NatureSphere™ is a 100% natural cellulose material made only from managed forestry sources and processed into a spherical shape using a special, organic solvent-free manufacturing method. After use, even if it flows into the ocean or into soil, it will biodegrade into CO2 and H2O and natural biomass. Originally developed by Futamura, NatureSphere™ is ecologically benign, both as a product and in the manufacturing process. In addition, it is chemically resistant and does not dissolve in alcohol or organic solvents, and is also heat resistant.
