We believe that a healthy, sustainable world is possible: A world where the spaces in which we live, work, and play help us breathe easy, think clearly and feel more creative. Communities where all children thrive in schools, playgrounds and homes free of chemicals that harm developing bodies and minds. A future when our collective health soars because of our built environment.

We believe that a new generation of manufacturers and product developers is already among us: Visionaries committed to creating healthy, long-lasting, and renewable materials.

This is HBN’s dream: All people and the planet thrive when the environment is free of toxic chemicals. We invite you to join us as we bring this dream to life.
