Breaking Down Microplastics: A Growing Concern for Health

Plastic has long been hailed as a miracle material, transforming industries and shaping modern life. First invented in 1907 by Belgian chemist Leo Baekeland, Bakelite was the first fully synthetic plastic, marking the start of an era where lightweight, durable, and versatile materials revolutionized manufacturing. From medical devices to aerospace engineering, packaging to electronics, plastic quickly became an essential part of daily life, making products cheaper, more accessible, and longer-lasting.
The post-war boom of the 1950s and 60s saw plastic production soar, introducing polyethylene, polypropylene, and polystyrene—materials now used in everything from food containers to clothing. Plastic’s ability to replace natural materials helped conserve resources like ivory, tortoiseshell, and wood, while its use in medicine—from sterile syringes to artificial heart valves—has saved countless lives.
But the very properties that make plastic so useful—its durability and resistance to decay—have also led to an environmental crisis. Unlike organic materials, plastic doesn’t truly decompose; instead, it breaks down into smaller and smaller fragments. Today, microplastics (particles smaller than 5mm) are found everywhere—in oceans, soil, air, and even inside our bodies.
Floral Foam and Microplastic Pollution
Traditional floral foam emerged in the mid-20th century as a game-changing tool for florists, offering a water-absorbing, easy-to-shape base for arrangements. However, unlike hard plastic items that can be collected and recycled, floral foam is particularly problematic when it comes to microplastic pollution.
Made from phenol-formaldehyde, a brittle plastic, floral foam crumbles into tiny, waterborne microplastics. Once washed down the drain or disposed of after use, these particles enter rivers, drainage systems, and oceans—where they cannot be collected or filtered out. This pollution persists in the environment, contaminating marine ecosystems and entering the food chain, posing risks to wildlife and human health.
What compounds the issue is that floral foam has no viable end-of-life solution. Unlike some plastics that can be recycled or repurposed, floral foam almost exclusively ends up in landfill, where it continues to break down into microplastics over time, further contributing to long-term environmental pollution.
Microplastics in the Human Brain: A Growing Concern
Microplastics have been making headlines for their presence in oceans, food, and even the air we breathe—but a new study published in Nature Medicine reveals an even more alarming finding: microplastics have been detected in human brains. Scientists have long speculated that these tiny plastic particles could enter the body through food, water, and air, but this study confirms they accumulate in vital organs, including the liver, kidneys, and brain.
How Microplastics Enter the Brain
Microplastics and nanoplastics (MNPs)—some as small as 1 nanometer—come from broken-down plastic waste, synthetic fabrics, and even cosmetic products. Once in the environment, they contaminate water sources and food chains, eventually making their way into the human body.
The study found that polyethylene (PE)—a plastic commonly used in packaging and household products—was the most prevalent polymer detected in human brain tissue. Using advanced imaging techniques, researchers identified plastic particles lodged in cerebrovascular walls and immune cells, raising concerns about how these foreign materials interact with brain function.
Microplastics and Brain Health: A Potential Risk?
One of the study’s most striking findings was the higher concentration of microplastics in the brains of individuals diagnosed with dementia compared to those without the condition. While this does not prove microplastics cause neurological diseases, it suggests a potential link between plastic exposure and brain health. The concern is how these tiny plastic particles might trigger inflammation, disrupt cellular processes, or interfere with brain function. Previous research has already suggested that microplastics in the bloodstream could contribute to cardiovascular issues, making their impact on the nervous system a growing area of concern.
Are Microplastics Accumulating Over Time?
The study compared human tissue samples from 2016 and 2024 and found that the concentration of microplastics had significantly increased in the more recent samples. This suggests that as plastic pollution rises, so does human exposure—and potentially, the accumulation of plastic particles in the body.
A Shift Towards Plastic-Free Alternatives
As awareness of plastic pollution grows, new plastic-free materials are emerging across industries, offering sustainable alternatives to traditional plastics. Innovations in biodegradable packaging, plant-based textiles, and compostable biomaterials are helping to create a circular economy. Mycelium-based packaging, made from fungal networks, provides a natural, compostable alternative to polystyrene. Seaweed-derived bioplastics are being developed for food packaging, offering a fully biodegradable solution without contributing to microplastic pollution.
We are incredibly proud to be the world's first compostable floral foam, providing florists with sustainable options. Phoam offers a safe alternative to traditional phenolic foam, providing flexibility in the way florists work.
Equally, we take pride in being part of an emerging green economy, driving a shift toward sustainable materials that prove practical, planet-friendly alternatives can replace plastics without compromising performance. As consumers, businesses, and industries continue to adapt, reducing plastic waste—particularly microplastic pollution from floral foam and disposable plastics—is essential for a cleaner, healthier future.
