A method for reusing contaminants comprising the steps of:
- providing waste from a fracturing process;
- providing ash;
- providing a first supply of Portland cement;
- high energy mixing said waste from said fracturing process, said ash, and said Portland cement to create a plurality of agglomerates;
- processing said agglomerates;
- encapsulating said agglomerates:
- providing a final aggregate with said encapsulated agglomerates;
