Cellulosic Sugar and Lignin Production Capabilities RFI Responses

Responses to DE-FOA-0001615: Request for Information: Cellulosic Sugar and Lignin Production Capabilities

The mission of the U.S. Department of Energy’s Bioenergy Technologies Office (BETO) is to develop and demonstrate transformative and revolutionary, sustainable bioenergy technologies for a prosperous nation. To facilitate this goal, BETO supports research, development, and demonstration efforts that advance technologies to produce both (a) drop-in biofuels that can replace gasoline, diesel and jet fuel and (b) biomass-based products and chemicals that can compete with their petroleum-derived counterparts and enable biofuels deployment. Many conversion technologies that produce these biofuels or bioproducts utilize cellulosic sugars or lignin in their process. As a result, both lignocellulosic sugars and lignin have become necessary intermediates for advancing research towards economically producing biofuels and bioproducts.

The purpose of this request for information (RFI) was to develop a list of suppliers who are willing and able to produce and sell cellulosic sugar and/or lignin for use by the research community. BETO believes that its funding recipients, as well as the general research community, will use this information to determine what resources are available.

DISCLAIMERS OF LIABILITY AND ENDORSEMENT: The tables below do not constitute an all-inclusive list of cellulosic sugar and lignin suppliers, but rather reflect only submissions in response to the Request for Information (RFI) dated July 20, 2016, issued by the U.S. Department of Energy’s Bioenergy Technologies Office, and information subsequently received from suppliers in accordance with the requirements of Additional Submissions below. Neither the United States nor the U.S. Department of Energy, nor any of their employees, makes any warranty, express or implied, including warranties of merchantability and fitness for a particular purpose, or assumes any legal liability or responsibility for the accuracy, completeness, or usefulness of any information, apparatus, product, or process disclosed, or represents that its use would not infringe privately owned rights. Moreover, references in the tables to any organization, entity, commercial product, process, or service by trade name, trademark, manufacturer, or otherwise, does not constitute or imply its endorsement, recommendation, or favor by the United States Government or the U.S. Department of Energy.

ADDITIONAL SUBMISSIONS: BETO invites additional submissions to the RFI from cellulosic sugar and lignin suppliers and will periodically update the tables. Please submit additional submissions to this RFI to sugarandlignin@ee.doe.gov. However, please read the full RFI, to see the full list of questions/information requested.
