Five Myths About Recycling
From the kitchen table to the editorial pages, people have
been debating the merits of recycling for decades. Does it really save energy
and money? Can I recycle that yogurt cup or juice box? At the same time,
recycling technology and global markets have evolved quickly, leaving some
consumers confused or stuck in old, outdated ways. A lot of myths persist about
those blue bins. Here are some of the most common.
Myth No. 1: Recycling uses more energy than making something new.
This myth has been
kicking around for decades. Daniel K. Benjamin, a senior fellow at the Property
and Environment Research Center, recently told Big Think, "In most cities
across the nation, recycling of household trash is, in fact, wasteful, even
when we take into account the meager environmental benefits of such
recycling." And as Leland Teschler of Machine Design put it, "Save
energy: Don't recycle."
But according to the
Environmental Protection Agency, recycling aluminum cans saves 95 percent of
the energy needed to make new ones from raw materials. Recycling steel and tin
cans saves 60 to 74 percent, recycling paper saves about 60 percent,and
recycling plastic and glass saves about one-third of the energy compared with
making those products from virgin materials. The energy saved from recycling
one glass bottle will operate a 100-watt light bulb for four hours.
During the historic
California drought a few years ago, some people asked if they should stop
recycling in order to save water. Yet an analysis by the website Treehugger
confirmed that more water is saved by processing recycled materials than by
making new stuff.
Myth No. 2: Items must be meticulously sorted for recycling.
When recycling was a
relatively novel concept, many waste haulers insisted on strict sorting rules.
As collection and recycling machinery evolved, many of those rules changed.
Confusion abounds: Can I recycle an envelope with a plastic window? Do I have
to remove staples from paper? In my Washington apartment building, neighbors
have posted conflicting signs about whether glass must be sorted by color or if
plastic bags are accepted.
In general, people
don't need to sort their recyclables to anywhere near the degree they used to.
More communities are now using "single stream" systems, in which
people are encouraged to place all their recyclables into one container.
Cleaner materials reduce odors and speed the process, but the recycling steps
involve washing, shredding and crushing the material, and then often melting
it. Food residue and impurities like paper clips are burned off or collected
through magnets and other means. Items made from multiple types of materials,
like juice cartons, can be more difficult to recycle, but each facility handles
such materials based on its own equipment and needs. Right now, more than 60
percent of U.S. households have access to carton recycling, and product
manufacturers have been working on making packaging that is easier to recycle.
Myth No. 3: Products made from recycled content are lower quality.
A few decades ago,
products made from recycled materials were often derided as subpar. Recycled
paper was gray and rough. Recycled plastic had a reputation as weak. Some
people still associate recycled content with lower performance. "Recycled
materials are often of lower quality than the materials from which they were
derived," Alexander Hellemans wrote for youris.com. And in one survey,
consumers said they were less likely to buy environmentally green products
because they assumed them to be inferior.
But manufacturers
have learned a great deal since the early days, and consumer and corporate
demand for recycled products has risen so steadily that producers have made
considerable strides in quality. "As more and more companies publish their
sustainability goals, the use of recycled resins is transitioning from just a
low-cost alternative to a specified part of many new products," Ron
Whaley, CEO of Geo-Tech Polymers, an Ohio recycler, told Plastics Technology.
". . . Products must now meet the same high quality and performance
characteristics as virgin resin."
Numerous studies have
shown that paper with recycled content now meets high performance standards.
Glass, plastic and metal containers with recycled content have been approved
for use with food products by the Food and Drug Administration.
Myth No. 4: Recyclables just end up in the trash.
It's become something
of an urban legend: the garbage man who dumps all the carefully separated
recyclables in with the trash. Sightings of this rogue figure abound online.
"Today I just watched my trash/recycling company dump my three weeks'
worth of recycling into the same truck as my trash. Just like that," wrote
one self-described "indignant" recycler. At least one local news station
has gotten in on the act: "Recycling getting dumped in the trash?"
asked Palm Springs, California, CBS affiliate KESQ. "See what one Palm
Desert resident caught on camera." And on a scale far beyond the local
garbage truck, some material marked for recycling has landed in the trash: In
2013, China's crackdown on imports of "low-quality" scrap materials
caused some U.S. recyclers to divert some of their collected plastics to
landfills.
Since then, though,
the domestic recycling industry has shown signs of maturing. Nina Belluci
Butler, CEO of research and consulting firm More Recycling, says markets have
been relatively stable for plastic bottles, which means fewer recyclables
headed for the landfill.
The fear that
everything we painstakingly sort will just end up in the same place as the rest
of our garbage is overblown, experts caution. Patty Moore, who co-founded More
Recycling, told Business Insider that "there are buyers for [recyclables]
all day long. The amount that's going to the landfill is insignificant."
Contamination of collected recyclables can decrease their value and increase
the amount that must be discarded - across the U.S., about 25 percent of items
placed in blue bins can't be recycled at their end point - but the solution is
better consumer awareness, not abandonment of programs. As Patrick Carter,
executive director of the Sonoma County, California, Waste Management Agency,
told the North Bay Business Journal, "Garbage companies find
markets," despite fluctuating prices and bumps in the road. As for the
worry that rogue garbage collectors are simply tossing our carefully sorted
materials into the dust heap, there's just not much evidence of it happening on
a large scale.
Myth No. 5: Recycling should pay for itself.
The idea that
municipalities should make money, or at least break even, on recycling programs
is a popular talking point. As one Washington Post editorial put it:
"Recycling pays for itself. Indeed, we can't afford not to recycle."
Bucknell University economist Thomas Kinnaman took a close look at recycling in
Japan and concluded that an "optimal" recycling rate, which would
derive what he defined as the most benefit from the lowest cost, would be about
10 percent of all materials. Recycling plastic and glass didn't make the cut in
his analysis, because of the relatively low costs for the virgin materials and
sorting and shipping challenges.
But cities can't
control world markets. Recycled materials are economic commodities, just like
pork bellies and microchips, and their value rises and falls. When oil prices
are low, it's cheaper to make plastics from virgin materials (i.e., petroleum
products). Buyers for recycled materials aren't evenly distributed across the
country, and their demand changes with other market forces. In part because of
these pressures, Waste Management - the country's largest waste hauler -
shuttered 20 recycling facilities in 2014 and 2015.
While many
jurisdictions find that they can make money off a recycling program, some
places struggle. A state-of-the-art recycling facility in Alabama was forced to
shutter less than two years after its grand launch after global commodity
prices tanked.
A number of
entrepreneurs are working on new business models to increase participation in
recycling and make it more profitable for cities.Recyclebank rewards consumers
who recycle with various incentives. Vending machines in Australia offer people
a small prize, like a food truck coupon, for depositing recyclables.
Recycling can be a
messy business, and sometimes it's a net loss for a jurisdiction. But the
long-term economics remain relatively sound, especially since prices for oil
and other raw materials are expected to climb. And recycling creates jobs -
some 1.25 million in the United States.
Beyond short-term
dollars and cents, it's clear that recycling provides numerous benefits to the
environment and society. There's much to be gained by asking people to be more
conscientious about their waste.
