GreenShift Corp. (GERS: OTC/BB) recently shifted its focus to corn oil extraction to serve ethanol producers hungry for a process efficiency. Earlier this year Valcent Products changed its name to Alterrus (ASIUF: OTC/BB) turned to vertical farming. Green Star Products (GSPI: OTC/PK) was already sidelined last year and is now concentrating on new product testing and certifications and is introducing a line of lubricants. PetroSun (PSUD: OTC/PK) claims it has not abandoned its microalgae and macroalgae interests, but its focusing on energy sources that can be a “bridge” to renewable fuels.
OriginOil (OOIL: OTC/BB) is not exactly producing biofuel. However, it has found alternative commercial applications for its technology and expertise. OriginOil has developed an energy production process for cleaning up oil and gas water. OriginOil is marketing its technology to oil and gas operators using hydraulic fracturing. A partner in Japan is also deploying the OriginOil’s algae harvesting technology in a novel process to clean up radioactive materials.
