GLBRC research review concludes cellulosic biofuels can benefit the environment if managed correctly

Green Car Congress

Nitrogen fertilization can substantially discount the climate and water quality benefits of bioenergy crops if applied in excess of plant need; some high-productivity perennial crops require little if any supplemental N.

Researchers Show New Piezeoelectrochemical Effect Can Scavenge Energy Wastes Such as Noise or Vibration to Generate Hydrogen Via Water Splitting

Green Car Congress

H 2 and O 2 are produced by deforming a ZnO fiber or BaTiO 3 dendrite in water via oxidation-reduction reactions. Materials scientists at the University of Wisconsin-Madison have discovered a phenomenon—the direct conversion of mechanical energy to chemical energy—which they termed the piezoelectrochemical (PZEC) effect.

Study finds that optimized integrated catalytic processing of biomass could produce renewable jet fuel with selling price as low as $2.88/gallon

Green Car Congress

A team from seven US universities and the Korea Institue of Science and Technology, led by George Huber, Professor of Chemical and Biological Engineering at the University of Wisconsin-Madison, has developed an integrated catalytic process for the conversion of whole biomass into drop-in aviation fuels with maximal carbon yields. per gallon.

Study Concludes That Use of Cellulosic Feedstocks to Meet US Biofuel Requirements Will Still Likely Result in Expansion of the Gulf Dead Zone

Nitrogen and phosphorus from agricultural fertilizer have been found to promote excess growth of algae in water bodies—a problem that’s common across North America and in many areas of the world. In some cases, decomposition of algae consumes much of the oxygen in the water. Earlier post.). Christine Costello, W. Landis and H.

They also generate environmental problems from degrading soil to runoff into rivers where they pollute fresh waters and coastal zones. However, there is only one recorded sighting of this bacterium, which grows in toxic environments. Artificial fertilizers are costly and are produced using vast amounts of fossil fuel.
