As recycling becomes more prevalent in American households, the amount of single stream glass material has become a larger part of our supply base. Many loads require pre-sorting before processing can begin.
Strategic Materials has developed quality improvement tools to accurately assess and process incoming glass. Our goal is to process this glass as efficiently as possible while also ensuring it meets our standards and the standards of our manufacturing customers.
Strategic Materials performs inbound quality inspections and rates them based on the percentage of usable glass, generally clean glass with minimal or no visible contamination, and amount of ceramic, rock, or color contamination.
Our delivery inspection is either by:
- Visual inspection - in the case of Mixed Window Plate (MWP), Clear Window Plate (CWP), whole or 3-dimensional flint, amber, green or mixed color or
- Sample analysis - in the case of 3 Mix (single stream) glass from a Material Recovery Facility (MRF)
Better supply = better pricing
Our pricing for incoming glass is now tied to the quality of the supply. Key factors that drive processing:
- Non-Glass Residue % and local landfill rates
- Undersize %, plant capabilities and local disposal options
Significant variance from these color percentages may reduce or increase the value of cullet stream.
