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.

Zynnovation LLC is an established, women, and minority-owned and operated company located in Ashland, Virginia. The company is pursuing the development of green technologies based on innovative scientific practices for a better world. We are currently working on the following areas:

  • Increase Tree Canopy by promoting tree planting and reducing the hurdle of tree planting.
  • Reduce Carbon Footprint by reducing solid waste and reusing/re-purposing solid waste materials.
  • Reduce Water Usage by increasing rainwater harvesting, reducing stormwater runoff and reusing of stormwater for vegetation establishment
  • Protect Our Environment by reducing pollution and erosion
  • Improve Quality of Life by promoting green spaces, reducing labor requirement and increase survival of trees
