Following are a set of P2 options you may wish to implement. No option is perfect for everyone, but sometimes options that have worked at one facility can work at yours. They might also serve as inspiration.

Reviewed Rubber and Plastics Options

Options below have reviewed by pollution prevention specialists. They are commonly recommended and implemented for facilities.
 
Covering Chemical Containers
Prevent chemical additive leaks and spills during compounding or finishing operations by habitually covering chemical containers.
 
Good Housekeeping Practices
Segregate raw materials and lubricating oils from cooling and heating water, so that pollutants not produced during the plastic molding and forming operation will not enter the cooling and heating water.
 
Reuse and Recycle Process Water
Reuse and recycle process water through a sedimentation tank intended to eliminate the suspended solids in order for process water to be reused
 
Reuse and Recycle Process Water
Reuse and recycle process water through a sedimentation tank intended to eliminate the suspended solids in order for process water to be reused
 
Treatment of Recycling Unit Discharge
Implement end of pipe treatment of the recycling unit discharge.
 
Remove TSS and Phthalates from Finishing Water
Remove TSS in a settling unit and remove phthalates through an activated carbon process.
 
Participation in Operation Clean Sweep (OCS)
A joint effort of SPI and American Plastics Council, a program that includes implementing the following measures: minimizing spills, quickly and systematically cleaning up spills, and appropriately disposing pellets by implementing employee education, through sweeping efforts, improved pellet capture methods, and disposal safety measures.
 
Recycling plastic waste
Recycle single plastic resins and mixtures of plastic resins. Recycling mixtures of plastic resins will result in a lower quality as opposed to recycling single plastic resins.
 
Careful Chemical Transportation Mechanisms
Receive chemicals in closed docks in sealed containers or in bulk rail or truck shipments with minimal spills. Store chemical piles inside the facility to guarantee fugitive emissions are contained within the facility
 
Seal Containers for All Open Materials
Seal open containers to minimize puffing losses when containers are opened. The sealed containers should have air space between the chemical and the container cover.
 
Secondary Containment Mechanisms
Use for all storage containers to protect against leaks and spills.
 
Automatic Dispensing and Weighing Equipment
Use whenever possible for quality control and to minimize waste from spills due to manual dispensing
 
Reduce Toxic Chemical Usage
Reduce the use of toxic chemicals through reformulation.
 
Computer Inventories
Use a computer inventory system in order to reduce the amount of purchased stock
 
Spills and Sweeping Protocols
Ensure the proper segregation of waste by implementing appropriate protocol for cleaning up spills and sweeping.
 
Water Reuse and Recycling
Install a closed loop water heating or cooling system.
 
Substitute lubricating grease for oil
Substitute lubricating grease for oil (especially appropriate for milling equipment) to prevent the contamination of wastewater. Grease has been shown to considerably diminish the amount of manifested waste.
 
Preventative Maintenance on Process, Molding, and
Preventative maintenance can reduce manifested oil and grease waste through waste reduction generated by worn seals and gaskets.
 
Removal of oil from oily wastewaters
Remove oil from oily wastewaters prior to disposal to decrease the amount of wastewater disposed. For example, oily wastewaters can be collected from equipment engine pits and directed through a central oil/water separator before discharge.
 
Segregation and Recycling of Waste Rubber
In some cases, simplifying the segregation of waste streams is as easy as positioning a screen over a portion of the molding equipment so that the waste rubber stock produced during performing operations can easily be separated from oily wastewaters. The waste rubber stock can then be fed back into the process for recycling. In addition, the segregation of cured and uncured rubber can make recycling of the uncured rubber easier.
 
Reclaim and Recycle Off-specification Rubber
Reprocess used rubber products that can be integrated into virgin rubber compounds. Add scrap rubber to coal and wood waste fuels for firing process boilers. Process used rubber products into sheets and various shapes to utilize as athletic area surfaces and other floor covering services. Make it into sheet gasket material or loading dock bumpers.
 
Tracking of Waste Indices
Monitor and track the total pounds of non-recyclable waste shipped offsite per 100 lbs of product and also the total pounds of hazardous water generated per hundred pounds of product in order, and aim for reducing these indices.
 
Substitute or Eliminate (Hazardous Air Pollutants)
Tire cementing and spraying operations and retread and recapping industries can substitute or eliminate HAPs typically used in solvents and cements, because rubber compound components can typically adhere without cement and solvent aides
 
Reuse and Recycle Scrap Tires (those incapable of
Use scrap tires as a fuel or fuel supplement in an array of utility and industrial applications. Grind to use as an additive to asphalt paving materials. Use whole and processed tires in civil engineering. Use cut, split, and ground tires in new products

Unreviewed Options, Use with CautionUnreviewed Rubber and Plastics Options

Options below have not been reviewed by pollution prevention specialists. They are commonly recommended and implemented for facilities.
 
Seek safer less volatile mold release chemicals
Work with vendors to reformulate mold release agents with a water base that contain fewer VOCs and are less flammable.
 
Evaluate Mix Recipe
Periodically evaluate the mix recipes for the vulcanized and non-vulcanized proceses to determine if a lower VOC content rubber mixture can be used to manufacture acceptable products.
 
Automatic Dispensing
Utilize automatic dispensing and weighing equipment whenever possible.
 
Alternative media
Use alternative media for sanblast grit.
