For years, Tom Raviv, a seasoned professional in the demanding world of mergers and acquisitions, meticulously examined the ingredients of his daily sustenance. He scrutinized snack bars and protein options, ensuring they aligned with his commitment to mindful consumption. Yet, a ubiquitous daily habit entirely escaped his vigilant scrutiny: chewing gum. It wasn’t until a simple, yet profound, question struck him that the veil of unawareness was lifted. Why, he pondered, did he invest so much effort in understanding the composition of his food while completely overlooking what he was placing in his mouth for extended periods?
The answer, unearthed through a quick digital search, was startling. The primary component in the vast majority of chewing gum, often cryptically labeled as "gum base," is derived from petroleum-based plastics and synthetic polymers. These are the very same materials that constitute everyday items like plastic bags and beverage bottles. Disturbingly, academic research, including a notable study from Queen’s University Belfast, suggests that a single piece of chewing gum can release an astonishing number of microplastic particles into saliva, potentially reaching up to 250,000. This revelation prompted Raviv’s immediate concern: "I was really shocked," he admitted in a recent interview with The Spoon. "I didn’t want to be chewing on plastic and realized the stuff must be going into my body."
This pivotal moment of realization served as the genesis for Milliways, a company Raviv founded in 2021. While still immersed in his demanding full-time role, Raviv dedicated his evenings and weekends to the nascent venture. His apartment transformed into an impromptu research and development laboratory as he grappled with the challenge of creating a genuinely plastic-free chewing gum. A significant early hurdle involved sourcing a viable alternative to synthetic gum base. After receiving a kilogram of natural tree sap – a traditional chewing material utilized for centuries – Raviv, through persistent effort and collaboration, eventually found partners capable of transforming this raw, natural ingredient into a modern, palatable gum product. The result was Milliways’ inaugural offering: a plant-based gum crafted from tree sap, boasting a minimalist ingredient list of no more than seven naturally derived components.
Raviv and Milliways are not isolated voices in raising awareness about the pervasive presence of plastic in conventional chewing gum. The potential health implications of ingesting microplastics have become a growing area of scientific investigation in recent years. A peer-reviewed study published in the esteemed Journal of Hazardous Materials unequivocally demonstrated that the act of chewing gum can lead to the release of significant quantities of microplastics and nanoplastics into a person’s saliva. For Raviv, these findings serve as a powerful validation of his 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 stated. "It’s like chewing on a plastic straw. It doesn’t just disappear."
Beyond the immediate health concerns, Raviv and his growing cohort of advocates emphasize the critical issue of transparency in product labeling. They argue that if consumers were fully aware that their daily chewing gum habit is intrinsically linked to plastic consumption, the choice would be far less appealing for the majority. This message appears to be resonating powerfully within the consumer market and the industry itself.
Significant Investment Signals Market Shift
This growing awareness has culminated in a significant financial milestone for Milliways. The company recently announced the successful closure of a $3 million funding round. Notably, this investment was spearheaded by prominent figures from the global gum industry, including Mehmet Yüksek, former CEO of Perfetti Van Melle North America, and Leon Amram, former owner of Intergum. Their participation underscores a perceived shift within the industry towards more sustainable and health-conscious product development.

The influx of capital signifies robust confidence in Milliways’ innovative approach and its potential to disrupt the established chewing gum market. Since its initial launch in the U.S. just over a year ago, the brand has experienced rapid expansion, securing shelf space in more than 2,000 retail locations nationwide. This swift market penetration suggests a strong consumer demand for alternatives to conventional plastic-based gum.
The Science Behind the Concern: Microplastics in Everyday Products
The scientific community’s increasing focus on microplastics has brought the composition of everyday products under intense scrutiny. Traditional chewing gum’s primary "gum base" is a complex blend of synthetic polymers, resins, and plasticizers, often derived from petrochemical sources. These non-biodegradable materials are designed for durability and elasticity, qualities that unfortunately translate into their persistence in the environment and potential for ingestion.
- Composition of Conventional Gum Base: While specific formulations vary, common ingredients include polyvinyl acetate (similar to wood glue), polyethylene (used in plastic bags), and various synthetic elastomers and waxes. These are not digestible and are intended to be non-toxic for the duration of chewing.
- Mechanism of Microplastic Release: The physical action of chewing, involving mastication and saliva exposure, can gradually break down the synthetic polymers in the gum base. This process releases microscopic particles that are then suspended in saliva.
- Ingestion and Potential Health Effects: Studies suggest that a significant portion of these microplastics can be swallowed during the chewing process. While the long-term health effects of microplastic ingestion are still under active investigation, concerns include potential inflammation, disruption of cellular processes, and the possibility of carrying harmful chemicals into the body. Research published in journals like Environmental Science & Technology and Nature Food are continuously exploring these avenues.
A Historical Perspective: From Natural Resins to Petrochemical Polymers
The journey of chewing gum from its ancient origins to its modern, plastic-infused form provides crucial context for Milliways’ mission. For millennia, humans chewed on natural resins and saps obtained from trees. For example, the mastic tree of Greece has yielded mastic gum for over 2,400 years, prized for its flavor and perceived dental benefits. Similarly, indigenous cultures in North America chewed on spruce tree sap. These natural materials were biodegradable and derived from renewable resources.
The advent of synthetic polymers in the early 20th century revolutionized many industries, including confectionery. The development of more stable, cost-effective, and versatile synthetic gum bases offered manufacturers greater control over texture and longevity. This shift, while commercially successful, gradually led to the widespread use of petrochemical-derived plastics in a product that is, by its very nature, often disposed of in the environment and, as revealed, ingested by consumers.
Milliways’ Approach: A Return to Nature, Enhanced by Innovation
Milliways’ commitment to a plastic-free future for chewing gum is rooted in a philosophy of returning to natural, sustainable ingredients while leveraging modern food science to create a superior product.
- Plant-Based Gum Base: The core innovation lies in the use of natural tree sap and other plant-derived ingredients to create a gum base that mimics the desirable chewing properties of traditional gum without the plastic. This involves careful formulation and processing to achieve the right texture, elasticity, and flavor retention.
- Minimalist Ingredient Philosophy: By limiting the ingredient list to a maximum of seven naturally derived components, Milliways prioritizes simplicity and transparency. This approach aims to reduce potential allergens and provide consumers with a clearer understanding of what they are consuming.
- Sustainability Beyond Ingredients: The company’s focus extends to the entire product lifecycle, aiming for biodegradable and compostable packaging solutions, further reducing environmental impact.
Broader Implications and Future Outlook
The success of Milliways and the significant investment it has attracted signal a broader trend toward conscious consumerism and a demand for greater environmental and health responsibility from manufacturers. The implications of this shift are far-reaching:
- Industry Transformation: Milliways’ model could pressure larger, established gum manufacturers to re-evaluate their product formulations and invest in sustainable alternatives. This could lead to a significant reduction in plastic waste generated by the chewing gum industry.
- Consumer Education: The company’s advocacy for transparency is crucial in empowering consumers to make informed choices. As awareness grows, demand for plastic-free options is likely to increase across various consumer product categories.
- Innovation in Food Science: The challenge of creating palatable and functional plant-based alternatives to established synthetic ingredients drives innovation in food science and material engineering. Milliways’ success demonstrates the potential for groundbreaking advancements in this field.
Tom Raviv’s personal journey from an unexamined habit to a mission-driven entrepreneur encapsulates the power of individual awareness to spark significant change. "It’s not always the big changes," he reflected. "Sometimes it’s the little things you do every day. Those things add up, for better or worse." With the backing of industry veterans and a growing consumer base, Milliways is poised to redefine the future of chewing gum, proving that even the smallest daily choices can have a profound and positive impact. The company’s momentum confirms a palpable shift in consumer priorities, where health, sustainability, and transparency are increasingly becoming non-negotiable factors in purchasing decisions.
