New system could put dead seaweed to use as a source of power

By - May 6, 2013 2 Pictures
When it’s alive and in the ocean, seaweed serves as a habitat, spawning ground and food source for marine life. Once it gets washed ashore, however, it pretty much just rots. Typically, along beaches in tourist areas, that dead seaweed is simply gathered and taken to a landfill. Now, however, researchers from Spain’s University of Alicante have conceived of a new seaweed-removal system that has less environmental impact, and that allows the seaweed to be used as an energy source.

Researchers engineer microbe to make seaweed a cost-effective source of renewable fuel

By - January 19, 2012 1 Picture
One of the biggest criticisms leveled at biofuels that are derived from crops such as wheat, corn and sugar cane, is that they result in valuable land being taken away from food production. For this reason there are various research efforts underway to turn seaweed into a viable renewable source of biomass. Now a team from Bio Architecture Lab (BAL) claims to have developed a breakthrough technology that makes seaweed a cost-effective source of biomass by engineering a microbe that can extract all the major sugars in seaweed and convert them into renewable fuels and chemicals.

Termite guts could provide a way to produce biofuel from woody biomass

By - July 6, 2011 1 Picture
Ethanol is the most commonly used biofuel worldwide and is made by fermenting the sugar components of plant materials, usually sugar and starch crops such as sugar cane, corn and wheat. The difficulty in accessing the sugars contained in woody biomass, coupled with criticism that the use of food crops for biofuel production has a detrimental effect on the food supply has prompted research into biofuels that can be made from cellulosic biomass, such as trees and grasses. By looking at the digestive system of termites, researchers have now discovered a cocktail of enzymes that unlocks access to the sugars stored within the cells of woody biomass that could help make it a more viable source of biofuels, such as ethanol.

New NASA map shows tropical forest carbon storage

By - June 27, 2011 2 Pictures
A NASA-led research team has created a new map using ground and satellite data that accurately quantifies the amount and location of carbon stored in Earth's tropical trees and forests. Based on data from the early 2000s, the map focuses on 2.5 million hectares of tropical forest in seventy-five countries. Data shows that tropical forests contain 247 billion tons of carbon, and of this carbon stock, almost half is held in Latin American forests. Almost the same carbon stock is stored in sub-Saharan Africa in its entirety, compared with 61 billion tons of carbon stored in Brazilian forests alone. Read More

Researchers use bacteria to produce potential gasoline replacement directly from cellulose

By - March 10, 2011 1 Picture
With the situation in Libya causing a spike in fuel prices worldwide there's some good biofuel-related news out of the U.S. Department of Energy's BioEnergy Science Center (BESC) that could help to reduce many countries' dependence on oil imports. For the first time, BESC researchers have succeeded in producing isobutanol directly from cellulosic plant matter using bacteria. Being a higher grade of alcohol than ethanol, isobutanol holds particular promise as a gasoline replacement as it can be burned in regular car engines with a heat value similar to gasoline. Read More

UBC green energy project gets government cash injection

By - February 28, 2011 3 Pictures
A first-of-its-kind biomass-fueled, heat and power generation system has been developed by a partnership between Nexterra Systems and General Electric, and is heading to the campus of the University of British Columbia (UBC) next year. The Bioenergy Research and Demonstration Project will meet around six percent of the total annual demand for electricity and up to 25 percent of the university's campus requirements for steam. UBC has just announced that the project has secured a substantial federal and provincial cash injection. Read More

Agave shows potential as biofuel feedstock

By - February 24, 2011 1 Picture
Agave is a very hardy, useful plant. It grows in hot, arid conditions, and has found use in the production of beverages, food, and fiber. Now, it looks like it could have yet one more use – a Mexican botanist believes it could be an excellent biofuel feedstock. Not only does it grow quickly, but global climate change shouldn’t adversely affect it, and it doesn’t compete with food crops. Read More

Agricultural discovery could mean more biomass from the same sized field

By - December 31, 2010 1 Picture
Biofuel derived from crops such as switchgrass certainly holds promise, although some critics maintain that such crops use up too much agricultural land – land that could otherwise be used for growing food crops. A genetic discovery announced this Tuesday, however, reportedly allows individual plants to produce more biomass. This means that biofuel crops could have higher yields, without increasing their agricultural footprint. Read More

NEC goes nuts to create new bioplastic

By - August 31, 2010 4 Pictures
NEC has announced the development of a new biomass-based plastic produced by bonding non-edible cellulose with cardanol, a primary component of cashew nut shells. The new bioplastic is said to achieve a level of durability that makes it suitable for use in electronic equipment and boasts a high plant composition ratio of more than 70 per cent. Read More
