Covid Trash Isn’t Always Dangerous. Not Everyone Got the Memo.

Overblown fears that the coronavirus could be transmitted through surfaces have created a stigma around handling nonhazardous trash, experts say. Some recyclable waste has been junked or burned.,

Across Brazil, recycling plants stopped running for months. In Uganda, a junkyard is short on reusable plastics. And in Indonesia’s capital, disposable gloves and face shields are piling up at a river mouth.

Surging consumption of plastics and packaging during the pandemic has produced mountains of waste. But because fears of Covid-19 have led to work stoppages at recycling facilities, some reusable material has been junked or burned instead.

At the same time, high volumes of personal protective equipment have been misclassified as hazardous, solid waste experts say. That material often isn’t allowed into the normal trash, so a lot of it is dumped in burn pits or as litter.

Experts say a problem in both cases is that an early fear — that the coronavirus could spread easily through surfaces — has created a hard-to-shake stigma around handling perfectly safe trash. Many scientists and government agencies have since found that the fear of surface transmission was wildly overblown. But old habits die hard, especially in countries where waste-disposal guidelines haven’t been updated and officials are still preoccupied with fighting fresh outbreaks.

“Because there isn’t a route of transmission through recycling, say, we are still finding things being burned rather than recycled because people are scared” of surface transmission, said Anne Woolridge, who leads a working group on health care waste for the International Solid Waste Association. “You try to educate the entire world’s population in less than a year. It’s impossible.”

As for personal protective equipment, Dr. Woolridge said, the sight of gloves and masks littering the world would have been unthinkable before the pandemic. “But because everybody’s saying anything to do with the pandemic is a medical waste, it’s put pressure on the system,” she added.

Recycling shutdowns

Recycling rates dropped sharply around the world last year, in part because demand from manufacturers fell. In many countries where the recycling industry is still driven by hand sorting, rather than machines, in-person work was suspended out of virus-related fears.

In Brazil, for example, the generation of recyclable material in cities rose 25 percent in 2020, primarily because of a spike in online shopping, according to Abrelpe, a national association of sanitation companies. But recycling programs in several cities suspended operations for several months anyway, citing fears of surface transmission.

That had clear human and environmental costs. A recent study found that during the suspension period, at least 16,000 fewer tons of recyclable material than usual were in circulation, representing an economic loss of about $1.2 million per month for waste-picker associations. Another study said a month of suspensions was a missed opportunity to save the amount of electricity used by more than 152,000 households.

“The suspension highlighted our system’s weaknesses,” said Liane Nakada, a co-author of the second paper and a researcher at the University of Campinas. She and her husband stored their recycling at home for months to avoid discarding it improperly, but they were the exception.

A global divide

Recycling rates are now inching back to pre-Covid levels in developed economies, said James D. Michelsen, a solid waste expert at the International Finance Corporation.

“The numbers are getting back to normal and we’re pivoting away from a Covid discussion to one of ‘OK, let’s get back to circularity, sustainability, plastics recycling,'” Mr. Michelsen said.

But in countries where recycling is driven by informal collectors, he added, lockdowns and outbreaks are still creating major disruptions.

Before a recent Covid outbreak hit Kampala, Uganda, hundreds of people would gather to pick through plastics at a city dump. They would then sell the plastics to middlemen, who later sold it to recycling companies.

But when the country went into a lockdown this summer, restrictions on movement prevented trucks from picking up trash in some districts. There were also fears of surface transmission: Officials said Covid was surging because people hadn’t been washing their hands.

As of this month, only about a third of the usual number of waste pickers were at the Kampala city dump, said Luke Mugerwa, a representative for a local pickers’ group. Some manufacturers who came looking for recovered plastics were out of luck.

“Every day, they are always looking for plastics to buy,” Mr. Mugerwa said. “The demand is there but the supply is very low.”

Proliferating P.P.E.

Another challenge is the used personal protective equipment that has flooded the world since the early days of the pandemic. About eight million metric tons of plastics already enter the ocean every year, and experts fear that used P.P.E. and other litter could make that situation even worse.

Most P.P.E. is not hazardous, but many countries still classify it as such, said Mr. Michelsen of the International Finance Corporation. That means used gloves and masks are often lumped together with truly hazardous medical waste and either treated at great expense — a waste of money — or disposed of through other means.

Understand Vaccine and Mask Mandates in the U.S.

Vaccine rules. On Aug. 23, the Food and Drug Administration granted full approval to Pfizer-BioNTech’s coronavirus vaccine for people 16 and up, paving the way for an increase in mandates in both the public and private sectors. Private companies have been increasingly mandating vaccines for employees. Such mandates are legally allowed and have been upheld in court challenges.Mask rules. The Centers for Disease Control and Prevention in July recommended that all Americans, regardless of vaccination status, wear masks in indoor public places within areas experiencing outbreaks, a reversal of the guidance it offered in May. See where the C.D.C. guidance would apply, and where states have instituted their own mask policies. The battle over masks has become contentious in some states, with some local leaders defying state bans.College and universities. More than 400 colleges and universities are requiring students to be vaccinated against Covid-19. Almost all are in states that voted for President Biden.Schools. Both California and New York City have introduced vaccine mandates for education staff. A survey released in August found that many American parents of school-age children are opposed to mandated vaccines for students, but were more supportive of mask mandates for students, teachers and staff members who do not have their shots. Hospitals and medical centers. Many hospitals and major health systems are requiring employees to get a Covid-19 vaccine, citing rising caseloads fueled by the Delta variant and stubbornly low vaccination rates in their communities, even within their work force.New York City. Proof of vaccination is required of workers and customers for indoor dining, gyms, performances and other indoor situations, although enforcement does not begin until Sept. 13. Teachers and other education workers in the city’s vast school system will need to have at least one vaccine dose by Sept. 27, without the option of weekly testing. City hospital workers must also get a vaccine or be subjected to weekly testing. Similar rules are in place for New York State employees.At the federal level. The Pentagon announced that it would seek to make coronavirus vaccinations mandatory for the country’s 1.3 million active-duty troops “no later” than the middle of September. President Biden announced that all civilian federal employees would have to be vaccinated against the coronavirus or submit to regular testing, social distancing, mask requirements and restrictions on most travel.

“If you have high volumes coming out the back of your hospitals in these areas that don’t have infrastructure, they’re just going to set fire to it,” Dr. Woolridge said.

The United Nations Environment Program estimated last year that health care facilities around the world were producing about 7.5 pounds of Covid-related medical waste per person per day worldwide. It said that in Jakarta, Indonesia, and four other Asian megacities, the rate of overall health care waste disposal had risen by about 500 percent.

Some of that waste inevitably ends up as litter. In the Indonesian capital, prepandemic pollution surveys of a local river mouth by the Research Center for Oceanography did not turn up much P.P.E. But a recent survey found that equipment like masks, face shields, gloves and hazmat suits accounted for about 15 percent of the pollution.

“Even in Jakarta, which has the country’s biggest budget for environmental management, the waste is still leaking into the environment,” said Muhammad Reza Cordova, a scientist involved in the river surveys. “What about other areas with smaller budgets?”

A hunt for syringes

An emerging concern is that, as the flood of material creates new pressures on local authorities, syringes and other truly hazardous medical waste may end up in the wrong places.

In the world’s poorest countries, that would pose a health risk to waste pickers. Tens of thousands of people already scavenge in landfills in Bangladesh, for example. But only three or four of the country’s 64 districts have facilities to safely dispose of used syringes, said Mostafizur Rahman, a solid waste expert in the capital, Dhaka.

“These landfills are not secure or sanitary, so it’s really concerning in terms of environmental health and safeguards,” said Dr. Rahman, a professor of environmental sciences at Jahangirnagar University.

And because syringes and vaccine vials are a valuable commodity on the black market, criminal gangs have an incentive to steal vaccination gear and illegally resell it into the health care system.

Late last year, Interpol warned that the pandemic had already “triggered unprecedented opportunistic and predatory criminal behavior” around the theft, falsification and illegal advertising of Covid-19 and flu vaccines. The warning came before most of the world’s population had even received a Covid shot.

“It’s a real issue in the marketplace,” Mr. Michelsen said. “These vials have a huge black market value because you can fill them with whatever you want and sell them.”
