Refine and simplify this into 5 sentences for a non technical audience   Petrochemical-based plastics are coming under increasing scrutiny and regulatory scrutiny for their non-biodegradeability and impact on the global ecosystem. As we search for alternate material advanced materials to drive G Corps future growth we are exploring new Biopolymer technologies. This presentation will focus on two promising materials we are researching at different ends of the commercial spectrum DeNovo Proteins and Polyhydroxyalkanoates. DeNovo proteins are synthetic proteins computationally designed using the most advanced emerging artificial intelligence programs (Alphafold, Rosetta, RFDiffusion) to provide un precedented control over macromolecular structure. PHAs are commercial megaton scale plastic materials  with a history of use in implantable medicine and  experiencing rapid growth in the market as a biodegradable compost compatible materials replacing single use disposable petrochemical plastics.  The presentation will discuss how precise engineering and control over macromolecular structure and properties and processing in core technology promises to provide new material alternatives.
