That plastic is now showing up on shorelines, forming islands in oceans, and generating mountains of translucent trash on land. Around 700 species of animals in the sea have been found to interact with plastic daily. Companies across every industry face pressure to reduce the amount of plastic they produce. Seventy-two percent of the world’s largest have made voluntary commitments to reduce their plastic waste, according to a Duke University analysis. One industry, in particular, has greatly benefited from advancements in single-use plastic technology: the medical industry. Only in recent years have businesses and academics in the field begun to talk about minimizing their impact on our environment like beverage manufacturers and other consumer goods-producing businesses. Medical Technology Schools analyzed academic studies published in the National Library of Medicine, the American Medical Association, and news reports to shed light on the medical community’s use of plastics through history, their environmental problems, and proposed solutions to reduce their impact. And the impact can be significant. A single hospital patient generates nearly 34 pounds of waste a day–as much as a quarter of it is plastic. The COVID-19 pandemic only worsened the problem. Plastic medical waste booms during COVID-19 LookerStudio // Shutterstock The pandemic pushed hospital capacity to the brink and led to a massive increase in personal protective equipment and medical supply usage. Medical-grade masks and other protective equipment like face shields, made mostly of nonrenewable plastics, were in high demand. In 2020, the World Health Organization estimated that the international need for PPE manufacturing would boost 40% to address the public health crisis. Hospitals needed an estimated 89 million masks, 76 million gloves, and 1.6 million goggles every month of the pandemic. To date, nearly 677 million COVID-19 vaccine doses have been administered, each requiring their own plastic syringe, according to data from the Centers for Disease Control and Prevention. Global consulting firm Frost & Sullivan estimated that the U.S. would produce a year’s worth of medical waste in just two months due to the pandemic. The World Economic Forum warned that the COVID-19 crisis threatened to “stall and even reverse progress” to reduce large plastic waste. It’s a challenge researchers acknowledge today as they search for solutions. Convenience gives way to cleanliness InkheartX // Shutterstock Plastics introduced an era of ultraconvenience to the world. It makes our clothes. It’s made bike helmets and airbags possible. And it’s a cheap material to produce, meaning it’s cheap for consumers too. Almost as importantly, it’s durable and incredibly easy to make into complex shapes–a trait that helped plastics invented in the mid-20th century quickly replace more expensive metal and wooden goods. That adoption extended to the medical field, where the single-use nature of plastics represented a move toward more hygienic tools for physicians and hospitals. But it wasn’t plastic’s sanitary qualities that the industry first latched onto. Like so many other technical advancements, convenience and cost were the initial driving factors. That they were more conducive to creating a sterile environment for patients was a benefit that health care began to tout closer to the end of the 20th century. PVC, or polyvinyl chloride, replaced glass bottles previously used to hold IV solution and replaced rubber tubing used throughout hospital settings. Plastic has also become the go-to material for making syringes and catheters. Plastic products are generally made from chemicals derived from the oil and natural gas refining process. Chemists use those byproducts to create synthetic materials with malleable and durable chemical structures. The low cost of these materials has helped medical device-makers support better health outcomes for communities across the U.S. since the 1900s. No longer was health care priced at rates only the elite could afford–it was accessible to a much larger swath of the public. In the last decade, the U.S., in particular, has emerged as a massive market for medical plastics. The country generally accounts for nearly half of the global market for medical devices. Plastic’s durability is not only a benefit but a detriment to the environment, as the material can take many years to deteriorate when it enters landfills or trashes oceans. Estimates vary widely, but scientists ballpark that depending on the kind of plastic and the environment in which it decomposes, it could take dozens to thousands of years to break down entirely. Waste could pile higher, faster in the coming years
Single-use plastics revolutionized the medical industry. Now, they're raising concerns about sustainability.
