Plastic recycling in the US is a complex issue with many challenges. While Americans generate a significant amount of plastic waste, the recycling rate remains low, with only about 8-10% of plastic being recycled. The rest often ends up in landfills, is incinerated, or exported to other countries, particularly in Southeast Asia, for recycling. However, there are concerns about the environmental and social impacts of these exports, as well as the contamination of recyclables and the lack of infrastructure to support effective plastic recycling domestically. While most Americans want to recycle, there is confusion about what can be recycled and how to do it properly, highlighting the need for better education and infrastructure to improve plastic recycling rates in the country.

What You'll Learn
Plastic recycling rate in the US
Plastic recycling rates in the US are low, with only 5-6% of plastic recycled in 2021, and 85% of plastic waste ending up in landfills. This is in part due to a "decades-long misinformation campaign to perpetuate the myth that plastic is recyclable", according to Judith Enck, the president of Beyond Plastics. Enck also attributes consumer confusion to the three-arrow recycling symbol, which is misleading as most municipalities only recycle certain types of plastics. When consumers place non-recyclable plastics into recycling bins, loads become contaminated and are usually sent to landfills or incinerated.
The US exported large amounts of plastic waste to Asia, taking advantage of the empty shipping containers that had transported goods from China to the US. However, countries such as China have begun to refuse America's waste, and the US does not have the infrastructure to recycle all of its own plastic.
The US Environmental Protection Agency (EPA) has released the "National Strategy to Prevent Plastic Pollution", which aims to eliminate plastic pollution released into the environment. The EPA's National Recycling Strategy identifies actions needed to address the challenges in the US recycling system, including the development of products to assist communities in improving their recycling programs.
While recycling is an important economic driver, creating jobs and tax revenues, the US recycling system is facing challenges such as consumer confusion over what materials can be recycled and how, and contamination of recyclables. Plastic is particularly challenging to recycle as it is often contaminated by other materials, and companies are reluctant to buy recycled plastic unless it is pure.

Plastic recycling contamination
In the US, the issue of plastic recycling contamination is complex and multifaceted. While many Americans make an effort to recycle, the country's recycling system is broken, with much of the waste placed in recycling bins not actually being recyclable. This is due in part to unclear messaging on bins, leading to non-recyclables being mixed up with recyclables. Additionally, there is a lack of infrastructure to properly process and recycle certain materials, such as plastic straws, bags, eating utensils, yogurt containers, and takeout containers, which often end up being incinerated, deposited in landfills, or washed into the oceans.
The US has also been criticised for exporting its plastic waste to developing countries with poor environmental regulations, such as Bangladesh, Laos, Ethiopia, and Senegal. These countries offer cheap labour for the dirty and labour-intensive process of recycling, but the consequences for public health and the environment are dire. This practice came to light after China's "National Sword" policy banned waste imports and set strict standards for the plastic it would accept, causing a crisis in the US as much of its "recyclable" plastic had nowhere to go.
To improve plastic recycling in the US and reduce contamination, clear and effective labelling on bins is essential. Additionally, there is a need for better education on what materials can and cannot be recycled, and how to properly clean and prepare recyclables. However, ultimately, the responsibility for reducing plastic pollution lies with plastic manufacturers and distributors, who must be held accountable and transition to more sustainable practices.

Plastic recycling infrastructure
Plastic recycling in the US is a challenging and complex issue. While there is public support for recycling, the country's infrastructure has not kept pace with the increasing amounts of waste generated. The US exported large quantities of plastic waste to China for many years, and this has hindered the development of domestic recycling infrastructure. However, China no longer accepts lower-grade plastics, and the US now faces challenges in dealing with its plastic waste.
The US Environmental Protection Agency (EPA) has recognised the need for improvement in the country's recycling infrastructure. It has developed tools such as the Recycling Infrastructure and Market Opportunities Map, which provides data and information on recycling infrastructure and markets. The EPA has also announced funding for recycling, reuse, and waste prevention programs, aiming to enhance the system and increase recycling rates.
The current plastic recycling process in the US involves several steps. First, materials are collected and transported to processing facilities, where they are sorted and cleaned of contaminants. Glass and plastic may be sent to specific plants for further processing. After that, the cleaned recyclables are transported to milling or manufacturing facilities to be remade into new products. However, contamination is a significant issue, as plastic often comes into contact with other materials, reducing the quality and recyclability of the collected plastic.
To improve plastic recycling infrastructure in the US, a multi-entity collaborative effort is required. Standardised metrics and methodologies are needed to track progress and performance effectively. Additionally, public education is crucial to ensure people understand what, how, and where to recycle. Furthermore, technological advancements, such as mechanical and chemical recycling, can enable the recycling of almost all plastics.

Plastic recycling exports
Plastic recycling in the US has been described as "broken", with a lack of progress in recent years. The US exports large amounts of plastic waste to other countries, particularly developing countries with poor environmental regulations and cheap labour, such as Bangladesh, Laos, Ethiopia, and Senegal. These countries often mismanage their own plastic waste and are overwhelmed by the influx of foreign waste.
In the past, the US shipped much of its plastic waste to Asia, particularly China, due to the low shipping costs of returning empty containers that had been used to transport goods from China to the US. However, in 2018, China introduced a ban on the import of plastic waste, causing the US to seek alternative destinations for its plastic waste exports. Since the China ban, the US has been exporting more than 1 million tons of plastic waste annually to countries that are already struggling to manage their own waste.
Canada is now the leading destination for US plastic scrap exports, receiving 154 thousand metric tons in 2023. Mexico is the second-largest destination, importing 76.2 thousand tons of plastic scraps from the US in the same year.
The US's plastic exports have had significant environmental and social ramifications, with US recyclables often ending up in landfills, incinerated, or washed into the ocean, both domestically and in the recipient countries. The plastic waste trade has also been associated with toxic emissions from waste-to-energy plants and the contamination of recyclables due to improper disposal methods.
Despite the challenges, recycling is an important economic driver in the US, creating jobs and tax revenues. However, the US's recycling infrastructure needs to improve to enhance environmental and community benefits, address contamination issues, and provide clearer guidelines on recycling practices to consumers.

Plastic recycling solutions
Plastic recycling in the United States is a complex issue with a range of challenges and potential solutions.
One significant issue is the contamination of recyclables, often due to items being placed in the wrong bin or dirty food containers being included. This can render large batches of material unrecyclable and is a particular problem with single-stream recycling, where all recyclables are placed in the same bin. Plastic recycling is especially challenging due to contamination by other materials, and companies are often reluctant to buy recycled plastic unless it is very pure. Certain items, such as plastic straws, bags, utensils, and yogurt containers, are also difficult to recycle and often end up being incinerated, deposited in landfills, or washed into the ocean.
Another issue is the lack of infrastructure to support recycling. Many Americans want to recycle but struggle to understand what, how, and where to recycle different materials, leading to recyclables being thrown away or contaminated with non-recyclables. The US recycling system has not kept pace with the amount and variety of waste being generated, and there is a need for more consistent measurement methodologies to track progress and set effective goals.
To address these issues, several solutions can be implemented:
- Standardization and Education: Standardized metrics and educational initiatives can help Americans better understand what materials can be recycled, how to recycle them properly, and where to recycle different materials. This can reduce contamination and ensure more effective recycling practices.
- Infrastructure Development: The US recycling infrastructure needs to be expanded and modernized to handle the increasing volume and diversity of waste. This includes investing in more advanced recycling facilities, such as glass beneficiation plants and plastics reclaimers, to improve the recycling process.
- Collaboration and Policy Changes: Multi-entity collaboration between federal, state, local governments, private businesses, and non-profit organizations is essential. Congress can pass laws to encourage plastic companies to adopt more environmentally friendly practices and support the development of a robust domestic recycling industry.
- International Cooperation: The US can work with other countries to develop sustainable solutions for plastic waste management. This includes responsible waste disposal and processing, as well as reducing the export of plastic waste to developing countries with poor environmental regulations.
- Encouraging Reusable Alternatives: Promoting reusable options over single-use plastics can significantly reduce plastic waste. Incentivizing companies to offer reusable or biodegradable alternatives can help shift consumer preferences and reduce the demand for single-use plastics.
- Technological Innovations: Investing in research and development for new recycling technologies can improve the efficiency and effectiveness of plastic recycling processes, making it more economically viable and environmentally friendly.

Frequently asked questions
According to the EPA, of the 267.8 million tons of municipal solid waste generated by Americans in 2017, only 94.2 million tons were recycled or composted, and only 8% of plastics were recycled. The recycling rate of PET bottles and jars was 29.1% in 2018, and the rate for HDPE natural bottles was 29.3% in 2018. However, other sources claim that the US only recycles about 5% of its plastic waste.
Plastic recycling in the US faces several challenges. Firstly, there is confusion among consumers about what materials can be recycled and how to recycle them properly, leading to contamination of recyclables and low recycling rates. Secondly, the US has limited infrastructure and capacity to process and recycle all the waste plastic it generates, resulting in large amounts of plastic waste being exported to other countries.
In the past, the US exported much of its plastic waste to China for recycling. However, following China's ban on most US plastic exports in 2017, the US has been exporting its plastic waste to other Southeast Asian and developing countries, including Thailand, Malaysia, Bangladesh, Laos, Ethiopia, and Senegal. These countries offer cheap labor and limited environmental regulations, but they are often overwhelmed by the influx of plastic waste, leading to improper disposal and negative environmental and social impacts.
