The Central Waste Complex (CWC) is a storage and treatment unit located in the center of the Hanford Site with approximately 300,000 square feet of storage space. The facility has seven large storage buildings, twelve small storage buildings, and five areas for outdoor storage.
 
At the facility, workers store and treat mixed low-level waste, transuranic and transuranic mixed waste, polychlorinated biphenyl waste, and other waste types requiring treatment before disposal. Waste stored at the CWC will be treated and repackaged as required for disposal.
 
For more information, please see the Central Waste Complex Fact Sheet.
