Energy Costs – Pimentel’s Study It looks like this says corn is energy positive, but the study officially concluded energy negative gal/hectare * 78,789.8 Btu / gal = 62,440,916 Btu / hectare

Ethanol and Commodity Costs

Conclusion / Response Corn ethanol is not sustainable. “The subsidies for a gallon of ethanol are 60 times greater than the subsidies for a gallon of gasoline.” - Sugar ethanol is the future. “The [sugar] ethanol industry in Brazil is more than 30 year-old and …is no longer subsidized.” -

Questions? BUTANOL and PROPANOL? SYNTEC TO DEVELOP CATALYSTS TO PRODUCE BUTANOL AND PROPANOL FROM BIOMASS AND MSW. Vancouver, Canada - 20th November 20th, Syntec Biofuel Inc (OTC.B.B. “SYBF') announced today it is launching a research program to develop catalysts and processes to produce Bio-butanol and Bio-propanol from biomass. This new R&D initiative is projected to be a 3 year program and will run in parallel with Syntec's catalyst development. The company will be seeking strategic financial partners to support the estimated costs of US$2,500,000.
