Global Bioenergies reports first isobutene production from waste biomass
Global Bioenergies announced 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.
