Millennium Petrochemicals, Inc.
The facilitys Permanent Pollution Prevention Planning Team reviewed the generation mechanics of spent aggregate filter media. It was determined the hazardous constituents could be separated from the filter media, returned to the process, and eventually to a by-product stream before the media is removed from the filter vessel. The filter media could then be classified as a TNRCC nonhazardous Class I waste material that was acceptable for use as aggregate in asphalt paving material.
This project eliminates the need to incinerate and landfill 56 tons of hazardous waste.
