Have you noticed the change in the way biofuels have been promoted in North America over the last few months? When biofuels first started to become popular it was all about being better for the environment. Now that corn based ethanol and coal-to-liquids have been shown to be worse for the environment than petrol, diesel or jet fuel the mantra has changed to “energy independence” and “reducing dependence on foreign oil” etc.
This is a worrying trend indeed as it basically says to the world that in general North America, the US in particular, really doesn’t care about the environment. All they care about now is the reduction of oil imports.
One potential shining light in all of this is Canadian company, Syntec Biofuel Inc. (Syntec). Syntec has acquired ethanol catalyst technology which has been developed to convert biomass into ethanol, butanol, methanol and propanol. Biogas and syngas from wood waste, organic waste, corn stover, sugar bagasse, switch grass, poplar etc. is becoming economically viable for some producers so Syntec are starting to test their catalysts in an industrial environment in order to quantify the life of the catalysts prior to commercialization.
Syntec’s development team under the direction of Dr. Caili Su will be working on improving yield to achieve their target of 113 US gallons per ton of biomass. The variable cost per gallon of alcohol on current yield is USD0.48 per gallon which is expected to shrink to USD0.37 per gallon on reaching the targeted yield.
Syntec’s technology is based on thermo-chemical conversion of syngas, produced by gasifying biomass, and passing the gas over the catalysts in a fixed bed reactor. This process is similar to producing methanol which is an established and well known technology.
Michael Jackson, President of Syntec says:
The industry recognizes that production of corn to ethanol has a negative impact on consumer food prices and farm land while cellulosic conversion of waste products are going to spawn the next generation of growth in the Ethanol industry. With oil prices now exceeding $80 a barrel the use of ethanol as a fuel additive is currently one of the few options available to reduce our reliance on imported oil.
The press release makes no mention of the environmental benefits of the process or products. Even the Technology page on their web site bangs on about reducing a country’s dependence on imported oil required for petroleum derived fuels.
Syntec, we would really like to know how much energy your process uses per gallon of ethanol, butanol etc. How much water does it use? What are the waste streams and how they are handled? How truly green is your product when its whole life-cycle is considered.? It’s not all about the money all of the time.

Update (15 Feb 08) – Syntec have responded to the above and the points you raised in comments by providing the following information:
To answer a few of the questions raised by Mr. Hallam and some of the commentors: The waste streams resulting from Syntec’s technology are minimal, the resulting CO2 less than what would have been produced had the material (eg. forestry waste) been left to decompose on its own. Metal contamination is not an issue as the process uses very little water, and what water is used is recycled through the process. You are probably aware of the recent media storm surrounding ethanol produced from agricultural crops (eg. corn, wheat, etc..). None of the environmental or ethical issues raised by the media apply to Syntec’s technology as we only use WASTE materials to produce our biofuel. Our technology is capable of converting virtually any solid or gaseous cellulosic material eg. forestry waste (bark, leaves, chips, dust), agricultural waste (corn stover, bagasse), and even municipal wastes into ethanol. We are proud of our technology and do not believe that food production needs to compete with fuel production.
