Don Don Donki, the Japanese discount retail store chain, announced they are now taking back their own ice packs for reuse. 

DDD thoroughly cleans and sanitizes the packs for reuse:

  1. At the end of each day, the closing shift cashier collects all the used ice packs and soaks them in a pail of water to remove any residue or debris. 
  2. Then the following morning, the opening shift cashier will wipe the ice packs dry and sanitize them using a food-grade sanitizer solution. 
  3. Finally, the sanitized ice packs are placed back in the freezer to re-freeze for continued use.
