Degradation of PET Plastic with engineered environmental bacteria

Introduction:- PET Plastic is one of the most commonly used plastics in our daily life. It is used
in bottles, food containers , and clothes. However, this plastic does not break down easily and
causes serious environmental pollution.

Problem:- PET waste collects in the environment and turns into microplastics. These tiny
particles can harm animals, water, and even human health. It is difficult and recycle all PET
waste.

Solution:- Scientists have found a new method to solve this problem. They used bacteria and
enzymes to break down PET plastic. These microorganisms can convert plastic into smaller and
useful substances . This process is more eco-friendly than chemical recycling.

Impact in India:- In India, plastic pollution is a big problem.This method can help reduce plastic
waste in cities and rivers. It can also improve recycling systems. However, this technology may
be costly and not easily available everywhere.

Environmental Effects:- This method can reduce pollution in soil and water. It can also protect
animals and marine life . Less plastic means a cleaner and healthier environment.

Conclusion:- To make this method common, more research and government support are
needed. People should and also be aware of plastic waste.
