Meeting the challenge of eliminating plastic waste
PSC’s mobile packaging units offer a variety of resin waste processing capabilities, including product drying, angel hair and ferrous material removal, product mixing and transferring, packaging and remote sampling.
Some of the services offered include:
- Factory assessments / audits.
- Development and implementation of the OCS sustainable development plan.
- Drafting of procedures and development of checklists.
- Routine “pellet patrol” inspections.
- Employee training and sustainable development awareness campaigns.
- Resin waste collection services on site via dedicated teams and on call.
- Purchase / sale of scrap metal to generate income for customers.
- Packaging, storage and recovery of scrap metal through additional treatment.
- Comprehensive, data-driven monthly progress reports.
- Environmental impact assessments.
- Stakeholder presentation materials.
PSC strives to identify and implement waste resin collection and treatment solutions to maximize their value.
“It’s an important part of our sustainable development business model, to help promote a circular economy in which nothing is lost and everything is transformed,” added Bryant. “We are looking for new recycling opportunities for our customers and other ways to extend the life cycle of pellets and improve the quality of scrap for better resale value.”
For example, at one site, PSC sustainability technicians sucked up pellets scattered over thousands of feet of railroad tracks.
“We use a sieve to separate the pellets from the ballast rock, and then we use special processes that we have developed to clean, sort and dry the pellets,” said Chris Lendo, vice president of sustainability at PSC. “Most of this resin waste can now be recycled, generating income for the customer. Prior to the implementation of these new processes, most of the material was disposed of in a landfill. “
The right equipment for the job
PSC has made a significant investment in specialized equipment for this new industry, including:
- High discharge vacuum trucks, eliminating the need for dangerous ramps.
- Mobile packaging units with unique capabilities such as product drying, angel hair removal, ferrous material removal, product mixing, product transfer, remote packaging and sampling.
- Custom-made dumpsters that can be strategically placed in a site’s collection areas.
- Bulk pneumatic trucks, vans and grain trailers for loading and transporting the recovered resin.
- Trucks and tractor-trucks owned and operated by the company for the movement of products.
On July 1, PSC opened a new sustainable warehouse located in the Port 10 Logistics Center in Baytown, Texas. The nearly 70,000 square foot facility provides ample storage space for up to 7 million pounds of packaged goods, with one acre of parking space for the company’s sustainability equipment.
“Shipments of plastic waste are received at the warehouse where the materials are processed, quality tested and packaged through a semi-automated conveyor and packing line into gaylord supersacks and boxes,” Lendo said.
PSC offers an optimized network of satellite warehouses located within 50 miles of most resin producers in the US Gulf Coast region to provide responsive and reliable services.
“In addition to the packing operation, we also operate our 24 hour dispatch center from the Baytown warehouse so that we can get the necessary personnel and equipment on the road quickly to respond to spills. emergency, as well as to support turnarounds and project shutdowns, ”Lendo added.

SUSTAINABILITY SOLUTIONS FOR COMMON MANUFACTURING PROBLEMS
PROBLEM: The “angel hair” created during the granulation / transfer process gets loaded into the railcars, resulting in quality issues and lost revenue for resin customers, with materials often rejected, returned or downgraded.
SOLUTION: Process the product in the mobile packaging unit to remove angel hair and restore it to top quality by circulating the material through a closed loop fi lter system before reloading it into the railcar.
PROBLEM: During the car wash process, the resin remaining in returned empty cars is washed into sumps and contaminated, resulting in devaluation of the recovered product and potential loss to the environment.
SOLUTION: Strategically position a custom designed wagon bead vacuum reclamation system prior to the car wash process to reclaim remaining resin in cars, keeping it clean and dry for improved quality.
PROBLEM: Resin that escapes from process containment is dispersed on soil or in wastewater streams, resulting in contamination and devaluation of recovered product and potential loss to the environment.
SOLUTION: Operation Clean Sweep “pellet patrol” to prevent resin from spreading throughout the plant, using PSC’s fleet of high-dump vacuum trucks with advanced technology and grounding systems integrated.
