Renewably produce biofuels

New Technology for Energy Needs: Cost-Effective, Renewable Biofuels Amyris Biotechnologies is developing a large-scale fermentation process to renewably produce biofuels. Amyris is developing a gasoline substitute that contains more energy than ethanol, will result in lower cost and less polluting … Continue reading

What is Biomass Gasification?

Biomass gasification is different from cellulosic ethanol in at least two major respects. First of all, it is a combustion process, not a fermentation process. As a combustion process, it can be self-sustaining once the combustion is initiated. It does … Continue reading

$1 Ethanol

Coskata, a startup that says it can make ethanol from almost any carbon-rich source—including old tires—for less than $1 a gallon. That’s about half as expensive as making gasoline, and much cheaper than other next-generation biofuels. General Motors bought the … Continue reading

SUGAR FEEDSTOCKS

Fermentation involves microorganisms that use the fermentable sugars for food and in the process produces ethanol and other byproducts. These microorganisms can typically use the 6-carbon sugars, one of the most common being glucose. Therefore, biomass materials containing high levels … Continue reading

CELLULOSIC FEEDSTOCKS

Like sugar materials, starchy materials are also in the human food chain and are thus expensive. Fortunately, a third alternative exists—cellulosic materials. Examples of cellulosic materials are paper, cardboard, wood, and other fibrous plant material. Cellulosic resources are in general … Continue reading

ETHANOL-FROM-CELLULOSE

ETHANOL-FROM-CELLULOSE In times of fuel shortages, fermentation ethanol has been commercially manufactured in the US from cellulosic biomass feedstocks using acid hydrolysis techniques. Currently, some countries in locations with higher ethanol and fuel prices, are producing ethanol from cellulosic feedstocks. … Continue reading

THERMOCHEMICAL PROCESSES

There are two ethanol production processes that currently employ thermochemical reactions in their processes. The first system is actually a hybrid thermochemical and biological system. An example is a process under development by Bioengineering Resources in Fayetteville, Arkansas. Biomass materials … Continue reading

The Advantages of Cellulosic Feedstocks

Cellulosic feedstocks have many advantages over using corn to produce ethanol. Because cellulosic crops are not used for food, there is inherently less price volatility. And because a wide variety of crops can be used, they can be grown in … Continue reading
