FW: oil-bearing diatomaceous earth

Hello Everyone
We conducted a site visit to an aluminum rolling mill recently.  Their major
waste stream of concern was a diatomaceous earth that filters the
lubricating oils used in the rolling process.  The "D.E." is currently
allowed to go to a Subtitle D solid waste landfill.  The company wants to
have it burned at the power plant, but have been unable to because of Air
Quality's PSD concerns.  Do any of you all know of alternative filtration
mechanism that would help the company clean and reuse their oils but not
result in such a heavy disposal burden?
