What Happens to Old Golf Balls?

Ever wonder what actually happens to the golf ball you just sliced into the lake or lost deep in the woods? It doesn’t just vanish. That small white sphere embarks on a surprisingly complex journey that can see it end up back in a golfer's bag, repurposed into flooring, or sitting at the bottom of a pond for decades. This guide explains the entire life cycle of a lost ball, from the moment it leaves your clubface to its ultimate fate, and gives you a coach's perspective on whether you should be playing with them.

So, You've Lost a Golf Ball. Where Does It Go?

According to some estimates, golfers lose hundreds of millions of balls every year. They fly into water hazards, vanish into thick rough, get buried under fallen leaves in the woods, or simply get plugged in soft turf, hidden from view. The most common hiding spots are, without a doubt, ponds and creeks.

Once lost, a golf ball enters a state of suspended animation. Unlike organic materials, its multi-layer construction of synthetic rubber and plastic polymers like urethane or ionomer means it won't biodegrade for a very, very long time - potentially hundreds of years. It Curls up against the mud at the bottom of a pond, nestled among others of its kind, waiting. For a golfer, it's a lost investment and a frustrating penalty stroke. For the environment, it's a piece of non-decomposing plastic. But for a specific group of entrepreneurs, it’s a potential treasure.

The Surprising Second Life of a Lost Ball

The journey from a water hazard back to the golf course is a true tale of recycling and reclamation, driven by a thriving industry built entirely on our mishits.

The Treasure Hunters: Golf Ball Divers

The heroes of this story are the golf ball divers. These are professionals, often local entrepreneurs or small companies, who contract with golf courses to retrieve the massive number of balls submerged in their water hazards. Outfitted with scuba gear, large mesh bags, and sometimes even custom-built dredging equipment, these divers can pull thousands of balls out of a single pond in just a few hours.

They work systematically, combing the murky bottoms of ponds where golfers’ tee shots most often land. The sheer volume can be staggering. A well-placed hazard on a busy an amateur-friendly course can yield tens of thousands of balls annually. Once collected, these balls are hauled off-site for the next stage of their journey: cleaning and sorting.

The Sorting and Grading Process

Once retrieved, the balls aren't just rinsed and thrown into a carton. They undergo a rigorous process to bring them back to a playable, sellable condition.

1. The Wash: The first step is a thorough cleaning. Balls are tumbled in industrial washing machines with special solutions to remove algae, mud, and stains without damaging the cover.
2. The Inspection:After they are sparkling clean, every single ball is inspected manually. Workers sort them based on brand, model, and, most importantly, condition.
3. The Grading: This is a critically important part of the business. Balls are categorized into different grades, which tells you, the consumer, the quality of the used ball you are buying. While the terminology varies slightly between sellers, the grades generally follow this system:
   • A-Grade Balls (also known as Mint or AAAAA): These balls are the closest you can get to new. They may have a player's marker pen mark or a tiny corporate logo, but they have no scuffs, scratches, or blemishes. They look and feel like they’ve been hit maybe once or twice.
   • B-Grade Balls (also known as Near Mint or AAAA): These balls are still in excellent condition but have minor signs of previous play. You might find a very small scuff or slight discoloration. Performance is virtually identical to a new ball.
   • Practice Grade/Standard (also known as Good or AAA): These are the workhorse balls. They will have visible scuffs, blemishes, or discoloration and may be older models. They're perfect for casual rounds, practice, or for players who tend to lose a few balls and don’t want to break the bank. You should not play competitively with Grade C onwards because the aerodynamics of the ball could be impacted.

After being graded, they're packaged and sold online, to driving ranges, or back to retail and pro shops at a fraction of the cost of new balls. It’s a sustainable model that benefits the golf course (which gets a cut of the revenue), the environment (by removing plastic from waterways), and golfers' wallets.

Does an Old or Refurbished Ball Perform Differently? A Coach's View

This is the question I get most often from students: "Is it okay to play with a used golf ball?" The answer depends on two things: the condition of the ball and your goals as a golfer.

The Impact of Water and Age

The integrity of a golf ball can be compromised by prolonged exposure to the elements, especially water. Here's a simple breakdown:

A golf ball isn’t a solid, impenetrable sphere. It’s made of layers. While the outer cover (urethane or ionomer) is highly water-resistant, it's not completely waterproof. Over weeks, months, or years spent submerged, moisture can slowly penetrate into the inner core. When the core absorbs even a small amount of water, it loses its "energetic material" and its ability to compress and rebound effectively at impact.

The result? A waterlogged ball will fly shorter and have a less consistent flight. A study by an independent testing company found that balls submerged in water for just a week could lose 5-6 yards on a driver shot. After three months, that loss could increase to over 10 yards. The performance loss is subtle but measurable.

This is why the grading process is so essential. A "Mint" A-grade ball was likely a ball lost recently (hit into the rough, found the next day). It has seen almost no elemental exposure and its performance is identical to new. A ball pulled from the slimy bottom of a pond after two years, even if it looks cosmetically clean, could be a compromised "dud."

Who Should Use Recycled Balls?

• For Competitive &, Low-Handicap Golfers: If you are playing in a tournament or are a dedicated player trying to shoot your lowest scores, stick with new balls or only the highest quality A/Mint grade recycled balls. At your level, a 5-yard difference in carry or an inconsistent flight can be the difference between a birdie putt and a tough up-and-down.
• For Most Amateur Golfers (Mid-to-High Handicappers): B-Grade and even Practice-grade balls represent fantastic value. Let's be honest: for most golfers, the small potential distance loss is negligible compared to the inconsistencies in our own swings. Saving $20-$30 on a box of balls means you can afford another green fee. Using recycled balls takes the sting out of losing one and allows you to play with less fear, which almost always leads to better, more relaxed golf.

Beyond the Course: The End of the Road for a Golf Ball

What happens to a golf ball that is too scuffed, cracked, or water-damaged to be resold as a playable ball? Its journey isn’t necessarily over.

These reject balls often find their way into a few final resting places:

• Driving Ranges: Many ranges buy bulk quantities of low-grade used balls for practice sessions.
• Donations: Organizations like The First Tee, junior golf programs, and high school teams are often happy to receive donations of any playable balls for their students.
• Industrial and Creative Recycling: This is a growing field. Because of their complex, layered materials, golf balls are difficult to recycle traditionally. However, some specialized companies have developed processes to grind them down. The resulting composite material of rubber and plastic can be used to create new products, such as athletic court surfacing, playground flooring, decorative mulch, and other construction materials. Some are even sliced up and used in creative applications ranging from art to massage tools... but this happens to only a very small fraction of retired golf balls
• The Landfill: Unfortunately, this is the final resting place for many used golf balls that don't find a second use. It underscores the importance of the retrieval and recycling industry in keeping as many of these non-biodegradable objects out of the environment as possible

What Should You Do With Your Old Golf Balls?

If you have a growing shag bag of old, tired golf balls rattling around in your garage, here’s how you can be a part of the solution:

• Practice Balls: Designate your most scuffed-up balls for chipping and pitching practice in the yard or at a practice green.
• Water Hazard Balls: Keep a few oldies in a separate pouch for those high-risk, high-reward shots over a lake. It'll hurt less when you lose a ball you already retired.
• Donate: Your local junior golf program or high school team would likely be thrilled to take playable balls off your hands.
• Check with your Pro Shop: Many courses or retailers have programs where they accept old balls, sometimes offering store credit in return, which they will then send off to be professionally refurbished.

Final Thoughts

The story of what happens to old golf balls is a cycle of loss, recovery, and rebirth that keeps billions of them in play and out of landfills. From dedicated divers to golfers seeking value, this hidden industry ensures that a bad shot doesn’t have to mean the end of the road for the ball itself.
