Efficient recovery of lithium from spent LiFePO4 batteries via air oxidation–water leaching at room temperature

Green Car Congress

The toxic electrolytes, binder, and other organic chemicals will result in serious environmental pollution if the spent batteries are not properly treated. As the most cheap and green oxidant, air may be suitable as the oxidant to selectively extract lithium from the LFP cathode material in the water leaching process. Hao Jin et al.

Oleophobic hydrophobic magnetic sponge selectively soaks up oil, sparing water and wildlife

Green Car Congress

The OHM (oleophobic hydrophobic magnetic) nanocomposite slurry can be used to coat any cheap, commercially available sponge. The nanostructure coating can be tailored to selectively adsorb (and later desorb) these pollutants. The researchers applied a thin coating of the slurry to the sponge, squeezed out the excess, and let it dry.

RPI team develops method to use paper-making by-product in lithium-sulfur batteries

Green Car Congress

Researchers at Rensselaer Polytechnic Institute (RPI) have now developed a method to use this cheap and abundant waste byproduct to build a components for lithium-sulfur batteries. Initial funding for the research came from the New York State Pollution Prevention Institute (NYSP2I). Lu Li, Liping Huang, Robert J.

Russian researchers develop wasteless joint processing of electric furnace and ladle slag to produce pig iron and clinker

Green Car Congress

For this purpose, borate glass, a cheap waste material that also requires processing, was added to it. Being located within the city limits, they pollute the environment. Recycling of slags and their reuse in production in the form of quality raw materials will help to solve the problem of depletion of mineral resources.

Danish Power Systems sets new record with degradation rate in high-temperature polymer fuel cells

Green Car Congress

Methanol is cheap to produce and it is easy to extract methanol from biological resources. The advantage of using both hydrogen and methanol is that the systems can generate electricity with almost no pollution and on fuels made from biological ‘green’ materials. The Danish Power Systems fuel cell stacks use methanol as fuel.

NYT Op-Ed proposes using US postal service delivery trucks as mobile sensor platforms

Green Car Congress

But what if they were fitted with sensors to collect and transmit information about weather or air pollutants? Data collection wouldn’t require much additional staff or resources; all it would take would be a small, cheap and unobtrusive sensor package mounted on each truck.

Singapores A*Star Awards S$27.5M In Research Grants for Technologies for Sustainable Development

Green Car Congress

The funding from A*STAR’s Science and Engineering Research Council (SERC) will support research teams from A*STAR research institutes and local institutes of higher learning to develop solutions to manage environmental deterioration, pressures on natural resources and climate change brought on by rapid growth and urbanization.
