PAS 402:2025

PAS 402 was written specifically for performance reporting for the waste management industry – encouraging business improvements by providing a standardised methodology for recording performance data and demonstrating management credentials.

This PAS specifies requirements for performance reporting by a waste resource managementorganization.

It requires a waste resource management organization to report:

1. how it conducts specific waste resource management activities
2. the material recovery rates it achieves

It is applicable to waste resource management organizations that have the benefit of an environmental permit, or waste management licence or operate an exempt activity.
