Green Biologics shuts down its Minnesota biorefinery
Type of post: NEWS.
Bad news from the biobased chemical sector. Green Biologics Ltd (GBL) has announced through a succinct press release on its
website that it is shutting down its Little Falls (Minnesota) biorefinery: “After
a detailed review, the Board of Green Biologics Limited (GBL) has concluded
that it is not possible to secure funding to enable it to continue with its
plan to build up sales and production levels of renewable butanol and acetone
at the Group’s Little Falls, Minnesota plant to the point of cash break-even.
Accordingly, given this withdrawal of financial support, the Board and
Managements of its subsidiary companies, Green Biologics, Inc., and Central
Minnesota Renewables LLC have commenced an orderly closure of operations and
wind-down of those corporations for and subject to any actions by their
creditors. In the short term the Board of GBL will be considering strategic
options for the future of GBL.”.

Background of the plant
GBL is a renewable chemicals company based in
Abingdon (England) with a wholly owned US operating company, Green Biologics
Inc., based in Gahanna (Ohio). GBL’s Clostridium fermentation platform converts
a wide range of sustainable feedstocks into n-butanol and acetone. This platform
is fruit of the development of the original ABE (Acetone – Butanol – Ethanol)
fermentation process.
GBL started the construction of its biobased
n-butanol and acetone manufacturing facility in Little Falls on September 1st,
2015. The existing manufacturing site, formerly known as The Central MN Ethanol
Cooperative (CMEC), was acquired by GBL in December 2014 and re-named Central
MN Renewables (CMR). At the end of 2016, GBL launched the first shipments of
biobutanol and acetone from its Little Falls biorefinery.
