Innovative environmental solution in Xochimilco: the use of human hair is transforming the cleaning of its canals and offering new hopes for the Mexican axolotl, a species in danger of extinction.
This project uses hair filters capable of absorbing up to five times their weight in pollutants, attempting to reverse years of damage in this important wetland. These filters promise an ecological solution to the environmental degradation that has threatened the survival of the axolotl.
For years, the axolotl has faced a dramatic decline in its population due to the pollution of the Xochimilco canals. Waters loaded with heavy metals, domestic waste, and bacteria have made the environment unsustainable for this species.
Human hair, traditionally considered waste, is now strategically used to purify the water. Each filter contains approximately one kilo of hair, allowing it to trap oils and other pollutants.
To date, twenty of these filters have been placed in the canals, showing encouraging results. Each device can operate for up to two months and is cleaned with bacteria for reuse or integration into the soil without leaving residue.
Human hair cleans canals
A network of 33 barbershops and hair salons is fundamental to this project, collecting around 202 kilos of hair annually to manufacture the filters. This creates a sustainable cycle, demonstrating how simple and everyday actions can have a significant impact on the conservation of the environment.
As more filters are installed, experts suggest that their use in some 500 trajineras would allow for continuous large-scale cleaning, promoting the recovery of the axolotl habitat.
Integrated into an international network that has been using hair for water decontamination for decades, this innovative technology combines with local efforts to restore the ecosystem of Xochimilco.
The project demonstrates that the use of human hair to clean canals and save the axolotl in Mexico is no longer just a proposal but a tangible and promising reality.
With the support of hair salons providing the necessary raw material, this ecological effort continues to grow. Specialists argue that greater implementation of these filters could facilitate a sustained recovery of the local ecosystem.
