Polystyrene Cooler Return Program



 Polystyrene Recycling Program

US Customers Only

For our customers in the United States Sigma-Aldrich is pleased to offer a polystyrene cooler return program to help reduce waste sent to landfills. To utilize this program you just need to follow three simple steps.

  1. After you receive your order from Sigma-Aldrich remove the product from the cooler, making sure to leave the empty cooler in the box.
  2. Put the cooler lid back on the container and then flip the flaps of the box so the pre-paid postage stamp is on the outside of the container. Seal the container using shipping tape.
  3. Drop off the box at any location where the United States Postal Service picks up mail.

The box will be returned to Sigma-Aldrich to be inspected and returned to service for another order.

Sigma-Aldrich completed a third party verified Life Cycle Analysis of our polystyrene cooler return program and found conclusive evidence that the return of the polystyrene coolers help to decrease CO2 emissions related to the use of polystyrene coolers.
