People generate a huge amount of hair waste. Nearly all of that waste ends up in landfill, where it can release harmful greenhouse gases that contribute to climate change. But hair possesses such useful qualities that it’s a shame to simply throw it away. That’s why people all around the world, like Hama, have been collecting hair and finding innovative ways to recycle it, including making mats (垫子) out of it for removing oil leaks.
Hama is part of the nonprofit Matter of Trust (MoT) members working at more than 60 centers dotted across 17 countries, using machines to make hair donated from local salons and individuals into square mats, which are then used to clean up the floating oil. “Hair is particularly well-suited for this,” says MoT co-founder Lisa Gautier. “That’s because its rough (粗糙的) sort of outer layer lets oil stick to it.” MoT’s mats have been used in major oil leaks, including the 2010 Deepwater Horizon and 2007 Cosco Busan incidents.
In a 2018 study, Murray, an environmental scientist at the University of Technology Sydney in Australia, found that mats made of recycled human hair could absorb 0.84 grams of oil onto its surface for every gram of hair — significantly more than polypropylene, a type of plastic that’s typically used to clean up floating oil. Besides, hair is also useful as fertilizer (化肥). Hair contains a relatively high nitrogen, a chemical element crucial for plant growth, and each lock of hair is made of roughly 16 percent of this essential nutrient. Last year, more than 560 gallons of liquid fertilizer made from human hair was sold to farmers in northern Tanzania and the feedback from the farmers has been very encouraging.
“It’s just a great way to use hair in a productive way. Hair is an answer literally hanging in front of our eyes — for oil and soil,” Hama says.
