What is Restricted Solid Waste (RSW)?

Restricted Solid Waste (RSW) refers to waste that contains hazardous substances at concentrations exceeding those permitted in General Solid Waste but not high enough to classify it as Hazardous Waste. In NSW, RSW must be assessed and managed carefully under the NSW Waste Classification Guidelines due to its potential risks to human health and the environment.

Common examples include contaminated soils, certain industrial residues, and waste with detectable levels of heavy metals, hydrocarbons, or pesticides. RSW cannot be disposed of at a standard landfill—only facilities licensed to accept restricted waste can handle it. Proper classification and documentation (including chemical analysis) are critical before transport or disposal.

Mismanaging RSW can lead to significant penalties, environmental damage, and increased project costs. If you’re unsure whether your waste falls under this category, seeking expert support ensures compliance and safer outcomes for your site and community.
