What are the NSW waste classification guidelines?

The NSW Waste Classification Guidelines, issued by the NSW Environment Protection Authority (EPA), provide a framework for identifying and managing different types of waste to ensure they’re handled, transported, and disposed of safely and legally. The guidelines classify waste into six categories: special waste, liquid waste, hazardous waste, restricted solid waste, general solid waste (putrescible), and general solid waste (non-putrescible). These classifications determine the appropriate treatment, storage, transport, and disposal methods for each type. A key part of the process includes waste sampling and chemical assessment to determine whether the material poses risks to human health or the environment. For construction and remediation projects, complying with these guidelines is essential to avoid penalties and protect the environment.
