Description:
This proposal seeks to revolutionize plastic production through the exploration of polymers derived from biocompatible flavor and fragrance (F&F) molecules and natural products. F&F portfolios have for decades evolved towards bio-based and natural products, adhering to stringent safety regulations for human and environmental well-being. Leveraging these molecules for polymer synthesis we could accelerate the development of bio-based and environmentally friendly plastic alternatives.
Objective:
The objectives of our proposed project are as follows: 1) Introduce an innovative methodology for polymer synthesis using biocompatible (and potentially bio-based) F&F building blocks; 2) Develop a fully characterized polymer portfolio, encompassing structure- property relationships and thermal, mechanical, and biodegradation/recyclability attributes derived from F&F building blocks; 3) Establish a democratized open-access database of the F&F polymer portfolio, with dissemination on the University of Colorado's Polymer Solutions for the Environment (POSE) and the Macromolecular Alliance, Community, Resources, and Outreach (MACRO) websites; and 4) Complete Techno- Economic Analysis (TEA) and Life Cycle Assessment (LCA) for selected F&F polymers.
Approach:
F&F molecules will be selected based on criteria such as derivation from bio-renewable feedstocks, possessing polymerizable structures, and cost. Using conventional and well- established polymerization techniques, F&F polymers will be synthesized. Comprehensive characterization of polymer properties including thermal and mechanical properties, microstructure, biodegradability, and recyclability will be conducted, resulting in the development of a well-characterized and diverse F&F polymer portfolio. Comparative analysis with conventional plastics will inform the selection of 1-2 materials for subsequent TEA and LCA to benchmark against conventional, commodity plastics to demonstrate economic and environmental advantages and disadvantages when using F&F building blocks.
Expected Results:
Anticipated outcomes include an open-access database showcasing the properties of F&F polymers synthesized in this project, poised to revolutionize sustainable plastic production. The data and methods generated from this program will lead to actionable, scalable change toward polymer products that support sustainable chemistry. Overall, we anticipate this database will foster knowledge dissemination and advance environmental consciousness to ensure the safety of plastics for people and the environment.
