Covanta SECONN recently teamed up with Mystic Aquarium and our SEMASS, Haverhill, and Bristol facilities to create an interactive exhibit showcasing how discarded marine debris can be turned into clean energy. This exhibit, entitled “Covanta Cove,” includes a water feature depicting a local pond, a diorama reflective of a local CT neighborhood, a scale-model of a typical Energy-from-Waste facility, and two giant, mobile claws.
