<p>The process involves stabilizing a tarry waste material using treatment agents including a modified clay and cementitious binding material. The treatment agents are selected based on the waste material to produce a treated material with improved physical and chemical properties. The tarry waste material is either acidic or alkaline in nature and includes a core tar material and contaminants of the core material. The modified clay reacts with the contaminants to neutralize the contaminant and the cementitious binding material binds the contaminants to mitigate physical migration. The modified clay is derived from a smectite clay. The cementitious material is ordinary portland cement, calcium aluminosulfate, rapid setting cement.</p> |
