CAMBRIDGE, Mass., May 27, 2014 /PRNewswire/ --Metabolix, Inc. (NASDAQ: MBLX),
an advanced biomaterials company focused on sustainable solutions for the
plastics and chemicals industries, today announced that it will highlight
advances in its PHA (polyhydroxyalkanoate) biopolymer technology and its uses
in modifying PLA (polylactic acid) at the 3^rd PLA World Congress taking place
May 27 and 28 in Munich, Germany. Metabolix Vice President, Biopolymers, Bob
Engle will present on PHA performance modifiers for PLA at the conference.

Metabolix, Inc.

"There is a significant opportunity to expand the range of applications
addressable by PLA, the current industry-leading biopolymer material, by
rubber toughening it with PHA modifiers," Engle said. "We are developing
proprietary PHA copolymer technology that is compatible with PLA and can
modify PLA's properties to provide significant improvement in toughness and
ductility, while still satisfying the market need for high bio-content and
compostable solutions in applications such as single-use nonwovens, blister
packaging and film."

Overview of Metabolix's PLA World Congress Presentation:

"PLA Modification Using New Mirel™ PHA Copolymers"
Tuesday, May 27 at 4:35 p.m. CEST

Metabolix has developed amorphous copolymers characterized with low glass
transition temperatures to extend its PHA biopolymer performance capabilities.
These PHA copolymers can effectively improve PLA's physical properties without
compromising transparency, bio-content or compostability. Metabolix will
showcase opportunities in a range of applications including fibers, sheet and
film that are enabled by using Metabolix PHA modifier technology and highlight
data on the PLA performance improvement. Metabolix is launching PLA
masterbatch compounds incorporating the new Mirel PHA copolymers.
