Plastics have formed an indispensable component of virtually every consumer good. However, they also contributed substantially to contamination the marine environment. The world lacks a well-meaning effort curtail plastic waste. pollution crisis arising from inappropriate disposal or mismanaged wastes has driven strategies repurpose, reuse, and recycle products. Extensive research is continuing aiming produce new generation plastics that are collectively referred as bioplastics. Ideally, bioplastics degraded utilized by surrounding microorganisms, eliminating them our biodegradable still only small percentage global market, many not biodegradable. While good for environment, their position singular credible solution waste debated. In addition, there misunderstandings misconceptions about use, leading lack awareness acceptance.

Plastic pollution has become a major global concern, posing numerous challenges for the environment and wildlife. Most conventional ways of plastics degradation are inefficient cause great damage to ecosystems. The development biodegradable offers promising solution waste management. These designed break down under various conditions, opening up new possibilities mitigate negative impact traditional plastics. Microbes, including bacteria fungi, play crucial role in bioplastics by producing secreting extracellular enzymes, such as cutinase, lipases, proteases. However, these microbial enzymes sensitive extreme environmental temperature acidity, affecting their functions stability. To address challenges, scientists have employed protein engineering immobilization techniques enhance enzyme stability predict structures. Strategies improving substrate interaction, increasing thermostability, reinforcing bonding between active site substrate, refining activity being utilized boost functionality. Recently, bioengineering through gene cloning expression potential microorganisms, revolutionized biodegradation bioplastics.
