A bamboo toothbrush deconstructed: bamboo handle, paper packaging box, plant-based nylon bristles and plant-based wrapper. It also comes with disposal instructions.

“Bamboo handle and paper box are compostable.” Easy.

“Nylon bristles are not compostable but can be recycled…ask your local recycling facility about the best way to recycle the bristles.” More difficult, but still possible.

“Plant-based wrapper is compostable in commercial facilities only (ASTM D6400). Appropriate facilities may not exist in your city.” Evidently, this might not be possible at all.

Given labels advertising this brush’s sustainable and biodegradable qualities, as well as the seal of USDA biobased certification, this fine print on the packaging is jarring. Doesn’t “biobased” mean the toothbrush will eventually decompose on its own no matter its environment? This is the type of worry-free, bioplastic future we are moving towards, right?

Bioplastics are more complicated than their public image suggests. “Bioplastic” is an umbrella term for a plastic material that is biobased, or made partially from biomass like corn or cellulose, biodegradable, or able to break down into organic components, or both. A caveat, however, is that biobased materials are not necessarily biodegradable, nor are all biodegradable materials guaranteed to biodegrade. Bioplastics that end up in anaerobic landfills, cold oceans, or even among recyclable plastics fail to degrade and may do the same harm, disrupting the same natural processes as do traditional plastics. In cases like the toothbrush’s plant-based wrapper, even materials listed as biodegradable require extremely specific conditions like those found in industrial composting facilities in order to break down properly, and this proper disposal may not be feasible for the common consumer. So that biobased plastic bag that is reassuringly printed green with images of leaves? It might be more for your psychological benefit than for the benefit of the environment.

In fact, we are much farther from a green reality than we think we are. Even the United Nations has recognized that biodegradable plastics are not a viable alternative: their current production of 4 million tons per year amounts to only a fraction of a percent of the staggering 9.1 billion tons of plastic that have been produced in the past 70 years. Moreover, their complicated disposal requirements don’t inspire much confidence that even a respectable proportion of that tiny amount will degrade as expected. Instead, we must face the uncomfortable reality that virtually all of the plastic that we have created and used (used, by the way, for an average of 12 minutes) still exists, infiltrating our land, animals, and bodies. Seventy-nine percent of that plastic waste has been left to fester in landfills, while 12 percent has been burned. Incineration does eradicate plastic, but it also expels toxic fumes and carcinogens dangerous to public health and the environment. A measly 9 percent of global plastic has been recycled.

It’s easy to blame the low rates of plastic recycling on consumer ignorance or apathy; it is harder to recognize that the complexities of plastic production by the plastic industry are larger contributors to the issue. Even for the most knowledgeable consumer, always getting it right is impossible. Polyethylene terephthalate, high-density polyethylene, polyvinyl chloride, low-density polyethylene, polypropylene, polystyrene, polycarbonate, polylactide, acrylic, acrylonitrile butadiene, styrene, fiberglass, and nylon: How can the average recycler be expected to know the difference between regular plastics, much less bioplastics?

It’s easy to blame the low rates of plastic recycling on consumer ignorance or apathy; it is harder to recognize that the complexities of plastic production by the plastic industry are larger contributors to the issue.

With the infeasibility of efficient bioplastic use and recycling, it is clear that the only effective solution to our plastic crisis is for companies to produce less plastic in the first place. This point is rarely present, however, in common conversations about waste, which tend to focus on consumer responsibilities to make individual lifestyle changes. The zero-waste lifestyle, which has gained traction in recent years and has bolstered demand for sustainable alternatives like metal straws and refillable shampoo bottles, is a powerful movement rethinking the individual’s responsibility to consume consciously. However, many leaders of the movement have been criticized for failing to acknowledge that having non-plastic options also relies on privilege, since access to bulk-food stores and fresh unpackaged produce is not equal. Most importantly, these individual actions have a minuscule impact on plastic production, which is only projected to increase by 40 percent in the next ten years.

Bioplastics and the plastic industry

Aware of the heightened public concern over the negative environmental effects of plastic production, the industry can no longer deny the externalities of its activity. In response to this backlash — labeled an “industry challenge” in a recent J.P. Morgan Chase report — the plastic industry has begun to portray recycling and bioplastics as key components in their “embracing [of] an expanded definition of product stewardship that includes dealing with plastics waste.

Industry leaders deceptively lobby on Capitol Hill for more recycling infrastructure funding, basking in their declared concern over the environment while they use recycling as justification for trying to integrate plastic into new infrastructure applications like pipes. They neglect to mention that unlike the endlessly recyclable metals traditional pipes are built with, recycling plastic only delays its ultimate fate as pollution, since plastic can only be recycled a few times before it is unusable.

The Plastics Industry Association (PLASTICS), a trade association that represents some of the largest corporate plastic polluters like Coca-Cola, PepsiCo, and Nestlé, hosts misleading social media campaigns about the simple, bright future of bioplastics. Nowhere do they adequately acknowledge the complexities of sustainably disposing of them and the need for a certain amount of new petroleum-based plastic in many bioplastic products.

Among all of the industry’s supposedly environmentally conscious declarations, the radical notion of producing less plastic cannot be found.

This should come as no surprise. Since the first waves of opposition, the plastics industry has engaged in underhanded ways to protect its business and to convince the public that consumers are responsible for plastic pollution. In response to Vermont’s 1953 Beverage Container Law, which banned the new, more profitable single-use beverage bottles in favor of reusable containers that companies would be responsible for reusing or recycling, notorious companies like Phillip Morris and Coca-Cola formed the non-profit Keep America Beautiful (KAB). KAB has since released decades of greenwashing propaganda that have been nothing short of culture-defining. From coining the term “litter-bug” and releasing PSAs that blamed consumers for plastic pollution, to lobbying against any type of legislation that would increase producer accountability or threaten their profit margins, KAB has effectively written the popular discourse and regulatory laws to serve themselves.

Among all of the industry’s supposedly environmentally conscious declarations, the radical notion of producing less plastic cannot be found.

Today, KAB is still sponsored by some of the most notorious environmentally damaging corporations, like H&M, The Clorox Company, Dow, Northrop Grumman, McDonald’s, Coca-Cola, PepsiCo, and Nestlé. They have shifted their agenda from fighting bottle bills to fighting the burgeoning plastic bag ban movement, which has successfully decreased the demand for plastic bags by the tens of billions in the cities and states that have already passed such bans. Under various campaign and organization names like Save the Plastic Bag Coalition and the American Progressive Bag Alliance (the lobbying faction of PLASTICS), the plastics industry has filed lawsuits against local governments that have banned plastic bags and has spent millions of dollars to pass preemptive state-wide plastic ban laws that prevent local governments from banning plastic bags in their cities.

In the face of such sinister manipulation by the plastics industry, it almost feels like a voluntary acceptance of their narrative to blame the consumer. Yet, when I dropped my bamboo toothbrush on the dirty dorm bathroom floor at 2 am, threw it away in disgust without a second thought, and only recalled the packaging’s specific instructions a few days later, the guilt was immense. I felt like a hypocrite for urging my family to transition to more sustainable options when I couldn’t even sustainably dispose of them myself. But let’s consider if I had remembered. As a current resident of NYC, I have more access to sustainable infrastructure and programs than most of the nation, but there is still no available information online for either recycling nylon bristles nor compostable bio-based wrappers in my immediate area. Even if I had wanted, proper disposal of my bamboo toothbrush—the most sustainable option on the current market—would have been next to impossible.

It’s true that we all have a duty to reduce waste to the best of our ability and to push our society into a circular economy, but the guilt we are conditioned to feel when we fail is also deceptive and unfair. Consumers should not be expected to solve plastic pollution, especially considering that the crisis is only being perpetuated by the plastics industry. Most of our guilt is not our own but is manufactured and molded by the plastics industry in the same way that it manufactures its own products and molds public opinion to release it from any obligation over the remnants of its business.

We must remember that bioplastics, while promising, are not at a stage for us to place blind faith in their ability to transform the plastic crisis and that recycling does nothing to prevent all produced plastic from eventually becoming useless trash. We cannot allow the plastics industry to continually greenwash and distract us from the truth: the only solution is for the plastic industry to take responsibility for the byproducts of its profit and to reduce its own production levels for the health of our plastic-choked planet.

I just found 10 composting facilities in NYC… Most bioplastics are not meant to be biodegradable. Being biobased means that only a percentage of the part is plant based and the rest is traditional plastic. The goal for this is to use less traditional plastic.. which is exactly what it does.

I don’t know who hurt you, but attacking companies and people that want to make a positive impact on the planet does not help. We’ve got a similar goal, but clearly a different route to get there.

Hi Sabrina, we think you did a nice job writing this and you clearly researched the industry.
Although well written I think it is short sighted, I couldn’t agree more with Andrew.

The industry has seen significant change and growth and bioplastics are continue to develop with more sustainable approaches. There is resin being developed from all types of waste and renewable raw materials. In addition to development of technologies, composting only continues to grow across the country.

Policymakers are aware that with Zero Waste goals and composting mandates (New York, Massachusetts E tc) will get closer to proper waste reduction.
A combination of both solutions will lead to less waste.

Ofcourse we believe in reusing everything as much as possible but we also believe in good business and taking the steps to be better while not stopping development of those who are working towards the change we need in the world.

The best plastics are those that can be recycled within our current infrastructure where there is heavy demand — #1 PET and #2 HDPE. We in the industry know that bio-based plastics were never meant to “disappear” into the environment and “bioplastics” is just a green misnomer used to make plastic-ignorant consumers feel good. Use the real deal — PET and HDPE, and recycle it. The rest? Incinerate it which captures the high BTU value of plastics (which has the equivalent of coal) and provides energy. Plastics is the most eco-friendly, energy efficient material on the planet both in terms of manufacturing/processing and in terms of products — for example vehicles that are lightweight and more energy efficient than alternatives were back in the 1950s, 60s and 70s. Bio-plastic is a farce. So are bamboo tooth-brush handles and other products that claim compostability. Most composting facilities — the majority in fact — take only food and yard waste. They don’t take bio-plastic products that claim compostability. Recycling is the optimum method of capturing the value of plastic materials, reducing the need for new, virgin resins, and saving energy in the process. Banning useful, reusable plastic items such as retail bags is not the answer because the alternatives have been proven in many studies to be worse! Study up on how cotton is produced and processed — including the use of aerial defoliant spraying! Plastic is Fantastic!

While I’d completely agree re biodegradability of the outer wrapper is not great (still sitting in my garden bed waiting to biodegrade), it does compost. Furthermore they no longer package the brush with the biodegradable plastic, it’s now packaged in a cardboard box only.

If you want to help with the plastic/waste problem you MUST compost – regardless of where on the planet you live. Find a way. It’s really not that difficult.

Yes you have to remove the bristles, I don’t personally agree with the “recyclable” claim and think it’s unnecessary to state. But they are less plastic than the majority of Bamboo Toothbrushes. It’s really not that difficult to remove them, even if you don’t, and you’re sending the whole bush to landfill it’s 100x better than the plastic alternative.

Yes biobased can be misconstrued, but if you do the research, it does not mean it’s biodegradable, and it never claims to mean that.

Keep moving forward with your plastic reduction, the guilt will turn into pride of your accomplishments, and you can then use your journalism skills to convince others to join you in your quest to free the plant of plastic.

Good article.Awareness regarding biodegrability and green washing are important and only those things that can be bio degraded by the user or manufacturer or those responsible for safety should be allowed to be used.

I’ve just found the bamboo toothbrush and was wondering about it’s filament material, i’m glad i did search for more information because your article showed me more about the industry than what i would’ve realised on my own meditation.
I’ve read some people comments, and i gotta say that not all companies related to the “green movement” are trying to deceive public conscience and opinion but that doesn’t mean they aren’t doing it…this sentence comes back to my mind:

“Hell is full of good intentions or desires”.
-Bernard de Clairvaux (1091-1153).

I cant blame people who try to reduce the pollution by using alternative materials and i cant blame them for feeling better that way, because deep inside we all know that whats left on the other side of the street is dire desperation. We all know that when we’re buying “Eco-friendly” stuff, sometimes there’s a very little tiny voice whispering in our ear: “maybe not buying it at all would be better for the environment you know?” We’ve been raised in a consumer world, and we’re gonna need generations before we manage to teach our children that this isn’t the way, no matter what economic, political, or sophists doomsayers tell us. This world we live in is all we know but, it definitely is not the only way to live with peace and fulfilment.

Green washing is one of those unfortunate buzz words that doesn’t really mean anything concrete. Here it’s used to label a process which wasn’t made completely efficient yet as a scam. With the benefit of time, we now see that most of the companies offering these toothbrushes (including the one mentioned in the article) package their product in 100% bio degradable cardboard. It’s unfortunate that there isn’t a completely bio degradable bristle yet but if that’s really a life threatening problem for someone, they should invent it. Throwing away some nylon is certainly better than throwing away an entirely plastic toothbrush and it’s plastic package.

There is an alternative bristle which has existed for hundreds of years (though not always for teeth): boar bristles.

yhea but atleast the handle is made out of wood and not plastic so its better then all the other thoothbrushes on the market.
