Every year, 52.1 million metric tons of plastic waste are either discarded into the environment or openly burned without proper management. Because of inadequate collection, recycling, and disposal systems, this waste has become one of the leading sources of pollution affecting soil, water, air, and natural ecosystems. The figures, published in a Nature study by Cottom et al., illustrate the scale of one of the world's most serious environmental challenges.
According to the study, the global average of unmanaged plastic waste is 7.6 kilograms per person annually. Unmanaged waste refers to plastic that is either dumped into the environment or burned in the open without meeting environmental standards. Such disposal methods release toxic pollutants while introducing significant quantities of microplastics into water resources, soil, and the food chain.
Countries vary widely in their per capita generation of unmanaged plastic waste. At the lowest end of the scale, some countries produce less than 0.5 kilograms per person annually, typically benefiting from advanced waste management infrastructure, organized collection systems, source separation, modern recycling technologies, and strict environmental regulations.
A second group generates 0.5 to 5 kilograms per person each year. Although plastic consumption may be relatively high in these countries, efficient waste management prevents most plastic waste from entering the environment.
Iran falls into the category of countries generating 5 to 10 kilograms of unmanaged plastic waste per person annually, indicating a moderate position compared with global levels while highlighting considerable room for improving waste management, expanding recycling, and reducing plastic leakage into the environment.
By contrast, some countries generate 10.1 to 15 kilograms per person annually, while those in the most critical category exceed 15 kilograms. These countries often face inadequate waste collection systems, limited recycling capacity, rapid urbanization, financial constraints, and inefficient municipal waste management.
Environmental experts stress that differences among countries are not determined solely by plastic consumption. The effectiveness of waste collection, source separation, recycling infrastructure, sanitary landfills, enforcement of environmental regulations, and public participation are the key factors influencing the volume of unmanaged plastic waste.
Plastic discarded into the environment gradually breaks down into microplastics that contaminate water supplies, soil, and food products, posing serious risks to both human health and wildlife. Open burning of plastic waste also releases toxic compounds and greenhouse gases, degrading air quality.
Experts recommend reducing single-use plastics, expanding recycling industries, investing in waste management infrastructure, promoting source separation, raising public awareness, and strictly enforcing environmental regulations as the most effective ways to curb the crisis. Without such measures, the continued growth of plastic waste could inflict irreversible damage on the environment, the economy, and public health.
