At its workshop in San Francisco, Matter of Trust produces mats made from donated human hair and animal fur, to soak up oil spills. They have been used to clean up minor spills, like this one caused by a road accident, and are also helpful for major spills.

Pictured, Matter of Trust volunteers using hair mats to clean up oil from a San Francisco beach in 2007, after the Cosco Busan container ship spilled more than 50,000 gallons of oil following its collision with the San Francisco Bay Bridge.

Every day, Matter of Trust receives packages of ponytails in the post.

Its staff process the hair using a nail board and brushes, as well as felting machines.

The finished mats are two foot square and one-inch-thick, and can adsorb up to 1.5 gallons (5.6 liters) of oil.

Matter of Trust founder Lisa Gautier says she has noticed that a lot of red hair is donated from the Boston area.

The hair mats can be rolled into booms to collect vehicle oil from the street. The goal is to keep oil out of storm drains that flow into waterways.

Matter of Trust is expanding its network of local partner hubs, producing mats with locally sourced hair in 17 countries across the globe.
