Waste and Resource Recovery

Waste Classification and Resource Recovery

Opterra can provide advice, sampling and assessment of waste for waste classification and resource recovery purposes. Opterra can classify waste into specific groups to allow for appropriate management and disposal at a licensed landfill, as per the waste classification guidelines. 

    To comply with the waste legislation, those who generate waste are responsible for classifying their waste into one of six waste classes based on the level of risk they pose to the environment and human health. These six waste classes include:

    • special waste
    • liquid waste
    • hazardous waste
    • restricted solid waste
    • general solid waste (putrescible)
    • general solid waste (non-putrescible).

    The purpose of waste classification is to group wastes that pose similar risks to the environment and human health facilitates their management and appropriate disposal.

    To help waste generators classify the wastes they produce, the NSW Environment Protection Authority (EPA) has developed Waste Classification Guidelines which are a step-by-step process for classifying waste.

    Generators and waste facilities must ensure they classify their waste carefully in accordance with the procedures in the guidelines. This is because waste can only be taken to, and accepted at, a waste facility which is lawfully authorised to receive, re-use and/or dispose of that classification or type of waste.

    Opterra can also assist organisations with general exemptions for commonly recovered, high volume and well characterised waste materials for recovery or disposal including:

    • Excavated Natural Material (ENM)
    • Recovered fines
    • Recovered aggregate
    • Recovered railway ballast
    • Compost
    • Raw mulch

    Opterra only employs NATA accredited laboratories for sample analysis, and follows strict Quality Assurance and Quality Control (QA/QC) procedures.
