UC Berkeley team develops 3D printing with light: Computed Axial Lithography

Green Car Congress

In brief, it uses light to transform gooey liquids into complex solid objects in only a matter of minutes. We demonstrated concurrent printing of all points within a three-dimensional object by illuminating a rotating volume of photosensitive material with a dynamically evolving light pattern. We print features as small as 0.3

SGH2 building largest green hydrogen production facility in California; gasification of waste into H2

Green Car Congress

The plant will feature SGH2’s technology, which will gasify recycled mixed paper waste to produce green hydrogen that reduces carbon emissions by two to three times more than green hydrogen produced using electrolysis and renewable energy, and is five to seven times cheaper. The facility will process 42,000 tons of recycled waste annually.

UCalgary, Rice team uses flash joule heating to manufacture graphene from petroleum waste

Green Car Congress

Because the FJH process is a resistive/ohmic heating process that requires the source material to be electrically conductive, and because asphaltene is a poor conductor, the researchers added a minimal amount [20 weight % (wt %)] of conductive carbon black (CB) to the raw asphaltene powder.

Fulcrum to build second waste-to-fuels plant in Gary, Indiana

Green Car Congress

Fulcrum BioEnergy has selected Gary, Indiana as the location of its Centerpoint BioFuels Plant, which will convert municipal solid waste (MSW) into low-carbon, renewable transportation fuel. Once operational, the Centerpoint plant will divert and process approximately 700,000 tons of waste from the Greater Chicago area.
