It includes a requirement to operate a reuse and waste minimisation service in line with the council’s sustainability objectives.
Amey chief xecutive Mel Ewell said: "The council has a strong commitment to sustainability and we aim to support this by dealing with waste for the Island, on the Island and thereby delivering a local service with local jobs.
"We want to deliver innovative and good value environmental and waste services, which meet the needs of the residents and also save the council money."
