Revolutionizing plastic recycling: FAST-PETase enzyme variant

Background

Plastic waste is a pressing ecological challenge, with a staggering 8.3 billion metric tons produced, of which 6 billion tons become waste. Traditional methods of plastic degradation, such as chemical processes, are costly and generate harmful byproducts. Enzymatic degradation presents a sustainable alternative, with poly (ethylene terephthalate) (PET) comprising 12% of global solid waste. However, existing enzymes like PETase lack robustness and efficiency.

Technology overview

FAST-PETase, an enzyme variant developed at The University of Texas at Austin, addresses these limitations. Utilizing machine learning, novel mutants of PETase were generated, capable of breaking down PET plastics within 24 hours. This innovation offers rapid and efficient degradation of untreated post-consumer PET plastics from various sources.

Benefits

  • Up to 107% increase in degradation rates of plastics at 70°C
  • Accelerated process of plastic degradation, enabling efficient recycling of PET plastics
  • Facilitates the transition towards a circular plastics economy by converting plastics into recyclable monomers
  • Mitigates environmental threats posed by plastic waste accumulation in landfills and oceans
  • Offers a sustainable solution to plastic pollution while promoting environmental responsibility

Application

The technology finds application in industries involved in recycling plastics or plastic production, offering a sustainable solution to the global plastic waste crisis. By efficiently breaking down plastics into recyclable monomers, it contributes to mitigating environmental damage caused by plastic pollution.

Opportunity

With a lab/bench prototype stage, the technology is poised for further development towards commercialization. Companies engaged in plastic recycling or production stand to benefit from integrating this innovative enzymatic degradation technology into their processes, promoting sustainability and environmental responsibility.
