inertization
Inertization is the process of rendering reactive constituents inert by immobilizing them in a stable matrix or converting them into inert compounds, thereby reducing reactivity, mobility, and potential biological effects. The term is used in hazardous waste management, soil remediation, and related fields to describe measures that prevent hazardous substances from reacting or moving within the environment.
Common approaches include solidification/stabilization with cementitious materials (S/S), encapsulation in polymers or mineral matrices, and vitrification,
In practice, inertization is used to stabilize heavy metals and organics in hazardous wastes, to treat contaminated
By reducing leachability, volatility, and reactivity, inertization lowers hazard potential, simplifies handling, and can reduce disposal
Long-term performance depends on environmental conditions and matrix stability; not all contaminants are effectively immobilized; there
Effectiveness is assessed with leaching tests and durability assessments; standards and permitted thresholds vary by jurisdiction.
