A pair of biodiesel plants, one in the U.S. and the other in the UK are being upgraded. Biodiesel Magazine reports Austria-based BDI-BioEnergy International AG will upgrade and get back to running an unnamed plant in Atlanta (suspected to be Renewable Energy Group’s currently idled 15 MMgy Atlanta-based biodiesel facility) and beef up the British plant’s (also unnamed) purification capabilities.

BDI stated it has been commissioned to carry out basic engineering assignments at the Atlanta-based biodiesel plant, a prerequisite for successfully implementing its RetroFit Program at the site. “The aim is to modernize the plant, which is out of operation at the moment, in such a way that a profitable restart of production can be guaranteed,” BDI stated.

BDI has also been commissioned by an unnamed British biodiesel manufacturer to implement a biodiesel purification unit. With the help of this optimization unit, the contaminant content of the biodiesel, particularly the residual monoglycerides, will be reduced to a level that is far lower than the relevant limits specified by the strict European biodiesel quality standard. This project will guarantee not only a considerable improvement in quality but also an increase in the output of the biodiesel plant.

The two jobs have a value of about $540,000.
