Disposable e-cigarettes a new environmental dilemma

With the growing popularity of disposable e-cigarettes, waste management systems are confronting a new vaping problem: how to safely get rid of millions of small, battery-powered devices that are considered hazardous waste.

For years, the debate surrounding vaping largely centred on its risks for high school and middle school students enticed by flavours like gummy bear, lemonade and watermelon.

But the recent shift toward e-cigarettes that can’t be refilled has created a new environmental dilemma. The devices, which contain nicotine, lithium and other metals, cannot be reused or recycled.

Globally, teens and adults are buying millions of disposable vapes per month. With little official guidance, countries are finding their own ways to dispose of e-cigarettes collected from schools, colleges, vape shops and other sites.

“We are in a really weird regulatory place where there is no legal place to put these and yet we know, every year, tens of millions of disposables are thrown in the trash,” said Yogi Hale Hendlin, a health and environmental researcher at the University of California, San Francisco in the United States.

In late August, sanitation workers in Monroe County, New York, packed more than 5,500 brightly coloured e-cigarettes into 55-gallon steel drums for transport. Their destination? A giant, industrial waste incinerator in northern Arkansas, where they would be melted down.

Sending 350 pounds of vapes across the country to be burned into ash may not sound environmentally friendly. But local officials say it’s the only way to keep the nicotine-filled devices out of sewers, waterways and landfills, where their lithium batteries can catch fire.

“These are very insidious devices,” said Michael Garland, who directs the county’s environmental services. “They’re a fire risk and they’re certainly an environmental contaminant if not managed properly.”

Elsewhere, the disposal process has become both costly and complicated. In New York City, for example, officials are seizing hundreds of thousands of banned vapes from local stores and spending more than US$1 each for disposal.

HAZARDOUS WASTE

Vaping critics say the industry has skirted responsibility for the environmental impact of its products, while regulators have failed to force changes that could make vaping components easier to recycle or less wasteful.

Among the possible changes: standards requiring that e-cigarettes be reusable or forcing manufacturers to fund collection and recycling programs. New York, California and several other US states have so-called extended product responsibility laws for computers and other electronics. But those laws don’t cover vaping products and there are no comparable federal requirements for any industry.

Environmental Protection Agency rules for hazardous waste don’t apply to households, meaning it’s legal for Americans to throw e-cigarettes in the garbage at home. But most businesses, schools and government facilities are subject to EPA standards in how they handle harmful chemicals like nicotine, which the EPA considers an “acute hazardous waste,” because it can be poisonous at high levels.

In the United States, the push to manage disposable e-cigarettes has chiefly come from schools, which can face stricter regulation if they generate more than a few pounds of hazardous waste per month. For example, Monroe County schools pay US$60 to dispose of each one-gallon container of vapes. More than two thirds of the e-cigarettes collected by the county come from schools.

“Our schools were very relieved because they had confiscated so much of this material,” Garland said. “If you think of all the high schools across the country, they are in a very difficult place right now.”

The lithium in e-cigarette batteries is the same highly sought metal used to power electric vehicles and cellphones. But the quantities used in vaping devices are too small to warrant salvage. And nearly all disposable e-cigarette batteries are soldered into the device, making it impractical to separate them for recycling.

Disposable e-cigarettes currently account for about 53 per cent of the multi-billion US vaping market, according to US government figures, more than doubling since 2020.

Their rise is a study in unintended consequences.

In early 2020, the Food and Drug Administration banned nearly all flavours from reusable e-cigarettes like Juul, the cartridge-based device blamed for sparking a nationwide surge in underage vaping. But the policy didn’t apply to disposables, opening the door to thousands of new varieties of fruit- and candy-flavoured vapes, almost all manufactured in China.

In recent months the FDA has begun trying to block imports of several leading disposable brands, including Elf Bar and Esco Bar. Regulators consider them illegal, but they have been unable to stop their entry to the United States and the devices are now ubiquitous in convenience stores, gas stations and other shops.

FDA’s tobacco chief, Brian King, said in a statement that his agency “will continue to carefully consider the potential environmental impacts” of vaping products.

THE COST OF CONFISCATING DISPOSABLE E-CIGARETTES

In 2020, New York City outlawed the vast majority of e-cigarette types, banning flavours that can appeal to youngsters.

City employees conduct thousands of inspections annually, and last year issued more than 2,400 citations to corner stores and bodegas selling illegal flavoured products.

Adding to the challenge are THC vapes sold at hundreds of unlicensed marijuana shops, a separate but related problem that has mushroomed since New York’s legalisation of recreational pot.

Since last November, officials have seized more than 449,000 vape units, according to city figures. New York City is spending about US$1,400 to destroy each container of 1,200 confiscated vapes, but many more remain in city storage lockers.

“I don’t think anyone ever considered the volume of these in our community,” said New York Sheriff Anthony Miranda, who leads a task force on the issue. “There’s a tremendous amount of resources going into this effort.”

A recent lawsuit against four large vaping distributors aims to recoup some of the city’s costs.

For now, New Yorkers who vape can bring their used e-cigarettes to city-sponsored waste-collection events.

Ultimately those vapes meet a familiar fate: They are shipped to Gum Springs, Arkansas, to be incinerated by Veolia, an international waste management firm. The company has incinerated more than 1.6 million pounds of vaping waste in recent years, mostly unsold inventory or discontinued products.

Veolia executives say burning e-cigarettes’ lithium batteries can damage their incinerators.

“Ideally we don’t want to incinerate them because it has to be done very, very slowly. But if have to, we will,” said Bob Cappadona, who leads the company’s environmental services division.

Veolia also handles e-cigarettes from Boulder County, Colorado, one of the only US jurisdictions that actively tries to recycle e-cigarette batteries and components.

Historically, Boulder has had one of the highest teen vaping rates in the country, peaking at nearly 33 per cent in 2017.

“It was like someone flicked the switch. Suddenly e-cigarettes were everywhere,” said Daniel Ryan, principal of Centaurus High School.

Beginning in 2019, county officials began distributing bins to schools for confiscated or discarded e-cigarettes. Last year, they collected 3,500.

County staffers sort the devices by type, separating those with removable batteries for recycling. Disposables are packed and shipped to Veolia’s incinerator. Shelly Fuller, who directs the programme, says managing vape waste has gotten more costly and labour intensive with the shift to disposables.
