Abstract: A biological cement including algal biomatter, cement, and water. The present disclosure also provides methods of preparing the biological cement. The biological cement can be used in place of traditional cement, for instance by being incorporated into mortar or concrete for structural or other applications. The algal biomatter may include one or more of biomass from Chlorella, Spirulina (Arthrospira platensis), Saccharina latissima, Ulva spp. (such as U. lactuca or U. expensa), Agarophyton, Sargassum, Gracilaria parvispora, Halymenia hawaiiana or Caulerpa lentillifera.

Abstract: Bioplastic compositions and methods of making are described herein. The various mechanical and physical properties of the bioplastic may be varied by altering the thermoforming or incorporating an additive depending on the desired mechanical and physical properties of the end product. The bioplastic may be made entirely of biomatter and be backyard compostable.
