Waste Classification
Waste Classification in accordance with WM3 is required to determine how soils and other materials arising from site works should be managed, transported and disposed of. Using chemical analysis and a structured assessment process, we classify materials to ensure they are handled lawfully and efficiently.
What this Service Includes
- Review of site information and proposed earthworks
- Development of a sampling and analysis strategy
- Chemical testing by UKAS-accredited laboratories
- WM3 assessment and waste classification
- Determination of hazardous or non-hazardous status
- Identification of appropriate disposal routes
- Duty of care and regulatory compliance support
- Preparation of clear, auditable waste classification reports
Our Approach
Our WM3 assessments follow a structured, evidence-based methodology aligned with current regulatory guidance and best practice.
Our approach includes:
Proportionate sampling strategies aligned with site conditions
Transparent interpretation of laboratory results
Clear justification of waste classifications
Practical advice to support compliant waste management
Regulator-ready reporting and documentation
We work closely with contractors, waste managers and regulators to ensure classifications are robust, defensible and fit for purpose.
Why Waste Classification (WM3) is Essential
Correct waste classification is essential to ensure legal compliance, protect the environment and control project costs. Inaccurate or overly conservative classification can result in unnecessary waste movements, increased disposal costs and regulatory risk.
By providing clear, accurate WM3 classifications, we help projects progress efficiently while meeting environmental and legal obligations.
