Purdue study projects that under likely adoption rates, use of biojet fuel alone will not meet aviation emissions reduction targets for 2050; the need to go above 50% blends

A study by a team from Purdue University has found that, at what it determined as likely adoption rates, the use of drop-in biojet fuel (produced from US feedstocks) at up to a 50:50 blend with petrojet fuel alone would not be sufficient to achieve the aviation emissions reduction target of 50% below 2005 levels by 2050.

Ford expands program for measuring suppliers’ carbon footprint

Read the full post at Green Car Congress.

Ford Motor Company has more than tripled the size of its program to understand and measure suppliers’ carbon footprint. Ford is surveying the energy use and carbon emissions of 128 global suppliers, accounting for nearly 60% of the company’s $65 billion in annual purchases. The new group is an expansion of last year’s survey population, which included 35 top suppliers. It includes companies that supply vehicle production parts and components, information technology and logistics services.

U of Minnesota team develops zeolite nanosheets; resulting molecular sieve membranes could make fuel and plastics production more energy-efficient and cost-effective

After more than a decade of research, a University of Minnesota team of researchers has devised a means for developing free-standing, highly crystalline zeolite nanosheets that could make the production of gasoline, plastics and various chemicals more cost-effective and energy-efficient.

Biodiesel club fuels sustainable campus

Read the full story in the University of Portland Beacon.

The Biodiesel Club is turning rice oil into fuel to create a more sustainable future at the University of Portland.

The club uses the rice oil waste from The Commons, which the University would otherwise pay an outside company – such as Oregon Waste – to haul away, and converts it into biodiesel for various uses on campus. For example, Physical Plant would benefit from the converted oil by supplying its mowers with the biodiesel.

Cooking-oil theft: Arlington police charge two with increasingly common crime

Read the full story in the Washington Post.

For months, used cooking oil has been disappearing from containers behind Washington area restaurants. Thieves have been siphoning tens of thousands of gallons a month and reselling it, authorities say.

Arlington County police last week arrested two men at Ballston Common Mall they say were trying just such a scheme.
