The Us's Plastic Problem: A Global Environmental Concern

Plastic is an indispensable material in manufacturing, packaging, and construction due to its versatility, durability, and affordability. However, it has also become a significant environmental concern, with the flow of plastic into the ocean projected to nearly triple by 2040. The United States, in particular, generates more plastic waste than any other country, with 42 million metric tons produced in 2016 alone. This waste often ends up in landfills, contributing to global pollution levels and impacting marine life. While some plastic waste is recycled, the rate is relatively low, and a significant amount is shipped overseas to countries with ineffective waste management systems. As the world grapples with the growing challenge of plastic pollution, it is essential to address the role of the United States in contributing to this crisis and explore solutions such as reducing single-use plastics and improving recycling technologies.

Plastic waste in the US

Plastic waste is a significant issue in the US, with the country generating more plastic waste than any other. In 2016, the US produced 42 million metric tons of plastic waste, or 286 pounds per person. This figure contradicts the widely held belief that Asian nations are the primary contributors to global plastic pollution. While China, Indonesia, the Philippines, Thailand, and Vietnam have long been seen as the biggest polluters, the US's role in the global waste export system has been overlooked. The US exports large quantities of plastic waste to developing countries in Asia and Africa, with up to 1 million metric tons of US-generated plastic waste contributing to environmental pollution in other countries.

Plastic is a rapidly growing component of municipal solid waste (MSW). In 2018, the US produced 35.7 million tons of plastic, accounting for 12.2% of MSW generation. The containers and packaging category had the highest plastic tonnage, with over 14.5 million tons. This category includes bags, sacks, wraps, bottles, jars, and other containers made from various types of plastic resins. Plastic resins are also used in durable goods such as appliances, furniture, and batteries. The versatility, durability, and affordability of plastics have made them indispensable in manufacturing, packaging, and construction, supporting over a million jobs.

Despite the economic importance of plastics, their environmental impact is significant. Plastic waste is not just an environmental issue but also a waste management and land use problem, as landfills are closing in many areas. In 2019, 86% of plastic waste in the US was sent to landfills, with only about 5% being recycled. The low recycling rate is partly due to the challenges of recycling different types of plastic resins, contaminated plastics, and plastics with additives. However, there is a growing recognition of the need to reduce, reuse, and recycle plastics to address the problem. The US EPA has released a "National Strategy to Prevent Plastic Pollution," aiming to reduce pollution during production, improve post-use materials management, and prevent plastic trash and microplastics from entering the environment.

To address plastic waste effectively, a combination of design and reuse strategies, policy instruments, and new recycling techniques is necessary. Developing products that rely on specific plastics can encourage their sorting and collection, and advanced sorting technologies can increase the use of recycled materials. Creating less, improving recycling rates, and developing innovative packaging and delivery methods are crucial to reducing plastic waste. The American Chemistry Council, representing America's Plastic Makers, is working towards linking innovation with sustainability to make plastics more efficient and recyclable, aiming for 100% of US plastic packaging to be reused, recycled, or recovered by 2040.

Plastic recycling rates

The United States generates more plastic waste than any other country in the world. In 2016, the US produced 42 million metric tons, or 286 pounds per person, of plastic waste. A report by the US Environmental Protection Agency (EPA) found that in 2018, plastics generation was 35.7 million tons in the US, 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.

The recycling rate for plastic waste in the US is extremely low. In 2016, less than 10% of plastic waste in the US was collected for recycling, and the recycling rate was 8.7% in 2018. In 2021, the recycling rate for post-consumer plastic waste was even lower, at just 5-6%. This is in stark contrast to materials like paper, which had a recycling rate of 66% in 2020. The US Plastics Pact has set a target of recycling or composting 50% of plastic packaging by 2025.

The low recycling rates for plastic in the US are due in part to the fact that plastic recycling has always failed to reach meaningful levels. Even when millions of tons of plastic waste per year were counted as recycled when exported to China, the recycling rate never exceeded 10%. With China no longer accepting plastic waste, the US has struggled to find alternative solutions, and as much as half of its plastic waste is now sent to other developing nations in Asia and Africa.

The US EPA has released the "National Strategy to Prevent Plastic Pollution," which aims to eliminate the release of plastic pollution into the environment. The US Plastics Pact is also working towards a circular economy for plastic packaging, with 66% of its business Activators taking individual action to eliminate certain plastics. However, as of 2021, only 37% of plastic packaging placed on the market by US Plastics Pact Activators is reusable, recyclable, or compostable.

Plastic pollution in coastal environments

Plastic pollution is one of the most pressing environmental issues, threatening ocean health, marine species, food safety, human health, and coastal tourism, while also contributing to climate change. The United States is a top contributor to this crisis, ranking third among countries responsible for coastal plastic pollution.

The US generates the most plastic waste of any country globally, and its contribution to the pollution of coastal environments is significant. A 2020 study published in the journal Science Advances revealed that the US is a top source of coastal plastic pollution, with up to 1.5 million metric tons of plastics ending up in coastal environments within 50 km of a coastline. This proximity to the shore increases the likelihood of plastics entering the ocean by wind or through waterways.

The study, conducted by researchers from the Sea Education Association, DSM Environmental Services, the University of Georgia, and Ocean Conservancy, used 2016 data on plastic waste generation, the latest available at the time. It was found that 2-3% of all plastic waste generated in the US, amounting to between 0.91 and 1.25 million metric tons, was either littered or illegally dumped domestically. When combined with waste exports, the US contributed up to 2.25 million metric tons of plastics into the environment.

The high ranking of the US in coastal plastic pollution challenges the previous assumption that the country adequately manages its plastic waste. The large amount of plastic waste generated in the US, coupled with its practice of exporting scrap plastic, has resulted in the country outsourcing its plastic pollution problem to developing countries. This has led to contamination not only in the US but also in countries processing US waste for recycling, such as Malaysia and Indonesia.

To address this issue, the US needs to reduce its plastic waste production and improve its waste management practices. This includes investing in recycling technologies, collection programs, and more sustainable plastic alternatives. Individual actions, such as reducing single-use plastic consumption and properly disposing of plastic waste, can also help mitigate plastic pollution in coastal environments.

Plastic packaging and containers

The recycling rate for PET bottles and jars in the US was 29.1% in 2018, amounting to 910,000 tons. Meanwhile, the recycling rate for HDPE natural bottles, such as milk and water bottles, was slightly lower at 29.3%, or 220,000 tons. Overall, the US recycled nearly 2 million tons of plastic containers and packaging in 2018, which corresponds to 13.6% of the total generated.

However, the majority of plastic containers and packaging waste in the US ends up in landfills or the ocean. In 2018, 69% of plastic containers and packaging waste, or over 10 million tons, was landfilled. This contributes to the growing problem of plastic pollution, with plastic waste degrading the environment and harming marine life.

To combat this issue, various initiatives and policies have been proposed and implemented. These include plastic bans, taxes, and levies on plastic bags, which have shown success in some countries like Australia, which reduced its plastic bag usage by 80%. Additionally, redesigning products to increase recyclability and implementing policies to reduce plastic packaging pollution, such as take-back mandates and recycled content standards, can help increase plastic circularity and reduce plastic consumption.

The food and beverage industry, in particular, faces the challenge of reducing plastic waste. However, innovations like biodegradable packaging, reusable systems, and plastic-free shipping supply chains offer promising solutions.

Plastic waste by state

Plastic waste is a significant environmental issue, polluting land, oceans, air, and even food and human blood. As one of the world's largest consumers of plastics, the United States plays a major role in contributing to this global problem. The plastic waste generation in the US has increased over the years, with an estimated 73 million metric tons in 2019, corresponding to more than 220 kilograms per inhabitant. This was approximately five times the global average per capita.

The plastic waste generation in the US varies across states and is often correlated with population size. California, Texas, and Florida, being the three most populous states, also have the largest amount of landfilled plastic waste. New York, the fourth most populous state, manages its waste differently by shipping much of it outside the state.

The recycling rate of plastic waste in the US has been relatively low, with only about 5% of plastic waste recycled in 2019, while 86% was landfilled, and the rest was burned for energy recovery. The low recycling rate is attributed to various factors, including the challenges of recycling combinations of plastic resins, plastics with additives, and contaminated plastics. Additionally, consumer preferences for single-use plastics and low disposal fees in certain areas contribute to the issue.

To address the plastic waste problem, the US Environmental Protection Agency (EPA) has released the "National Strategy to Prevent Plastic Pollution," focusing on eliminating plastic pollution release into the environment. The EPA measures the generation, recycling, composting, combustion with energy recovery, and landfilling of plastic materials in municipal solid waste (MSW). In 2018, plastic generation was 35.7 million tons in the US, constituting 12.2% of MSW generation.

The containers and packaging category, including bags, sacks, wraps, bottles, and jars, had the most plastic tonnage within the MSW categories, with over 14.5 million tons in 2018. The recycling rates for specific types of plastic containers are more significant, with PET bottles and jars at 29.1% and HDPE natural bottles at 29.3% in 2018.

The US has also contributed to global plastic pollution by exporting waste to other countries, particularly those with ineffective waste management systems. Developing new recycling techniques and implementing policies to reduce plastic consumption and increase plastic circularity are essential steps in tackling the plastic waste crisis.
