The evolution of the plastic bottle from amazing to scourge of land and sea has played out inside of a generation.
The moment the modern plastic beverage bottle changed the world’s drinking habits is difficult to pinpoint. The day New York supermodels began carrying tall bottles of Evian water as an accessory on fashion show catwalks in the late 1980s surely signaled the future ahead. Billions of bottles were sold on the promise that bottled water is good for hair and skin, healthier than soft drinks and safer than tap water. And it didn’t take consumers long to buy into the notion that they needed water within reach virtually everywhere they went.
What sets bottles apart from other plastic products born in the post-World War II rise of consumerism is the sheer speed with which the beverage bottle, now ubiquitous around the world, has shifted from convenience to curse. The transition played out in a single generation.
“The plastic bottle transformed the beverage industry and it changed our habits in many ways,” says Peter Gleick, co-founder and president emeritus of the Pacific Institute in Oakland, California, and author of Bottled and Sold: The Story Behind Our Obsession with Bottled Water.
“We’ve become a society that seems to think if we don’t have water at hand, terrible things will happen. It’s kind of silly. It’s not as though anybody died from thirst in the old days,” he says.
By 2016, the year sales of bottled water in the United States officially surpassed soft drinks, the world had awakened to the burgeoning crisis of plastic waste. The backlash against the glut of discarded bottles clogging waterways, polluting the oceans and littering the interior has been swift. Suddenly, carrying plastic bottles of water around is uncool.
What is cool is wearing them: Hip fashion translates into designer clothes made of recycled water bottles. There’s even a growing market of luxury, stainless steel refillables, including a limited-edition bottle covered with thousands of Swarovski crystals that sells for almost $2,000.
Plastic bottles and bottle caps rank as the third and fourth most collected plastic trash items in the Ocean Conservancy’s annual September beach cleanups in more than 100 countries. Activists are zeroing in on the bottle as next in line for banning, after plastic shopping bags. The tiny towns of Concord, Massachusetts and Bundanoon, Australia already have banned bottles, as have numerous public parks, museums, universities, and zoos in Europe and the United States.
The developing world—where 2.2 billion people still do not have access to clean drinking water, according to the United Nations, and bottled water is often the only safe option—is getting out ahead of the problem. In June, Kenya announced a ban on single-use plastics at beaches and in national parks, forests, and conservation areas, effective in June 2020, and the South Delhi Municipal Corporation banned disposable water bottles in all city offices.
A brief history
Consumers have been drinking bottled beverages for more than a century, first in glass bottles, then in steel and, later, aluminum cans. Early plastic bottles showed promise as a lightweight alternative, but they leached chemicals and failed to contain carbonated drinks. If the bottle didn’t explode, the carbonation fizzled. It wasn’t until the 1970s when a miracle plastic known as PET came along and changed the game.
Polyethylene terephthalate has been around since 1941. Du Pont chemists developed it while experimenting with polymers to make textiles. In 1973 Nathaniel Wyeth, another Du Pont scientist, patented the first PET bottle. It was lightweight, safe, cheap—and recyclable. In other words, it was the perfect container to set the stage for the bottle binge that followed.
Perrier and Evian crossed the Atlantic at around that time, launching the bottled water craze. PepsiCo finally joined the water business and introduced Aquafina in 1994. Coke followed with Dansani in 1999. Both brands use refiltered tap water. Between 1994 and 2017, water sales in the United States had grown by 284 percent, according to Beverage Marketing Corp. data published by the Wall Street Journal.
Between 1960 and 1970, the average person bought between 200 and 250 packaged drinks ever year, Elizabeth Royte reported in her book Bottlemania,citing data from the Container Recycling Institute. Most of those purchases, she added, involved refillable bottles. As of 2017, on a global scale a million plastic beverage bottles were purchased every minute, according to data from Euromonitor International’s global packaging trends report, published in 2017 by The Guardian. Today, plastic bottles and jars represent about 75 percent of all plastic containers, by weight, in the United States, according to the Plastics Industry Association.
Ramani Narayan, a chemical engineering professor at Michigan State University, cautions that to focus entirely on the numbers and overuse of plastic bottles is to miss the essence of the problem.
“There is an overuse of plastic bottles that needs to be curtailed,” he says. “But the problem is misuse of bottles at the end of their life. The issue is recovery of the product and incentives to recycle, and the commitment on the part of regulators, as well as brand owners, to only use bottles that contain at least 50 percent recycled plastic. Or 60 percent. They are not making that commitment.”
New life for bottles
As the public’s focus on the plastic waste crisis narrows, the world is awash with solutions for bottles. Generally, they fall into two categories: efforts to reduce the use of plastic bottles and efforts to find new ways to deal with bottles once they’re thrown away.
Just in London, efforts to reduce plastic bottles abound. Mayor Sadiq Khan announced plans to build 100 new fountains for refillable bottles. Last spring, runners in the London Marathon were handed edible seaweed pouches at mile 23 containing a sports drink to slake their thirst. And Selfridges, London’s century-old department store, has vanquished plastic beverage bottles from its food court in favor of glass bottles, aluminum cans, and refilling stations.
Once bottles have become trash, entrepreneurs around the world are turning them into printer ink cartridges, fence posts, roofing tiles, carpets, flooring, and boats, to name only a few items. Even houses have been constructed from bottles. The latest is a three-story modern on the banks of the Meteghan River in Nova Scotia, promoted as able to withstand a Category 5 hurricane. It only took 612,000 bottles.
In laboratories, new versions of bottles claiming to be biodegradable or compostable appear regularly, and plastic industry chemists are experimenting with “chemical recycling” that returns the polymers to their constituent monomers, enabling them to be remade multiple times into new plastic bottles.
Many of the solutions are not scalable to a level that would make a noticeable difference, and most of them—including biodegradables—still require that the most elemental and least functional part of the bottle’s lifespan be performed: Someone needs to pick them all up.
Recycling rates remain low. In 2016 fewer than half the bottles bought worldwide were collected. In the United States, new PET bottles contain only 7 percent recycled content, said Susan Collins, executive director of the Container Recycling Institute. Although consumers of soft drinks dutifully returned glass bottles and collected the refund in the decades before PET was invented, beverage companies have long strongly promoted recycling, and vigorously opposed bottle deposit legislation, arguing bottle bills cost them too much money.
Beverage companies have pledged to use more recycled bottles in manufacturing, a goal that aims to reduce the production of new resin and boosts recycling numbers by adding value to bottle recovery.
PepsiCo pledged to increase recycled content in all its plastic packaging 25 percent by 2025. Nestle Waters vowed to make all of its packaging recyclable by 2025 and increase recycled content in bottles to 35 percent by 2025 globally and to 50 percent in the United States, focusing on Poland Spring. Additionally, recycled content for European brands will increase to 50 percent by 2025.
Coca-Cola pledged to recycle a used bottle or can for every one the company sells by 2030 and increase recycled material in plastic bottles to 50 percent by 2030.
