Heritage-Crystal Clean Inc. announced the startup of the second phase of its used oil re-refinery in Indianapolis, Indiana, and the first production of lubricating base oil from the plant. This re-refinery is the second largest in the United States, with the capacity to annually recycle up to 50 million gallons of used oil and produce up to 30 million gallons of lubricating base oil. The project was announced in 2010, initially with an expected startup in the middle of 2012, but the company was able to accelerate the project and finish the construction by the end of 2011.
