Microalgae for Bioplastics

Microalgae for Bioplastics

Microalgae haveunique growth yields, so using microalgae to produce bioplastics offers an excellent opportunity to increase the sustainability of plastic use. Microalgae, as a potential source for the production of bioplastics, can be used either directly as biomass or as a feedstock for secondary processing. Here, Lifeasible offers specialized solutions for the bioplastics of microalgae.

Introduction

Plastics have become one of the most essential requirements of modern life. Continued reliance on petroleum-based, non-biodegradable plastics has led to increased global environmental damage and rapid depletion of fossil fuels. Biobased plastics are becoming increasingly popular as marketed alternatives to fossil-based plastics, and they have properties very similar to petroleum-based plastics. Plant-based raw materials, natural polymers, and other small molecules are available for bioplastic production. However, bioplastics derived from crops compete with the food supply. Therefore, microalgae are a potentially better source of biomass for bioplastics production due to their unique advantages.

Customized Solutions

The production of bioplastics from microalgae represents a new opportunity for exploration and further improvement. We chose microalgae for bioplastic production because it does not compete with food sources, can grow on waste resources, and can achieve high lipid accumulation. In addition, using microalgae to produce bioplastics can be more sustainable and contribute to the circular and bio-economy. Our scientists are exploring a variety of strategies for converting microalgae to bioplastics, including:

Direct Use of Microalgae Biomass as Bioplastics

Microalgae produce high biomass and metabolites that can be processed into many value-added products. We can achieve direct molding of algal metabolites and algal biomass into bioplastic beads or sheets.

Blending Microalgae Biomass with Petroleum and Bioplastics

We blend microalgae biomass with petroleum plastics to extend the life of microalgae plastics and provide value-added mechanical properties.

Intermediate Processing in a Biorefining Environment

We offer a biorefinery approach to microalgae bioproduct production that reduces the overall cost of the system, allowing microalgae-based bioplastics to be produced at a low cost.

Creation of Microalgae Bioplastic Production Strains through Genetic Engineering

We sequence various microalgae strains and try to incorporate them into different products that may be produced. We offer the implantation of the polyhydroxy butyrate (PHB) pathway into microalgae strains.

Tests for Bioplastic Characterization and Performance

We offer mechanical testing, thermal-based analytical methods, SEM, and FT-IR to test microalgal bioplastics to determine properties and study their structural and molecular properties.

As an innovator in microalgae research, Lifeassible offers comprehensive solutions for the design of microalgae-based bioplastics. We have successfully developed a wide range of microalgae bioplastics, including but not limited to the following:

  • Polyhydroxyalkanoates (PHA)
  • Polyurethane (PU)
  • Polylactic acid (PLA)
  • Cellulose acetate (CA)

Features of Our Microalgae Bioplastics

  • Energy efficient.
  • Flexible modification, can be designed to any size, or shape.
  • No toxic by-products.
  • Biodegradable.

Applications of Our Microalgae Bioplastics

  • Food packaging, whether for freshness or long-term storage.
  • Agriculture, such as greenhouse films, protective nets, and grow bags, are used to maintain proper conditions and protect crops from physical and biological risks.
  • Medicine, including engineering biological tissues such as bone, cartilage, and skin.
  • Environment. PHB is an antifouling compound that can be mixed with other metals and applied to the hull of ships to prevent the settling of unwanted marine life.

At Lifeasible, we can can quickly design greener and safer microalgae-based bioplastics. We are your trusted partner in all aspects of microalgae research. If you are interested in our solutions, please do not hesitate to contact us.
