The Us's Plastic Pellet Production: A Startling Overview

Plastic pellets, also known as pre-production microplastics, are the building blocks for nearly every plastic product. They are produced by petrochemical companies and transported to plastic manufacturing facilities where they are melted and shaped into the final product. Plastic pellets are a major source of plastic pollution in the ocean and are often mistaken by marine animals for food. They can absorb toxins from water and transfer them to the marine food web, increasing the risk of adverse effects on wildlife and humans. The United States is one of the biggest producers and users of plastic products, and plastic pellet pollution has been documented in the country since 1972.

Plastic pellets are the second-largest source of microplastic pollution in oceans

Plastic pellets, also known as nurdles, are the building blocks of most plastic items. These pellets are used in manufacturing and moulding plastic into countless products, from bottles to bags. However, they are also a significant contributor to plastic pollution in our oceans. In fact, plastic pellets are the second-largest source of microplastic pollution in the oceans.

Microplastics are plastic particles smaller than 5 millimetres, or about the size of a pencil eraser. They come from a variety of sources, including larger plastic pieces that break down into smaller fragments. Plastic pellets, being small in size, can easily spill into waterways and accumulate in the ocean. According to Time Magazine, billions of nurdles are lost from production and supply chains annually, ending up in our oceans.

The issue of plastic pellet pollution is not new. A 1972 study published in the journal Science found an abundance of plastic pellets in the coastal waters of southern New England. The EPA raised concerns about this issue to Congress in the early 1990s, reporting high concentrations of pellets in the world's oceans and in harbors across the United States. Despite these early warnings, plastic pellet pollution continues to be a pressing environmental concern.

The impact of plastic pellet pollution is far-reaching. Once in the environment, these pellets persist and break down into even smaller microplastics. Due to their small size, they are often mistaken for food and ingested by aquatic life, birds, and other animals, leading to potential health risks. The chemical composition of these pellets can also pose threats to wildlife. For example, pellets found near the Formosa plastics plant in Texas had mercury sticking to them, raising concerns about toxic contamination.

To address this issue, some companies have joined campaigns such as Operation Clean Sweep (OCS) Blue, where they voluntarily disclose information about the number of plastic pellets shipped, spilled, recovered, or recycled. However, this data is often shared confidentially, and there is limited information on the extent of nurdle pollution originating in the United States. Nonetheless, with robust pellet management plans and procedures, it is estimated that plastic pellet pollution can be reduced by up to 80% by 2040.

Pellets are produced by petrochemical companies and transported to manufacturing facilities

Plastic pellets, also known as nurdles, are small, granular pieces of plastic that serve as raw material for manufacturing a wide array of products. They are produced by petrochemical companies through a process called plastic pelletizing or pelletization, which involves cutting plastic scraps into tiny pieces and melting them. The molten plastic is then extruded through a die to form cylindrical pellets. These pellets are versatile and can be used to create various products, from everyday items to critical components in manufacturing, such as packaging materials, automotive parts, electronic devices, medical equipment, and construction materials.

The production of plastic pellets has significantly contributed to the increasing plastic waste globally. Between 1950 and 2015, the world generated over 6.3 billion metric tons of plastic waste. Despite initiatives like Operation Clean Sweep, which aims to reduce pellet spills, plastic pollution remains a critical international environmental crisis. Plastic pellets, whether used or unused, end up in oceans and other water bodies, contributing to microplastic pollution.

Petrochemical companies, such as Formosa, play a significant role in producing plastic pellets. Formosa, for instance, manufactures one trillion pellets every day. These pellets are then transported to manufacturing facilities to be molded into various products. However, the transportation and handling of plastic pellets present challenges, as spills and leaks are common during loading, unloading, and transportation.

To address this issue, containment systems have been developed to capture and contain pellet spills or leaks. These systems include secondary containment systems, spill containment berms, railcar spill containment, and above-ground storage tank systems. Organizations are encouraged to implement tailored plastic pellet containment solutions to effectively manage pellet spills and reduce their environmental impact.

The plastic pelletizing recycling system offers a closed-loop solution by converting plastic scraps into usable clean raw material. This process helps reduce waste and reuse materials, minimizing the environmental footprint of plastic manufacturers. However, the success of these initiatives relies on corporate transparency and effective containment strategies to prevent plastic pellet pollution during manufacturing, transportation, and disposal.

Plastic pellet pollution has been documented since 1972, but there is zero corporate transparency

Plastic pellets, also known as pre-production pellets or nurdles, are the building blocks of nearly all plastic products. They are produced by petrochemical companies and transported to manufacturing facilities where they are melted and shaped into the final product. Plastic pellets escape into the environment at every stage of their lifecycle, from production and transportation to final product manufacturing.

Plastic pellet pollution has been documented since 1972, when a study published in the journal Science found that they were "abundant in the coastal waters of southern New England". Despite this long-standing knowledge, there is a striking lack of corporate transparency surrounding plastic pellet pollution. Companies that produce plastic resins have been challenged to disclose their actions to prevent and remediate spills of pre-production plastic pellets into waterways. While some companies have agreed to implement measures for improvement, others have not, demonstrating a continued lack of transparency and accountability.

Millions of plastic pellets are released from production sites each year, polluting surrounding waterways and the ocean. A 1990 report from the EPA expressed concern over the high concentrations of pellets found in the world's oceans, and pellets continue to be found in harbors and coastlines across the globe. In 2016, Eunomia Research & Consulting estimated that 230,000 metric tons of plastic pellets enter the oceans annually.

The issue of plastic pellet pollution is not limited to the ocean. Pellets are also found on beaches and in the sand, as documented by Jace Tunnell on Mustang Island, Texas. Tunnell found countless tiny plastic pellets, which are intended to be turned into plastic products but instead contribute to the growing problem of plastic waste. With increasing amounts of plastic ending up in landfills and the ocean, the lack of corporate transparency and accountability in addressing plastic pellet pollution is concerning.

Plastic pellets are often found on riverbanks, lake shores, and beaches near facilities that handle them

Plastic pellets, also known as "nurdles", are the raw material used to make plastic products. They are typically less than 5mm in size and are often spilled, leaked, or dumped into the environment during manufacturing and transport. As a result, they are frequently found in waterways, including rivers, lakes, and oceans, and have become a major source of marine microplastic pollution.

Given their small size and lightweight nature, plastic pellets are easily transported by wind and water, accumulating in riverbanks, lake shores, and beaches. Their presence in these natural environments is particularly prominent near facilities that produce, transport, or use plastic pellets, as spillage and leakage during these processes are common. Drainage points and the lowest elevation points near such facilities are likely hotspots for plastic pellet accumulation.

The abundance of plastic pellets in an environment is influenced by several factors, including the number of plastic-related industries in the area and their proximity to waterways. A study of the Great Lakes in North America found a direct correlation between the number of plastic industries and the amount of plastic pellets on the lakeshores, with 86% of the pellets concentrated on just three beaches.

The persistence of plastic pellets in the environment is a global concern. A 1972 study published in the journal Science noted the abundance of plastic pellets in the coastal waters of southern New England. More recently, Eunomia Research & Consulting estimated that 230,000 metric tons of plastic pellets enter the oceans annually. The Plastic Pellet Free Waters Act has been proposed as a federal solution to address plastic pellet pollution in the United States, aiming to prohibit the discharge of plastic pellets into waterways.

Plastic pellets can absorb toxins from water and transfer them to the marine food web and human diets

Plastic pellets, also known as microplastics, are a significant source of pollution in the world's oceans. These pellets are small, measuring less than 5mm in size, and are often mistaken for food by marine organisms, including fish, seabirds, and molluscs. While the United States is a major producer of plastic, the global plastic waste crisis is not solely due to its production but also to the improper disposal and recycling of plastic products.

Once in the ocean, plastic pellets can absorb toxins from the water, including persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and organochlorine pesticides like dichlorodiphenyltrichloroethane (DDT) or hexachlorobenzene (HCB). These toxins have a higher affinity for plastic than water, resulting in concentrations on microplastics that are significantly higher than in the surrounding seawater.

As marine organisms ingest these contaminated pellets, the toxins are transferred to their fatty tissues. This process, known as bioaccumulation, results in a buildup of toxic chemicals in the organisms' bodies. When these contaminated organisms are consumed by predators, the toxins are passed up the marine food chain, leading to increased concentrations of toxins in higher-level predators, including those consumed by humans.

Studies have shown that microplastics found in seafood can contain additives and contaminants, such as PCBs, PAHs, and PBDEs (polybrominated diphenyl ethers). These chemicals can have detrimental effects on both marine life and human health. While the full extent of the impact of microplastics is yet to be determined, their presence in the marine food web and human diets is a growing concern.

To address this issue, it is crucial to reduce plastic waste and improve recycling practices. Additionally, further research is needed to understand the long-term effects of microplastics on the environment and human health, leading to informed policies and strategies to mitigate the impact of plastic pollution on our oceans and ecosystems.
