After bulbs are returned, they will be transported to a processing plant. The processor will crush the light bulbs under controlled conditions and the components will be separated. The glass and metal will be recycled and the mercury-phosphor material will be sent for retorting (a heating process that results in usable mercury). CFL ballasts may include plastic and ceramics and the destination for these materials may vary by processor. The program will strive to reach the target of recycling 100% of the material recovered.
