HSW

Hazardous Solid Waste

Hazardous Solid Waste (HSW) refers to a waste classification, detailed in the NSW EPA’s Waste Classification Guidelines, where the waste materials leaving a site pose a significant risk to human health or the environment due to their chemical, physical, or biological properties. These materials require specialised handling, transport, and disposal in accordance with strict regulatory controls.

Key Components

• Hazardous Characteristics: May be toxic, corrosive, flammable, reactive, or otherwise harmful.
• Common Sources: Includes contaminated soils, asbestos-containing materials, chemical residues, heavy metals, and industrial by-products.
• Handling & Transport: Must be managed by licensed contractors using approved containment and transport methods.
• Regulatory Compliance: Subject to strict classification, tracking, and disposal requirements under environmental legislation.

Proper identification and management of HSW are critical to protecting human health, preventing environmental contamination, and ensuring full regulatory compliance on construction and remediation projects.
