Contaminants in organic waste: Framework and thresholds report

In 2023 the Ministry for the Environment commissioned Eunomia Research & Consulting, Whetū Consulting Group and Massey University to examine issues related to the presence of contaminants in organic waste material streams.

The project aimed to understand and address the challenges posed by contaminants in our organic waste material streams to mitigate risks to soil, human and animal health and expand end markets for processed organic waste.

This framework and thresholds report is one of four reports that summarise the project’s key findings.

The report provides a high-level conceptual framework for managing organic waste contamination and an approach for identifying priority contaminants and thresholds.
