In a recent report, the National Academies concludes that supporting America’s Renewable Fuels Standard requires increased stability in public policy. The report, which can be read here, addresses a wide range of topics and policy priorities. The report highlights the need for policy certainty and public sector support for advanced biofuels. Developing new technology takes [...]

Putting the pieces together for cellulosic commercialization
40% of the sugars found in lignocellulose can be C5 sugars, which are much more difficult to ferment than the C6 fraction. Yet for cellulosic ethanol plants to become economically viable, we need to find a commercial solution to utilize the C5 sugars. Several options are being evaluated within the industry, but pose challenges because [...]

Ethanol Plants: are you getting all the starch out??
Good science means occasionally questioning paradigms. A group of Novozymes scientists recently analyzed comprehensive lab and plant data to put some assumptions about starch conversion in ethanol production to the test. You might be interested in what we learned. . . Question 1: Are typical fermentations complete at drop? In the lab, we measured the [...]

The hidden costs of onsite enzyme production
Looking at the table above clearly shows that a delivered enzyme solution is a much cheaper solution, both in regards to capital costs and enzymes costs, than any type of onsite enzyme production. The numbers are the result of production scenarios we have developed for an average size plant producing 55 million gallons of cellulosic ethanol per [...]

Cellulosic Ethanol & Power Plant Co-Location: Savings in Synergy
We continue to focus on developing solutions to enable the commercialization of cellulosic ethanol. One promising strategy is the co-location of an ethanol facility and a coal-fired power plant. Co-location results in significant economic and environmental benefits for both industries, including feedstock sharing, cost savings, and regulatory compliance. A power plant located with a cellulosic [...]

Cellulosic bioethanol – how to pick the optimal process layout?
Novozymes has weighed the advantages and challenges of how to move forward with the development of cellulosic biofuel technology, and is setting the direction for process technology developed in our R&D labs. In absence of any commercially viable processes, Novozymes has developed a sophisticated model that allows us to see the tradeoffs through process alterations. [...]

Biomass enzyme production
Novozymes is focused on delivering the enzymes needed to convert various cellulose based biomass substrates into simple sugars for further conversion into biofuels. While Novozymes has focused efforts on significantly reducing the amount of enzymes needed, cellulosic substrates still require significantly more enzymes for effective conversion when compared to starch based substrates. The projected volumes [...]
