Oshenite® - natural, biorenewable, biocarbonate

Oshenite® is oolitic aragonite a mineral which is created naturally in the ocean as part of a unique ocean renewal cycle where microscopic sized bio matter such as plankton and algae are churned in carbonate rich waters forming oolites. These small oolites precipitate in infinite amounts forming sediment banks of ultra-pure calcium carbonate. Research studies indicate that the phenomenon produces vast amounts of the mineral (estimates are 20 million tons a year) For more info see the Research Abstract: Microbial Lime-Mud Production and Oshenite® - A Renewable Resource

Oshenite® - a perfect fit with a bioplastic strategy

As a naturally renewable, ocean sourced, high quality form of precipitated calcium carbonate, Oshenite® can provide a "foundation" for bioplastic resins and products.

Oshenite® enhances the ability of biobased plastics to compete with fossil fuel based materials. Specifically:

  • The addition of Oshenite® to a bioplastic will help reduce overall material costs without sacrificing performance and lessens the need for non renewable components.
  • Oshenite® speeds up degradation times due to the high PH factor and unique crystalline structure.
  • As a product that is not used for other applications like some food or agricultural based bioplastics alternatives, there is no issue or controversy related to conflicting uses or applications.
  • The renewable mineral deposit has 1 billion ton reserve of Oshenite® available get more info
