Pellet Management Best Practices

We have many layers of protection in place at our facilities to prevent loss of containment. Some of the company’s plastic pellet management activities may include:

General Facility Practices

  • Properly designed drainage system that directs all flow that could contain pellets or flake from the facility to dedicated sumps or recovery ponds where continuous filtration systems are utilized to remove pellets or flake from water
  • Sieves and screens located prior to water discharge points that are routinely monitored
  • Screens placed on storm water drains to ensure that residual pellets do not enter storm water
  • Collection and recycling of all recovered pellets, powder and scrap material into dedicated collection containers

Loading and Unloading Areas

Loading and Unloading areas

  • Utilization of closed loading systems that minimize pellets lost during loading
  • Cleaning stations (air or water) for outbound hopper cars and trucks to removal residual pellets
  • Loading areas are paved to facilitate cleanup of spilled pellets
  • Utilization of vacuum systems and catch bins during unloading activities, transloading and sampling
  • Service providers on-site which provide cleanup and collection of internal pellet and powder spills
  • Caps are reinstalled and sealed on hopper cars after unloading or sampling activities
  • Purge transfer lines and hoses prior to disconnecting from hopper car or truck

Production Area

  • Procedures in place to respond to and clean up spills
  • Use of tarps and vacuum during maintenance activities that are conducted on flake and powder handling equipment
  • Dedicated pellet, powder and scrap collection containers close to key equipment in facility
  • Plastic powder or flake containers covered before transport within facility
  • Use of bag house filters to prevent powder from entering atmosphere


All best practices that have been developed for converters have been collected from our Performance Pipe division.

  • Use dedicated bins for plastic debris from floor sweep and other activities that have covers
  • Place spill kits in strategic areas in facility for quick cleanup of spills
  • Vacuums strategically placed in facilities that are lightweight and easy for employees and contractors to utilize
  • Regular inspections conducted on transfer piping
  • Performance of regular housekeeping rounds
  • Ensure equipment used produces minimal plastic debris (Ex: utilize saw technology that minimize creation of fines, etc.)
  • Concrete berms around facility perimeter to prevent any residual debris from entering grassy or rocky areas
  • Properly sized screens on storm drains and outfalls to serve as last line of defense to ensure plastics do not enter waterways
  • Keep all containers holding plastic debris covered and in areas where they are not exposed to the weather
  • Ensure no plastic debris is being landfilled; all plastic debris should be handled by an appropriate recycler to avoid risk of loss of debris during transportation to landfill
  • Utilize screens on closed loop water system
  • Utilize dedicated pellet containment bins to collect pellets that are covered and stored out of weather
  • Ensure forklift operators responsible for transporting boxes are trained on how to respond to spills if they occur
  • Samples only taken over paved areas, never over rocks
  • Products are blown out for fine removal before being transported to laydown area
  • Filters are emptied directly to plastic debris containers and vacuums are kept next to activities to clean up any spills prior to filter changeouts
  • Ensure hopper cars and trucks are unloaded completely by cycling the valve while under vacuum before disconnecting hoses
  • Purge transfer lines and hoses prior to disconnecting from hopper car or truck
