GLOBAL BIOENERGIES reports first isobutene production from waste biomass
March 03 2015 - 2:08AM
Global Bioenergies (Alternext Paris - ALGBE) announces today
having produced "second generation" isobutene, in a push to
diversify accessible feedstock towards cheaper resources.
As a first step in its pioneering journey to
manufacture bio-sourced isobutene, Global Bioenergies has been
using first generation feedstock, such as wheat-derived glucose, to
set-up and optimize its bio-isobutene process. However, the process
was designed to be versatile in terms of feedstock. With the right
technical adaptations, it would indeed be well suited to the usage
of non-edible resources - widely defined as "second generation" -
such as wheat straw, corn stover, sugar cane bagasse or even wood
chips.
Various companies are presently debottlenecking
the conversion of second generation materials into fermentable
sugars. These technologies have now matured to commercial scale,
with five plants having started operations in the last 24 months.
This industry ultimately has the potential to provide fermentation
processes with low-cost sugars derived from abundant resources.
Global Bioenergies has recently established
collaborations with nine companies from three continents developing
the most promising technologies to convert various resources
(straw, bagasse, wood.) into fermentable sugars. Preliminary tests
have resulted in successful second generation isobutene production
at the laboratory scale, with process performances similar to the
ones observed using wheat-derived glucose.
Frédéric Pâques, Chief Operating Officer at
Global Bioenergies comments: "We have now demonstrated
experimentally that our isobutene production process is compatible
with a range of second generation resources. Using
impurity-containing sugar solutions is usually difficult in
classical fermentation processes that lead to liquid compounds,
because the accumulation of such impurities in the culture broth
makes purifying the product more complex. Our process, which is
based on the production of a gaseous product, alleviates these
issues and will allow us to use the cheapest types of
feedstock."
Thomas Buhl, Head of Business development at
Global Bioenergies concludes: "Accessing second generation
feedstocks strengthens the stunning perspective of our isobutene
process to being massively used in the mid-term for the
manufacturing of transportation fuels such as gasoline and jet
fuel."
About GLOBAL BIOENERGIES
Global Bioenergies is one of the few companies
worldwide, and the only one in Europe, that is developing a process
to convert renewable resources into hydrocarbons through
fermentation. The Company initially focused its efforts on the
production of isobutene, one of the most important petrochemical
building blocks that can be converted into fuels, plastics, organic
glass and elastomers. Global Bioenergies continues to improve the
yield of its process and recently announced success with first
testing in its industrial pilot. The company also replicated its
achievement to propylene and butadiene two members of the gaseous
olefins family, key molecules at the heart of petrochemical
industry. Global Bioenergies is listed on Alternext, Euronext Paris
(FR0011052257 - ALGBE).
