The Us's Plastic Waste Problem: A Comprehensive Overview

Plastic waste is a significant environmental concern, with an estimated 350 million tons generated globally each year. The United States, as one of the world's largest consumers of plastics, plays a substantial role in this issue. In 2019, the US generated an estimated 73 million metric tons of plastic waste, which equates to roughly 220 kilograms per person. This is a notable increase from previous years, with 35.7 million tons produced in 2018 and 7.4 million tons in 1980. The mismanagement of plastic waste in the US, including low recycling rates and the export of plastic scrap, has led to pollution in both domestic and international ecosystems, impacting wildlife and human health.

Plastic waste generation in the US

Plastic waste is a significant environmental issue, polluting the land, oceans, air, and even food and human blood. The United States, as one of the world's largest consumers of plastics, is a major contributor to this problem. In 2018, the US generated 35.7 million tons of plastic waste, which was about 12.2% of municipal solid waste (MSW) generation. This figure had increased by 4.3 million tons since 2010, with plastics generation growing from 8.2% of MSW generation in 1990 to 12.2% in 2018. The containers and packaging category contributed the most to plastic waste tonnage, with over 14.5 million tons in 2018. This category includes bags, sacks, wraps, other packaging, PET bottles and jars, HDPE natural bottles, and other containers.

The US has seen a rapid increase in plastic waste generation over the past few decades. In 1980, the US produced 7.4 million tons of plastic waste, and by 2018, this number had increased five-fold to 35.7 million tons. This increase in plastic waste generation is not solely due to domestic consumption but also the illegal dumping and inadequate management of exported plastic scrap. The US is the second-largest exporter of plastic scrap globally, and when this exported material is not properly managed in the receiving country, it contributes to the environmental inputs of plastic waste generated in the US.

In 2019, US plastic waste generation was estimated at 73 million metric tons, corresponding to more than 220 kilograms per inhabitant. This was roughly five times the global average per capita plastic waste generation. The recycling rate of plastic waste in the US has been low, with only 5-6% of plastic waste recycled in 2021, according to a report by environmental groups Beyond Plastics and The Last Beach Cleanup. About 85% of plastic waste went to landfills, 10% was incinerated, and the rest was exported. The low recycling rate is attributed to a "decades-long misinformation campaign to perpetuate the myth that plastic is recyclable," as stated by Judith Enck, the president of Beyond Plastics.

The US's plastic waste problem has significant environmental and health impacts, with plastic pollution contaminating all major ecosystems on the planet. There is also growing concern about its potential impacts on wildlife and human health, as smaller and more widespread plastic particles are identified in both natural and built environments. Large amounts of plastic waste leak into the ocean every year, contributing to the death of thousands of sea mammals and fish. Plastic pollution in the oceans has also been identified as the main cause of frustration with the US recycling system.

Plastic waste exports from the US

The United States exported around 920 million pounds of scrap plastic in 2023, a decrease of 4.6% compared to 2022. The leading destinations for US plastic scrap exports in 2023 were neighbouring countries Canada and Mexico, which together accounted for more than half of exports that year. Asian countries such as India, Malaysia, and Vietnam received the second-largest share of US plastic scrap exports.

Until 2017, China was the primary destination for US plastic waste until a total ban on recovered plastic imports was imposed in January 2018. Despite the ban, the US continues to export plastic waste overseas, often to poorer countries with poor waste management, even though most countries have agreed not to accept it. The US was one of the few countries that did not ratify the global ban.

Data from the US Census Bureau shows that in 2018, the US exported about one-third of its recycling, or 1.07 million tons of plastic waste, with 78% going to countries with poor waste management. These countries, such as China, India, Malaysia, and Indonesia, lack the infrastructure and regulations to effectively and sustainably sort, process, and recycle plastic waste into new materials.

The US has bilateral and multilateral agreements with a few countries, including member countries of the Organization for Economic Cooperation and Development (OECD), regarding the transboundary movement of non-hazardous plastic scrap and waste. However, some countries may not allow trade with the US in Basel-controlled non-hazardous plastic scrap.

Plastic waste imports to the US

The United States has been a major exporter of plastic waste, with 1.07 million tons exported in 2018, about one-third of its recycling. However, following China's ban on plastic waste imports in 2017, the US has had to redirect its plastic waste exports to other countries, primarily in Southeast Asia, such as Malaysia, Vietnam, Thailand, and Indonesia. These countries have also become overwhelmed by the large amounts of plastic waste they receive, not only from the US but also from other developed countries like Canada, Japan, and Germany.

In 2024, Canada was the leading destination for scrap plastic exports from the US, with 154 thousand metric tons. Mexico was the second-largest importer, with 76.2 thousand tons. China's ban on plastic waste imports led to a significant decrease in US plastic waste exports, from about 1.4 million tons to 0.6 million tons. California remained the top exporter within the US, and South Carolina exhibited the highest per capita exports.

Internationally, there have been efforts to curb the trade in plastic waste. In May 2019, 187 countries agreed to restrict the international trade in plastic scrap and waste under the Basel Convention, which came into effect on January 1, 2021. This convention requires prior written consent from the importing country for most plastic scrap and waste shipments. However, despite this agreement, the US has continued to ship plastic waste overseas, particularly to poorer countries.

The US's reliance on exporting plastic waste to other countries highlights the lack of infrastructure and capacity within the US to manage its own plastic waste. The low recycling rate of 8.7% in 2018, compared to a global average of 9% and 30% in some European countries, indicates the need for stronger national regulatory actions to stimulate plastic recycling in the US.

Plastic waste recycling rate in the US

The United States is one of the world's largest consumers of plastics, with plastic use in the country more than tripling since the 1980s. In 2019, US plastic waste generation was estimated at 73 million metric tons, corresponding to more than 220 kilograms per inhabitant. This was roughly five times the global average per capita plastic waste generation. With plastic demand showing little sign of slowing, US plastic waste generation is projected to surpass 140 million metric tons by 2060.

The US has a significant problem with plastic waste, which is a major contributor to the growing global plastic waste crisis. Plastic waste has numerous negative environmental and health impacts, with the most concerning being its impact on marine life. Large amounts of plastic waste leak into the ocean every year, contributing to the death of thousands of sea mammals and fish. Plastic pollution in the oceans is also the main cause of frustration with the US recycling system. Some of the most common plastic waste items found on US beaches include cigarette butts, plastic bottle caps, and food wrappers.

The US Environmental Protection Agency (EPA) measures the generation, recycling, composting, combustion with energy recovery, and landfilling of plastic materials in municipal solid waste (MSW). The containers and packaging category had the most plastic tonnage at over 14.5 million tons in 2018. This category includes bags, sacks, wraps, other packaging, polyethylene terephthalate (PET) bottles and jars, high-density polyethylene (HDPE) natural bottles, and other containers.

The recycling rate for PET bottles and jars was 29.1% in 2018, and the rate for HDPE natural bottles was 29.3% in 2018. However, the overall recycling rate for plastic waste in the US is low, estimated at 8.7% in 2018 and between 5-6% in 2021. In contrast, the recycling rate for paper was 66% in 2020. This indicates that the US recycling system struggles specifically with plastic waste.

Environmental impact of US plastic waste

The United States is one of the world's largest consumers of plastics, with plastic use in the country more than tripling since the 1980s. In 2019, US plastic waste generation was estimated at 73 million metric tons, corresponding to more than 220 kilograms per inhabitant. This was roughly five times the global average per capita. With plastic demand showing little sign of slowing, US plastic waste generation is projected to surpass 140 million metric tons by 2060.

The environmental impact of plastic waste from the US is significant. Plastic waste has numerous negative environmental and health consequences, with impacts on marine life being particularly concerning. Large amounts of plastic waste leak into the ocean each year, contributing to the death of thousands of sea mammals and fish. Plastic pollution in the oceans also has a detrimental effect on marine habitats and natural processes, reducing ecosystems' ability to adapt to climate change and directly affecting millions of people's livelihoods, food production capabilities, and social well-being.

The persistence of plastic pollution is another critical issue. Research indicates that plastic pollution can take between 100 and 1,000 years or more to decompose, depending on environmental conditions. During this extended period, plastic pollution can fragment into smaller pieces, known as microplastics, which have been found in every ecosystem on the planet, from the Antarctic tundra to tropical coral reefs. Microplastics have even been detected in human livers, kidneys, and placentas, raising concerns about potential harm to human health.

The US contributes to plastic waste through exports and imports. In 2018, the US generated 35.7 million tons of plastic waste, with only 3 million tons recycled, resulting in a recycling rate of 8.7%. While the recycling rate for specific types of plastic containers, such as PET bottles and jars, was higher at 29.1%, the overall low recycling rate contributes to the environmental impact. Additionally, the US exports and imports plastic waste, which can lead to pollution in other countries if not properly managed.
