SULFUR: NEW USES NEEDED

THIS ARTICLE DESCRIBES BRIEFLY THE WORK NOW IN PROGRESS TO DEVELOP NEW USES FOR THE STOCKPILES OF RECOVERED SULFUR FROM VARIOUS AIR-POLLUTION-ABATEMENT PROGRAMS. A GREAT DEAL OF TESTING AND DEVELOPMENT IS GOING FORWARD, ESPECIALLY FOR ROAD-SURFACE AND SUBSURFACE APPLICATIONS. ONE SOURCE OF WASTE AGGREGATE WOULD BE SULFATED LIMESTONE FROM FLUE-GAS SCRUBBING PLANTS. ELEMENTAL SULFUR MAY BE SUBSTITUTED FOR LIMESTONE AGGREGATE IN ASPHALT PAVING MATERIAL UP TO ABOUT 13% OF THE COMPOSITION. INVESTIGATIONS INTO FLYASH FORMULATIONS HAVE LED TO THE LIKELIHOOD OF USING WASTE SULFATE IN "CONCRETE-LIKE" MIXTURES. SULFUR FOAM, AS SUBSURFACE INSULATION, COULD BE USED IN EVEN HIGHER VOLUMES FOR HIGHWAYS. DEVELOPMENT OF A TRAFFIC PAINT, STARTED OVER TEN YEARS AGO, HAS NOT REACHED COMMERCIALIZATION.
