The concessionaire has been granted management rights over the state-owned plants.
The decision will create more job opportunities for people in the state, state governor Bassey Out was cited as saying by domestic media reports.
The handover ceremony was organised at the Ayade Industrial Park Calabar.
The concession terms have been structured under a public-private partnership (PPP) arrangement to keep the factories operational and profitable over the next two decades.
