Introduction

Plastic pollution has emerged as a global environmental challenge, with polystyrene being a major contributor due to its widespread use and resistance to natural degradation processes [1]. Addressing the issue of polystyrene waste requires effective solutions, and recent advancements in polystyrene biodegradation research hold great promise [2-4]. This short communication aims to provide an overview of polystyrene biodegradation [5], including the mechanisms involved [6], recent studies, challenges, opportunities, and future directions.

Overview of Polystyrene Biodegradation: Biodegradation, the natural breakdown of materials by living organisms, offers a sustainable approach to managing plastic waste. However, the complex structure and inherent resistance of polystyrene pose challenges to its biodegradation. Recent research has focused on exploring microbial degradation [4,5], enzymatic breakdown [7], and abiotic degradation [8] as potential mechanisms for polystyrene biodegradation [9].

Mechanisms of Polystyrene Biodegradation: Microbial degradation of polystyrene involves the discovery of unique microorganisms capable of utilizing this polymer as a carbon source [3]. These microorganisms produce enzymes that facilitate the breakdown of polystyrene chains, leading to the release of simpler organic compounds. Enzymatic breakdown, specifically the action of enzymes like lipases and peroxidases, has shown promise in enhancing polystyrene biodegradation [10]. Additionally, abiotic degradation methods, such as chemical treatments and physical methods, have been explored to accelerate the breakdown of polystyrene [8].

Recent Studies on Polystyrene Biodegradation: Several studies have reported significant advancements in polystyrene biodegradation. Microbial strains, such as Pseudomonas spp. and Bacillus spp., have been identified for their ability to degrade polystyrene [11,12]. Enzymes like cutinizes and laccases have demonstrated their effectiveness in breaking down polystyrene molecules [13]. Moreover, innovative experimental setups and conditions have been developed to optimize biodegradation processes [5,6]. However, the utilization of polystyrene microbeads to discover the degradation of microorganisms was still under exploration by scanning electron microscopy.

Challenges and Opportunities: While polystyrene biodegradation shows promise, it also presents challenges. Environmental considerations and potential risks associated with the release of byproducts during degradation need to be carefully evaluated [14]. Additionally, scalability and feasibility for largescale waste management require further exploration. However, the byproducts of polystyrene biodegradation, such as organic acids and monomers, offer potential applications in the production of value-added products [15].

Future Directions and Outlook: To harness the full potential of polystyrene biodegradation, future research should focus on identifying key areas for improvement and collaboration between scientists, policymakers, and industry stakeholders [16,17]. This multidisciplinary approach can facilitate the development of sustainable waste management practices and the integration of polystyrene biodegradation within a circular economy framework [18,19].

Concluding Remarks

Polystyrene biodegradation holds promise as a viable solution for managing plastic waste. Recent research has shed light on the mechanisms involved, showcased successful biodegradation of polystyrene, and identified areas for further exploration. The challenges of environmental impact, scalability, and feasibility can be addressed through collaborative efforts. By embracing polystyrene biodegradation as a sustainable approach, this will take significant strides towards mitigating the environmental impact of plastic waste and moving towards a more sustainable future.
