CAMBRIDGE, Mass., Feb. 18, 2014 /PRNewswire/ -- Metabolix, Inc. (NASDAQ:
MBLX), an innovation-driven performance biomaterials company delivering
sustainable solutions to the plastics, chemicals and energy industries, today
announced recent advancements in the development of the Company's PHA
(polyhydroxyalkanoate) biopolymer technology. Rubber modifiers are introduced
for improving the performance of PLA (polylactide) biopolymers. Metabolix Vice
President, Biopolymers, Bob Engle will present these developments at the
Innovation Takes Root 2014 Conference, taking place February 17 – 19 in
Orlando, Florida.

Metabolix has developed new amorphous PHA biopolymers with the physical
characteristics of a low Tg rubber. These new rubber modifiers have been shown
to improve the ductility and flexibility of PLA, while also retaining clarity
and compostability. In PLA extrusion applications, Mirel^TM rubber modifiers
lower stiffness and brittleness and improve tactile feel. In PLA film
applications these rubber modifiers also increase tear resistance. PHA and PLA
biopolymers are both biobased and compostable, making them attractive for
sustainability and performance-driven business opportunities. 

"Metabolix continues to make great progress in the use of our core PHA
technology as a performance-driven modifier in applications where improved
performance of both biobased and conventional polymers such as PLA and PVC is
desired," said Joseph Shaulson, president and CEO of Metabolix. "In this case,
Mirel rubber modifiers have the potential to expand the application space for
PLA which may lead to new business opportunities."

"These innovative Mirel rubber modifiers are an exciting extension to the
Metabolix PHA technology platform. Their capability to modify and improve PLA
demonstrates performance that is comparable to traditional non-renewable
rubber modifiers without compromising the renewable nature of PLA or key
features of clarity and compostability," added Bob Engle, vice president,
biopolymers of Metabolix. "We look forward to presenting our new biobased
rubber modifiers for PLA at Innovation Takes Root.

"Overview of Innovation Takes Root 2014 Panel Presentation:

"Metabolix Launches PHA Modifiers for PLA in 2014," part of "Broadening the
Application Space for Ingeo Films" Panel
Tuesday, February 18 at 2:00 p.m., Grand Ballroom 1-2

Engle will present data showcasing Metabolix's extended range of PHA
compositions into the amorphous regime to offer a unique way to compound PLA.
The Metabolix bio-elastomers modify PLA, improving physical properties without
compromising clarity. In PLA films, Metabolix modifiers lower the modulus and
improve tear resistance. In extruded and molded parts, the PHA modifiers
improve ductility and reduce brittle fracturing. Distinctly high bio-content
and biodegradability set Metabolix PHA modifiers apart from traditional
non-renewable counterparts.
