The advantages of SPC are [11]: (1) it has a greater waste-to-agent ratio than concrete; (2) it has the ability to be remelted and reformed; (3) it is less permeable than concrete; (4) in its final waste form it is devoid of water; and (5) it can be processed at relatively low temperatures. In determining cost and environmental advantages, the volume-reduction factor offered by the sulfur polymer cement is its most redeeming aspect with the high cost of waste disposal. Additionally, the absence of water in the final waste form offers less chemical breakdown, biodegradation, leaching, and gas generation after disposal. However, SPC is new and therefore, continued testing is essential.
