Lifecycle Study Finds Algae as Bioenergy Feedstock Has Higher Environmental Impacts than Conventional Crops in Energy Use, GHG Emissions, and Water Use; The Importance of Using Waste Streams

Green Car Congress

Terrestrial bioenergy feedstock crops such as switchgrass, canola and corn have lower environmental lifecycle impacts than algae in energy use, greenhouse gas emissions, and water regardless of cultivation location, according to a new lifecycle assessment by researchers at the University of Virginia. 0.4 ± 0.05. 1.8 ± 0.58. 3.3 ± 0.86.

Novozymes introduces its latest enzyme technology for cellulosic biofuels; performs 1.5x better than predecessor

Green Car Congress

Fiberight will open a small-scale plant in Lawrenceville, Virginia, this year, and a plant producing 6 million gallons per year in Blairstown, Iowa, in 2013. Both plants will convert municipal solid waste into biofuel. The numbers would be even higher if biomass from forestry residues, household waste, and energy crops were included.

Advances in the conversion efficiency of thermoelectric materials

Green Car Congress

A collaboration including researchers from Boston College, MIT, the University of Virginia and Clemson University have achieved a peak ZT (thermoelectric figure of merit) of 0.8 for the materials and possibly good enough for consideration for waste heat recovery in automotive exhaust systems. The study by Biswas et al. Biswas et al.
