Rennovia Develops Rennlon™ Biobased Nylon 6,6 Polymer

Rennovia Inc., United States, has produced what it believes is the first 100-percent biobased nylon
6,6 polymer and has sent samples to a prospective production partner.

Rennlon™ polymer is made using Rennovia’s biobased Rennlon adipic acid (AA) and
hexamethylenediamine (HMD) monomers that are produced via the company’s proprietary chemical
catalytic process technology using widely available renewable glucose feedstocks. Rennovia projects
production costs for its monomers will be 20- to 25-percent lower than petroleum-based AA and HMD
production costs. The company also anticipates Rennlon AA and HMD production will generate
85-percent and 50-percent less greenhouse gas (GHG) emissions, respectively, compared to
petroleum-based AA and HMD production.
