What constitutes "reactive waste"?

Reactive waste is defined as waste that is chemically unstable and has the potential to react violently under certain conditions, such as in the presence of water. When such a waste comes into contact with water, it may produce toxic fumes, heat, or even result in explosions. This characteristic makes reactive waste particularly hazardous and requires special handling procedures to mitigate the risks associated with its reactivity.

On the other hand, options suggesting that waste can be easily recycled, is non-toxic, or can be safely incinerated do not align with the definition of reactive waste. These options imply a level of safety and stability that is contrary to the inherently dangerous nature of reactive materials. Therefore, the most accurate representation of reactive waste is the one that highlights its violent reactions, particularly with water.
