Eating plastic enzymes will turn waste into treasure

August 03, 2023

Plastics can be recycled to a certain extent. However, compared to other materials, this is a more difficult process and an expensive process, but it seems that scientists may have come up with a way to solve our plastic problem. This is in the form of "mutant" enzymes that can eat plastic bottles.

Researchers were initially inspired by a bacterium found in Japan in 2016 that naturally evolved to eat the plastic found in garbage dumps. The team's plan was to adjust the enzymes to see how it evolved, but it seems that their efforts to better understand the enzyme inadvertently resulted in more efficient enzymes.
It is said that this enzyme is very effective. It takes only a few days to start decomposing plastics. It is much faster than natural processes and may take centuries. Researchers are optimistic that this can be further accelerated and eventually become a viable large-scale process.
According to John McGeehan, a professor at the University of Portsmouth in the United Kingdom, “What we want to do is use this enzyme to change this plastic back to its original composition so we can recycle it into plastic. This means we don’t need Excavating more oil, fundamentally, it should reduce the amount of plastic in the environment. "
