Bio-Extraction Inc. and BioNex Energy Corp (BEC)
in western Canada have agreed to study, test, and prove the commercial
efficiency of an extraction technology to produce biodiesel more efficient
and have better byproducts.
BEC is a developmental stage company that intends to use cold crushing
technology in its plant as a first-stage process for removal of oil from canola
and other high oil-content crops; BioExx would provide the second-stage
The first stage of oil removal will remove approximately 80% of
the oil from the biomass while maintaining a consistently low temperature. In
the second and final stage of oil removal, the process will remove up to 100% of
the remaining oil while at the same time maintaining the protein value
originally contained in the biomass.
On a combined basis, this process
could improve yields of oil volume versus existing oil-removal technologies
while at the same time increasing the residual value of the biomass. In some
cases, BioExx may also be able to isolate the proteins for use as protein
additives in animal or fish feed and eventually for human
100% oil removal
The BioExx technology has the
capability to remove up to 100% of the oil but at a significantly reduced
operating temperature while retaining all of the nutritive content of the spent
The spent biomass resulting from this process can have
substantially higher value because they can be sold as higher quality animal
feeds or other higher value protein applications and products.
technology may therefore have the potential to fundamentally improve the
economics of biodiesel manufacturing operations, while at the same time
mitigating the increasingly prominent "food versus fuel" conflict over global
