CP Group has been named NWRA's 2022 Innovator of the Year for the company's OCC auger screen. The award recognizes "recycling equipment designers and manufacturers that successfully challenge and advance recycling sector operations. It celebrates innovation in design and manufacturing that increases the effectiveness or efficiency of recycling equipment and operations".

The OCC auger screen is a non-round anti-wrapping and anti-jamming auger screen that does not need to be presorted and creates a finished OCC product. Because the screen is cantilevered, all wrapping materials screw off the end, making it low maintenance with minimal cleaning required. The screen fractionates out the smaller material stream, so sorters only see the larger stream which improves sorter safety by reducing exposure to sharps. The patented non-round attribute of the auger flights creates the agitation needed to produce a clean OCC product.

The machine prototype design was complete in 2017 and the first machine was manufactured in 2019. After months of testing, that prototype machine was installed in the Waste Connections Ecosort facility in Eugene, O.R., which processes commercial material and is still running today.

Over the past several years, CP has invested in its production capabilities to keep up with growing demand. Over multiple years of research, CP purchased a specialized machine with proprietary flight-forming technology.

With this specialized flight-forming machine and CP's manufacturing capabilities, CP is able to fulfill auger screen orders in-house without any outsourcing. This includes the production of the non-round auger of the OCC auger screen that creates the material agitation needed to produce a clean OCC-end product.

The first residential single MRF utilizing a non-round OCC auger screen for the direct and final screening of OCC material began operation in late 2021. The Metro Waste Authority (MWA) MRF in Des Moines, I.A., is, what CP Group says, the first high-volume single-stream MRF in North America to operate without a presort or post sort station of any kind – all removal of non-program material is performed at quality control stations or is the negative sort of the system – which is a 100 percent reduction in labour dedicated to non-program material. This is due to the pairing of the OCC auger screen with the CP primary auger screen.

Several OCC auger screens are currently in production and are in the quote process. CP thanks the NWRA for this award which recognizes the value that CP and this machine have brought to the industry.
