Plastics and the environment: challenges, impacts, and pathways to sustainability.
Summary
This review pulls together existing research on how plastics are made, used, and thrown away, showing just how hard they are to get rid of once they enter the environment — often breaking down into tiny microplastic particles that can end up in our water, food, and even our bodies. The good news: the authors point to real solutions already in motion, like better recycling technology (including AI-powered sorting), smarter policies, and new biodegradable materials, all aimed at cutting down our plastic footprint. The takeaway for you: reducing plastic waste isn't just about the planet — it's increasingly tied to limiting your own exposure to plastic particles in everyday life
Plastics have revolutionized modern life due to their versatility, durability, and low production costs. However, their persistence in the environment has become one of the most pressing global challenges. This review looks closely at the full life cycle of plastics from polymerization and processing to manufacturing and use across different industries. It also critically examines the environmental impacts of plastic waste. Special attention is given to the two main categories of plastics, thermoplastics and thermosets, and the unique challenges they pose for waste management and recycling. We discuss common processing methods such as injection molding, extrusion, blow molding, and additional operations, with a focus on how they influence material recovery and sustainability efforts. The review also explores various strategies to reduce plastic pollution, including cutting plastic use at the source, promoting reusable alternatives, advancing mechanical and chemical recycling, and developing new biodegradable polymers. Furthermore, it highlights the role of strong policy actions, increased public awareness, and artificial intelligence (AI)-driven recycling systems in moving toward a circular plastic economy. By combining innovation in materials science with environmental responsibility and socioeconomic strategies, this review identifies key pathways for sustainable plastic management and stresses the need for interdisciplinary collaboration to address the global plastic crisis.
