NEW YORK (AP) — Tennis has a fuzzy yellow drawback most gamers don’t take into consideration once they open can after can of recent balls, or when umpires at U.S. Open matches make their frequent requests for “new balls please.”
Because tennis balls are extraordinarily onerous to recycle and the business has but to develop a ball to make that simpler, practically all the 330 million balls made worldwide annually ultimately get chucked within the rubbish, with most ending up in landfills, the place they will take greater than 400 years to decompose. It’s a state of affairs highlighted by Grand Slam occasions like Flushing Meadows, which can undergo practically 100,000 balls over the course of the match.
That harsh actuality in an age of heightened environmental consciousness has despatched ball makers, recyclers and the sport’s worldwide governing physique scrambling for options, and spurred sustainability activists to sound the alarm in on-line posts that pose the query: Are tennis balls a catastrophe for the planet?
“Tennis balls, like a lot of objects, are made to be indestructible, which means they’re very resistant to mechanical processing,” mentioned Nickolas J. Themelis, director of Columbia University’s Earth Engineering Center. “But do you take a useful object that lasts forever and say people shouldn’t use it because it lasts forever? That’s nonsense.”
Themelis and different consultants be aware that tennis balls make up a tiny fraction of the a whole lot of tens of millions of tons of rubbish produced yearly, and the keys with all difficult-to-recycle supplies are discovering methods to increase their helpful life by way of different functions and taking care of their final disposal to maintain them out of the surroundings.
“Anyone who would say you shouldn’t play tennis because of the tennis balls is misinformed,” mentioned Jason Quinn, director of Colorado State University’s Sustainability Research Laboratory. “In terms of the impact, it’s a blip on the radar. … And there are things you can do to reuse and repurpose tennis balls to lessen the impact.”
Among them are efforts by nonprofits and others to transcend simply utilizing outdated balls for canine toys and the underside of chairs. That contains gathering balls in bulk and grinding them down into materials that’s used to make merchandise together with the footing for horse arenas and – in a little bit of excellent symmetry – tennis courts.
But consultants and environmentalists query whether or not these initiatives are viable sufficient to make a dent, and so they say such efforts don’t deal with the underlying drawback of a scarcity of a totally recyclable tennis ball, or the elements that make balls significantly troublesome.
At the highest of the checklist is the tennis ball design – considerably unchanged for the reason that creation of pressurized balls within the Nineteen Twenties – consisting of a felt masking glued to a hole, air-filled rubber core.
The largest barrier to recycling the rubber within the ball is the problem of eradicating the felt from the rubber core due to the tight glue designed to carry that cowl on when it’s thwacked by a racket. And the felt can be an issue: a blended mixture of wool and nylon that can not be recycled.
What’s extra, the core of most top-level tennis balls — such because the Wilson U.S. Open extra-duty mannequin in play at Flushing Meadows – is barely comprised of newly created, virgin rubber, which activists say results in deforestation of rubber timber within the Amazon.
“It is true that virgin rubber is used because of the performance specifications required for the best in the world,” mentioned Jason Collins, common supervisor of world racquet sports for Wilson Sporting Goods. “Other tennis balls within our product line absolutely can and do include recycled rubber.”
Another situation carbon-footprint-wise are the locations most balls are made — Thailand and China — as a result of these balls must be shipped hundreds of miles to achieve North America and Europe, the place a lot of the world’s tennis is performed.
Seeking to sort out these issues is the International Tennis Federation, which certifies tennis balls and sanctions competitions world wide. It launched a technical working group final yr made up of producers, officers from different tennis governing our bodies and recyclers with an formidable set of objectives:
Is there a approach to design a totally recyclable ball? What are the capabilities of balls on completely different ranges of play? Can the ITF, utilizing its rule-making muscle, maintain balls in play longer in competitions, which might lead to fewer balls used? Do Grand Slam occasions have to stay with changing balls after the primary seven video games and each 9 video games thereafter? Could that be prolonged to 11 or 13 video games? And might such adjustments to make use of fewer balls longer filter all the way down to all gamers?
“We want to try and identify ways of making the consumption pattern more sustainable and the product more sustainable as well,” mentioned Jamie Capel-Davies, the ITF’s technical head who works out of the federation’s lab in London.
“The overall strategy is to use the waste hierarchy,” Davies mentioned. “First of all, to try and reduce the number of balls that are being used. Then reuse balls as best we can. Recycling is third. And then disposing of balls is right at the bottom, the least desirable.”
Among the constructive indicators getting scrutiny: Efforts to repressurize “flat” balls in bulk to convey them again to life, an answer that doesn’t deal with worn-down felt. A Dutch firm’s improvement of a ball comprised of 30% outdated tennis balls (any extra would apparently lower into playability). And Wilson’s introduction of its Triniti ball, a still-pressurized mannequin that has a sturdier core that leaks much less and a harder felt designed for use for a minimum of 4 outings with out dropping bounce or fuzz.
“While there is not a fully recyclable tennis ball that meets the performance specifications of elite athletes yet, we are proactively innovating for the future,” mentioned Wilson’s Collins.
A constructive on the recycling entrance are nonprofits taking over the duty of gathering and repurposing tennis balls, most notably Vermont-based RecycleBalls, which says it’s on tempo to gather 3 million tennis balls this yr from throughout the U.S. and Canada.
ReycleBalls distributes assortment bins at a whole lot of tennis golf equipment, metropolis parks, schools and tournaments, the place used balls might be shipped post-paid to the group’s warehouse to be sorted for a wide range of makes use of.
Some are bought as canine toys or for the underside of chairs, some are floor up entire with the felt to be bought as footing for horse arenas, and nonetheless others are despatched to a extremely specialised, patent-pending machine that pulls the felt off the rubber and grinds the rubber into different-sized granules which were made right into a cushioning layer by the tennis courtroom surfacing firm Laykold.
And different attainable makes use of for the granules are being explored, resembling utilizing them in mulch, constructing supplies resembling stucco and siding, and even parts in furnishings.
“We believe in multiple lives for tennis balls,” mentioned RecycleBalls CEO Erin Cunningham, who acknowledged her group might repurpose much more balls if there have been extra corporations prepared to include the rubber into their merchandise.
“We don’t want to just collect tennis balls and have them sit in the warehouse,” Cunningham mentioned. “We need to make sure that there’s actually demand for recycled product on the back end.”
At the United States Tennis Association’s places of work below the stands of Louis Armstrong Stadium this week, a row of RecycleBalls bins lined a hallway, shortly submitting with U.S. Open balls and instantly shipped off for repurposing. Other balls from the occasion will get a second use at USTA clinics and coaching facilities throughout the nation, and nonetheless others will likely be packed individually and bought at U.S. Open present outlets for $10 every.
For the overwhelming majority of balls that aren’t so fortunate, Columbia University’s Themelis believes their last resting place shouldn’t be landfills however waste-to-energy crops that burn rubbish to generate electrical energy. More extensively utilized in Europe and China, Themelis says they deal with solely about 10% of the rubbish within the U.S., the place they’ve come below scrutiny due to considerations over emissions.
Opponents of such crops say that in relation to discovering options for hard-to-recycle gadgets resembling tennis balls, it’s higher to innovate than incinerate.
“A big part of that is summoning the will to change,” mentioned Claire Arkin, spokeswoman for Global Alliance for Incinerator Alternatives. “And that really means that the companies behind these products need to take the entire life cycle into account.”
“We’ve seen myriad examples of innovation in terms of redesign of products, and tennis balls are overdue for that kind of a makeover.”
