Brazil implements human hair barriers to combat ocean pollution

A new environmental initiative in Brazil is utilizing donated human hair to create protective barriers against ocean pollution. The project, led by Mariana Robrahn and her NGO Fiotrar, aims to mitigate the impact of oil spills, biodiesel, and other pollutants on the coastline.

Initial testing has taken place in Enseada de Bom Jesus within Guanabara Bay, Rio de Janeiro. The technology involves hair-filled cylinders attached to floating barriers that can remain in the water for up to four months to trap contaminants. This method is inspired by similar technologies used in Chile and the United States.

The project leverages Brazil’s high density of hair salons to secure a nearly inexhaustible supply of raw material. Local hair salons donate hair that is otherwise unsuitable for wig-making. This initiative addresses long-standing pollution issues in Guanabara Bay caused by heavy maritime traffic, which local fishermen report has severely impacted fish populations and their livelihoods.
