How Single-Stream Recycling Works

Large metering bin is loaded with mixed recyclables at the start of the single-stream system.


Metering bin and incline conveyor moves materials to pre-sort line

Pre-sort line. Materials too large for the downstream system to process are removed by hand prior to entering the OCC separation screens.

A second set of polishing screens continue separating fibers from plastic bottles, tin and aluminum cans, and aseptic containers (paper cartons).

Final polishing screens remove any remaining fiber and send it to the fiber sort line.

Green Eye high intensity lighting system. Floods the accelerator belt with light enabling vision system to collect the data it needs to fire air jets and remove desired recyclable products.


Green Eye Optical Sorting Systems high speed accelerator belt. Travels at 500 feet per minute and evenly disperses material load so that optical sensors can identify isolated containers for sorting.
