| Our unique waste encapsulation system transforms active chemical contaminants to inert, non-reactive states for safety in transfer, storage and disposal. Our process securely encapsulates waste materials, providing a significant reduction of leachability potential and permeability. The resultant matrix provides long-term stability because it maintains an alkaline state which is resistant to acidic degradation.
In partnership with Llyon Technologies, we are able to provide a chemically engineered radioactive waste encapsulation system at the molecular, crystalline and physical level for waste disposal. L-TEM™ is comprised of grain-sized materials used as additive products, consisting of alkali and alkaline earth elements. These are combined in a pre-engineered process, which, when hydrated, forms a complex chemical reaction resulting in a stable matrix. The matrix immobilizes and both molecularly and physically encapsulates radiological solids, sludges or other industrial wastes and converts them to monolithic products. Chemically, the process employs pre-sized crystalline cages that are naturally pozzolanic. Contaminate molecules are chemically attracted to these cages and are transformed into an inert, non-reactive state. |
