Rennovia produces cost-advantaged 100% bio-based nylon-6,6 polymer; automotive apps
2 October 2013
Rennovia, Inc., a privately held company that develops novel catalysts and processes for the cost-advantaged production of chemical products from renewable feedstocks, has produced and shipped to a prospective partner samples of what it believes to be the world’s first 100% bio-based nylon-6,6 polymer. (Earlier post.) Nylon-6,6 is a widely used high-performance engineering resin, used especially in the automotive market for its strength, light weight, and performance at high temperatures.
Nylon-6,6 is also used in a wide range of fiber applications, including textiles, carpets, technical fibers and tire-cord. More than 6 billion pounds (2.7 billion kg) of nylon-6,6 (also known as polyamide-6,6 or PA66) is currently produced per year from petroleum-derived adipic acid (AA) and hexamethylenediamine (HMD), representing a global market of more than $6 billion.
The new bio-polymer, produced under Rennovia’s RENNLON brand, is made from Rennovia’s renewable monomers, RENNLON adipic acid (AA) and RENNLON hexamethylenediamine (HMD).
Rennovia previously announced the production of bio-based adipic acid (AA) and bio-based hexamethylenediamine (HMD) from widely available, renewable feedstocks, using its proprietary chemical catalytic process technology. Rennovia’s AA and HMD processes employ proprietary catalyst technology developed using its advanced high-throughput catalyst discovery and development platform.
Production costs for Rennovia’s bio-based AA and HMD are projected to be 20-25% below that of conventional petroleum-based AA and HMD, with a significantly lower per-pound capital cost. Additional projected benefits include an 85% reduction in greenhouse gas (GHG) emissions compared to conventional petroleum-derived AA, and a 50% reduction in GHG emissions compared to conventional petroleum-derived HMD.
The production of 100% bio-based nylon-6,6 further validates Rennovia’s unique ability to create technological breakthroughs in the production of bio-based chemicals and materials, with projected significant cost advantages and environmental benefits vs. products produced from petroleum-based feedstocks.
Practicing our AA and HMD processes at demonstration scale is the next important milestone for the company.—Robert Wedinger, President and CEO of Rennovia
