Two students had an idea at a scrapyard. They went on to "upcycle" 80,000 airbags, 100,000 seatbelts and 28,000 belt buckles – the equivalent of 60 tons of car trash
Much to their surprise, their classmates responded with so much enthusiasm to their “trash bag” concept that it convinced the two innovators to keep going. Every semester, they improved the prototype further. With the help of YouTube videos, they taught themselves how to sew. Because modern electric sewing machines had a difficult time breaking through the tough nylon of the airbags, Goosses and Widmann went to a second-hand shop and purchased an ancient Singer from 1880 for 10 Euros. They dyed the first airbags in a saucepan in the garden outside of the apartment they shared.
“By the time we graduated, we had a presentable prototype and a business plan,” Goosses says.
Despite their progress, Goosses and Widmann are up against a problem that’s immense: Cars are notoriously difficult to recycle because many parts are considered toxic waste.
It’s an example of “upcycling,” when you spot a potential new use in something that’s been trashed, shelved or otherwise retired. The approach has received increasing attention and support from the U.S. Environmental Protection Agency and others to boost sustainability in all kinds of areas, from fashion (where even luxury brands like Balenciaga or Coach repurpose vintage clothing and bags) to architecture, where reusing wood, steel and bricks significantly reduces a building’s carbon footprint.
In addition to helping the planet, those who do it well can make a living from it. These days, Goosses and Widmann own a flourishing company: Airpaq. A crowdfunding campaign in 2017 yielded 70,000 Euros to get them started. Since then, they have upcycled 80,000 airbags, 100,000 seatbelts and 28,000 belt buckles – the equivalent of 60 tons of car trash.
For the successful upcycling, they received the 2021 German Design Award and, earlier this year, the renowned German Sustainability Award. The jurors evaluating the product commented that the startup “convinced us not only because of their uncompromising quality and functionality but also because of their ecological and ethical values….How well the startup translates upcycling and green fashion into an urban lifestyle brand is impressive.”
Despite their progress, Goosses and Widmann are up against a problem that’s immense: Cars are notoriously difficult to recycle because many parts are considered toxic waste. Therefore, up to 25% of vehicle scraps get shredded every year in Germany alone, the equivalent of over 501,000 tons. Because airbags and seatbelts are nearly indestructible, they are costly to recycle and almost always end up in landfills. Given that airbags and seatbelts save lives, they are subject to stringent security regulations, and manufacturers have a sky-high reject rate. “If a tiny filament protrudes somewhere, the manufacturer will throw out the entire output,” Widmann explains.
The nearly indestructible qualities that make this material very difficult to recycle render it an excellent resource for backpacks. “The material is so durable, you almost cannot tear it,” Goosses adds and demonstrates with a hard tug that even when the material already has a hole, it won’t rip it further. The material is also water repellent and extremely light.
The antique Singer is still in their Cologne headquarters but only as decoration. Their company with 12 employees is producing 500 backpacks and fanny packs every week in Romania, where the parts are professionally cut by laser, dyed and sewed. Airpaq still procures the belt buckles at scrapyards but they get most of the airbags directly from the reject pile of a nearby airbag producer. “We process the materials where they are produced,” Goosses explains. Only about 15 miles lie between one of Europe’s biggest airbag manufacturers and the Airpaq seamsters in Romania.
Co-founders Adrian Goosses and Michael Widmann demonstrate their company's equation: airbag plus seatbelt equals a backpack that's durable and eco-friendly.
Airpaq
The founders are aware that with price tags ranging from 100 to 160 Euro - a cost that reflects their intensive production process - Airpaq’s bags are hardly competitive. After all, anybody can buy a discount backpack for a fraction of the cost. So they recently added fanny packs for 30 Euro to their product line. Goosses and Widmann know they will need to lower their prices in the long run if they want to expand. Among other things, they didn’t pay themselves salaries during the first two years after founding the company.
Money-making isn’t their only objective. “Of course, it would be cheaper if we did what almost all textile producers do and move production to Asia,” Goosses says. That wasn’t an option for him. “Ship trash to Vietnam and let seamsters sew it together for cheap? No way, that would be anything but sustainable,” he says.
Michael Widmann’s family was already operating a textile production in Romania, mainly producing thin, elastic sports fashion. The family allowed Widmann and Goosses to produce their first professional prototypes there, but then the two youngsters had to buy their own machines, acquire the necessary knowhow, and hire their staff. They both moved to Romania for six months “to get to know the people behind the machines.” The founders emphasize that they pay fair wages, use eco-certified dyes and clean their own wastewater. “Normal production uses five to six liters of water per kilo material,” Widmann explains. “We only need a fraction because we massage the dye into the material by hand: 100 ml water for washing and dying per kilo.”
However, every time they return to the scrapyard, the abundance of trash sparks new ideas. “When you see how much material ends up there…” Widmann says, shaking his head without finishing the sentence. Goosses picks up the train of thought: “We want to make upcycling the new standard. You just have to be creative to get upcycling into the mainstream.”
And maybe they’ll return to their roots and finally find an idea for the tires after all. “One could turn the rubber into soles for comfortable shoes,” Widmann thinks out loud.
COVID-19 vaccines for humans number 30, while only three vaccines are available for animals, even though many species have been infected.
“Several animal species have been predicted and found to be susceptible to SARS-CoV-2,” says Suresh V. Kuchipudi, interim director of the Animal Diagnostic Laboratory at the Huck Institutes of Life Sciences. But the risk remains unknown for many animals in several parts of the world, he says. “Therefore, there is an urgent need to monitor the SARS-CoV-2 exposure of high-risk animals in different parts of the world.”
In June, India introduced Ancovax, its first COVID-19 vaccine for animals. The development came a year after the nation reported that the virus had infected eight Asiatic lions, with two of them dying. While 30 COVID-19 vaccines for humans have been approved for general or emergency use across the world, Ancovax is only the third such vaccine for animals. The first, named Carnivac-Cov, was registered by Russia in March last year, followed by another vaccine four months later, developed by Zoetis, a U.S. pharmaceutical company.
Christina Lood, a Zoetis spokesperson, says the company has donated over 26,000 doses of its animal vaccine to over 200 zoos – in addition to 20 conservatories, sanctuaries and other animal organizations located in over a dozen countries, including Canada, Chile and the U.S. The vaccine, she adds, has been administered to more than 300 mammalian species so far.
“At least 75 percent of emerging infectious diseases have an animal origin, including COVID-19,” says Lood. “Now more than ever before, we can all see the important connection between animal health and human health."
The Dangers of COVID-19 Infections among Animals
Cases of the virus in animals have been reported in several countries across the world. As of March this year, 29 kinds of animals have been infected. These include pet animals like dogs, cats, ferrets and hamsters; farmed animals like minks; wild animals like the white-tailed deer, mule deer and black-tailed marmoset; and animals in zoos and sanctuaries, including hyenas, hippopotamuses and manatees. Despite the widespread infection, the U.S. Centres for Diseases Control and Prevention (CDC) has noted that “we don’t yet know all of the animals that can get infected,” adding that more studies and surveillance are needed to understand how the virus is spread between humans and animals.
Leyi Wang, a veterinary virologist at the Veterinary Diagnostic Laboratory, University of Illinois, says that captive and pet animals most often get infected by humans. It goes both ways, he says, citing a recent study in Hong Kong that found the virus spread from pet hamsters to people.
Wang’s bigger concern is the possibility that humans or domestic animals could transmit the virus back to wildlife, creating an uncontrollable reservoir of the disease, especially given the difficulty of vaccinating non-captive wild animals. Such spillbacks have happened previously with diseases such as plague, yellow-fever, and rabies.
It’s challenging and expensive to develop and implement animal vaccines, and demand has been lacking as the broader health risk for animals isn’t well known among the public. People tend to think only about their house pets.
In the past, other human respiratory viruses have proven fatal for endangered great apes like chimpanzees and gorillas. Fearing that COVID-19 could have the same effect, primatologists have been working to protect primates throughout the pandemic. Meanwhile, virus reservoirs have already been created among other animals, Wang says. “Deer of over 20 U.S. states were tested SARS-CoV-2 positive,” says Wang, pointing to a study that confirmed human-to-deer transmission as well as deer-to-deer transmission. It remains unclear how many wildlife species may be susceptible to the disease due to interaction with infected deer, says Wang.
In April, the CDC expressed concerns over new coronavirus variants mutating in wildlife, urging health authorities to monitor the spread of the contagion in animals as threats to humans. The WHO has made similar recommendations.
Challenges to Vaccine Development
Zoetis initiated development activities for its COVID-19 vaccine in February 2020 when the first known infection of a dog occurred in Hong Kong. The pharmaceutical giant completed the initial development work and studies on dogs and cats, and shared their findings at the World One Health Congress in the fall of 2020. A few months later, after a troop of eight gorillas contracted the virus at the San Diego Zoo Safari Park, Zoetis donated its experimental vaccine for emergency use in the great ape population.
Zoetis has uniquely formulated its COVID-19 vaccine for animals. It uses the same antigen as human vaccines, but it includes a different type of carrier protein for inducing a strong immune response. “The unique combination of antigen and carrier ensures safety and efficacy for the species in which a vaccine is used,” says Lood.
But it’s challenging and expensive to develop and implement animal vaccines, and demand has been lacking as the broader health risk for animals isn’t well known among the public. People tend to think only about their house pets. “As it became apparent that risk of severe disease for household pets such as cats and dogs was low, demand for those vaccines decreased before they became commercially available,” says William Karesh, executive vice-president for health and policy at EcoHealth Alliance. He adds that in affected commercial mink farms, the utility of a vaccine could justify the cost in some cases.
Although scientists have made tremendous advances in making vaccines for animals, Kuchipudi thinks that the need for COVID-19 vaccines for animals “must be evaluated based on many factors, including the susceptibility of the particular animal species, health implications, and cost.”.
Not every scientist feels the need for animal vaccines. Joel Baines, a professor of virology at Cornell University’s Baker Institute for Animal Health, says that while domestic cats are the most susceptible to COVID-19, they usually suffer mild infections. Big cats in zoos are vulnerable, but they can be isolated or distanced from humans. He says that mink farms are a relatively small industry and, by ensuring that human handlers are COVID negative, such outbreaks can be curtailed.
Baines also suggests that human vaccines could probably work in animals, as they were tested in animals during early clinical trials and induced immune responses. “However, these vaccines should be used in humans as a priority and it would be unethical to use a vaccine meant for humans to vaccinate an animal if vaccine doses are at all limiting,” he says.
William Karesh, president of the World Animal Health Organization Working Group on Wildlife Diseases, says the best way to protect animals is to reduce their exposure to infected people.

In the absence of enough vaccines, Karesh says that the best way to protect animals is the same as protecting unvaccinated humans - reduce their exposure to infected people by isolating them when necessary. “People working with or spending time with wild animals should follow available guidelines, which includes testing themselves and wearing PPE to avoid accidentally infecting wildlife,” he says.
The Link between Animal and Human Health
Although there is a need for animal vaccines in response to virus outbreaks, the best approach is to try to prevent the outbreaks in the first place, explains K. Srinath Reddy, president of the Public Health Foundation of India. He says that the incidence of zoonotic diseases has increased in the past six decades because human actions like increased deforestation, wildlife trade and animal meat consumption have opened an ecological window for disease transmission between humans and animals. Such actions chip away at the natural barriers between humans and forest-dwelling viruses, while building conveyor belts for the transmission of zoonotic diseases like COVID-19.
Many studies suggest that the source of COVID-19 was infected live animals sold at a wet market in China’s Wuhan. The market sold live dogs, rats, porcupines, badgers, hares, foxes, hedgehogs, marmots and Chinese muntjac (small deer) and, according to a study published in July, the virus was found on the market’s stalls, animal cages, carts and water drains.
This research strongly suggests that COVID-19 is a zoonotic disease, one that jumps from animals to humans due to our close relationship with them in agriculture, as companions and in the natural environment. Half of the infectious diseases that affect people come from animals, but the study of zoonotic diseases has been historically underfunded, even as they can reduce the likelihood and cost of future pandemics.
“We need to invest in vaccines,” says Reddy, “but that cannot be a substitute for an ecologically sensible approach to curtailing zoonotic diseases.”
