Brewery waste becomes scientific fodder for producing liquid biofuels

February 28, 2011 2:56 am | News | Comments

The new tagline could be: this microbe's for you. Cornell scientists took regular samples of bioreactor sludge from nine Budweiser brewing facilities over the course of a year and, using genome sequencing software, they analyzed gene sequences of the microbes in the sludge. Budweiser already harnesses these microbes for methane; researchers hope to re-purpose them for other fuels.

Enzyme cocktail could help eliminate a step in biofuel process

February 25, 2011 4:08 am | News | Comments

Conversion of biomass to fuel requires several steps: chemical pretreatment to break up the biomass, such as with dilute sulfuric acid; detoxification to remove the toxic chemicals; then microbial fermentation to convert the soluble sugars to fuels. Virginia Tech researchers have discovered an enzyme mixture that works in the presence of the toxin-infused liquid biomass, meaning that the detoxification step is unnecessary.


Turning old oil into new mileage

February 24, 2011 3:10 am | by David L. Chandler, MIT News Office | News | Comments

The estimated half-million garbage pickers in Brazil, known as catadores, turn trash into gold: they sort out recyclable items in the country’s dumps, then sell their findings to recycling companies. But the process of getting the recyclables to their final destination involves fleets of fuel-consuming vehicles. Now—with help from some MIT students—the catadores have a less-expensive and environmentally friendly fuel option: recycled cooking oil.

Researchers develop new technology for more efficient solar cells

February 22, 2011 3:19 am | News | Comments

The sun provides more than enough energy for all our needs, if only we could harness it cheaply and efficiently. Solar energy could provide a clean alternative to fossil fuels, but the high cost of solar cells has been a major barrier to their widespread use. Stanford researchers have found that adding a single layer of organic molecules to a solar cell can increase its efficiency three-fold and could lead to cheaper, more efficient solar panels.

Green chemistry: The route towards zero-waste production

February 18, 2011 3:51 am | News | Comments

Novel green chemical technologies will play a key role helping society move towards the elimination of waste while offering a wider range of products from biorefineries, according to a Univ. of York scientist.

Converting algae grown in wastewater to biodiesel

February 18, 2011 3:28 am | News | Comments

Researchers at Rochester Institute of Technology are developing biodiesel from microalgae grown in wastewater. The project is doubly “green” because algae consume nitrates and phosphates and reduce bacteria and toxins in the water. The end result: clean wastewater and stock for a promising biofuel.

Magma power for geothermal energy?

February 18, 2011 3:20 am | News | Comments

When a team of scientists drilling near an Icelandic volcano hit magma in 2009, they had to abandon their planned experiments on geothermal energy. But the mishap could point the way to an alternative source of geothermal power.


Hydrogen cartridges fuel laptops and phones

February 18, 2011 3:01 am | News | Comments
