Plastic Waste Crisis: America's Yearly Plastic Pollution

Plastic waste is a significant environmental issue, polluting 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 growing global problem. In this paragraph, we will delve into the topic of plastic waste in America, exploring the staggering amounts of waste generated annually, the challenges of recycling, and the environmental consequences of this crisis.

Plastic waste generation

Plastic waste is a significant environmental issue, polluting 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 the growing global plastic waste problem. The amount of plastic waste generated in a country correlates with its population size. California, Texas, and Florida, the three most populous states in the US, also have the largest amount of landfilled plastic waste.

In 2016, the US generated 42 million metric tons of plastic waste, or 286 pounds per person, and was the largest generator of plastic waste of any country in the world. In 2019, the US produced 73 million metric tons of plastic waste, corresponding to more than 220 kilograms per inhabitant. This was roughly five times the global average per capita.

The US does not have the capacity to recycle all of its plastic waste domestically. In 2019, only 5% of plastic waste was recycled domestically, while 86% was left in landfills, and 9% was combusted. The US exports large volumes of plastic waste to other countries, including Canada, Mexico, and developing nations in Asia and Africa. However, the US's plastic waste exports have decreased in recent years, from 1.84 million tons in 2017 to 0.61 million tons in 2021, as countries like China have restricted foreign waste imports.

The primary data source on the generation of plastics in the US is the American Chemistry Council. In 2018, plastics generation was 35.7 million tons, which was 12.2% of Municipal Solid Waste (MSW) generation. The containers and packaging category had the most plastic tonnage, at over 14.5 million tons. Plastic food service items, such as disposable diapers, cups, utensils, trash bags, and medical devices, are often made of polystyrene, while trash bags are typically made of high-density polyethylene (HDPE) or low-density polyethylene (LDPE).

The US Environmental Protection Agency (EPA) has created a National Strategy to Prevent Plastic Pollution, with objectives including reducing pollution during plastic production, improving post-use materials management, and preventing trash and micro/nanoplastics from entering the environment.

Plastic waste exports

Plastic waste is a significant environmental issue in the United States, with the country generating an estimated 40 million tons of municipal plastic waste in 2021 alone. This figure has increased fivefold since 1980, and the US recycling system is struggling to keep up with the demand. As a result, the US exports large volumes of plastic waste to other countries, despite only accounting for 2% of the plastic waste generated.

The primary destinations for US plastic waste exports have historically been China, Canada, and Mexico. However, in 2018, China restricted foreign waste imports, causing US exports to the country to drop by 92%. This led the US to redirect its waste to other countries in Southeast Asia, including Vietnam, Malaysia, and Thailand. These countries have since also planned or implemented policies to ban or restrict scrap plastic imports, leaving the US with a growing stockpile of plastic waste.

The US has continued to export its plastic waste to poorer countries despite international agreements and laws restricting this practice. This has led to concerns about the environmental and health risks associated with poorly managed waste, which can leak into oceans, waterways, and landfills. There is increasing pressure to ban plastic waste shipping or improve the monitoring of dispatched materials.

To address the issue of plastic waste, some US cities have implemented taxes or bans on single-use plastic bags, and corporations have pledged to reduce or eliminate plastic production. However, the demand for plastics in the US shows little sign of slowing down, and the country's plastic waste generation is projected to surpass 140 million metric tons by 2060.

Plastic waste recycling

Plastic waste is a significant environmental issue in the United States, with the country generating large quantities of plastic waste each year. In 2018, the United States produced 35.7 million tons of plastic waste, which was a five-fold increase from 1980 when the country produced 7.4 million tons. The plastic waste generation in the US is projected to surpass 140 million metric tons by 2060. This waste primarily ends up in landfills, with an estimated 80%-85% of plastic waste being sent to landfill sites in 2021.

The US has struggled to recycle its plastic waste domestically due to a lack of recycling infrastructure and the water-intensive nature of the process. As a result, the US has historically exported large volumes of plastic waste to other countries, particularly China, which previously handled more than half of the US's recycled plastic waste. However, China and other Asian countries have recently restricted foreign waste imports, leading to a decline in US plastic waste exports from 1.84 million tons in 2017 to 0.61 million tons in 2021. This has put further strain on the already struggling US recycling system, with thousands of tons of waste plastic stranded in the country.

Despite the challenges, there are efforts to improve plastic waste recycling in the US. The Association of Plastic Recyclers (APR) works with companies across the plastics recycling value chain to promote packaging design, recycled content, policy education, and advocacy. APR has also released the APR Design® Guide to align packaging design and promote recyclable packaging across North America. Additionally, policymakers are seeking solutions to reduce plastic pollution and scale up plastics recycling, reduction, and reuse.

At the community level, some US states have implemented plastic waste reduction strategies, such as banning straws and flimsy plastic bags. However, the overall recycling rate in the US remains relatively low, with only 8.7% of plastic waste recycled in 2018 and a peak recycling rate of 9.5% in 2014. Even plastics that reach recycling facilities are not all recycled, with 30-36% of PET bottles wasted during the process. This highlights the need for new laws and policies to reduce plastic packaging and improve the recycling infrastructure in the US.

Plastic waste in oceans

In 2019, the U.S. generated an estimated 73 million metric tons of plastic waste, which is projected to surpass 140 million metric tons by 2060. The country's plastic waste generation has increased fivefold since 1980, with a staggering 35.7 million tons produced in 2018. This massive increase has outpaced the domestic recycling capacity of the U.S., leading to large volumes of plastic waste being exported to other countries, primarily Canada and Mexico. However, with many Asian countries restricting foreign waste imports, the U.S. is facing challenges in managing its plastic waste.

The plastic waste that ends up in the oceans comes from various land and ocean-based sources. Common plastic waste items found in U.S. beaches and oceans include cigarette butts, food wrappers, beverage bottles, straws, cups, plates, bottle caps, and single-use bags. These plastics can enter the ocean through streams, storm drains, and rivers, eventually accumulating in massive convergences that cover about 40% of the world's ocean surfaces.

The impact of plastic waste in oceans is devastating for marine life and ecosystems. Unlike other types of waste, plastic does not decompose, persisting indefinitely in the marine environment. Marine animals, such as seabirds, sea turtles, seals, and whales, ingest plastic or become entangled in it, leading to injuries and deaths. The Great Pacific Garbage Patch, located halfway between Hawaii and California, is a stark example of the magnitude of the problem, containing 100 million kilograms of plastic.

Addressing the plastic waste crisis in oceans requires urgent action on multiple fronts. It involves improving waste management practices, reducing plastic consumption, advocating for stronger regulations, and supporting local and global cleanup initiatives. The resolution "End Plastic Pollution: Towards an International Legally Binding Instrument," adopted by 175 countries in 2022, is a positive step towards addressing plastic pollution throughout its lifecycle. However, the slow nature of change and the continued increase in plastic production underscore the urgency of tackling this global epidemic.

Plastic waste in landfills

Plastic waste is a significant environmental issue in the United States, with the country generating millions of tons of plastic waste each year. In 2019, U.S. plastic waste generation was estimated at 73 million metric tons, corresponding to more than 220 kilograms per person. This was roughly five times the global average per capita. The U.S. does not have the capacity to recycle all of its plastic waste domestically and has been exporting large volumes to other countries. However, with many countries, including China, now restricting foreign waste imports, the U.S. is facing challenges in managing its plastic waste.

As a result, a significant portion of U.S. plastic waste ends up in landfills. In 2021, it was estimated that at least 80% of the 40 million tons of municipal plastic waste generated in the U.S. would be sent to landfill sites. This trend is expected to continue, with projections indicating that by 2050, approximately 12,000 metric tons of plastic waste will be in landfills or the natural environment.

The disposal of plastic waste in landfills has significant environmental and health implications. Plastic is challenging to degrade, and landfills can soon fill up, requiring new space for waste storage. Additionally, there is a risk of plastic leakage from landfills, particularly into nearby waterways, which can have detrimental effects on aquatic ecosystems. The degradation of plastic waste in landfills can also lead to the release of harmful volatile organic compounds (VOCs) and microplastics, impacting both the environment and human health.

To address these concerns, there is a growing focus on improving waste management practices and policies. Microbial degradation has been identified as a promising alternative for managing plastic waste. Certain microorganisms and enzymes can degrade synthetic plastics, offering a biological treatment technology. Additionally, limiting plastic use, reusing, and recycling are crucial in reducing plastic waste and its impact on the environment and human health.
