Plastic pollution has become a major global environmental threat due to the persistent nature of plastics like polyethylene, polypropylene, and PET, which resist natural degradation and accumulate in soil, water, and living organisms. Improper disposal results in microplastic formation, disrupting ecosystems and endangering human health. An emerging eco-friendly solution involves the use of plant growth-promoting rhizobacteria (PGPR) and other microbes capable of biodegrading plastics. These microorganisms produce enzymes such as PETase, laccase, and cutinase that break complex polymer chains into simpler, nontoxic compounds like carbon dioxide, water, and biomass. Notably, species such as Pseudomonas, Bacillus and Aspergillus not only degrade plastics but also enhance soil fertility and plant growth by producing growth-promoting substances. In this article we understand the dual action of microbes which supports both waste reduction and environmental restoration. Even though microbial degradation is often slow and may yield intermediate products, advancements in enzyme and genetic engineering, microbial consortia, and bioreactor technologies are improving its efficiency.
