BUENOS AIRES (Reuters) – Argentina’s government is negotiating a plan to reduce diesel imports by making energy companies blend more of the fuel with soy-based biodiesel within the next year, industry sources said on Wednesday.

A new law requiring all diesel to be mixed with 5 percent of the plant-based fuel came into force earlier this year in the South American country, the fourth-biggest global biodiesel producer and top supplier of soybean oil. Leer más »

One of the most heated environmental debates concerns biofuels. Using biofuels is nothing new and, in fact, diesel cars were originally designed to run off of peanut oil, but diesel fuel ended up being cheaper than peanut oil.

Now with pollution and the very real threat of drying oil wells, car manufacturers and scientists are once again turning to biodiesel fuels in order to solve this problem.

Biodiesel fuel is generally made from vegetable oils (soy being the most popular) or animal fat, either way it is biodegradeable. Leer más »

Yields of biodiesel from oilseed crops such as safflower could be increased by up to 24 percent using a new process developed by chemists at UC Davis.

The method converts both plant oils and carbohydrates into biodiesel in a single process, and should also improve the performance characteristics of biodiesel, especially in cold weather. Leer más »

Engineers from the University of Cincinnati devise a foam that captures energy and removes excess carbon dioxide from the air — thanks to semi-tropical frogs.By: Wendy Beckman.

For decades, farmers have been trying to find ways to get more energy out of the sun.

In natural photosynthesis, plants take in solar energy and carbon dioxide and then convert it to oxygen and sugars. The oxygen is released to the air and the sugars are dispersed throughout the plant — like that sweet corn we look for in the summer. Unfortunately, the allocation of light energy into products we use is not as efficient as we would like. Now engineering researchers at the University of Cincinnati are doing something about that.

SAO PAULO, March 22 (Reuters) – Braskem (BRKM5.SA), Latin America’s largest petrochemicals company, may open a second factory to produce polyethylene from sugar cane-based ethanol, once a first plant starts up around October, a project manager at the firm said on Monday.

Braskem expects to become the first commercial-scale producer of polyethylene made from a renewable source when a plant in Brazil begins producing the building block resin used in plastics at the Triunfo plant, said Leonora Novaes, Braskem’s commercial head for green polyethylene. Leer más »

Global Biodiesel Market Expected to Produce 45,291 million liters by 2020.

Production increased from 959 million liters in 2001 to 15,760 million liters in 2009, at a CAGR of 41.9%. Supported by governments to increase energy independence and meet the rising energy demand the biodiesel market is expected to produce 45,291 million liters of biodiesel in 2020, representing a CAGR of 10.1% during 2009 to 2020. Europe is the leading biodiesel market with a production share of 49.8% followed by the Americas with a production share of 32.8% and Asia Pacific with a share of 4.4% in 2009. Leer más »

 What if space held the key to producing alternative energy crops on Earth? That’s what researchers are hoping to find in a new experiment on the International Space Station.

The experiment, National Lab Pathfinder-Cells 3, is aimed at learning whether microgravity can help jatropha curcas plant cells grow faster to produce biofuel, or renewable fuel derived from biological matter. Jatropha is known to produce high quality oil that can be converted into an alternative energy fuel, or biofuel(biodiesel). Leer más »

BA says the plant will reduce the amount of waste sent to landfill.

British Airways has struck a deal to build the first plant in Europe to produce jet fuel from waste matter.

Some 500,000 tonnes of waste will be used by the UK facility each year to produce 16 million gallons of fuel.

Construction of the plant in east London will start within two years. It is set to produce fuel from 2014, creating up to 1,200 jobs. Leer más »

A research project will make jet fuel without wasting fresh water or farmland.

A project in the Middle East aims to make jet fuel from saltwater-tolerant crops grown in the desert. Researchers at the Masdar Institute in the United Arab Emirates are starting a two-square-kilometer demonstration farm that will combine fish and shrimp farming with the cultivation of mangrove trees and salicornia, a plant with oil-rich seeds that can be converted into fuel.

BUENOS AIRES – The Argentine government said Friday that, in compliance with a 2006 law, all diesel fuel in the country must contain at least a 5 percent of biodiesel.

“Biodiesel will be incorporated into the energy matrix, initially accounting for 5 percent of domestic demand, that is 742 million liters (196 million gallons) per year, which is equivalent to the amount of conventional diesel fuel imported by Argentina in 2008,” Planning Minister Julio de Vido told a press conference.
