Rennovia Launches Hexamethylenediamine As Next Product, Enabling 100% Bio-Based Nylon-6,6

MENLO PARK, Calif. — April 24, 2013 — Rennovia, Inc. (Rennovia), a privately held company that
develops novel catalysts and processes for the cost advantaged production of chemical products from
renewable feedstocks, announced at the PCI 6th American Nylon Symposium that it has successfully
demonstrated production of hexamethylenediamine (HMD) from widely available, renewable
feedstocks.  Coupled with Rennovia’s previously announced renewable adipic acid, this enables
for the first time the production of 100% bio-based nylon-6,6 from monomers derived from
bio-renewable feedstocks using chemical catalytic technology. 

Rennovia’s HMD process employs proprietary catalyst technology developed using its advanced
high-throughput catalyst discovery and development platform.  “Practicing our HMD process at
demonstration scale is the important next milestone for the company,” said Robert Wedinger,
President and CEO of Rennovia.  Production costs for Rennovia’s bio-based HMD are projected to
be 20-25% below that of conventional petroleum-based HMD, with a significantly lower per-pound
capital cost.  Additional projected benefits include a 50% reduction in greenhouse gas (GHG)
emissions compared to conventional petroleum-derived HMD.  “The development of our HMD process
further validates Rennovia’s unique ability to create technological breakthroughs in the production
of bio-based chemical products, with projected significant cost advantages vs. products produced
from petroleum-based feedstocks” added Wedinger.

Over 3 billion pounds of HMD is currently produced per year from petroleum-derived propylene
or butadiene, representing a global market of more than $4 billion.  It is used in the
manufacture of nylon-6,6 for resin and fiber applications, as well as in polyurethanes.  These
are used in a wide range of consumer goods, including interior, exterior and under-the-hood
automotive parts, coatings, tires, shoes, apparel, and carpeting.
