The aim of the PPPL Plasma Sterilization Project is to develop a method for quickly sterilizing food, beverage, and other thermoplastic containers using a plasma discharge. The goal is to sterilize thermoplastic containers with less than two seconds of treatment in a food production-line environment. PPPL's innovative plasma sterilization technique uses energetic ions to destroy bacterial spores, which are the most difficult microorganisms to eliminate. The technique should be effective on other microorganisms as well.
