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.
Together, Lucideon and Nuvia UK have developed the novel geopolymer formulation to enable nuclear waste owners to process problematic wastes into a passive waste matrix that maximizes waste loading and reduces overall waste disposal volumes.
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.
MALLET™ technology can immobilize 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.

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.
