Biodegradation of polymeric contact lenses: A comprehensive review of biological activity
AI summary Read the abstract
This review examines how microorganisms and enzymes break down polymeric contact lenses, which contribute to plastic pollution when improperly disposed of. Millions of discarded lenses enter water systems annually, fragmenting into microplastics that threaten aquatic ecosystems. Understanding the biological degradation processes could help develop more sustainable lens materials and better disposal methods.
Polymeric contact lenses are widely used for vision correction but contribute to significant environmental challenges due to their non-biodegradable nature and improper disposal, which exacerbates the growing problem of plastic pollution. Millions of discarded contact lenses enter landfills and water systems annually, where they break down into microplastics, posing threats to aquatic ecosystems and human health. This review explores the biological processes involved in the degradation of these lenses, with a focus on the roles of microorganisms, enzymes, and environmental factors such as temperature, pH, and humidity. Understanding how these factors influence the breakdown of polymer chains offers valuable insights into developing sustainable disposal methods and environmentally friendly materials. By comprehensively examining the enzymatic mechanisms of contact lens degradation, this review aims to propose green technologies for polymer waste management and highlights the urgent need for multidisciplinary efforts to mitigate the environmental impact of polymeric lenses, thereby advancing the global agenda for environmental sustainability.

Microplastic pollution: A global perspective in surface waters, microbial degradation, and corresponding mechanism
AI summary Read the abstract
This review provides a global overview of microplastic pollution in surface waters and examines the potential for microbial degradation as a remediation strategy. Researchers summarize evidence that certain bacteria, fungi, and algae can break down various types of microplastics, though degradation rates depend heavily on environmental conditions. The study highlights that while microplastics are now found in virtually every environmental niche, biological approaches to breaking them down are still in early stages of development.

Recent advances in biodegradation of emerging contaminants - microplastics (MPs): Feasibility, mechanism, and future prospects
AI summary Read the abstract
This review explores biological approaches to breaking down microplastics, including using bacteria, fungi, and enzymes. While some organisms can partially degrade certain plastic types, the process is slow and incomplete compared to the scale of pollution. The research is promising for future cleanup efforts but shows that biodegradation alone cannot yet solve the microplastic contamination problem.
