Comet Biorefining, a London company, is a leader in the field of biomass conversion and biomass pretreatment. Comet's knowledge and experience in the pretreatment of biomass spans numerous raw materials and many end use applications. This sustainability company has announced a new sugar technology to digest a wide range of cellulosic biomass and convert it into ethanol fuels.
This cellulosic ethanol technology employs cellulosic ethanol feedstock such as wood chips, switch grass and corn cobs to produce cellulosic sugars and then convert it into fuels. For the production of these cheap pre-treatment methods were used and these sugars were shipped to the biorefineries wherein they are converted into ethanol.
The greatest advantage with this cellulosic sugar is the fact that if remains stable for a long-time even after pre-treatment due to its high –density. Hence, this advantage makes it possible to be shipped or transported to biorefineries in farther places as well.
This breakthrough will definitely reduce the capital and operating costs of the biofuel companies , whooonly processes the cellulosic sugar for bioethanol . This will further help them to focus more on developing better enzyme technology to carry out the steps to make biofuel from the broken down sugar.
Comet Biorefining has demonstrated this unique technology at pilot scale and estimates that cellulosic sugar can be produced for as low as 7 cents per pound based on laboratory testing. Comet Biorefining plans to build a demonstration facility in 2010 and partner with biofuels technology developers to provide them with cellulosic sugar for their processes. Comet Biorefining's goal is to license its Cellulosic Sugar Technology worldwide.
Pilot and demonstration plants have shown promising results, and the London company believes that even small pretreatment plants can provide cellulosic sugars for large biofuel industries thereby making their biofuel production economically viable.
