Introduction
The global reliance on petroleum-derived plastics has led to a growing environmental crisis,
with widespread pollution and the depletion of non-renewable resources. In response, there is
an urgent need to reduce plastic usage and develop sustainable alternatives that can address the
shortcomings of conventional plastics. Bioplastics, derived from renewable biological sources,
have emerged as a notable contributor to this effort.
This study explores the potential of the cyanobacterium Spirulina platensis as a feedstock for
the production of bioplastic materials. Spirulina is a nutrient-rich microalgae that has garnered
significant attention for its diverse applications in the fields of food and biofuels. Its ability to
accumulate polyhydroxybutyrate (PHB), a type of polyhydroxyalkanoate (PHA), makes it an
attractive candidate for bioplastic development.
The primary objectives of this study are cultivating Spirulina platensis under controlled
conditions and optimize its growth, extraction of the PHB within the its biomass, and using
Spirulina as a biological source for the fabrication of bioplastic films. By leveraging the
inherent properties of Spirulina, this research aims to demonstrate the feasibility and potential
of this microalgae as a sustainable alternative to conventional petroleum-based plastics.
The findings contribute to expanding the knowledge base concerning the application of
microalgae in the advancement of environmentally friendly bioplastic materials. The
successful production and characterization of Spirulina-based bioplastics could pave the way
for the adoption of this renewable resource in various industries, ultimately reducing the
environmental impact of plastic waste and promoting a more sustainable future.
