A novel plastic that decomposes after useproduced by University of Tokyo researchers is loaded with enzymes that cause it to degrade in water spontaneously.
Plastic contamination in the water has now become a global environmental problem.
This study will aid in the reduction of plastic pollution in the ocean.
Similarly, researchers at Huazhong University of Scienceand Technology, China, produced a plastic polymer that dissolves after only a week of contact with sunshine and air.
The scientists worked on a polymer sheet that changes color based on pH levels and an improved chemical sensor.
Because of the material's peculiar molecular structure and the whining chains of monomers, it provided the film with a deep red color and vanished as soon as the bonds broke.

Why We Need Decomposable Plastic?

Since the 1950s, humans have discarded 6.3 billion metric tons of plastic, with just 600 million metric tons recycled, leaving 4.9 billion metric tons in landfills or otherwise contaminating the environment.
Plastic trash is a concern because it does not decompose and instead breaks down into smaller particles known as microplastics, which have invaded practically every area of the world and human bodies.
Biodegradable polymers were meant to remedy this issue, but they have three major drawbacks.
  • They become mixed up and pollute recyclable plastics.
  • They end up in landfills, where the conditions are not favorable for plastic breakdown, and thus last as long as everlasting polymers.
  • When composted, they do not entirely decompose and leave microplastics in the soil.

Decomposable Plastic Is The Solution

Nature uses enzymes to break things down in the wild, and even after we die, enzymes cause our corpses to disintegrate naturally.
The new method includes integrating polyester-eating enzymes into the plastic while it is being manufactured.
These enzymes are shielded by a simple polymer wrapper that keeps the enzyme from unraveling and becoming ineffective.
When exposed to heat and water, the enzyme sheds its polymer cloak. It begins chewing the plastic polymer into its building pieces, in the case of polylactic acid, converting it to lactic acid, which may be fed to composting soil bacteria.
The polymer covering dissolves as well.
According to the researchers, up to 98 percent of their modified polymers transformed into tiny molecules, leaving no microplastics.
After roughly a week at room temperature, the polymers had disintegrated by 80%.
Plastics deteriorated significantly quicker under the intense heat of industrial composting settings.
They vanished after a few days in warm tap water.

Conclusion

Various researchers are striving to develop ways to make highly decomposable plastic, as well as other types of degradable polymers, viable.
Still, they anticipate that commercialization is many years away.

He regularly writes science articles and blogs for science news website immersse.com and open access publishers OA Publishing London and Scientific Times. He loves to keep himself updated on scientific developments and convert these developments into everyday language to update the readers about the developments in the scientific era. His primary research focus is Plant sciences, and he contributed to this field by publishing his research in scientific journals and presenting his work at many Conferences. Shah graduated from the University of Agriculture Faisalabad (Pakistan) and started his professional carrier with Jaffer Agro Services and later with the Agriculture Department of the Government of Pakistan. His research interest compelled and attracted him to proceed with his carrier in Plant sciences research. So, he started his Ph.D. in Soil Science at MNS University of Agriculture Multan (Pakistan). Later, he started working as a visiting scholar with Texas A&M University (USA). Shah’s experience with big Open Excess publishers like Springers, Frontiers, MDPI, etc., testified to his belief in Open Access as a barrier-removing mechanism between researchers and the readers of their research. Shah believes that Open Access is revolutionizing the publication process and benefitting research in all fields.
