as the plastic is being used. However, when the plastic is disposed of after use, they revive and start eating the plastic. University of California researcher Han Sol Kim says that this gives us hope that we can reduce plastic pollution in nature. In addition, it has another advantage that the bacterial particles of plastic-eating bacteria increase the hardness of the plastic. Another researcher, John Pokorsky, says, “Our process makes the material stronger, which increases its useful life. And, wh...
