Bangkok hotel turns rooftop algae into a growth industry

September 24th, 2013

Reuters reports that Bangkok hotel Novotel is spicing up many of its restaurant dishes with spirulina, an edible algae that the hotel is growing in tanks on its roof.

NASA biofuel algae being grown inside floating plastic bags

April 11th, 2012

NASA has developed a system capable of growing large amounts of algae for biofuel production within a network of floating plastic bags, an innovation its developers say could ultimately produce a new fuel source. By pumping wastewater and carbon dioxid…

New Jersey eyes fertilizer restrictions to save Barnegat Bay

October 5th, 2010

Some residents of New Jersey may be taking that “Garden State” nickname a bit too seriously. Bills aimed at limiting fertilizer use are turning up in the state legislature and may end up severely limiting what residents can use, and when and where they can use it. Proponents of the bills say the legislation is needed in the face of overzealous use of fertilizers that ultimately create algae problems in nearby bodies of water. When it rains, excess nutrients pour into streams, lakes and bays, creating aesthetic concerns and gobbling up oxygen aquatic organisms require to survive.

Report says green aviation gets closer to taking flight

September 23rd, 2010

Much progress has been made in recent years in the development of biofuels made from microalgae, animal fat and other non-petroleum-based substances, and they likely will be approved for use in aircraft by the middle of next year, according to a report in the new Aviation Week & Space Technology.

Western Lake Erie facing ‘mother of all blue-green algae counts’

August 3rd, 2010

From Green Right Now Reports
A perfect storm may be brewing in Western Lake Erie.
Combine heavy spring rain, unusually high phosphorus levels in the Maumee and Sandusky rivers, overflows from Detroit and Toledo-area sewage plants and July’s hotter-than-average temperatures, and Erie is looking at one of the worst algae outbreaks in years.

Already, the algae has formed dense mats on calm days, particularly in the Toledo and Port Clinton areas. And the worst is yet to come: The annual peak occurs in early September.

Warmer ocean temperatures blamed for coral bleaching

July 20th, 2010

From Green Right Now Reports

Higher than normal ocean temperatures are wreaking havoc on coral reefs in south east Asia, the Indian Ocean and the Pacific, turning previously color-splashed areas into white wastelands due to a phenomenon known as “coral bleaching.”

“The bleaching is very strong throughout south east Asia and the central Indian Ocean,” Dr. Mark Eakin, coordinator of the National Oceanic and Atmospheric Administration’s Coral Reef Watch, said. “The reports are that it is the worst since 1997/1998. This is a really huge event and we are going to see a lot of corals dying.”

Sustainable biofuels initiative launches in Pacific Northwest

July 12th, 2010

Alaska Airlines, Boeing, Portland International Airport, Seattle-Tacoma International Airport, Spokane International Airport and Washington State University today announced a strategic initiative to promote aviation biofuel development in the Pacific Northwest. The first regional assessment of its kind in the U.S., the “Sustainable Aviation Fuels Northwest” project will look at biomass options within a four-state area as possible sources for creating renewable jet fuel.

Great Lakes Center Study confirms Lake Erie is still sick

July 1st, 2010

A new study from Buffalo State College has found that, despite meeting targets outlined in the Clean Water Act of 1972, Lake Erie remains fundamentally unhealthy. The Nearshore and Offshore Lake Erie Nutrient Study, which concludes this month, followed a year of research headed by principal investigator Chris Pennuto, a research scientist with the Great Lakes Center and professor of biology. The fundamental question of the study was, “Why didn’t Lake Erie’s health improve as expected when the amount of phosphorus discharged into the lake decreased?”

When green is bad

October 1st, 2009

By Barbara Kessler

This summer as I flew over Minneapolis, I looked down fondly at the chain of lakes that beautifies this tidy, progressive city. My second hometown.

I noticed the surrounding land was lush and green. And so were many of the lakes. Wait a minute: The lakes themselves were more green than blue, ringed in pea-soup of algae that was closing in fast on the open water at the middle. This algae-green, sickly green mess set off alarm bells.

I suspected that all those lake-dwellers residing on their hard-fought real estate were sullying the waters by collectively dumping tons of fertilizer on their neat green lawns, which created a super-rich, even toxic runoff. This was hugely ironic, because these striving homeowners had moved there so they could boat, swim and engage in the state sport, fishing fer walleye. Yet their pursuit of the picture-perfect lake house retreat was poisoning the natural environment.

Fertilizers expected to create large 2009 dead zone in Gulf of Mexico

June 19th, 2009

FROM GREEN RIGHT NOW REPORTS:

The dead zone in the Gulf of Mexico is expected to grow this year to between 7,400 and 8,400 square miles, a size roughly equivalent to the state of New Jersey, according to researchers at the University of Michigan.

That means the zone will be among the top three largest on record; the largest oxygen-starved zone reached 8,484 square miles in 2002.

Continental biofuel flight cut greenhouse gas emissions

June 18th, 2009

By Ashley Phillips
Green Right Now

The friendly skies are getting cleaner thanks to efforts made by Continental Airlines in partnership with Boeing, GE Aviation/CFM International, and Honeywell’s UOP. In early January of this year, Continental Airlines conducted the first biofuel demonstration flight by a commercial carrier in North American. Wednesday, Continental Airlines announced their analysis of this flight in a statement.

The 90-minute test flight, taking off from, and then returning to, Houston, successfully completed many necessary flight operations. Engine 1 operated on 100% jet fuel, while Engine 2 of the Boeing 737-800 operated on a blend of 50% jet fuel and 50% biofuel. The biofuel was made from a combination of algae and jatropha plants, which do not impact food harvests, water resources or contribute to deforestation.

Algae fuel start-up Solazyme turning out auto-ready ‘crude’

March 4th, 2009

By Catherine Girardeau
Green Right Now

SAN FRANCISCO — You’ve probably heard of wheels powered by biodiesel, favored by indie rock bands, gardeners, and other greenies who want to save the world, one tank of used cooking oil at a time. These veggie-fuel fanatics can pull their trucks up to the local burger joint and haul away excess deep-fryer fat, which they take home and convert to usable fuel. But did you know scientists in university research labs and start up companies are using precision, high-tech gene splicing technology to figure out how to mass-produce biofuel from pond scum?

One such algae pioneer is Harrison Dillon, president and chief technical officer of South San Francisco renewable energy startup company Solazyme, Inc. Dillon, a PhD geneticist with training in patent law on the side, is leading his team of highly-skilled technicians to discover, and create, conditions under which algae will produce oil for food, cosmetics and fuel.

The first stop on my Solazyme tour was the parking lot for a ride in the company’s biodiesel-powered Jeep.
