Eggshells: The next innovative frontier to Bioplastics

University: Tuskegee University

Objective of study: Researchers wanted to create a packaging material that could take the place of bulky plastic molds and cardboard and could be used to wrap, cushion and protect commercial products during transit

Process and applications:

  • Amazingly light, durable during transport and ample in supply, eggshells serve as a ready-made, self-contained incubator for many species, from the duck-billed platypus to the barnyard chicken
  • By including the nanoparticles of eggshells into bioplastics, they could more easily blend different forms of polymers together
  • By grinding the eggshell down and then blasting it with sonic waves, they were able to convert the calcium carbonate shell into  nanoparticles


  • This is a product that can be used in place of conventional plastic bags and film, that is 700 percent more pliable than standard bioplastic blends
