Advanced Waste Classification: Waste Soils

Develop specialist expertise in the classification of contaminated soils and excavation waste

The classification of waste soils can be one of the most complex areas of waste assessment, requiring a detailed understanding of hazardous waste regulations, laboratory data, and technical guidance. Accurate classification is essential for ensuring legal compliance, protecting the environment, and identifying the most appropriate management route for contaminated materials.

This advanced virtual training programme is designed for professionals who already have a foundation in hazardous waste classification and want to build their expertise in the specific challenges associated with waste soils and excavation materials.

Through practical examples and detailed guidance, you'll develop the skills needed to apply WM3 methodology, interpret laboratory reports, assess contamination risks, and confidently classify waste soils in line with current regulatory requirements.
