Plastic foam lasts for thousands of years, threatening wildlife
Plastic foam, or polystyrene, is a significant contributor to plastic pollution, threatening wildlife and human health. Its lightweight composition and buoyancy allow it to travel long distances, eventually reaching the oceans, where it harms marine life. While it resists most chemicals, plastic foam can break down under prolonged exposure to sunlight through a process called photodegradation. However, this process only turns the foam into a powdery substance, and it still does not biodegrade, remaining in the environment for hundreds, if not thousands of years.
The non-biodegradable nature of plastic foam means it persists in the environment, causing long-term harm to wildlife. Animals, such as seabirds, mistake the small pieces of plastic foam for food and feed them to their young. As a result, these creatures fill their stomachs with plastic, leading to starvation or permanent injury. The plastic fragments can cause digestion problems, clog appendages, and accumulate in fatty tissue.
The production, use, and disposal of plastic foam generate a substantial environmental burden. It is a common form of pollution in oceans and other bodies of water, with single-use Styrofoam items ending up in landfills and the natural environment. The manufacturing process involves harsh chemicals and releases large amounts of ozone into the atmosphere, impacting respiratory health and contributing to environmental issues.
The toxicity of plastic foam further exacerbates its threat to wildlife. Polystyrene, a main ingredient in Styrofoam, has been identified as a possible human carcinogen. It can leach into food and drinks served in polystyrene containers, endangering human health. The issue is widespread, with plastic foam comprising 90% of all marine debris, and it continues to flow into our oceans at an alarming rate.
Efforts are being made to address the problem of plastic foam pollution. Organizations like Environment Oregon are working to build public support for banning polystyrene foam takeout containers and cups. Additionally, alternative packaging solutions, such as FishCap, are being encouraged to reduce the production and disposal of plastic foam. Despite these initiatives, plastic foam remains a persistent threat to wildlife, underlining the urgent need for sustainable alternatives and comprehensive solutions to tackle this global issue.

Styrofoam is non-biodegradable and non-recyclable
Styrofoam, also known as polystyrene, is a petroleum-based form of plastic. It is made from styrene monomers, which are derived from fossil fuels. Styrofoam is used to make a variety of products, including cups, coolers, packaging, and insulation foam. While Styrofoam may seem convenient, its environmental impact cannot be overlooked.
Styrofoam is non-biodegradable, meaning it does not break down naturally in the environment. It can take over 500 years for a Styrofoam container to decompose completely, and even then, it will never truly disappear, leaving tiny pieces of plastic behind. This is because Styrofoam does not break down but instead breaks up into smaller and smaller pieces, which can be mistaken for food by animals. These microplastics can enter the natural environment and be ingested by wildlife, leading to health issues and even death.
The production and disposal of Styrofoam also pose significant environmental and health concerns. The manufacturing process releases toxic chemicals, including ozone, into the atmosphere, contributing to respiratory and environmental issues. Styrofoam manufacturers were the fifth-largest producers of toxic waste in 1986, exposing over 90,000 workers to the effects of styrene annually.
Additionally, Styrofoam is non-recyclable. While some chemical recycling facilities convert petroleum-based foam into fuel, they do not create reusable materials. As a result, billions of pounds of Styrofoam end up in landfills and waterways each year, contributing to waste accumulation and environmental pollution.
Due to the harmful nature of Styrofoam, several cities and states have banned or restricted its use. As of June 2024, 11 states and more than 250 U.S. cities and counties have implemented such regulations. Individuals can also play a role in reducing Styrofoam waste by avoiding its use and lobbying for bans or restrictions in their communities.

Polystyrene breaks down into microplastics, which animals eat
Styrofoam and polystyrene are often used interchangeably, but they are not the same thing. Polystyrene is a plastic that is used to make Styrofoam, which is a type of plastic foam. Polystyrene is used in a wide range of products, from foam cups and coolers to EPS foam board and packaging. It is also used in the building industry as insulation.
Polystyrene does not readily break down in the environment. It can take hundreds or even thousands of years to decompose, if it ever does so at all. This is because polystyrene does not break down in the same way that organic materials do. Instead, it breaks up into smaller and smaller pieces over time. This process is known as photodegradation and is triggered by exposure to sunlight. The polystyrene eventually becomes a powdery substance, which is then blown by the wind, ending up in streets and storm drains. At this point, it is difficult to collect, and it can persist in the environment indefinitely.
As polystyrene breaks down, it becomes microplastic. These tiny pieces of plastic are often mistaken for food by animals, who eat them. Seabirds and marine animals are particularly affected, as they ingest the plastic particles that float on or near the surface of the water. The plastic builds up in their digestive systems, causing health issues and eventually starving them. Microplastics have been found in the intestines of birds in the Arctic, and in the digestive systems of mussels.
Microplastics are smaller than 5mm in size, and nanoplastics are a subset of microplastics, smaller than 1 μm (1 micrometer or 1000 nm). These tiny particles can enter the food chain of humans and animals, leading to health hazards for top predators.

Styrofoam production and disposal release harmful chemicals
Styrofoam, or polystyrene, is a major environmental problem. The production and disposal of Styrofoam release harmful chemicals, threatening both human and wildlife health.
The Earth Resource Foundation reports that Styrofoam manufacturers were the fifth-largest producer of toxic waste in 1986. Styrofoam production relies on harsh chemicals, including pentane gas, and releases large amounts of ozone into the atmosphere. This has detrimental effects on the environment and human health, causing respiratory issues.
Styrofoam is also a concern in the waste disposal process. As it is non-biodegradable and non-recyclable, it persists in the environment for hundreds, if not thousands, of years. While photodegradation, or exposure to sunlight, can cause Styrofoam to break down into a powdery substance, this process is slow and ineffective in addressing the vast quantities of Styrofoam waste.
Additionally, Styrofoam's lightweight and buoyant properties contribute to its spread across the globe through waterways. It breaks down into smaller pieces, which animals mistake for food. This leads to plastic accumulation in their stomachs, causing starvation and injury.
The health effects of exposure to styrene, the primary material in Styrofoam, are significant. Acute exposure can cause skin, eye, and respiratory tract irritation, as well as gastrointestinal problems. Chronic exposure affects the nervous system, leading to symptoms like depression, headaches, fatigue, and weakness. It can also have minor impacts on kidney function and blood composition.
To address the issue of Styrofoam's environmental and health impacts, alternative materials, such as recycled paper products, are recommended. These alternatives are biodegradable, non-toxic, and easily recyclable, offering a more sustainable and safe option for both people and the planet.

Some places have banned Styrofoam due to its negative environmental impact
Styrofoam, or polystyrene, takes around 500 years to decompose and is not readily biodegradable. It is harmful to the environment and human health, and its manufacture releases large amounts of ozone into the atmosphere. It is also a contributor to microplastics, which are a form of maritime debris. As a result of these negative impacts, some places have banned Styrofoam.
In the United States, cities such as Baltimore, St. Louis Park, Edina, Roseville, and Saint Paul have banned single-use polystyrene. In Maryland, a state with over 11,000 restaurants, a styrofoam ban will affect multi-location restaurant chains. Hawaii has also effectively banned styrofoam, with every county except Kalawao County enacting polystyrene bans. In addition, 12 U.S. states and two territories have passed legislation to ban polystyrene foam, with Maryland being the first state to do so in 2019.
Outside of the U.S., several countries and territories have also banned styrofoam. This includes Nigeria's states of Lagos, Abia, and Oyo; the Australian Capital Territory, New South Wales, Queensland, and other territories; and the United Arab Emirates, which will ban polystyrene in 2025 and single-use plastic food containers in 2026.
These bans have been driven by a desire to protect the environment and reduce the impact of single-use plastics. Some cities, such as Baltimore, have been influenced by community-driven environmental advocacy groups and youth organizations. Restaurants that violate these bans may face fines of up to $1,000.
