MALLET™
MIDAR®-Augmented Lower-cost Lower-carbon Encapsulation Technique
MALLET™ is a new, cost-efficient technique for encapsulating Intermediate Level Waste (ILW) which has the potential to revolutionise nuclear waste disposal, offering a flexible range of characteristics and improved performance compared to existing waste solutions.
We have developed the novel geopolymer formulation to enable nuclear waste owners to process problematic wastes into a passive waste matrix that maximises waste loading and reduces overall waste disposal volumes.
MALLET™ offers significant benefits over current immobilisation methods:
- Higher Waste Loading than Portland Cement (OPC) (>70% encapsulated waste)
- Lower disposal costs
- Lower interim storage costs
- Lower carbon emissions than Portland Cement (OPC)
- Simple batch process
- Potential 'pour on solution' for 3m3 boxes
- Potential to enable near-ground disposal
- Potentially retrofittable to existing encapsulation plant
The aim of MALLET™ is to provide a reliable solution to a global challenge known as problematic nuclear wastes, which are those wastes for which safe, efficient, and cost-effective methods for processing are not readily available. Example problematic wastes include contaminated Sludges, Oils, Zeolites and Graphite.
We have successfully demonstrated complete encapsulation of several problematic waste streams, producing a solid, homogenous solution with high compressive strength.
Encapsulated Sludge Simulant
MALLET™ technology can immobilise magnesium hydroxide-based sludges that result from the corrosion of Magnox fuel cans and swarf. The final waste form results in a 70:30 Sludge:MALLET™ end product.

Encapsulated Oil Simulant
We target and encapsulate contaminated and activated oils that are unable to be incinerated. The final waste form results in a 60:40 Oil:MALLET™ end product.

Encapsulated Graphite Simulant
MALLET™ can be used to encapsulate a wide variety of graphite forms that result from the construction of Magnox and AGR reactor cores.
