Develops catalysts for clean energy production

Dr. Ariel Friedman, develops solutions in the field of electrochemistry that will lead to green and cheap energy
The enzymes of the start-up company break down the polyethylene terephthalate plastic into its monomers: terephthalic acid as well as ethylene glycol, which themselves can be used directly in existing plants to re-produce the polymer

Plastic recycling with the help of enzymes

  • No comments
The French biotech start-up company called 'Carbios' succeeded in developing an enzymatic process to recycle the plastic polyethylene terephthalate (Polyethylene terephthalate) back to its component monomers, from which the finished polymer can be produced again

The enzyme aminoacyl synthetase (in green) recognizes a tRNA molecule (brown) and attaches an amino acid to it. Correct identification of the molecule is made according to the areas shown here in red. The Technion researchers discovered that the enzyme also knows how to recognize another type of RNA molecule (mRNA). Moreover, the correct recognition of the mRNA depends on regions that are very similar to the recognition regions of tRNA (marked here in red). Credit: Prof. Yoav Araba, Technion
