The Swedish people take the environment and their need to reduce oil use seriously. That attitude is reflected in their use of flexible-fuel vehicles, which has increased from 717 in 2001 to more than 100,000 today.

Ethanol plants may vary in design, but they all need one thing: piping. There are different types of piping that connect the many processes within the facility, and each offers its own advantages. Although this equipment is essential it isn't without its challenges when it comes to labor, maintenance, safety, education and cost.

As the food-versus-fuel debate rages, ethanol producers are searching for nonfood and food-based waste products to make renewable fuel. This has led researchers to take a closer look at watermelons that don't ripen in time for harvest or fail to make the grade for grocery store produce aisles.

Ethanol plant technicians who are able to avoid unexpected shutdowns are like money in the bank. Instructors at the Biofuels Automation University in Plymouth, Minn., believe that with highly trained technicians and the technology available today, there should be no unscheduled downtime in an ethanol facility.

Bacterial contamination is one of the banes of ethanol production. Producers spend a considerable amount of money on sanitation and antibiotics trying to control bacteria in their fermentation tanks. A new system will not only reduce bacteria in the fermentation tanks, but also prevent re-infection. As a bonus, the new system leaves distillers grains free from antibiotic residues.

One can easily drive through the U.S. Midwest and run across an E85 station before it's time to refuel. There may even be a couple different stations to choose from. Ethanol marketers in the Northeast can only dream about that kind of distribution, but they're working hard to make it a reality.

Whether it's enzymes for degrading cellulose, microbes for fermenting sugars into ethanol or solid particles for the reforming of syngas to ethanol, the development of highly active and selective catalysts for biofuels production will be key to the success of the industry.

Since 2006, Indy Racing League competitors have been using ethanol to fuel their hopes for a checkered flag. Making sure that quality is never sacrificed in the process is the job of PerkinElmer Inc. EPM goes to the Milwaukee Mile to experience the power of Indy racing and to see firsthand what goes into testing the fuel for this high-octane environment.

With the advent of cellulosic ethanol, design/build teams are gearing up for the commercialization of the next generation of biofuels, and at the same time are continuing to be involved in corn-based ethanol, where they built their reputations. EPM talked with some of the big names in the industry to get their view on this challenging transitional period.

With unwavering mettle, John Rivera of Sustainable Power Corp. intends to introduce a biocrude oil product, called Vertroleum, into the global fuel supply chain. Despite its detractors, the company continues to refine what it refers to as the "Rivera Process" at its Texas demonstration facility. Biomass Magazine traveled there to see how the production process works.

The biomass gasifier at Chippewa Valley Ethanol Co. is fuel-flexible by design. Thisrequires a handling system engineered to move feedstocks of varying volumes and densities. Biomass Magazine speaks with Rapat Corp., the engineer of the bulk conveyance system, and equipment vendor Robert White Industries Inc., about the project.

Wood chips are commonly used as a feedstock in the biomass industry-but what processes must waste wood undergo before it is suitable for use? How is contaminated wood treated to meet standards and obey regulations? Biomass Magazine investigates the old and new processes some companies are using to clean and recycle waste wood.

A few years ago, American Crystal Sugar Co. began supplying the University of Florida with sugar beet waste for a research project that, if realized, could change the way the company does business by turning some of its waste into energy. While the project is still in the pilot-plant phase, all signs point toward a successful turnaround from waste product to green energy.
