Safer Alternatives

This is a directory of green chemistry and engineering technologies from around the world, developed by the Yale-UNIDO Global Green Chemistry Initiative. It provides a worldwide snapshot of technologies that are currently commercially available or are in the process of becoming commercially available. The selected technologies are applicable across a broad range of sectors and industries.

Results are displayed alphabetically by title. Use the search bar to refine results. Text searches are full text, not partial word searches. You can also submit new technologies to share with the green chemistry community. If you are not logged in, you will be redirected to login first.
