Mascoma: Frontier

Biorefinery Project

This project involves the

construction and operation

of a biorefinery that

produces ethanol and other

produce 20 million gallons per year of

denatured ethanol from approximately

700 dry metric tons per day of cellulosic

materials, primarily renewable woody

biomass.

More information is available at:

The feedstock for the facility would

consist of hardwood pulpwood obtained

from within a 150-mile radius of the

Michigan site. Feedstock would be

purchased through local timber

suppliers under contract with the

biorefinery or from additional

commercially viable sources as

available.

Mascoma’s proprietary Consolidated

Bioprocessing, which combines

enzymatic hydrolysis to sugars and

simultaneous fermentation to ethanol in

one step. The ethanol/water mixtures

would be sent to distillation and

dehydration for final product

purification. Lignin residues would be

recovered from the distillation step,

dewatered, and used on-site in a solid

In order to finalize the design of the

Frontier facility, intensive piloting work

is being conducted at a Mascoma

facility in Rome, New York. Extensive

operation and analyses at 1,000 and

5,000 gallon scales have enabled a

financeable engineering design of the

final facility at Kinross.
