University of Colorado students, faculty and staff throw their recyclable items into recycling bins across campus.
Step 2: Materials Collections
Facilities Management recycling crews collect recyclables from bins across campus and deliver them to the Grounds and Recycling Operations Center
Step 3: The Dumper
The bins are loaded into a hydraulic dumper where they are raised and slowly tilted so that the materials spread across a conveyor belt.
Step 4: On the Sorting Line
Students sort through materials to pull out contaminants and prohibitives (which we call a “negative sort”) in order to upgrade the quality of the recycled material that leaves the facility.
Step 5: Special Materials
During the sorting process, hard to recycle materials that are contaminants in regular recycling are pulled out and organized into special bins to be dealt with directly. These include: batteries, electronics, CDs, and many other miscellaneous items.
Step 6: The Weigh In
Processed recycled materials are weighed to ensure accurate accounting of the campus diversion rate. These metrics are used later used to determine how much material has been diverted from landfills each year.
Step 7: The Tipping Floor
Sorted materials are then taken to the tipping floor to be dumped into large roll-off truck beds.
Step 8: The Shipment
Once they are filled with sorted recyclables,the roll-offs are shipped to the local Materials Recycling Facility (MRF) where some materials are bailed directly for resale and some are sorted once again in preparation to be sold to market and turned into new materials.
