Brown Chemists Develop Process to Simplify Waste Vegetable Oil to Biodiesel Process, Chart Progress of Transesterification Reaction

Green Car Congress

Two chemists at Brown University have streamlined the conversion of waste vegetable oil (WVO) into biodiesel, eliminating the need for corrosive chemicals to perform the reactions. Current techniques for the conversion of waste vegetable oil to biodiesel take time, are costly and are inefficient. —Jason Sello.

Chalmers team identifies two main challenges for bio-hydrocarbon fuel production from cheap sources

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have identified two main challenges for renewable biofuel production from cheap sources: lowering the cost of developing microbial cell factories; and establishing more efficient methods for hydrolysis of biomass to sugars for fermentation.

Researchers develop cheaper, greener biofuels processing catalyst using waste metals and bacteria

Green Car Congress

A team from the Prairie Research Institute at the University of Illinois, with colleagues from the University of Birmingham and Aarhus University, have developed a nanosized bio-Pd/C catalyst for upgrading algal bio-oil. For the palladium to do its job, the bio-oil needs to flow past it during processing. —B.K.

Cheap Sensors for Smarter Farmers

Cars That Think

One of the benefits of using print electronics is being able to mass-produce at a low cost, says Gregory Whiting at the University of Colorado, Boulder, one of the principal investigators of the team working on the sensors. With the new, cheap sensors, farmers will be able to collect data on their farms without worrying about the variability.

Univ of Washington team working to make poplar coppice viable cheap, high-volume biofuel feedstock

Green Car Congress

A University of Washington team is trying to make poplar an economically viable biofuel feedstock by testing the production of younger poplar trees that could be harvested more frequently—after only two or three years—instead of the usual 10- to 20-year cycle.
