Plastic recycling is a complex and challenging issue, with significant environmental implications. While recycling is generally considered a positive step towards sustainability, the reality of plastic recycling is often less straightforward. The process of collecting, sorting, and recycling plastic can be expensive and time-consuming, and the presence of various plastic types, some of which are not recyclable, further complicates the matter. The United States, historically reliant on China as a market for its recycled plastic, has faced additional hurdles as China's demand decreased. This shift has led to the exploration of alternative destinations for US plastic scrap, such as Vietnam and Turkey, but it has also sparked discussions about the need to reduce plastic production and promote reusable alternatives.

Plastic scrap recycling rate in the US
Plastic scrap recycling rates in the US are low, with an overall recycling rate of 8.7% in 2018, according to the EPA. This rate has remained mostly stagnant since then, with some studies showing a recycling rate of just 5-6% in 2021. The US is one of the world's largest consumers of plastics, with plastic use more than tripling since the 1980s. This has made the country a major contributor to the global plastic waste problem.
The recycling rate varies depending on the type of plastic. For example, the recycling rate for PET bottles and jars was 29.1% in 2018, while the rate for HDPE natural bottles was 29.3% in the same year. However, these rates are still relatively small compared to the amount of plastic waste generated in the US. In 2019, plastic waste generation in the US was estimated at 73 million metric tons, which is roughly five times the global average per capita.
The US has also been exporting large amounts of plastic scrap to other countries, such as Vietnam, Turkey, and China. This has led to concerns about the uncontrolled and unlimited import of foreign recycling in these countries, impacting local recyclers and the environment.
To address the low plastic scrap recycling rate in the US, experts have suggested drastic cuts in plastic production, especially single-use plastics. There have also been calls for redesigning products to use less plastic and be more easily reused or recycled. Additionally, the EPA has released the "National Strategy to Prevent Plastic Pollution," which aims to eliminate the release of plastic pollution into the environment.

Plastic scrap recycling in Turkey
In 2018, China banned plastic waste imports, which led to an influx of plastic waste imports into Turkey. Between 2018 and 2020, the amount of plastic recycling Turkey imported from abroad soared from 159,000 to 439,000 tons, with the US and the EU being the largest exporters. Turkey's geographic proximity to and strong trade relations with the EU have made it a key destination for EU plastic waste exports. This has resulted in an "uncontrolled and unlimited" import of foreign recycling, leaving local recyclers without markets for the scrap they collect.
The impact of this influx of plastic waste is felt particularly by Turkey's scrap pickers, who number in the hundreds of thousands. These individuals travel the streets collecting scraps from houses and businesses to resell to factories for manufacturing into new products. Up to 80% of recyclable material in Turkey is collected by these individual waste pickers, who often work in hazardous conditions, exposed to extreme weather, medical waste, needles, and broken glass.
The health and environmental impacts of plastic recycling in Turkey have been documented in a report titled "It's as If They're Poisoning Us." The report highlights the consequences of the Turkish government's ineffective response to the health and environmental consequences of plastic recycling, including air pollutants and toxins that affect workers and people living near recycling facilities. Plastic recycling facilities in Turkey have also been associated with human rights violations, with workers, including children, exposed to toxic chemical additives that can cause serious health problems.
Despite the challenges, there are efforts to improve plastic scrap recycling in Turkey. Some companies, such as Vanden Recycling, offer plastic recycling services, including buying and selling recycled plastic. Turkey also has recycling companies like Polimerturk that procure clean plastic scrap and produce high-quality plastic granules. Additionally, Turkey has set a goal of achieving a 55% recycling rate for plastic packaging waste by 2023.

Plastic scrap recycling alternatives
Plastic scrap recycling is a growing problem in the United States, with a large amount of recyclable plastic piling up each month. While some companies are working to recycle plastic scrap, the issue is far from being solved. Here are some alternatives to traditional plastic scrap recycling that can help reduce plastic waste:
Extended Producer Responsibility (EPR) Plans
Several countries in Europe and Ghana are working to implement EPR schemes, which require producers of plastic packaging and bottles to provide funding to support the management of these materials after their initial use. While the impact of these schemes is currently limited, they have the potential to reduce plastic waste and improve recycling infrastructure.
Redesigning Products
Manufacturers can play a crucial role in reducing plastic scrap waste by redesigning their products to use less plastic and be more easily reused or recycled. This includes using refillable bottles, reusable packaging, and take-back services. Incremental changes, such as reducing the amount of plastic in products, can also help, but more significant changes, such as eliminating certain types of plastic, may be necessary to solve the pollution crisis.
Supporting Ethical Recycling Companies
Some companies, such as Scrap Management Inc. and Quincy Recycle, offer ethical and environmentally friendly alternatives for industrial plastic recycling. They work with businesses to divert plastic waste from landfills, reduce costs, and even provide fair market value for scrap plastic. Supporting and partnering with these companies can help promote more sustainable practices in the industry.
International Cooperation
Plastic scrap recycling is a global issue, and international cooperation is essential to finding solutions. Countries like China and Turkey have previously imported large quantities of plastic scrap from the US for recycling, but this has negatively impacted local recycling industries and led to environmental concerns. Working together to develop sustainable practices and ethical standards for the plastic scrap trading industry can help address this complex problem.
Public Awareness and Advocacy
Public awareness and advocacy play a crucial role in addressing plastic scrap recycling issues. Marine scientists, environmental engineers, and organizations like the 5 Gyres Institute are raising awareness about the limitations of recycling and the need for drastic cuts in plastic production, especially single-use plastics. This growing public awareness has already led to actions such as the United Nations Environment Assembly's resolution to work towards a global treaty to end plastic pollution.

Plastic scrap recycling issues
Plastic scrap recycling is a complex issue that involves economic, environmental, and social factors. One of the primary issues is the technical challenges posed by the recycling process. Plastic recycling is a mechanical process that involves sorting, grinding, washing, filtering, melting, and blending plastic materials. However, the countless combinations of synthetic chemicals and fossil fuel polymers in plastics create significant obstacles. Different types of plastics cannot be recycled together, and there is a lack of transparency about the chemicals used, making it difficult to separate and recycle plastics effectively.
Another issue is the limited capacity for plastic recycling. In the United States, for example, only about 8.7% of plastics were recycled in 2018, amounting to three million tons. This is due in part to the high cost of recycling compared to producing new plastic from virgin fossil fuels. Additionally, the diversity of raw materials used in plastic manufacturing complicates the recycling process, making it more expensive and impacting the quality of the recycled product. As a result, the demand for recycled plastics is increasing, but the supply is not meeting this demand.
The export of plastic scrap is another critical aspect of the issue. Countries like the United States have been exporting large quantities of plastic scrap to other nations, such as Vietnam, Turkey, and China. This has led to concerns about the uncontrolled and unlimited import of foreign recycling, impacting local recyclers and the environment in these importing countries. There is also a risk of increased incineration and landfilling of plastic waste in exporting regions, such as the EU, due to restrictions on importing plastic waste in some countries.
Furthermore, the recycling process itself can be polluting. Recycling facilities release microplastics and PFAS particles into waterways, contaminating water sources and potentially impacting human health. Recycled plastics may also contain elevated levels of toxic chemicals, including heavy metals, phthalates, and flame retardants, which can leach out and cause health issues. These concerns have led to calls for extended producer responsibility (EPR) plans, requiring producers of plastic products to provide funding for the management of these materials after their initial use.
To address these issues, experts advocate for a combination of solutions. Reducing the production of single-use plastics and redesigning products to use less plastic and be more easily recycled or reused are crucial steps. Additionally, replacing "unnecessary and problematic" plastics with more sustainable alternatives is essential. While recycling can play a role, it is not the sole solution, and improving recycling processes to minimise pollution and health risks is vital.

Plastic scrap recycling solutions
Plastic scrap recycling is a growing industry, with a particular focus on municipal solid waste (MSW). While the US does recycle some plastic scrap, it also exports a significant amount to other countries. In 2018, the US recycled 3 million tons of plastic, which equates to an 8.7% recycling rate. However, this rate varies depending on the type of plastic, with PET bottles and jars having a recycling rate of 29.1% in 2018, and HDPE natural bottles achieving a rate of 29.3% in the same year.
Despite these efforts, the US still sent 83,000 tons of plastic recycling to Vietnam in 2018. This export of plastic scrap is not limited to Vietnam, with Turkey also receiving large amounts of US plastic scrap, which has negatively impacted the local recycling industry.
To improve plastic scrap recycling, various solutions have been proposed:
- Extended Producer Responsibility (EPR) plans: These policies require producers of plastic products, such as bottles and packaging, to provide funding for the management of these materials after their initial use. This approach has been adopted by almost every country in Europe and is being explored by other nations like Ghana. However, the impact of EPR schemes is currently limited, as the primary contributors are "midstream" producers like bottlers and beverage manufacturers.
- Reducing plastic production: Marine scientist Marcus Eriksen and the 5 Gyres Institute assert that recycling and reuse alone cannot address the vast amount of plastic waste. They call for drastic cuts in the production of single-use plastics. This sentiment is echoed by the United Nations, which is working towards a global treaty to end plastic pollution.
- Redesigning products: Inger Andersen, executive director of UNEP, emphasizes the importance of product redesign to reduce plastic usage and enhance reusability and recyclability. This includes exploring alternatives to certain plastics, such as polyvinyl chloride (PVC), which breaks down into toxic components and cannot be recycled.
- Technological advancements: Startups like Scrapo Inc. aim to bridge the gap between buyers and sellers of plastic scrap, improving trust and efficiency in the trading industry.
Additionally, there are companies like Power Plastic Recycling and Scrap Management Inc. that specialize in plastic recycling services and the purchase of plastic scrap for processing.

Frequently asked questions
The US does recycle plastic scrap, but the amount recycled is relatively small. In 2018, the recycling rate for plastic was 8.7%. However, the recycling rates for specific types of plastic containers, such as PET bottles and jars, and HDPE natural bottles, were significantly higher, at 29.1% and 29.3%, respectively.
Plastic that is not recycled in the US is often incinerated, deposited in landfills, or washed into the ocean. Incineration can produce energy, but it also releases toxic emissions and ash, which can be hazardous to human health and the environment. Landfills also emit greenhouse gases and other pollutants, contributing to climate change and air pollution.
There are several challenges to recycling plastic in the US. Firstly, plastic is cheap and easy to produce, which can disincentivize recycling. Secondly, collecting and sorting plastic for recycling can be expensive, and there are thousands of different types of plastic, making it difficult to recycle them together. Finally, some types of plastic, such as polyvinyl chloride (PVC), cannot be recycled and break down into toxic components.
