Materials Recovery Facilities (MRFs)

A materials recovery facility (MRF) that processes banned materials for reuse or recycling as part of a responsible unit's (RU) recycling program:

• must meet the general requirements for a MRF;
• must be self-certified with the DNR prior to processing recyclable materials for a RU; and
• must annually renew self-certification by March 30.

MRFs that do not handle or process materials for a RU's recycling program are not required to be self-certified with the DNR.

MRFs that process only one of the recyclable materials, referred to as "Single Commodity MRFs", are conditionally exempt from self-certification provided they meet the general requirements for all MRFs.

MRF Self-Certification

Invalidation of Self-Certification

The DNR may invalidate a self-certification if there are significant discrepancies between what is reported and what is actually found during a DNR inspection. A self-certification may also be invalidated if the MRF fails to submit information required either to the DNR or to RUs.

A MRF can return to good standing and be re-certified if the DNR determines the facility is in compliance and has put in place appropriate policies and procedures to remain in compliance with the requirements in s. NR 544 (3), Wis. Adm. Code. If the DNR determines it is necessary to invalidate a MRF's self-certification, the MRF must notify the RUs it serves of the change in status and of re-certification if/when granted.
