About Us

Being parents of two, we hate to see disposable diapers go into waste and pile up in landfills. As polymer scientists and engineers, we know how precious the materials used in disposable diapers are. We started Zynnovation LLC to develop novel technologies and give a second life to disposable diapers. We have created and validated a multifunctional plant protection mat, trademarked as TreeDiaper® and SteadSpring®.
TreeDiaper® technology are patented in the United States (US Pat #: 9,565,809, 10,178,834 and 10,624,276) and Israel while pending in a number of other countries around the world.

All products are proudly made in the USA.
