The Atlanta Magnet Man has a system for saving bikers from flat tires.

Multitasking Americans like to do more than one thing while exercising. Some people listen to podcasts on their walk. Some turn the elliptical toward the TV. I try to do breathing and meditaion on the treadmill.

Now, here’s a guy who picks up bike-damaging metal while exercising. Cathy Free has the story at the Washington Post.

“Alex Benigno was sick of changing his flat tires. He was getting them all the time … on his bike tires when he biked after work. ‘I’m really good at getting flat tires, and I was tired of patching them all the time,’ he said.

“He looked into it and learned that metal road litter is a nationwide problem, often caused by nails or other sharp objects spilled from trucks, and sometimes even done deliberately. In the United States, a vehicle tire is punctured every seven seconds, causing 220 million flat tires a year, according to a report by Autoily.

“Benigno decided to do something about it. … About a year ago, he bought 10 strong magnets for $160 online, attached them to the underbelly of his bike trailer, then went for a ride through Atlanta late one afternoon to see how many nails, screws, bottle caps, flattened cans and pieces of metal wire he could attract. Benigno rides a stand-up bike because of his back surgery 12 years ago.

“During his first 10-mile trip with the magnets attached, the underside of the trailer picked up about six pounds of sharp metal bits.

“ ‘From there, I decided to keep going out after work every day, added more magnets and tried all kinds of configurations with them to get to where I was collecting even more,’ he said.

“He attached a broom to the trailer to help sweep more metal into the magnets, and he selected different areas of the city to ride through each time.

“By December, he said he was picking up about 50 pounds of debris every 10 days, scraping it off the bottom of the trailer each night and storing it in bins in his car and home or at the photo supply shop where he works.

“When he started an Instagram page in January to alert people to the problem of metal debris in the streets, Benigno called himself the ‘Atlanta Magnet Man.’ His videos and posts quickly built a following, and Georgia Public Broadcasting shared the story of his street cleanup efforts.

“People immediately began to post thank you messages, sharing their own stories of flat tires.

“ ‘Midtown is the worst,’ wrote one person. ‘I have had a couple of flat tires in recent years with all the construction.’ …

“Benigno posted one of his cycling videos on YouTube last month to give people a better idea of how much debris his magnets pick up.

“When Laura Lewis, an Atlanta scrap metal artist, found out what he was doing, she offered to take the mess he’d collected off his hands.

“ ‘I gave her the whole batch — 410 pounds worth,’ Benigno said. ‘I love that she can do something with it.’

“Lewis said she’d been looking for some smaller metal pieces to add more detail to her sculptures. …

” ‘They send out street sweepers to clean the streets, but they really can’t catch all the small bits,’ Benigno said. ‘Because some of these things are so little, they’re flipped around by the sweeper, and when someone runs over them, there goes another flat tire.’ “

I love that an artist can use Benigno’s trash. It’s amazing what certain people find a use for, but you’re lucky if you find them. We once replaced a copper roof, and a copper sculptor was thrilled to get free material for her work.

Today’s post features two articles on a worrisome environmental issue. In the Guardian, Oliver Milman reports that pollution from abandoned tires is killing off salmon in the Pacific Northwest and may be harming other wildlife as well. But at the Christian Science Monitor, writer Lindsey McGinnis suggests help is on the way.

Oliver Milman: “Pollution from car tires that washes into waterways is helping cause a mass die-off of salmon on the US west coast, researchers have found.

“In recent years, scientists have realized half or more of the coho salmon, also known as silver salmon, returning to streams in Washington state were dying before spawning. The salmon, which reach 2ft in length, are born in freshwater streams before making an epic journey out to sea where they live most of their adult lives. A small number then return to their original streams to lay eggs before dying.

“The cause of the die-off has remained a mystery but a new study, published in Science, has seemingly found a culprit. When it rains, stormwater carries fragments of old car tires into nearby creeks and streams. The tires contain certain chemicals that prevent them breaking down but also prove deadly to the coho salmon. …

“Said Jenifer McIntyre, an assistant professor of aquatic toxicology at Washington State University. ‘The more we look, the more we find it. In some years all of the fish we find dead did not spawn.’

“Samples taken from urban streams around Puget Sound, near Seattle, and subsequent laboratory work identified a substance called 6PPD, which is used as a preservative for car tires, as the toxic chemical responsible for killing the salmon.”

What can be done? Lindsey McGinnis talks to a group of inventive young people in England who may have an answer.

“Every time a car brakes, accelerates, or changes direction, the friction wears down the exterior of the tire, sending particles into the environment. Some remain suspended in the air, and others get swept into local waterways, where they can have devastating effects on plant and animal life. …

“A group of master’s students from Imperial College London and the Royal College of Art had an idea: what if the tires picked up after themselves?

“The Tyre Collective, a project by recent graduates Hugo Richardson, Siobhan Anderson, Deepak Mallya, and Hanson Cheng, seeks to capture this stealthy pollutant as it flies off the wheel. For the past year, they’ve been working on a device that can attach to the bottom of a car and use electrostatic charges, along with the airflow of the moving wheel, to collect particles for reuse.  

“The inspiration came from rubbing a balloon over a sweater and seeing the pieces ‘dancing around,’ says Mr. Richardson, chief technical officer of The Tyre Collective. ‘That led us to the assumption that the particles are charged due to the friction.’ ” 

The Tyre Collective won the 2020 James Dyson Award for the UK, which celebrates the next generation of design engineers. It was a runner-up for the international version of the award.

“Gavin Whitmore, manager of the Tire Industry Project, an initiative by the World Business Council for Sustainable Development geared toward better understanding the potential health and environmental impact of tires, says his organization is keeping an eye on their work … said, ‘We’re certainly interested to learn more, because it could be a very, very promising thing.’

“Tires are more complex than they look. The vulcanized rubber compound that makes up the outermost layer, the tread, often contains sulfur, zinc, carbon black, bisphenol A (BPA), and other chemicals. A lot of that gets swept off the roads by rain, along with motor oil, bits of pavement, and other litter.

“A three-year study by the San Francisco Estuary Institute (SFEI) found that stormwater carries roughly 7 trillion microplastic pieces into the bay annually – more than 300 times the discharge from the area’s wastewater treatment plant. Nearly half of those appear to be tire fragments.

” ‘Seeing all these black rubbery particles was a surprise,’ said Rebecca Sutton, a senior scientist at SFEI. … ‘No one had really looked at stormwater. It’s also probably just a tip of the iceberg, because most tire particles are actually smaller than our sieve size.’ …

“Tires are the second-largest source of primary microplastic pollution in the ocean, after synthetic textiles, according to the International Union for Conservation of Nature and Natural Resources. To reduce the amount of tire pollution, Dr. Sutton says governments could consider setting emission standards similar to those for engine exhaust.

“But it can be hard to figure out how much material tires are actually shedding, or should be shedding. Tire wear is heavily influenced by the roadway, the weight and type of vehicle, and the driver’s behavior. In London, The Tyre Collective says a busy bus route can generate a grapefruit-size pile of tire dust in a day. …

“Says Sarah Amick, vice president of environment, health, safety, and sustainability for the U.S. Tire Manufacturers Association, ‘Tires are one of the most regulated products for safety in the United States. [Ensuring] that we can continue to meet those safety requirements, plus adding more renewable and recyclable materials to our tires, it’s a challenge, but our members are working on that.’ …

“During lockdown, the [Tyre Collective] team has focused on turning their vision into a full-fledged startup. They say several manufacturers have expressed interest in their design, though no partnership has been formalized yet. When restrictions due to COVID-19 ease, they’re looking forward to returning to the lab and producing a set of first-generation prototypes to test with potential partners.” More
