U.S. DOE to provide $33.8 million to support enzyme development for cellulosic biofuels
The U.S. Department of Energy (DOE) today announced a Funding Opportunity Announcement (FOA) that will make available up to $33.8 (€24.7) million to support the development of commercially viable enzymes - a key step to enabling bio-based production of clean, renewable biofuels such as cellulosic ethanol. The announcement comes after the DOE awarded $385 (€282) million to six cellulosic ethanol projects earlier this year (previous post), part of a US$1.2 billion (€907 million) investment in biorefineries.
This latest FOA is focused on the development of hydrolytic enzymes and enzyme system preparations that can effectively saccharify pretreated lignocellulosics to produce fermentable sugars under process relevant conditions. The enzymes or enzyme systems must be able to survive a wide range of environmental conditions and be stable to denaturing conditions typically found in lignocellulosic processing.
DOE expects that applicants will be willing and able to take the enzyme or enzyme systems to a commercial scale and have a sound business strategy to license and market them. For the purposes of this FOA, 'commercialization' will be defined as the transition from research to routine operational application. This implies the orderly sequence and implementation of actions necessary to achieve market entry and general market competitiveness of the enzymatic systems.

This biofuels effort focuses on production from non-food materials and agricultural waste – such as corn stover, switchgrass, and prairie grass. This FOA focuses specifically on systems to hydrolyze and saccharify cellulosic biomass feedstocks. Saccharification enables the biorefining process by breaking down pretreated cellulosic material into more simple sugars, allowing them to be further processed through fermentation and ultimately turned into biofuels such as ethanol. Enzymes developed under this FOA must prove durable and effective in process-relevant conditions.
As part of the President Bush's "Twenty in Ten Plan", DOE is pursuing a long-term strategy to support increased availability and cost-effective use of renewable and alternative fuels. Twenty in Ten seeks to displace 20 percent of U.S. gasoline usage by 2017 through diversification of clean energy sources and increased vehicle efficiency.

These enzyme projects will serve as catalysts to the commercial-scale viability of cellulosic ethanol, a clean source of energy to help meet President Bush’s goal of reducing our reliance on oil. Ethanol from new feed stocks will not only give America more efficient fuel options to help transform our transportation sector, but increasing its use will help reduce greenhouse gas emissions. - Andy Karsner, DOE Assistant SecretaryWith a minimum 50 percent industry cost-share, the funding will total nearly $68 million to further enzyme commercialization efforts. By harnessing the power of enzymes, which are responsible for many of the biochemical processes in nature, biorefineries can more efficiently use cellulosic (non-food) feedstocks for biofuels production. The funding thus aims to further reduce costs of enzyme system preparations in process-relevant conditions.Since 2000, DOE enzyme development advancements have yielded thirty-fold cost reductions mainly on enzyme production:

Great post!
If the economics don't work, recycling efforts won't either.
As our little contribution to make this economics of recycling more appealing, http://LivePaths.com blogs about people and companies that make money selling recycled or reused items, provide green services or help us reduce our dependency on non renewable resources.
