Global Plastic Production, Environmental Impacts, and Sustainable Remediation Strategies: A Comprehensive Review

Abstract

Plastics have become indispensable commodities in modern society, with global output topping 370 million tons per year. However, their persistence and mismanagement have resulted in serious environmental and health consequences. This paper provides a comprehensive overview of plastic manufacturing trends from 1950 to 2025, focusing on the exponential development in worldwide output and the associated increase in trash generation. The research addresses the ecological, biological, and human health effects of plastics and microplastics, using quantitative data. Various remediation options, including as mechanical and chemical recycling, biodegradation, and the development of bioplastics, are critically reviewed. Policy initiatives, circular economy models, and global sustainability frameworks are all considered. The research concludes that comprehensive global policies combining innovation, legislation, and education are critical for transitioning to a sustainable plastic economy.

6. POLICY, EDUCATION, AND CIRCULAR ECONOMY

Effective plastic management necessitates robust policy frameworks. The EU Directive (2019/904) and India's 2022 ban on single-use plastics are significant legislative achievements [14, 22]. Public participation, awareness campaigns, and education are critical for behavioural change [23]. Circular economy approaches, which emphasize reuse, recycling, and material innovation, serve as the cornerstone for sustainable plastic management [15].

7. FUTURE PERSPECTIVES

Future research should focus on cost-effective biodegradable polymers, scalable recycling systems, and enhanced microplastic detection [17]. Artificial intelligence in garbage sorting, blockchain for traceability, and worldwide recycling code standardization could all help to hasten the circularity shift [24].

8. CONCLUSION

• By 2025, global plastic production is expected to reach about 400 Mt per year, with packaging accounting for the majority.
• Only 9% of plastic trash gets recycled, with the rest being burnt or landfilled.
• Plastic pollution in the oceans and on land is getting worse, endangering ecosystems and human health.
• Mechanical recycling is dominant but insufficient for achieving global circularity.
• Promising developments in chemical and enzymatic recycling require large-scale demonstrations.
• Bioplastics have limitations in performance and deterioration, making them not a universal answer.
• Policy frameworks like EPR and recycled-content standards enhance accountability but require worldwide uniformity
• Data transparency and standardized lifecycle metrics are critical for effective monitoring.
• International cooperation under the Global Plastics Treaty will be pivotal for systemic transformation.
• Integrated technological, economic, and behavioural interventions are essential to transition toward a sustainable plastic future.
