In my series on polystyrene food containers, I’ve explained how it is used, produced, and why it is harmful to human health as well as the environment. I’ve examined why it is not practical to recycle polystyrene even though its producers would have you believe otherwise. In Part 4, we explored supposed alternatives and why they weren’t totally effective. Today, I want to discuss corporate responsibility and how bans on polystyrene can help bring greater change.

The Role of the Food Industry

The fast-food and restaurant industries can play a huge role in ending the use of polystyrene. Many use polystyrene for their hot and cold drink cups and clamshell containers, but they have a choice in what they purchase. Most dine-in restaurants already use reusable dining ware and the ones that don’t could make the choice to switch and install a dishwasher. The initial investment would be higher, but the constant overhead of disposables would disappear and trash costs would go down. For take-out and leftover containers, there are many ways companies can offset the increased costs of non-polystyrene packaging. They could allow customers to bring their own containers and/or they could raise the cost of their products by mere cents. Companies have the opportunity to be part of the solution in order to protect our own habitat.

A few companies have self-imposed bans on polystyrene. McDonald’s phased out polystyrene containers for its sandwiches in 1990 after their containers became a symbol for litter. These containers are so well-known in advertising and consumer culture history that the Smithsonian has those containers in their archives.¹ It stopped using polystyrene for hot beverages in 2012 after being pressured by environmental groups, and they were supposed to end the use of cold beverage cups by 2019. Dunkin’ (formerly known as Dunkin’ Donuts) eliminated polystyrene coffee cups in May 2020. They estimate that this will remove one billion cups from the waste stream annually.

The Role of Manufacturers

The manufacturers of polystyrene have an obvious interest in keeping it in use. But they argue against the environmental and human health problems stemming from it. They also promote recycling as a solution when it is not because of the volume. Corporations have the opportunity to do so much more than they do!

Case Study: Dart Container Corporation

Dart Container Corporation manufactures over 4,000 products including cups, plates, containers, lids, and straws for everyday use in restaurants, hospitals, schools, and homes. Their environmental commitment lists recycling polystyrene as one of their strategies, using what they collect at their plants and other drop-off facilities across the U.S. “We are the award-winning industry leader in creating and promoting recycling opportunities for EPS foam #6.”² They sell it to manufacturers of picture frames, interior molding, pens, rulers, and foam packaging.

But they charge customers to collect polystyrene cups for recycling. They have a program called The Cups Are REcyclable (CARE), that offers Dart customers “an easy and affordable way to recycle foam food containers” for “Dart’s large-volume users, such as hospitals, universities and corporate cafeterias.” This provides educational materials, a collection bin, and a densifier (like a compactor) for a cost of $295 per month. The customer is responsible for the installation and maintenance of the machine, but Dart collects it once per month.³

Dart also has its Recycla-Pak program, a foam cup take-back program offered for sale by Dart distributors. Usually, companies cover the costs of take-back programs, not the customer. These are actually brilliant business models for Dart. They sell the single-use disposable cups, reclaim it at the same customer’s cost, and then resell the recycled products to new customers. Profit all around! But this isn’t the right thing to do and it inhibits recycling because of the cost.

Bans on polystyrene

Many communities across the U.S. have instituted polystyrene bans, but it is a surprisingly controversial issue. There are those who recognize that we need to move away from polystyrene because of human health hazards and to curb pollution. Others think that replacement choices aren’t much better for the environment and that businesses will suffer from the higher cost of the replacements. I’ll explain a few of these bans.

California

California has approximately 121 local municipal ordinances throughout the state banning polystyrene.⁴ Although there is not yet a state-wide ban in California, this shows how many citizens want to stop the use of polystyrene. Food containers are not recycled in California, “although the plastic industry has attempted to implement recycling programs that are simply way too expensive to be implemented in any meaningful way.”⁵ Besides impaired waterways littered with plastic and polystyrene trash, a 2004 report indicated that it was costing about $30 million per year to dispose of polystyrene materials.

In addition, in order to clear up confusion about customers using their own containers, the State of California passed Assembly Bill 619 in 2019. This new law now clearly allows the use of reusable food and beverage containers at restaurants and events in the state.⁶ I would love to see other states follow their lead so that this was allowed everywhere.

Maryland

Maryland was one of the first states to pass a polystyrene ban. “Environmentalists say the new law will have long-term benefits, removing a material made with fossil fuels, which contribute to climate change, and that clogs landfills, pollutes the Chesapeake Bay and other waterways and ultimately harms wildlife, people and the planet,” according to an article in the Baltimore Sun. But those against it say “alternatives to foam don’t always live up to their promises — plastic containers don’t get washed out and recycled or reused, and compostable ones aren’t always compostable without special equipment. Instead, they say, they end up in the same waste stream as the foam they replaced.”⁷

Maryland has not fully implemented the ban yet, as COVID-19 delayed the deadline for schools and restaurants to stop using polystyrene. Trash collection rose 22% in Baltimore during the pandemic, largely due to take-out packaging. It began October 1, 2020 and it will be exciting to see the long-term results.

“If researchers find the law helps improve Maryland’s waterways, that could help guide future policy around the world and “turn off the faucet” of supplying polystyrene into the water.”⁸

Other States

The call to reduce the use of polystyrene has been heard in other places as well. Maine passed a ban on polystyrene food and drink containers in supermarkets and restaurants which will go into effect in 2021. New Jersey has pursued a ban on single-use paper and plastic bags at supermarkets that will also limit the use of polystyrene takeout boxes and plastic straws. As of this writing, it is awaiting the Governor’s signature. These examples show that enough people in those states were concerned about the negative environmental impacts of polystyrene. They recognize that the best solution is to stop using it!

Solution

While there are many alternatives, the best solution will always be to stop using single-use disposable products. It is my hope that polystyrene bans become the norm. Kate Breimann, state director of Environment Maryland, urges us to consider the larger issue of moving away “from the culture single-use” disposable items. She said implementing previous measures to protect the environment once loomed difficult as well, but have since paid off. “We think about when we had leaded gas and leaded paint, and people said, ‘It’s going to be hard for the industry,'” she said. “But now we have a healthier world.”⁹ This is absolutely true, and we all benefit from a healthier environment.

Styrofoam and Polystyrene Containers are Poisoning Your Food, Part 3

In Part 1 and Part 2 of this series, I told you about polystyrene (Styrofoam) food containers, how and what it they are made with, and how polystyrene is harmful and toxic to human health. Today I’ll explain its poor recyclability and its environmental impact.

“The irrefutable evidence and research has been mounting over decades from various federal agencies, city staff reports, state staff reports, environmental clubs, and nonprofits,” pertaining to the negative effects of Expanded Polystyrene (EPS). -Jeff Lewis, environmentalist writer¹

Recyclability

In practice, polystyrene food packaging is not recycled. Despite misconceptions, most municipalities do not accept it for recycling, even with the #6 recycling symbol. If it is collected, it often goes to the landfill instead of a recycling facility. Polystyrene is often contaminated with food residue which makes recycling impractical. Additionally, most establishments that use polystyrene food packaging do not provide separate recycling bins, so customers have no choice but to throw them in the regular trash. Nothing is recycled when it is thrown in the trash.

Even when you do find a place that accepts polystyrene, there’s no guarantee that the meat trays and egg cartons that you wash, save, and cart back to the supermarket actually get recycled, if you’ll recall from Part 6 of my Packaging Series. Often, those collection sites are simply to draw you into the store and keep local recycling streams free from those materials.

“Styrofoam, despite the #6 plastic composition and the misleading recycling symbol it often carries, cannot be recycled easily or cost-effectively – less than 1% of Styrofoam is recycled in the USA.” -Green Dining Alliance of St. Louis

Cheaper to Produce New Polystyrene

Unfortunately, it is also easier and cheaper to produce new polystyrene than it is to collect, sort, and clean it for the recycling process. Thus, the market for recycled polystyrene is small and unlikely to grow. Companies such as BASF and Dart Container Corporation would have you believe otherwise. Both advocate for polystyrene recycling because they are producers of it as well. Many of the companies that do recycle polystyrene don’t accept food containers, they only accept polystyrene shipping materials. There are a few companies that do recycle used polystyrene food containers and have ways to clean them. But because food contamination makes food containers very costly to sort, clean, and recycle, those companies are rare.

New York City’s Department of Sanitation studied recycling polystyrene food containers and determined that recycling them is not economically feasible. “The report found that the majority of Styrofoam collected for recycling ended up in landfill anyway—but at a higher economic cost and carbon footprint compared to being directly landfilled.” This includes the cost of collection, recycling separation and contamination, and ultimately hauling it a second time to the landfill.² The conclusion, as always, is to stop relying on recycling and focus on ending the use of single-use disposable items.

“The reason for the decline in price is that crude oil prices are so low that it is cheaper for companies to produce new Styrofoam products than to clean and reuse postconsumer products. This economic reality discourages other companies from getting into the market of recycling the polystyrene.” -Real Cost of Styrofoam³

The Volume of Polystyrene is Overwhelming

The sheer volume of discarded polystyrene is a problem as well. The world produces about 14 million tons of polystyrene annually. As with any type of plastic, we cannot recycle away the problem of single-use disposable items. We must stop it at the source; refusing to use them whenever possible.

“25 billion Styrofoam coffee cups are used for just a few minutes and thrown away every year.” -Green Dining Alliance of St. Louis

Environmental Impacts

Since polystyrene is not recyclable, most of it goes to landfills and some inevitably makes its way into the environment. According to the Environmental Protection Agency (EPA), Styrofoam production is the fifth largest creator of toxic waste in the United States. Polystyrene products break down into smaller and smaller pieces and eventually become microplastics. Birds and marine life ingest small pieces because they mistake the pieces for food. Additionally, after the ingested polystyrene kills an animal, it can go on to kill again after that animal decomposes and the pieces reenter the environment.

“80% of Styrofoam ends up in landfills, and much of the remaining 20% in waterways.” -Green Dining Alliance of St. Louis

Polystyrene does not biodegrade, even the alleged biodegradable and compostable polystyrene, as I wrote about in Part 2 of my Packaging Series. Again, most take-out packaging is thrown away. Polystyrene foam litter is common as it is lightweight and breaks apart easily, making smaller pieces that become windswept. The Clean Water Action organization noted important facts about polystyrene’s environmental harm:⁴

- - Expanded polystyrene (EPS) products and their associated chemicals (such as styrenes) are widespread in the marine environment.
  - Polystyrene is in the digestive tracts of marine invertebrate and vertebrate wildlife.
  - Polystyrene is one of the most common types of debris on shorelines and beaches worldwide.

“Why is such a toxic material in use? Polystyrene is cheaper than some alternatives. However, the environmental expense of polystyrene far exceeds the cost restaurants and grocery stores are currently paying to provide them.” -Massachuesetts Sierra Club⁵

Solution

After considering the costs to human health, wildlife, and the environment, the solution is to end the use of polystyrene food packaging. Many reports have a similar conclusion and call for banning polystyrene or finding alternatives (see Additional Resources below). We must call for businesses to stop using these products and for local governments to ban their use. Moreover, we need to greatly reduce the amounts of all single-use disposable products we use. In my next article, I’ll explore alternatives to polystyrene food containers, the role of companies in their use of it, and municipal bans on polystyrene.

Styrofoam and Polystyrene Containers are Poisoning Your Food, Part 2

Last updated on May 2, 2023.

In Part 1 of this series, I introduced polystyrene, which we commonly refer to as Styrofoam, food packaging. This type of plastic is terrible for the environment and human health. Today, we’ll look at the toxicity of polystyrene in depth.

After watching friends and coworkers repeatedly reheat their take-out and leftovers in polystyrene, I decided to write an article about it. I had known polystyrene was potentially toxic for a long time, but I had no idea just how toxic it is.

Chemicals Leach from Containers into Food

Polystyrene leaches styrene and benzene, chemicals that have known toxic properties, into food. In testing, one scientific journal independently tested and found that polystyrene leaches more toxins when in contact with high-temperature contents and into foods with higher fat content.¹ That means that if you buy hot food, fatty food, soup, or coffee and it is packaged in polystyrene, some of the chemicals from the container leach into your food. Over time, these chemicals can cause severe health problems.

“Styrene is likely to leach when it comes in contact with fatty foods, hot beverages, and especially alcohol. When thinking about the kinds of foods that typically end up in Styrofoam containers (fatty foods) and cups (hot coffee), it seems as though the exact kinds of items Styrofoam contains are exactly the kind of items it should never touch.” -The Green Dining Alliance²

I recently went to a BBQ restaurant in Dayton, TN. They serve most of their food in polystyrene containers. My fried okra melted the polystyrene and those chemicals certainly leached into my food. I didn’t eat the okra, I dumped it out so that I could photograph the container. I likely will never dine at that place again. It really concerns me that people eat food out of these types of containers every day! Photo by Marie Cullis.

Known Toxicity

When I searched “polystyrene human health” I got more than 13 million results. After reading many articles, I realized that all organizations and even the U.S. government, including the Environmental Protection Agency (EPA), know that polystyrene is harmful to human health as well as land and marine environments. Furthermore, the Food and Drug Administration (FDA) permits the migration of styrene from packaging into food!

Study after study shows that chemicals from polystyrene leach into foods and beverages, especially with higher temperatures and food with higher fat content. And study after study shows that styrene is dangerous to human health. In fact, most agencies caution against the use of polystyrene because of the known health hazards, including these:

- - - The Environmental Protection Agency (EPA)
    - The World Health Organization (WHO)
    - The International Agency for Research on Cancer
    - National Institute for Environmental Health Sciences
    - U.S. Department of Health and Human Services (DHHS)
    - National Research Council (NRC)
    - Occupational Safety and Health Administration (OSHA)
    - National Institute for Occupational Safety and Health
    - The Agency for Toxic Substances & Disease Registry (ATSDR), Center for Disease Control and Prevention (CDC)

A Known Carcinogen

Styrene exposure increases the risk of leukemia and lymphoma and is a neurotoxin. This alone is enough reason to avoid polystyrene containers. In 2018, the World Health Organization (WHO) reclassified styrene as a probable carcinogen.³ While the EPA does not classify it as a carcinogen, it noted that animal cancer studies provided evidence for carcinogenicity.⁴ Several of the organizations mentioned above, including the International Agency for Research on Cancer and the Department of Health and Human Services, consider it to be carcinogenic.

Hormone Disruption

There are countless studies that show certain types of plastics contain known hormone disruptors. Those chemicals often mimic estrogen and they seep into food and beverages (including breastmilk). In 2014, Environmental Health tested 11 samples of polystyrene and consistently found estrogen seepage after exposure to intense steam or ultraviolet rays.⁵ Since polystyrene is a type of plastic, this is just one more reason to avoid polystyrene containers.

It is terrifying that many schools use foam trays for cafeteria food. Hormone disruption in young children prevents them from developing normally, can affect their ability to reproduce as adults, and can set them up to be prone to other diseases.

Other Health Hazards

Styrene exposure can come from other sources, such as photocopier toner, automobile exhaust, and plastics manufacturing. Exposure can cause irritation of the skin, eyes, mucous membranes, the upper respiratory tract, and gastrointestinal irritation. Chronic exposure can cause neurological problems such as depression, headaches, fatigue, weakness, hearing loss, and disrupted kidney function.⁶

Additional Unknown Chemicals

There are many chemicals and ingredients that are not tested for and not regulated by the EPA and FDA. While this may seem surprising, the standard operating procedure in the United States is to allow a chemical to be used until a known hazard is not only discovered, but proven. Essentially, chemicals are innocent until proven guilty.

Exposure through Manufacturing

Anyone who lives near or works in polystyrene manufacturing sites is at risk of even greater health problems due to respiratory exposure. The Clean Water Action organization noted that “occupational exposure to Styrene increases [the] risk of lymphoma, leukemia, lung tumors, pancreatic cancer, urinary bladder cancer, prostate cancer, and colorectal cancer. High rates of neurotoxicological effects have been reported in workers,” as well as decreased sperm counts.⁷ These plants also emit a toxic and volatile gas called pentane, often used as a blowing agent in the production of polystyrene.

“Over fifty chemical byproducts are released during the manufacturing of polystyrene, contaminating the air, water and communities that live near these facilities.” –Children’s Environmental Health Network⁸

What You Can Do

Polystyrene is toxic to human health. When ordering take-out, ask the restaurant if they use “Styrofoam” or polystyrene containers. If they do, you can ask if they have an alternative type of container or you can decide to order from somewhere else. When bringing leftovers home from a restaurant, keep a glass or metal container in your car specifically for such occasions. Bring your own reusable coffee mug to coffee shops. As I mentioned at the beginning of my article, try to avoid eating food in polystyrene, and definitely stop reheating your food in polystyrene containers in the microwave.

Last, polystyrene is the most common type of #6 plastic and is largely not recyclable because of food contamination. In Part 3, I will cover the problems with recycling and the environmental damage polystyrene causes. Thank you for reading, and please share and subscribe!

Styrofoam and Polystyrene Containers are Poisoning Your Food, Part 1

Last updated June 20, 2021.

Take-out has definitely increased in popularity since the onset of COVID-19 and often take-out and leftovers are transported and served in what we colloquially refer to as Styrofoam containers. These containers present several problems because they largely cannot be recycled or composted. These items clutter up landfills, litter rivers, and pollute oceans. They are extremely dangerous to marine life because the containers break down into small pieces that many species ingest. Worst of all, these containers leach toxins into our food, and those toxins are poisonous to humans.

This is the first of a five-part series to explain the dangers of putting food into said containers. I want to acknowledge that I am neither a physician nor a scientist. I am, however, a concerned environmentalist, mother, and friend, and as such I must inform you that I feel it is imperative to stop eating and reheating food in Styrofoam/polystyrene containers immediately.

Styrofoam vs. Polystyrene

Foam take-out containers are actually made of polystyrene, which is how I’ll refer to them in this post. Though it has become a genericization, Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS), commonly called “Blue Board” and used in building materials and insulation. This material is light blue in color and is owned and manufactured by The Dow Chemical Company. The kind used for take-out and food packaging is actually Expanded Polystyrene, or EPS. Both types have insulating and cushioning properties.

“Polystyrene is the name for a whole family of plastics … but the foam forms have [a] disproportional environmental impact.” -Joseph A. Davis, Society of Environmental Journalists

What is Polystyrene?

Polystyrene is a chemically produced plastic that can be a hard or foam plastic. The foam is created by expanding the styrene (plastic), a petroleum by-product, which is accomplished by blowing various gases into it. Polystyrene is made from ethylene and benzene, both hydrocarbons derived from petroleum and natural gas, also known as petrochemicals. So those fast-food containers are made from fossils fuels and mixed with chemicals. That doesn’t sound too appetizing, does it?

The American Chemistry Council (ACC), promoters of all plastic despite the human health and environmental problems it causes, infers that polystyrene is natural when it is far from it: “Polystyrene is made by stringing together, or polymerizing, styrene, a building-block chemical used in the manufacture of many products. Styrene also occurs naturally in foods such as strawberries, cinnamon, coffee and beef.”¹ They are referring to the minuscule amounts in those natural items, which are not mixed with additional additives and chemicals that are potentially dangerous. I find it appalling that the ACC makes such a comparison.

Added Chemicals

Many sources indicate that polystyrene is made up of mostly air, but that’s not completely accurate. The plastic is expanded into foam by creating air pockets between the polymers, but a gas or a chemical is used in expanding it. The industry formerly used chlorofluorocarbons (CFCs) as a blowing agent, and as you may know, CFCs deplete the planet’s protective ozone layer. Most CFCs have been removed worldwide following bans in the late 1980s.²

Today, there are two principal methods of production for polystyrene in the United States, according to the CDC’s Agency for Toxic Substances and Disease Registry. The primary method uses ethylbenzene; the second is created through a series of chemical reactions using ethylbenzene, propylene, propylene oxide, and α-methyl phenyl carbinol.³

Use of Polystyrene Containers

Polystyrene is used for packaging materials, insulation, fiberglass, automobile parts, plastic pipes, carpet backing, boat hulls, and food packaging and containers. There are two types of EPS food containers. The rigid form is used for clear food containers, plates, bowls, beverage cups and lids, utensils, and straws. The foam form is used to make plates, insulated beverage cups, soup bowls, ice cream cups, clamshell food containers, meat trays, and cafeteria trays. These containers are everywhere: restaurants, fast-food restaurants, cafeterias, buffets, coffee shops, ice cream shops, movie theaters, grocery stores, supermarkets, etc.

Inexpensive but Harmful

This material is inexpensive to manufacture. It is also cheap to ship because polystyrene is so light, but it also makes it easy for the pieces to take to flight, littering our roads, rivers, and ocean. The ACC really promotes the use of material despite environmental and human health hazards: “Polystyrene foodservice packaging typically insulates better, keeps food fresher longer and costs less than alternatives.”⁴ But the true cost is devastating when considering the pollution, human health effects, and harm to wildlife.

“When considering the cleanup costs, carbon emissions, environmental costs, and potential health effects, the hidden cost of Styrofoam comes out to $7 billion, annually.” -Green Dining Alliance of St. Louis

Looking Forward

The world produces more than 14 million US tons of polystyrene each year according to earthday.org and the Green Dining Alliance. Most of that ends up in the trash or worse, our land, rivers, and ocean. Polystyrene is the most common type of #6 plastic and is largely not recyclable because of food contamination. I will explore these topics more in Part 3 of this series. For now, please know this, these containers leach harmful chemicals into your food, especially when heated. The best thing you can do is not to use them.

When ordering take-out, you can always ask the restaurant if they use “Styrofoam” or polystyrene containers. If they do, you can either ask if they have an alternative or decide to order from somewhere else. When bringing leftovers home from a restaurant, keep a glass or metal container in your car specifically for such occasions. It’s also a good idea to bring your own reusable coffee mug to coffee shops. As I mentioned at the beginning of my post, please try to avoid eating food in polystyrene, and definitely stop reheating your food in polystyrene containers in the microwave. Polystyrene is toxic to human health. I will cover this in more detail in my next post, Part 2.
