The Chemicals in Plastic and Why it Matters, Part 1

Plastics are made from chemicals and petroleum.

I have found that most people don’t know that, or don’t care to know. Many plastics are full of potentially toxic chemical concoctions, and knowing what makes up plastics is key to understanding how dangerous those chemicals are. Once you know that, it’s hard to understand why would the FDA, EPA, and other government regulatory agencies allow them to be used in, well…everything.

The short answer is, they just don’t regulate that many chemicals.

But plastics are all around us in everyday life, and thus we are regularly exposed to these chemicals. This is one reason I’m anti-plastic, at least in the way we overuse and overconsume it in daily life.

How Plastic is Made

“Most plastic is derived from oil drilling and/or fracking.” -Jennie Romer, sustainability expert and attorney¹

Plastics are derived from fossil fuels, such as crude oil and natural gas. It is then processed at a refinery into ethane and propane. Next, they go to what are called cracker facilities that “crack” or break down these molecules. They turn ethane into ethylene, which is a building block of most common plastics. Propane becomes propylene. They are mixed with a catalyst, or chemical additive, that links the molecules together and forms polymers. Polymers are long, repeating chains of molecules that are chemically linked, or bonded, together. Harken back to chemistry class and this process is called polymerization.

But “polymers alone rarely have the physical qualities to be of practical value, so most plastics contain a multitude of chemical additives to facilitate the manufacturing process or produce a particular desirable property, such as flexibility, toughness, color or resistance to UV light.”² This process forms different resins, or types of plastics, and are generally categorized by Resin Codes (those little numbers on plastics with the recycling symbol around it).

Plastic is Toxic

These chemical additives are usually what is most harmful to our health and the environment, as they leach over time and under certain conditions such as heat or UV exposure. Additives include dyes, “fragrances” or phthalates, plasticizers such as bisphenol A (BPA), fillers, fluffers, hardeners, stabilizers, lubricants, fire retardants, blowing agents, antistatic chemicals, and even fungicides and antibacterial agents. “Imagine that, plastics eerily designed to repel insects and bacteria, just like genetically modified cotton or corn!” wrote Chantal Plamondon and Jay Sinha, founders of Life Without Plastic.³

Many chemicals are not even regulated. For example, the FDA banned BPA from infant formula packaging, baby bottles, and sippy cups in 2013 because of its toxic leaching. But, there is a whole family of other bisphenols and most of those are still in active and legal use.

Plastic is often intended for single use only because the toxins leach out over time into your water, food, or product. As Chantal Plamondon and Jay Sinha noted: “We would wash and reuse single-use water bottles over and over, thinking we were being super eco-aware by preventing them from being recycled after a single use or heading straight into the trash and, ultimately, a landfill. We didn’t realize each use and wash was breaking down the cheap, unstable plastic more and more, and increasing the potential for chemicals and microscopic bits of plastic to leach into our drinks.”⁴ I used to reuse my plastic water bottles too – and I stored mine in the car, where the plastics were exposed to intense heat and sunlight, both factors that accelerate plastic chemical leaching.

Plastic Marketing

Facing changing public opinion about the harmfulness of plastic in the 1980s, the plastics industry “launched a $50M-a-year ad campaign to improve plastic’s image. Part of the message was ‘recycling is the answer.’ Within the plastics industry, however, it was later revealed that even then there was serious doubt that widespread plastic recycling could ever be made economically viable.”⁵ They knew then, and they certainly know now, that we cannot recycle all of the plastic. Despite the pollution and toxicity, the plastics industry continues to push, market, and produce excessive plastic products and packaging.

“If the public thinks that recycling is working, then they’re not going to be as concerned about the environment.” -Larry Thomas, former head of the Society of the Plastics Industry, now called the Plastics Industry Association⁶

There are many advocates for plastic production, including the chemical, trade, and petroleum organizations. The global plastics industry is worth between $500 and $800 billion dollars. The plastics industry is not going away while there is that much money at stake.

The American Chemistry Council (ACC) is one of the biggest supporters of plastics, and they spend millions each year contributing to political parties in order to fight legislation that would regulate plastic production. Other organizations protective of plastics include (but are not limited to) the Plastics Industry Association, the American Chemical Society, the Manufacturers Association for Plastic Processors, the International Association of Plastics Distribution, the Vinyl Institute, the American Fuel & Petrochemical Manufacturers, and the Society Of Plastics Engineers.

The Overproduction of Plastic

“Many of these products, such as plastic bags and food wrappers, have a lifespan of mere minutes to hours, yet they may persist in the environment for hundreds of years.”⁸

There are a few plastics that have an important place on our planet and in our lives, but most do not. Single-use disposable plastics are the major culprits of our plastic pollution problem. The companies we purchase products from are now producing it at such a high rate that we cannot recycle the problem away. Plastic production increased exponentially, from 2.3 million tons in 1950 to 448 million tons by 2015, and it is expected to double by 2050.⁹ “Plastic is too microscopically dispersed around the world to try and clean it all up at this point…Prevention and avoidance should be engraved in our minds,” wrote Chantal Plamondon and Jay Sinha in Life Without Plastic.¹⁰ Companies and manufacturers must stop producing so much of it!

“Half of all plastics ever manufactured have been made in the last 15 years.”¹¹

Watch this short film about plastic from The Story of Stuff Project:

“We have polluted the planet with indestructible plastic to such a degree that plastic may serve as a fossil marker in our strata to indicate a new era – the way dinosaurs indicate the Mesozoic one – until Big Oil digs the last of those reptiles up to produce more Coke bottles.” -Anne-Marie Bonneau, author of The Zero-Waste Chef¹²

What To Do

Whatever it takes to slow or stop the neverending barrage of chemical toxicity and plastic pollution being perpetrated on our planet by profit-driven entities, you can start at home and start small. You can avoid and refuse single-use plastic, changing your habits surrounding it one step at a time. I offer many ways to eliminate plastic on my site in my articles such as “11 Ways To Go Plastic-Free With Food,” and under Resources, where there are lists of books, films, and other websites that offer good information.

You have to eliminate plastics in your life in small manageable chunks, because there’s just so much of it. As the founders of Life Without Plastic wrote, “As excited as you may be to embark on this journey, be careful about fully embracing plastic-free living cold turkey, and trying to do it all at once. Once you start noticing the plastic around you, it could overwhelm and discourage you quickly…Take it one step at a time. This is all about changing habits, and that takes time, effort and patience.”¹³ This will protect you and your family from potentially toxic products entering your body and harming your health.

Contact companies whose products you consume and ask them to switch to responsible packaging. Switch the products you use with items that don’t have plastic. Support legislation like the Break Free From Plastic Pollution Act.¹⁴ Getting manufacturers and companies to stop the overproduction of plastics will be key, and to do so we will have to force them through purchase power and legislation.

“We are surrounded by the toxic polluting conundrum that versatile convenient plastic has become. But . . . there are lots of ways to avoid plastics in everyday life – wherever you are, whatever you do. All it takes is a little awareness and initiative. Educated actions, we like to call it.” –Chantal Plamondon and Jay Sinha, Life Without Plastic¹⁵

You Don’t Need to Spend Money on Trash Bags

I haven’t bought trash bags in more than four years.

How on Earth is that possible? I can’t wait to tell you!

Paying for trash

We are intentionally paying for something we are going to throw away.

We all pay for garbage removal in some form, whether through municipal or property taxes or through a waste management service. On top of that, the traditionally accepted way of containing this trash is single-use plastic trash bags. We pay for new plastic bags, made from fossil fuels, to deposit and remove waste from our homes.

Every time consumers purchase plastic, we are supporting the plastics industry and fueling the effort to harvest more fossil fuels. Then we take those bags we paid for and put them in the ground. We are paying to throw stuff away.

“The first plastic garbage bag was produced in 1950. Globally, these bags collect 7.4 million tons of waste each day.”¹

I’ve saved quite a bit of money by not buying trash bags. Trash bags range from $4 per box up to $12 per box depending on size, strength, flexibility, and even scent. Advertisers want you to believe that the most expensive trash bags will keep your home clean and sanitary. This is not a new trend, but one that has been accelerated by companies such as Glad Products (owned by Clorox) who conducted surveys and discovered that many Americans believe any bad smell means their home is dirty (or rather, fear that other people will think they’re house is dirty). Worse, scented trash bags likely contain phthalates (commonly referred to as “fragrances”) which are usually endocrine and hormone disruptors that can cause serious health problems over time. These scents may mask the odor of your garbage, but at what cost to your health?

Another marketing trend to be aware of is “biodegradable” or bioplastic trash bags. Don’t be fooled. Nothing, including these bags, breaks down in a landfill. They require an industrial composting facility to biodegrade. “There’s also no telling if harmful additives or chemicals were added during the manufacturing process, and not all bags labeled biodegradable or compostable will actually break down in a compost facility.”² Recycled plastic trash bags are better than new or ‘virgin’ plastic bags, but I still do not buy these for my home.

“Landfills are not meant to encourage decomposition. They are dry and anaerobic spaces that essentially ‘mummify’ anything contained in them, including plastic.”³

But now you can stop buying them too.

Necessity

Three years ago, it occurred to me that I was wasting money buying bags just to put in a landfill. Then I read a blog article on myplasticfreelife.com and decided that there really is no need for store-bought plastic garbage bags. “Since we make almost zero trash, and the trash we do make is dry, we don’t have any need for bags to collect it,” the author wrote.[efn_note]Article, “Collecting Garbage Without Plastic Trash Bags?” myplasticfreelife.com, February 15, 2010.[/efn_note] I found that once I eliminated wet garbage, I no longer needed plastic garbage bags.

What is wet garbage?

This mostly refers to food scraps and food waste. If you are able to compost through a municipal service like the ones they have in California, please do so. However, many cities and states do not offer this service as part of their waste management plan, including where we live. My family decided to start our own compost bin, which you can read about here. If you start composting, you will not have wet trash and thus will not need a plastic liner. Best of all, except for the initial cost of implementing a compost bin, composting is free! If you are paying for waste removal directly, you can reduce the amount of trash and frequency of pick-ups (thus cost savings) simply by composting.

About 34% of our waste is food scraps, yard trimmings, and other biological waste.

Waste reduction

We’ve noticed that many neighbors fill their 96-gallon city-issued garbage bin almost every week. We’ve only filled ours once, and that was when we had a major bathroom remodel in our home. But every city household is allotted a 96-gallon garbage bin that is picked up weekly. I haven’t done the exact math, but I believe that that is between 8 and 12 million gallons of garbage per week that our just our city is potentially landfilling.

This must stop. Our globe cannot sustain this level of trash.

My family reduced our waste by buying food and other items with as little packaging as possible. We eliminated single-use disposable items and recycled what we could. Striving to be plastic-free and live a minimalist lifestyle reduced our overall trash. With these efforts, combined with composting, our garbage volume went down to about one bag of trash per month!

One bag of trash per month is far from our zero-waste goal, but it’s much less compared to most households. And Chattanooga is not zero-waste friendly.

Is Trash-Bag Free Possible?

It depends on how much trash you create, where you live, and how trash is transported. Some municipalities require garbage to be bagged. I wanted to stop using trash bags completely. But what I discovered with our city waste haulers is that unbagged garbage tends to either not make it into the trucks and falls on the ground in the neighborhood, or it blows out of the truck while they are driving down the road. In fact, I saw it happening so often that I tried to report the incidents to the city. But I could not obtain enough information about specific trucks while driving to provide good reporting, so nothing came of that. Pay attention to the waste hauling trucks in your area, or call your local municipality and find out if they have measures in place to help prevent these problems.

Trash Bag Alternatives

I let our house run out of garbage bags three years ago and haven’t bought any since. However, since we have to use some kind of trash bag, just to keep our trash contained after it is picked up by the city, we use anything that resembles a garbage bag and staple them closed when it is full to prevent spillage. You can use anything! The most common of these includes:

- - Brown paper bags from the grocery store
  - Empty dog food bags
  - Large shopping bags that show up (even though we always use our own cloth bags at the store, these still manage to make their way into my home from shipping, other people, etc.)
  - Mulch and gravel bags (this is hard to buy in bulk where we live unless you own a truck)
  - Foil insulation bags (these are from Amazon/Whole Foods – during COVID-19 we had to get grocery store delivery for a while, and this was how they delivered our cold items. We have a couple of dozen of these now and they are not recyclable.)
  - Make your own DIY trash bags out of shipping envelopes

I also loved finding a use for these items. It felt wrong to buy a trash bag to throw away more bags or paying to bag the bags.

Looking Forward

I would like to further reduce my waste through less and better packaging, improved zero waste capabilities, striving for plastic-free living, and minimalism. Ideally, someday, I won’t have so many shipping envelopes around. It would be better if I could purchase items in person and locally, which will take not only getting past the pandemic but businesses increasing package-free/plastic-free/zero-waste options in our area as well.

So free yourself from this practice of buying new plastic to almost directly put in the ground. You can stop paying for trash bags today, and use whatever bags come into your home. Thank you for reading, and please subscribe!

Book Review: “You Wouldn’t Want to Live Without Plastic!”

I love books and love sharing books with my son. However, once in a while, we come across a book that offers poor or inaccurate information. This book is one of those. I like to focus on positive reviews, but I feel reviewing this book is important for people to be aware of because it has a lot of misleading information. This is only my opinion.

We know that while there are a few really great uses for plastic in the world, such as plastic heart valves, most plastics are wasteful, full of toxins, and are not reusable. Unfortunately, we humans have gone overboard on plastic consumption and waste, which is why we have to fight so hard to reverse the damage now.

The Good

The book provides a concise history of plastic development and manufacturing, which is helpful for the recommended age range of 8-12 years. The story explains that post-1950s was “the beginning of our ‘throwaway’ lifestyle. Instead of repairing something, we throw it away and buy something new to replace it.” Here is a missed opportunity to express that that is the wrong thing to do environmentally.

The story mentions that certain types of plastics can be used to make strong materials for safety. These include clothing to protect firefighters, race car drivers, and helmets for sports and biking/motorcycling. Some plastic is even made fireproof. As I said, plastics do have their place, sometimes.

The book indicates that there are problems with plastic, but not until toward the end of the story. It mentions that animals ingest plastics and that plastics are polluting the ocean. It offers solutions such as recycling and incineration. But as we know, only about 9% of plastics are actually recycled. Incineration pollutes the air with toxic chemicals released from plastics during burning.

Some extra facts were listed at the end of the book. One of them, which I feel should have been at the beginning or in the part about the future, was: “Plastic takes so long to break down that nearly every piece of plastic ever made still exists today.” That’s exactly why we have problems now.

The Bad

Since we have such a problem pollution problem now, authors have the opportunity to teach children to look for alternatives in the future. Unfortunately, the majority of the book promotes plastic as a good resource that we NEED. It explains the different methods of plastic production, and how plastic begins as nurdles, although they didn’t use that term. It did not mention the various chemical compositions of plastic, or that they can be toxic to human health.

For example, the book mentions twice that plastic is better for toys because plastic is safer and more durable. Perhaps more durable than glass or porcelain in the hands of a child, but not more durable than metal or wood. And safer is not always true. If you compare it to toys made from lead, yes, because lead is highly poisonous. But we also know that chemicals like phthalates and BPA are found in many plastic toys and infant items. There are other chemicals in plastics that we don’t know the long-term effects of yet.

Another example indicates that synthetic clothing is better because those will not shrink like clothes made from natural fibers. True that they may not shrink, but we know that microfibers from washing synthetic clothing are in our rivers, lakes, and oceans. Clothing made from natural fibers is best.

Under a subheading entitled Looking Into the Future: “Most plastics are made from chemicals that come from oil, but oil causes pollution, and it will run out one day. Don’t worry, you won’t have to do without plastic. Future plastics will probably be made from natural materials…” called bioplastics.

If it were that easy, why haven’t we been doing that all along?

The Awful

There were a few parts in this book that I think contain extremely misleading information. One example is that the book suggests that plastic home items, such as doors and windows, are better because they last longer than wood. But sometimes those products contain chemicals banned in the State of California, known as Proposition 65. That legislation requires labeling of such materials now, thankfully, as they have been tied to a number of diseases and cancer.

Here is another example:

If it weren’t for plastic, you’d have to work a lot harder at home…Modern nonstick saucepans are easier to clean than old iron or enamel pans.

Non-stick pans, particularly Teflon, contained dangerous toxins for decades. Those toxins have been linked to thyroid disorders, chronic kidney disease, liver disease, birth defects, and testicular cancer. Only in recent years has that chemical been removed from Teflon, and I’m not convinced that the replacement chemicals in relation to human health have been studied thoroughly. Further, who knows what’s in the non-brand versions of Teflon cookware.

My last example is when the book mentions that credit cards, first issued in the 1950s, are made of plastic. “These plastic cards make it easier for people to buy new products from stores.” Oh my, that is Just. So. Wrong. No, credit cards delude people into buying stuff they don’t need and going into debt. Dave Ramsey and like-minded financial experts would probably drop their jaws if they saw that sentence. I don’t like being so critical, but talk about sending the wrong message to our children!

The right messages

Plastic is not evil, but the way we use it and waste it is. If we want to protect our children, our health, and our environment, we’ve got great changes ahead of us to make. So let’s stick to books that teach our children the right messages about health and the environment.

I hope this was helpful. Thank you for reading!

Death of a Plastic Shower Curtain, Part 1

Last updated on February 13, 2022.

Recently, my plastic shower curtain bit the dust – it’s beyond repair now. My family moved into our house about 3 years ago, and at the time, although I’d always been a huge recycler and I was environmentally conscious, I didn’t really KNOW about the scale of the plastic problem yet. So this was the plastic shower curtain liner we purchased – a standard PEVA (polyethylene vinyl acetate) liner that is found in many homes because of its low cost and effectiveness. It had that new plastic smell that we have all come to associate with new and clean. This was before I knew that that smell was actually the off-gassing of toxins, such as phthalates, toluene, ethylbenzene, phenol, methyl isobutyl ketone, xylene, acetophenone, and cumene. Yuck, what are all of those things? At the time, I didn’t understand what those chemicals were, but I found that research indicated that they are harmful to human health.

“That smell, the one that comes pouring out of the package when you open it, is a plume of toxic gases that have built up while the item was sitting on the shelf.”-Michael SanClements, author of Plastic Purge¹

Mold and repairs

This plastic shower curtain grew mildew and mold consistently! Gross. We have an old house and there is no ventilation in the bathroom, so that’s part of the problem. Over the years, I cleaned it with bleach, Comet, vinegar, Borax, and laundry detergents. All of those worked to clean the curtain temporarily. I’ve even put the whole thing in the washing machine on a casual cycle. But the mildew/mold always came back.

Plastic shower curtains split and break too, and we repaired it over and over again (Beth Terry at myplasticfreelife.com always writes that repairing something as much as possible to extend the life of an item is a great way to reduce waste). The shower curtain had new hole punches, plastic tape, and even staples from different repairs over time. So last week, I put it in the washing machine to clean it again…and it fell apart. It had such large holes and tears that I could no longer tape it together. It is a dead shower curtain. Frankly, I’m ready to get something plastic-free anyway.

Chemicals in Plastic/Vinyl Shower Curtains

In 2008, the Center for Health, Environment and Justice released a study after testing PVC shower curtains purchased at big box retailers. “All of the curtains contained cancer-causing volatile organic compounds [VOCs], phthalates, organotins (nervous system toxicants) and one or more of the heavy metals lead, cadmium, mercury and chromium.”² As many as 108 VOCs can be emitted from a PVC shower curtain.

Though newer plastic shower curtain liners are supposedly less toxic, because of reports like that, there are still two major problems with them. First, I can still smell that SMELL. Since I don’t really know what my family is breathing and smelling from a potentially new plastic/vinyl shower curtain, I’d just rather avoid it. Second, it is made of PLASTIC! Call it vinyl, call it PEVA, call it whatever you’d like – but the fact is, is that it is a plastic product with no recyclability or afterlife use. [Side note: an undamaged old shower curtain could potentially be used as a drop cloth when painting or doing other tasks where you don’t want to damage or litter the floor. But then it still will have to be discarded at some point.]

So what are the alternatives?

The alternatives are organic cotton, hemp, and linen – all cloth materials. Hemp is evidently mold-resistant, so that’s the type I will most likely buy someday. On a discussion board at myplasticfreelife.com, a guest suggested rubbing beeswax on a cloth curtain to repel water and mold.³ I’ve also seen shower curtains made out of recycled sailcloth on sites like Etsy and Second Wind Sails. These are cool and something I’d like to try someday, but they are expensive.

Since the dead shower curtain liner was actually just a liner for us, I’m going to simply keep using the fabric shower curtain that I already have and hope that it doesn’t get ruined. I am seriously considering trying the beeswax method. If I do, I promise to update this article! (Please read my update here.)

What are your ideas to replace a plastic shower curtain, or what have you tried? I would love to know – please leave me a comment below!
