For decades, the simple act of chewing gum has been a ubiquitous habit, a discreet companion during commutes, study sessions, and moments of quiet contemplation. Yet, beneath the minty freshness and satisfying chew lies a hidden environmental and potential health concern: the pervasive presence of microplastics. Tom Raviv, a former mergers and acquisitions professional, stumbled upon this unsettling reality, a realization that has since propelled him to found Milliways, a company dedicated to revolutionizing the gum industry with plant-based, plastic-free alternatives. This shift from a personal awakening to a burgeoning business underscores a growing global awareness of the microplastic crisis and its insidious reach into everyday consumer products.
The Journey from Discovery to Innovation
Raviv’s journey began not with a grand environmental mission, but with a moment of introspection during a demanding career. "Working long hours in mergers and acquisitions, I’d read the ingredients on snack or protein bar wrappers as I grabbed them between meetings," he recalled in a recent interview with The Spoon. "One product, however, escaped my scrutiny entirely." That product was chewing gum. "I’d grab a pack of gum at the checkout, run back to my desk, and never once thought about what I was actually chewing on," Raviv admitted.
This seemingly innocuous oversight was challenged by a simple yet profound question: why did he meticulously scrutinize the ingredients of his food but remain oblivious to the composition of his gum? A quick search revealed a startling truth: the primary ingredient in most chewing gum, often vaguely listed as "gum base," is a complex mixture derived from petroleum-based plastics and synthetic polymers. These are the same materials that form the backbone of plastic bags and bottles, products now widely recognized for their environmental persistence. The implications of this discovery were amplified by emerging academic research. Studies have indicated that a single piece of chewing gum can release an astonishing number of microplastic particles into saliva, with some estimates reaching as high as 250,000.
"I was really shocked," Raviv stated. "I didn’t want to be chewing on plastic and realized the stuff must be going into my body." This personal revelation ignited a passion that led Raviv to found Milliways in 2021. While still employed full-time, he dedicated his evenings and weekends to transforming his apartment into an impromptu research and development laboratory. The initial challenges were significant, involving sourcing and experimenting with raw materials. A pivotal moment arrived when a supplier provided a kilogram of natural tree sap, a traditional masticatory substance used for centuries. Through persistent effort and collaboration, Raviv eventually partnered with individuals who could help translate this ancient ingredient into a modern gum product. The result was Milliways’ first offering: a plastic-free gum crafted from plant-based tree sap, boasting a concise ingredient list of no more than seven naturally derived components.
The Growing Concern Over Microplastics in Gum
Raviv and Milliways are not the sole voices highlighting the pervasive issue of plastic in chewing gum. Scientific scrutiny into the health implications of microplastic ingestion has intensified in recent years. A significant peer-reviewed study published in the Journal of Hazardous Materials provided concrete evidence of this phenomenon. The research demonstrated that the act of chewing gum can lead to the release of substantial quantities of microplastics and nanoplastics into a user’s saliva. These findings strongly corroborate Raviv’s initial concerns.
"When you’re chewing something made from plastic and grinding it down in your mouth, it’s no surprise you’re ingesting it," Raviv explained, drawing a stark analogy: "It’s like chewing on a plastic straw. It doesn’t just disappear." The long-term health effects of chronic microplastic ingestion are still a subject of ongoing scientific investigation. However, initial research suggests potential links to inflammation, oxidative stress, and disruption of cellular processes. The sheer volume of microplastics released by chewing gum, coupled with the frequency with which many individuals chew gum daily, raises legitimate questions about cumulative exposure and its potential impact on human health.
Beyond the direct health concerns, the lack of transparency in product labeling has become a focal point for Raviv and other advocates. He argues that if consumers were fully aware that their chewing gum is, in essence, plastic, the demand for such products would likely diminish. This sentiment resonates with a growing segment of the consumer base that is increasingly prioritizing sustainability and health-conscious choices.
Industry Response and Market Momentum
The message of transparency and healthier alternatives appears to be gaining traction within the market. This month, Milliways announced a significant milestone: a $3 million funding round. The investment was notably led by prominent figures from the global gum industry itself, including Mehmet Yüksek, former CEO of Perfetti Van Melle North America, and Leon Amram, former owner of Intergum. This endorsement from industry veterans suggests a recognition of the shifting consumer landscape and the potential of innovative, sustainable gum formulations.
Since its launch in the United States just over a year ago, Milliways has experienced rapid expansion, securing placement in more than 2,000 retail stores nationwide. This impressive growth trajectory underscores a growing consumer appetite for products that align with their values, particularly concerning environmental impact and personal well-being. The company’s success indicates that the perceived inconvenience of traditional gum is being outweighed by the desire for a healthier and more environmentally responsible option.
The Broader Implications of the Microplastic Crisis
The Milliways story serves as a microcosm of a larger global challenge: the pervasive nature of plastic pollution. Microplastics, defined as plastic particles less than 5 millimeters in length, are now found in virtually every corner of the planet, from the deepest ocean trenches to the highest mountain peaks, and even within the human body. They originate from the breakdown of larger plastic items, as well as from the direct release of microfibers from textiles and microbeads from personal care products.
The implications of this widespread contamination are multifaceted. Environmentally, microplastics can be ingested by wildlife, leading to physical harm, starvation, and the transfer of toxic chemicals through the food chain. Ecologically, they can alter soil and water properties, impacting plant growth and aquatic ecosystems. For human health, while research is still in its nascent stages, concerns range from physical irritation and inflammation to potential endocrine disruption and other long-term health consequences.
The gum industry, with its daily and widespread use, represents a significant, often overlooked, source of microplastic release. While the focus has often been on larger plastic waste items, the cumulative effect of millions of pieces of gum discarded daily, coupled with the microplastics released during consumption, contributes to the overall microplastic burden.
The Way Forward: Innovation and Consumer Choice
The success of Milliways and the growing awareness surrounding microplastics in gum signal a potential paradigm shift. This movement is not solely about eliminating a single product but about fostering a broader culture of conscious consumption. It encourages consumers to question the composition of everyday items and to seek out alternatives that are better for both their health and the planet.
Raviv’s philosophy encapsulates this broader perspective: "It’s not always the big changes," he stated. "Sometimes it’s the little things you do every day. Those things add up, for better or worse." This sentiment highlights the power of individual choices to collectively drive significant change. As more companies embrace sustainable practices and consumers demand greater transparency, the landscape of product development and consumption is poised for transformation. The journey from a personal realization about chewing gum to a burgeoning industry focused on plastic-free alternatives is a testament to the growing power of informed consumerism and innovative entrepreneurship in addressing some of the most pressing environmental challenges of our time. The future of chewing gum, and indeed many other everyday products, may very well be plastic-free.
