FIRST BATCH OF ISOBUTENE FROM RENEWABLE RESOURCES DELIVERED TO ARKEMA

Evry (France), May 5th, 2015 - Global Bioenergies (NYSE Alternext Paris:
ALGBE) announces the delivery of the first batch of isobutene from
renewable resources to Arkema six months ahead of the projected schedule.

Since its startup in November 2014, Global Bioenergies' industrial pilot -
installed on the Pomacle-Bazancourt agro-industrial site near Reims in
France - has been operated almost continuously with the support of ARD, an
affiliate of French sugar producer Cristal Union. The first tasks consisted
in scaling up the fermentation results achieved in the laboratory, followed
by the startup of the purification and packaging module to allow the
production of purified isobutene batches.

Global Bioenergies announces today that the first batches of isobutene from
renewable resources have been packaged and shipped. The entire production
chain has therefore been integrated for the first time: wheat
starch-derived glucose has been converted into gaseous isobutene by
single-step fermentation, which has in turn been purified and liquefied,
before being packaged in pressurized cylinders dedicated to the transport
of industrial gases.

Frédéric Pâques, Global Bioenergies' COO declares: "Thanks to the
cooperation of ARD's and Global Bioenergies' teams, the scaling up of our
process in our industrial pilot has been achieved in record time. This is
in line with our fundamental belief that the fermentative production of a
gas facilitates the scaling up efforts. This hypothesis is being confirmed
day after day".

One cylinder filled with liquefied isobutene was then shipped to Arkema's
Pierre Bénite site south of Lyon as part of the BioMA+ project, which is
financed by the French State (Investissements d'Avenir, operated by the
ADEME). The isobutene will be converted into methacrylic acid - a key
component of acrylic paints - at a pilot unit operated by Arkema.

Jean-Luc Dubois, Scientific Director at Arkema declares: "Arkema was
already in contact with Global Bioenergies when its fermentation process
was still in its infancy. The delivery of this first cylinder illustrates
