CAMBRIDGE, Mass., Oct. 1, 2013 /PRNewswire/ --Metabolix, Inc. (NASDAQ: MBLX),
an innovation-driven performance biomaterials company delivering sustainable
solutions to the plastics, chemicals and energy industries, today announced
the launch of I6003rp, a new biobased polymeric performance additive for
recycled PVC (polyvinyl chloride). I6003rp demonstrates the value of
excellent miscibility in PVC when used in combination with recycle PVC. This
certified biobased process aid lowers processing torque and improves
properties.

With increasing PVC waste coming from short-life products such as packaging,
bottles and medical devices, as well as from long-life products such as pipes,
window frames and cable insulation that have been in service for significant
time and are increasingly being replaced, more PVC is entering the waste
stream. "While PVC is one of the largest recycled polymers by volume, the
amount of discarded post-industrial scrap and post-consumer waste that is
actually recycled is still very low compared to the amount that is landfilled
every year. Due to deterioration in physical properties when reprocessed,
scrap PVC is downgraded and devalued," said Bob Engle, vice president,
biopolymers, at Metabolix.

"I6003rp is a performance-driven additive that improves toughness and makes
processing easier, enabling PVC converters to increase the rate of recycle use
without compromising hardness. PVC Repro suppliers can upgrade the quality and
value of Repro products," added Bob Engle.

Metabolix developed I6003rp based on data confirming that specific Metabolix
grades of PHA (polyhydroxyalkanoate) have superb miscibility with PVC and
enhance the processing and properties of recycled PVC. Dr. Yelena Kann,
product development scientist at Metabolix, will be presenting this data at
SPE Vinyltec 2013 being held October 21-23, 2013.

In 2012, Metabolix launched I6001, a biobased polymeric modifier for flexible
and semi-rigid PVC that brings toughness, elongation and plastification
without migration or compromising clarity. I6003rp represents an extension
of the product line. With this process aid, Metabolix continues to drive
advancements in the use of performance biopolymers for PVC manufacturing by
harnessing the power of its innovative PHA-technology platform.

At K 2013, taking place from October 16 – 23, 2013 in Dusseldorf, Germany,
Metabolix will be showcasing I6003rp and I6001 PVC modifiers, Mvera B5010, a
new compostable film grade resin, and a number of additional biobased master
batch and bio-composite resin products. For more information on I6003rp,
including a product bulletin, please visit the product page.
