Giant Miscanthus 101

Miscanthus x giganteusPerennial Energy Grass,Yielding 20+ Tons/Acre

Giant Miscanthus

• The best crop in the SE for growth of cellulosic material

• Many benefits:– Environmental– High Yield & Profit Potential– USDA Incentives & Cost Sharing (BCAP)– Low Inputs & Production Costs– Care-free Growth

• Giant miscanthus identified as a C4 perennial crop Giant miscanthus identified as a C4 perennial crop with huge biomass potential: with huge biomass potential: up to 25 tons/acre/yr, up to 25 tons/acre/yr, dependent upon:dependent upon:

Giant Miscanthus:

7

Miscanthus is not switchgrass.

•Developed by Dr. Brian Baldwin at MSU, through 12 years of biomass crop study and selection for superior traits.

•The only variety MEANT FOR the Southeast.

•Freedom is the only University-released, named, certified strain of giant miscanthus.

“We see a lot of potential in Freedom giant miscanthus --it’s the most promising of the hundreds of miscanthus cultivars we’ve evaluated over the years, and it’s light years ahead of any of the other grasses.”

--Dr. Brian Baldwin, MSU

Scaling-Up: Our Growth Model

Efforts Going Forward:

• 500+ acres of Foundation planted• Demo plots in 10 states

– Monitor, research growth & yields– Learn best approach for each region

• Ongoing Research with MSU

• 2011: We can plant 20-30,000 acres from rhizomes

• 2012+: Exponential growth in acreage
