Abstract
Super absorbent polymers (SAPs) are crosslinked polymer chains that absorb and retain large amounts of fluid. Their largest consumer-based application is in the fabrication of diapers, adult incontinence pads, and feminine hygiene products – cumulatively representing a global $7 billion/yr market. SAPs are also widely used in many other industries. Most commercial SAPs are crosslinked polyacrylates (PAAs) or polyacrylamides (PAMs), both of which are typically made from petroleum-based resources and also have poor end-of-life properties. This SBIR Phase I project aims to develop a natural, low-cost, biodegradable, bio-based, and high- performance replacement SAP of the petroleum-derived PAA-based and PAM-based SAPs. Specifically, ZymoChem will explore various crosslinkers and crosslinking methodologies for converting the linear bio-derived polymer chains that are produced using ZymoChem’s proprietary microbes and fermentation technology into SAPs with both superior performance as well as superior end-of-life properties (e.g., biodegradability and recyclability) compared to traditional SAPs used for hygiene applications. The work plan for this Phase I project will involve [1] evaluating various crosslinking methodologies compatible with water for making 100% bio-based SAPs; [2] demonstrating substantially improved biodegradability compared to traditional petroleum-based SAPs, plus the potential for recyclability; and [3] demonstrating superior performance-based properties of the bio-based SAP compared to petroleum-based SAPs. Ultimately, the work during this project will serve as a crucial stepping stone toward establishing a low-cost, biodegradable, bio-based, and high-performance replacement of petroleum-based SAPs for hygiene applications.
