At its Bay Saint Louis, Mississippi facility, Commercial Plastics Recycling, Inc. is proving that sustainability and profitability can go hand in hand. With the help of a WEIMA WLK 10 shredder, along with a WEIMA WLK 6S shredder, this post-industrial plastics recycler transforms massive volumes of PET purge into clean, reusable material—reducing landfill waste while powering a growing, efficient recycling operation.
Reliable, Dependable, Profitable: How CPR, Inc. Uses Shredders to Turn Plastic Waste into Sustainable Growth
Turning Industrial Waste into Manufacturing-Ready Feedstock
Commercial Plastics Recycling, Inc.’s Mississippi facility works closely with nearby petrol chemical companies, allowing them to receive the excess purgings from these large area operations. On average, CPR, Inc. receives between 3 to 7 truckloads per day of PET purge material, typically arriving in batches of 35,000 to 40,000 pounds. These are large, dense chunks of plastic—often weighing 150 to 200 pounds each—that are difficult to handle without specialized equipment.
About Commercial Plastics Recycling, Inc.
Originally operating from a single warehouse, CPR, Inc.'s Mississippi location expanded to include a second refurbished building to accommodate growing volumes. The added space allows for more efficient storage and processing, improving turnaround times and throughput.
Each week, the Mississippi site now ships about nine truckloads of shredded plastic, with each truck carrying around 42,000 pounds. This translates to more than 18 million pounds of recycled plastic per year that are diverted from landfills and reintegrated into manufacturing processes.

Where the shredding begins
Once the purge material reaches the CPR, Inc. plant, it’s routed to the WEIMA WLK 10 single-shaft shredder, which runs 8 hours a day. This machine consistently processes between 14,000 and 18,000 pounds of material per day, totaling up to between 280,000 and 360,000 pounds per month. The output: clean, uniform 3/8-inch plastic pieces that are packaged and shipped out to manufacturers for reuse.

Adding Redundancy and Flexibility with the WLK 6S
To further strengthen their operations, CPR, Inc. recently invested in a second WEIMA machine—the WLK 6S single-shaft shredder. This addition plays a vital role in both reliability and scalability. With the WLK 6S on site, CPR, Inc. has the flexibility to maintain steady production rates even during scheduled maintenance on the WLK 10. Additionally, when customer demand spikes, the two machines can run together, boosting daily throughput without compromising quality.

Like the WLK 10, the WLK 6S produces 3/8-inch particle sizes, ensuring consistency in output across both machines. The added capacity gives CPR, Inc. the confidence to meet customer expectations while continuing to grow.
Maximizing Equipment Performance with Preventative Maintenance
To keep their equipment in peak condition, the CPR, Inc. team follows a disciplined maintenance schedule. On the WLK 10, knives are checked every 100 hours of operation and either rotated or replaced as needed. Sharp knives and consistent upkeep are essential to maintaining high throughput and minimizing downtime.
Thanks to this proactive approach—and now, the added redundancy of the WLK 6S—the team can return to full production quickly and meet daily processing goals without interruption.
