Nope, you didn’t read that wrong. Human hair is compostable and recyclable. Hair from your hairbrush or fur from your pet are full of useful nitrogen that can be thrown in the compost pile. Donating your hair could help clean up future oil spills. San Francisco nonprofit Matter of Trust collects human and pet hair to create booms that soak up oil. Currently, warehouses are full, but you can be placed on the email alert list when the need arrives again.
