Highlights and Announcements
New Demolition Debris Diversion Reporting
Starting May 12, 2025, Cook County will transition from Green Halo to a new electronic system for managing and tracking demolition debris diversion plans and waste tickets. While Green Halo has been a valuable resource, the County is implementing a new 3D reporting system to streamline processes and enhance efficiency. This new system will be integrated with the current permitting process, eliminating the need to visit another site.
We understand this change may require adjustments to current practices, and we are committed to supporting impacted contractors throughout the transition. To facilitate this process, we have prepared step-by-step instructions for using the new system, which can be found here.
If you have any questions or concerns, please do not hesitate to contact us at asbestosdemo@cookcountyil.gov .
Thank you for your cooperation and continued commitment to sustainable demolition practices in Cook County.
